How to Determine the Best Bandwidth Solution For Video Conferencing & Multi-Media Applications

Michael Lemm — Fri, 25 Mar 2011 19:32:04 +0000

Your business intends to make extensive use of video conferencing and multi-media applications. How do you determine what bandwidth solution (T1, DS3, OCx/Sonet, etc.) would best meet your needs and incorporate that decision into your network cover these applications?

I’d say that it depends on what kind of service and QoS you are looking at. For example, when you say “video” you mean video conferencing and not something like VoD. The Bandwidth requirements will vary according to your service requirements.

For example: For IPTV services, the image quality depends on the encoding deployed: MPEG-2 consumes approx. 3.75 Mbps, whereas MPEG-4 needs approx. 2 Mbps for the same high-quality image production. Also broadcast TV is delivered using IP Multicast which makes the bandwidth required dependent on the number of channels offered and the encoding rate. 200 channels of MPEG-2 in standard definition will take approx. 750 Mbps of bandwidth. VoD, on the other hand, is a unicast per-viewer channel. 1000 standard definition VoD users will need appro. 3.75 Mbps.

The QoS requirements for video conferencing using H.323 (SIP could be different again) can be planned on the “Rule of 75″ as follows: Calculate the minimum bandwidth required by each of your applications ( e.g., video, voice, data). The total of this bandwidth is the minimum requirement for any given link and it should consume NO MORE than 75% of the total available bandwidth on the link. The 75% rule makes allowances for bandwidth required for over head traffic, such as routing, Layer 2 keepalives and other applications, such as, email, HTTP etc.

So, Capacity planning for H.323, should look like something as follows:

Video data + 20% = bandwidth required.

Example:

Video data rate: Bandwidth Required:

512 kbps = 614 kbps
1.5Mbps = 1.8 Mbps …

For issues such as number of concurent users and more stuff on video conferencing you can perhaps consider looking into Cisco’s solutions offered and also TANDBERG boxes.

Cisco considers anything 766Kb to be a “slow link” for VOIP. Also you need to consider the criticality of the sites so you may need two separate connections. All multi-media applications run on top of your other applications so QoS only allows a preference of who goes first.

You need a good baseline of non-multi-media applications (VOIP). So bandwidth needs to be able to handle all necessary applications in the network.

Also, you’ll need to remember that the bandwidth aggregation at the Data Center needs to meet or exceed all inbound remote site traffic. In other words, if I have three remote sites all with T1s. I’ll need more than one T1 at the Data Center to manage the traffic. Remember unless this is a greenfield then baseline, baseline, baseline!

When it comes to streaming video, bi-directional – you are going to have to consider the quality of the compression you are planning to use. If you are planning on using high definition video 1 direction it is recommended to have at least 2MB in the direction of the video being accessed.

So if you are streaming video to your computer then you need to make sure that you get 2MB download capacity. Also, another thing to keep in mind is latency and loss of packets. I would recommend staying away from wireless for this type of application as it will add latency and cause issues later. DS3 bandwidth and anything higher may be over kill, but would easily be able to handle your demands.

Without knowing specifics, it is hard to provide a precise answer, but, one can still specify a systematic method for calculating required bandwidth. Once you know the bandwidth requirement, then it is all about negotiating the most economical way to order that bandwidth from a network provider in the area.

Here is what I would suggest:

1. Calculate the peak external link bandwidth requirements (inter-office data transfer, video conferencing, email transfers. With attachments running in tens of megabytes, email traffic can’t be ignored these days.).

2. Real time applications being mostly jitter and delay sensitive – so you have to make sure that you will have enough bandwidth when they need it. The bandwidth of video depends on the mpeg profiles used (without going into specific, generally 1.5 Mbps can give you very good video on a PC (equal to VCD quality). HDTV images can take about 20 Mbps – but that is domain more reserved for IP TV service providers). Most current users of interactive video communications will be happy with the images coded and transmitted @ 512 Kbps. This includes audio and video as well as control signaling. So, one should provision at least 512 Kbps per video stream, and more the better (I would say 1.5 Mbps is the good if you are a big organization and use a large TV for video conferences)). So, multiply bandwidth for a single stream by the number of parallel streams required. Now that determines the total peak real time usage.

3. There is no specific rule – but wise men with experience advise to keep the peak real time within 60 to 75% of network bandwidth available leaving the remaining capacity for background traffic. In a small organization of 5 people – it is easy to tell people not to download gigabyte attachments when video conferencing is going on , but in larger organizations it is hard to enforce such things except with router policies (assuming they have QoS support), and you can deal with occasional unhappy users.

4. Now, once you know your bandwidth requirements, it is time to talk to the network operator how they can provide that bandwidth in the most cost effective way.

Do You Have Leathery Skin? Solve This Problem Right Away!

Fri, 25 Mar 2011 19:28:19 +0000

Nobody wants to have a skin that resembles a tree trunk. But leathery skin is a real problem that many people have to deal with. If you are one of those people, you should find out how you can fix this problem right now.

Here are some effective treatments that can solve leathery skin:

1. Blend one medium-sized carrot and add two tablespoons of honey. Apply the mixture on your skin. Leave it there for about an hour before washing it off. Carrot contains beta carotene. With the help of this nutrient, you can enhance the healing properties of your dermis.

Honey can deeply nourish and hydrate the dermis. It has the ability to make the skin softer and smoother.

2. Try using lemon juice. This can actually help make skin tissues softer. It also improves the structure of your dermis. Apply raw lemon juice on your dermis. Leave it there for 30 minutes before washing it off.

Lemon juice can also be sipped daily. This contains Vitamin C that can encourage the re-growth of collagen fibers. It can help improve the vibrancy of your dermis.

3. Try applying almond oil to the affected parts of your dermis. This oil is a good source of bleaching agents. But in addition to that, it can also nourish your dermis ad make it feel softer and smoother. It has the ability to ward of excessive dermis roughness and dryness.

4. Try using aloe vera pulp. This contains moisturizing and anti aging properties. It can instantly solve the aging problems of your skin. It also works well in moisturizing the skin. Massage aloe vera pulp gently on your dermis. Let it sit there for about an hour before washing it off with lukewarm water.

Aside from these remedies, I highly recommend the use of a natural anti aging moisturizer. You need moisturizers to properly hydrate the skin and bring back the youthful functions of the dermis. Look for a product that contains CynergyTK, Phytessence Wakame and Manuka Honey.

CynergyTK is an ingredient that contains a hefty amount of keratin. Keratin plays a major role in the regeneration of collagen fibers. It can make the skin look younger and suppler.

Phytessence Wakame is a type of Japanese sea kelp that can prevent the sudden loss of hyaluronic acid. This acid is vital for the lubrication of collagen fibers. It can hydrate the inner layers of the skin.

Manuka honey has humectant properties that can lock moisture in skin tissues and duplicate the moisture-producing functions of the dermis. This also works in preventing the rapid aging process.

And now I would like to invite you to visit http://www.goodhealthyskin.com to find out which are the anti aging products you should use in order to achieve clearer and radiant looking skin.

Optical Fiber – Types Of Cable And Their Uses

Wed, 19 Jan 2011 09:28:05 +0000

Optical Fibers are thin transparent fibers that transmit data using the principle of light refraction. Single mode, multimode and plastic optical fiber are the different types available. They differ in terms of speed and distance, and find uses in various applications depending on the speed and distance requirements.

Optical fiber refers to a thin, transparent, thread like fiber that is used to transmit light from one end of a cable to the other. These fibers are present in cables used for fiber optic communications to transmit data at higher bandwidths, faster speeds and longer distances using the principle of refraction of light. They also find application in fiber optic sensors and as light guides in medical equipment. As these fibers are more flexible compared to metal fibers, they can be bundled together easily to form cables. Optical fibers are more efficient than a metal fiber due to the reduced transmission loss, high tolerance to electromagnetic interference and low cost of maintenance.

There are three different types of Optical fiber – single mode, multimode and plastic or polymer optical fiber. A single mode fiber is relatively narrow with a diameter of approximately 8.3 to 10 microns. It has only one mode of transmission and a higher bandwidth but can work only with a light source that has a narrow spectrum width. It also offers about 50 times more distance than using a multimode fiber, but this comes at a higher cost. It is used in applications that require transmission of multi frequency data using a single cable such as telephony or cable TV.

A multimode optical fiber has a slightly larger diameter than a single mode fiber – between 50 to 100 microns. They are usually used over medium distances and have a bandwidth between 10 and 100 MBS for distances up to 2km. Common uses of the multimode fiber due to the lower costs are in backbone infrastructure in buildings or campuses.

The plastic or polymer optical fiber was traditionally made from acrylic, but nowadays is made using polymers. They are similar to the glass fibers used in single and multi mode fibers but the core size is around 100 times larger. These cables, due to their low speed and suitability for short distances of up to 100 meters, are most commonly used in networking for homes, cars, digital home appliances as well as industrial networks. They are also used for high speed wiring requirements for data centers and building LAN. Other applications include video surveillance and Ethernet.

While determining which type of Optical Fibre to use, it is essential to take into consideration factors such as transmission speed, distance, costs and usage in order to decide whether to use single mode, multi mode or plastic fiber.

Renting Commercial Office Space – Top 10 Mistakes

Wed, 19 Jan 2011 09:27:57 +0000

Moving your business into new office space sounds exciting but there are a number of pitfalls that many businesses have found which has proved expensive and resource-intensive to rectify. Here are a few key areas that you need to think long and hard about before you may the big move.

Office Size
If you’re unsure about the size of the office space you require then don’t rent somewhere based on looks and facilities alone. If find an office that is too small you will have to move again in the near future if your business begins to grow. If you office space is tool large you will end up paying for space that you are not using which is inefficient and could prove a costly mistake.
A basic rule of thumb is to use 7 square metres for each employee. If you have a call centre then you may be able to get away with less. Don’t take more space than you need to unless you are planning to expand or the space is offered at a fantastic rate.
If you are a small business you could try renting serviced offices until you find the right location and set up for your requirements. Serviced offices are slightly more expensive but tend to have shorter leasing agreements which means you have the flexibility to move should you need to. There are plenty of serviced office locations around so finding a lease to suit you should be fairly easy.

Cost of Premises
Make sure you never rent offices that you do not think you can afford. Business can fluctuate rapidly throughout the year so don’t use your current trading as an indication of the future. Changes out of your control, such as the increase in VAT, can have a considerable impact on your business so be wary and only rent what you can afford. It is better to know you can afford to relocate to larger offices further down the line than having to see out an expensive leasing contract that you can’t afford. Don’t get carried away by the glamour of some offices. There are plenty of opportunities to negotiate down on price.

Location of Premises
When moving into your new office space you need to think carefully about the location. Ask yourself if this is a good location for your business, its future growth, customers and your employees. If you rent office space in a cheap location with limited transport links, below par facilities and with a poor crime record you will struggle to find staff who will want to work there. Finding the right location is very much a balancing act. Try to weigh up costs against what you need and what your employees expect.
If your new office space is outside a main city you may struggle to find a high calibre of staff and you may also lose your existing staff. Cities do act as a magnet for talent and the more central you are, the easier it is to find them. Obviously, this comes at a cost.

On the flip side, there are also benefits to being situated just out of town. Many young people cannot afford to live in the centre of a city so basing your business on the outskirts can also be advantageous. Any further than 10 miles from the centre of town, however, can limit your appeal.

Poor Transport Links
Nobody likes spending 2-3 hours getting home from work each day. Therefore, make sure that you new offices suit you and your employees. If you already have people working for you, try to be as accommodating as possible to their needs and their family’s needs. You will never please everybody but if you can base your decision around your most valued employees then you give yourself the best chance of keeping them.

Regardless of common belief, cities have very good transport links but due to the sheer number of people, some days feel like a complete ‘rat race’ and journeys can take far longer than expected. Think about transport back in the event of bad weather or disruption. Can your employees get into work via train, bus, tram, bike, car share, etc?

Also think about your customers. How often do they visit your business premises? Does a location with poor transport links hinder the perception of your business?

Poor I.T Infrastructure
So you have now found the office that you think is perfect for your business but have you investigated the I.T and telephony infrastructure? Before you move into your new office space you need to make sure you have the systems to support your business. If you have no or limited broadband access, limited phone connections or connection points, you business may suffer as a result. Installing new systems and terminals is not a 5 minute job so make sure your new offices have, at the very least, the same set up as your current location. If you overlook this factor you could frustrated your employees and lose your customers. Do not underestimate the potential damage caused by a poor I.T infrastructure. Try to negotiate this before moving in if the current systems are of a poor standard.

Limited Parking
If you are based in a city it is highly probable that some of your employees will travel to work by car, unless you are in the congestion zone that is. Parking is a serious considering for those who live away from easy accessible transport links or for those who live further out of town. Make sure you ask your existing employees how they plan to travel to work and see if you can negotiate parking spaces into the price. If you have forecasted to grow your workforce then remember to do the same with your parking allocation. Expecting employees to pay to park on a daily basis is not viable. How your workforce travel into work is not necessarily down to you but making sure they are happy when they reach work is. Try to research other local parking facilities available and maybe try to share parking spaces with a neighbouring business.

Poor Natural Light
This sounds like an obvious one but nobody can function effectively in a poorly lit office with no windows or limited light. Basement offices can seem like a good idea but lack of natural light, especially in the winter months, can depress your workforce. Light is important if you are to maintain a good mood in the office and a positive environment. Make sure your new office space has plenty of natural light and also invest in artificial lighting to brighten up the place. Plants will also help to maintain a positive atmosphere.

Lack of Security
Your staff should be like your family and your belongings valued like your essentials at home. Therefore, high level security should not be underestimated. Make sure you back up everything all your systems information in another location and invest in an alarm system that will trigger an alert to the police within seconds should there be a break-in or fire.

Make sure your doors are reinforced; your fire doors are locked at night and your windows are securely fastened and can withstand a potential break-in. You should also check for rotten frames or corrosion that could lead to windows or doors being easily removed by burglars. Security cameras are also recommended so you can record evidence in the event of a break in.

A break-in can seriously damage or even ruin your business. Make sure you take the correct steps to protect it, especially on the day you move in. Some burglars will watch you move in and then strike before you are settled. Don’t be a victim!

Poor Disabled Access
Every business premises should have easy disabled access in and out of the building. Without these access points you may limit yourself with regards to attracting new talent so make sure you have ramps, toilets and lift access if applicable. The Disability Discrimination Act states that you must make sure you have facilities of the same standard for people with disabilities as you have for those without. If these facilities do not already exist then try to negotiate the installation with your prospective landlord.

Unsafe Location
If you want to attract strong talented staff then you need to make sure your office location is a safe environment for them to travel to and from. Therefore, research your preferred choice to ensure your staff will be safe when they leave at night. Remember, winter months can be dark, especially if people leave the office late so easy access to local transport with strong street lighting should be sufficient.

What Is Hotdesking?

Wed, 19 Jan 2011 09:27:19 +0000

The new age professionals are fully equipped with the gadgets like laptops, Blackberry and mobile phones. With all the gadgetry they are in a position to setup the office just anywhere. The employees who telecommute are well versed with the problems they face especially in terms of the technology. The employees who work from home are disturbed by many things while they are working, the things like attending to children, domestic chores, or just not willing to work can lead to a big time decrease in the productivity of the employees.

Hotdesking is the answer to all those problems. Hotdesking is the way in which the employees are encouraged to share their workspaces and other office equipment on “as-required” basis. The small business can invest onetime money on the technology and mobile office equipment instead of the traditional office equipment and they can be rest assured about the benefits and the profits. With the advancement of the technology telecommuting is become very easy. The employees can work from home and they can login to the company’s secure network within minutes. This setup ensures that there is lot of space created within the office so that the employees can reserve the space according to their need. The concept of Hotdesking is especially suitable for the companies who have their office in geographically dispersed area.

Today there are two ways in which the concept of Hotdesking can be implemented.

Traditional – There can be formal and traditional desks with complete office setup be established and the people who are Hotdesking will come on the designated days and use the office equipment to complete their work. The printers, faxes and other equipments are also provided by the companies.

Informal – In this way of informal Hotdesking, the employees are given an option of using the seats in the office as they are available. There are generally laptops which are issued to the employees and they commute using the wireless telephony.

We now list for you some of the areas which can be considered for revamping if you are planning to implement Hotdesking in your company.

The cubicles need to be designed in such a way that any computer can be connected to it.
The telephone services to be configured in such a way that, the people who login to that particular computer should be able to use it.
Personal or shared storage and filing facilities can be provided.
Meeting room is also needs to be created as the people who are using Hotdesking will definitely need the meeting rooms to discuss the plan.
A booking system, automated or manual is also needed to be setup. This setup will come in handy for the employees to book the desk and other office equipment as and when they are coming to the office.

It is highly recommended that you conduct a detailed study of your facilities and also consult your employees before you plan to implement the concept of Hotdesking in your company.

HYDRATION – Replacing Body Fluids

Wed, 19 Jan 2011 08:11:40 +0000

The body is composed of 60 percent fluids of your total body weight and 70 percent of your muscles. The fluids are comprised of water and other bodily fluids, such as lymph and synovial fluids. During the course of our daily activities, the body constantly loses fluids in perspiration and through urinating. How much of these fluids are lost will depend on our activities and the temperatures that are prevailing at the time. During the summer months especially, we tend to be more active in sports, gardening and traveling more in the heat. The greater the activity we indulge in, plus the higher temperatures will cause us to sweat more. Sweat will evaporate on the skin helping your body to cool down. This will also occur even during the winter months when the temperatures are lower. However, it is during the summer months that the body is at greater risk for it to become dehydrated. The greater the amount of sweating results in a greater amount of the body’s electrolytes being lost. Electrolytes consist of many minerals needed to run the body on an efficient level. Without these electrolytes, the body develops heat exhaustion and rapidly a progression of symptoms will occur lacking the proper hydration. Such occurring symptoms are:

Headaches.
Thirst.
Sweating increases at a profuse level.
The skin becomes clammy.
The individual can feel chilly and start to shake.
The individual will become nauseous.
They develop dizziness.
The heart rate increases.
The muscles will start to cramp.

All of the above develops when the body cannot maintain its core temperature of 36 to 38 degrees C. and heatstroke becomes imminent. As you can see there is a very narrow band that the body must maintain its normal temperature range, and to maintain the normal range, you must replace the fluids that are lost. To replace the fluids it is important that you drink enough water throughout the day. It is not necessary to drink a glass at one time. You should sip more throughout the day, drinking at least 32 ounces daily. If you engage in strenuous activities and sports, you should drink even more. If you are very actively engaged in a sport, and are sweating profusely, you should drink at least 8 to10 ounces of water every 10 to 15 minutes. Some athletes will take salt tablets, but that can be an irritant to the stomach. It is much better to use a sports drink such as Gatorade that contains the needed electrolytes. If you know you will be engaging in strenuous sports or other activities, start hydrating before hand, and keep drinking while you are engaging in these activities. Be sure to wear the lightest possible clothing. A mesh type of material will allow more circulation of air. The clothing should be loose fitting and allow the sweat to evaporate. Choosing the time you engage in the sports or other activities is very important. The greatest risks are during the middle daylight hours when the sun is at its peak. Therefore try to confine you activities during the early morning and late afternoon hours when temperatures will be cooler. Drinking enough water has a great many benefits that will enhance your health other than preventing heat exhaustion and heatstroke. These benefits include:

Prevention of constipation by softening stools.
Prevention of kidney stones by constantly flushing the kidneys and diluting acids and the calcific deposits that are the causative factors in forming these stones.
The dilution of these acids will also prevent gout.
Water nourishes the largest organ of our body, the skin. It keeps the skin supple and clear by replacing needed moisture.
Water helps regulate the body thermostat and keeps the temperature regulated. It also balances the body’s electrolytes.
People who constantly have dryness of the mouth, eyes and mucous membranes will find it very advantageous to sip water all through the day.
Helps in the digestion of foods and the absorption of the nutrients that the body derives from the food we eat.
Can prevent muscle cramps even when not engaging in strenuous activities.

Hydration is simply one of the most important things that are needed by our body to maintain its optimum health, appearance and ability to function at a vigorous level.

Problems Faced When Using VoIP

Wed, 19 Jan 2011 08:11:05 +0000

There are still a few wrinkles which need to be worked out in VoIP mainly because it’s a relatively new technology and the standards for its operation haven’t been set yet. Businesses and retail users have very different patterns of VoIP implementation and the problems faced by the two are different. In this article, we look at some of the common issues faced by both.

Bandwidth
Most individual home users have more than enough bandwidth to be able to handle the VoIP traffic. Even so, they need to be careful when downloading large files as this can compress the available space for VoIP to a trickle. The real problems come when working with businesses who have multiple IP phones because it’s so easy to over stress the system. Bandwidth denial must be the first problem you check for.

It’s advisable to manage VoIP traffic using network tools such as a Virtual LAN or VLAN and implement QoS parameters such as jitter, packet loss, and latency. Certain hardware such as Cisco’s will help you do this automatically.

Configuration problems
For home users, this is the most common headache. Because VoIP isn’t “built in” to the infrastructure, we have to do a bit of setting up ourselves and depending on your Internet configuration, firewall and operating system, many things can go wrong. Ports for example have to be opened up depending on what provider you’re using. Without this, your firewall won’t know what the traffic is and may block it.

When you’re using an SIP proxy, you have to be sure you’ve entered the IP address or the server name correctly. Every SIP client for example has a configuration setting where this has to be entered and since there are so many clients, so many providers, so many mobile phones and operating systems, there’s no single way to inform users how to do this.

Power Issues
One often overlooked drawback of VoIP is that it’s entirely dependent on your Internet connection. When your power shuts down for example, your VoIP system goes down too. Most power outages are only for a few minutes and if you’re a business you surely have a good UPS system in place, but for home users it means being unable to contact anyone in an emergency if the lights are out.

In spite of these issues, VoIP is fast gaining acceptance and standardization is also taking place across the board. In the foreseeable future, VoIP will be just as widespread as the PSTN phone system currently is, leading to a cheaper and more flexible communication regime for all of us.
