Go Green in Business | Benefits of HD Video Conferencing by Layer47


Most of us try to do our bit in saving the planet and over the years we have become fairly conscious of being “eco-friendly”. Changing behaviour is easier to manage on a personal level, but what about in terms business operations? Good news is that you do not have to chain yourselves to trees outside the office to demonstrate a commitment to the environment! :)


Play an active role in the Video Conference revolution and you can reap the rewards of high definition video communication whilst boosting your brand with “green-credentials” and participating in a global effort to reduce carbon emissions and protect the ozone layer.


The benefits of Video Conferencing technology are clear, delivering a cost-effective and green alternative to travelling to meetings. Less time out of the office means more time making decisions and more time on projects, resulting in an increased rate of productivity. Not to mention the reduced cost implications, saving on expensive flights, car hire, hotel rooms and meal costs.


But what about the quality?

If the thought of Video Conferencing conjures up images of blurred visuals, disjointed audio, poor connections and massive delays, think again. The quality of VC technology has come a long way in recent years. High definition video conferencing was launched in 2005 and has changed the face of video, offering a far superior quality of experience. The sophistication of the technology is so advanced that it replicates human interaction, empowering your team to collaborate naturally and freely. So you’ll be sitting in your office in London experiencing life-like interaction with your colleague in New York. This is true telepresence!


Video Conferencing does not just deliver a more productive work environment but also a more flexible one. You no longer need to leave the comfort of your home in order to go for that training session in Hong Kong. Remote workers out in the field can have regular catch up meetings as if they were back in the office. Here’s a pretty good video to illustrate my point: http://www.youtube.com/watch?v=DilfZFGqnDs.


Furthermore, with multi-point solutions you can transact with three or more users from remote points as naturally as if everyone were right there in the same room. The world seems like such a small place once you start doing business in this way!


Upon reflection it seems that Video Conferencing is no longer a poor and unreliable alternative to wasteful travelling but a preferable approach!


If you’re considering adopting a greener business model, why not try LifeSize Video Communications. LifeSize introduced high definition to the market and have been the leaders in this space, delivering unrivalled price:performance.

We Love Jack – The IT Guy :) | WAN Acceleration with Riverbed


This blog is dedicated to Jack – the animated face(hero?) of Riverbed WAN Optimisation Technology. Jack has a way of simplifying complex technical issues, such as the bandwidth vs latency debate, so that even the least technically minded person in the workplace will appreciate the benefits of WAN Optimisation.

He certainly makes our job at Layer47 easier, bonus!

Let’s look at a common scenario and a snapshot of a modern enterprise. You have workers and offices, out and about, all over the place and the WAN network is bound to experience considerable data congestion as a result. When an organisation’s Wide Area Network is running slow, file transfers can take forever, office and remote workers get frustrated and project deadlines are missed. Furthermore the Network Manager most often takes the brunt of co-workers complaints and moans regarding sluggish access.

So what is the solution? A common misconception is that increasing your bandwidth will make applications and the network in general run faster. ‘Bigger pipes are always better’ as some would say. But that isn’t always the case, adding more bandwidth does not necessarily improve the end performance of an application over the WAN.

You can have lots of bandwidth but still experience slow applications, and why is that I hear you ask? :)

One reason is latency. The performance profile of many applications is defined by the latency of the connection. Adding more bandwidth will help with the concurrency of the connection but will not improve latency.

This is because most protocols have an element of serialization meaning that they require a response to a packet of data before they can send the next one. Each application will be running back and forth getting bits of information. Combine the number of round trips that some ultra “chatty Applications” such as CIFS make, with high latency between remote offices and you can have a problem on your hands, regardless of available bandwidth.

So if you, like Jack, have got issues like bandwidth limitation, poor TCP performance and application protocol chattiness, what are you going to do about it?

Riverbed WAN Acceleration Technology to the rescue!
A WAN accelerator can help to overcome the pesky effects of latency by reducing the amount of data transmitted over the network using low level compression and caching.

It is a great solution for organisations that wish to:
- Accelerate end user experience over the WAN
- Optimise WAN bandwidth utilisation
- Enable IT consolidation
- Accelerate backup, recovery and replication
- Accelerate mobile workers
- Improve productivity whilst cutting IT costs


However if all this is too much of a technical overload, why not check out Jack’s much more simplified explanation here:
