What do WebEx QoS and Phone Troubleshooting have in Common?
If you read my previous blog then you’ll already know that the answer is Medianet. In Part 1 of this 2 Part blog series I discussed the new reverse Metadata capability, provided by a Cisco network, that allows an Enterprise to enable granular QoS marking for all the different media streams that make up a WebEx meeting. In this 2nd instalment, we’re going to take a look at how we can extend Medianet’s Mediatrace capability to Cisco’s 79XX, 89XX and 99XX IP Phone portfolio.
The other recent innovation for Medianet is Prime Collaboration’s ability to now invoke a Mediatrace for a number of IP Phones models that don’t support the MSI (Media Services Interface). As these devices cannot originate Metadata, it has been previously impossible start a Mediatrace through end point selection for telephones in Prime Collaboration. It is now possible, reactively and proactively, to troubleshoot voice quality issues on 79XX, 89XX and 99XX devices, using the same combination of Medianet and Prime Collaboration tools that have previously only been applicable to personal and room based video systems. Take a look at one of my previous blogs, “Medianet in Action”, for some additional background material on video troubleshooting. The demonstration below shows how to start a Mediatrace for a pair of phones.
The video collaboration world has reached another interesting inflection point. The market has shown that there is an experience threshold to deliver effective remote video collaboration – recall the rapid doubling of the video market between 2006 and 2008 when HD video became possible across a range of platforms. It is also clear that high quality experience delivers both dramatic productivity increases as well as significant business growth opportunities. So what is holding back the market currently?
The challenge has been to deliver the threshold experience at a price point that is accessible to everyone. The solutions that are being offered up until now have either been too expensive to roll out at scale or have compromised on quality, security, connectivity and interoperability to the point where the experience threshold is not achieved. The market has shown that “good enough” does not deliver the type of user experiences that businesses need.
We have been talking about quality attributes for some time, and arguably Cisco has been progressively improving this with both software and hardware developments. However, the latest endpoints announcements from Cisco at Enterprise Connect address perhaps the most fundamental requirement to drive the video collaboration market:
Delivering business video for everyone
Video collaboration has delivered many benefits to the organizations that are taking advantage of it today. By embracing this technology these organizations are seeing greater productivity among their employees, partners and vendors as well as reduction in travel costs by using video to be anywhere at any time.

What do WebEx QoS and Phone Troubleshooting have in Common?
The answer is Medianet, which in conjunction with a Cisco network can provide an innovative solution for two very different real life problems. In Part 1 of this 2 Part blog we’re going to discuss how customers can use Medianet Metadata to provide a robust QoS mechanism for the WebEx cloud service within their Enterprise Networks. Keep an eye out for Part 2 where we’re going to take a look at how we can extend Medianet’s Mediatrace capability to Cisco’s 79XX, 89XX and 99XX IP Phone portfolio. I’ll also point out the benefits for each of these completely different Medianet use cases.
WebEx is a SaaS Conferencing service providing web based data, audio and video conferencing for millions of users. As it’s a cloud service, it’s inherently secure and in a lot of use cases it will tunnel all its media streams within HTTPS. That’s great for secure transport, but it’s resultantly challenging to map the constituent parts of the WebEx application into a granular Enterprise QoS policy. Why would we want to do that anyway? Isn’t it good enough to mark all the WebEx traffic the same? As the saying goes, there is a method to our madness.The tunnelled WebEx traffic contains control packets, data-sharing traffic and possibly VoIP, which are relatively low bandwidth media streams. On the flip side any tunnelled video traffic will likely be bandwidth hungry by nature. The challenge we want to circumvent is how to ensure the WebEx video traffic does not “swamp” the other types of meeting traffic. Ultimately, we want to allow end users to enable the video service they have paid for, without the risk of video having a negative impact on the overall quality of the online conference. We do everything with the end user in mind to make sure you have the best possible experience.
For those of you that don’t know, a WebEx client can generate Medianet Metadata. In simple terms, Metadata is a way for a Cisco application to announce itself to a Cisco network. In the case of WebEx, different Metadata packets are transmitted onto the network, uniquely identifying all the component media streams (including video) that comprise a WebEx conference. This allows a Cisco network to useWebEx Metadata to differentiate between any WebEx traffic types, even when securely tunnelled over a HTTPS connection. The figure below provides an illustration of the different Metadata packets that will be generated for different types of WebEx traffic.

This recognition is a rewarding validation for the no-compromise, design led approach we undertook when developing our newest video solutions. And just as important as the awards is the feedback I’ve received from the people who use our technology.
You let us know that you appreciate the attention to detail and unparalleled user experience. And our focus on harmonizing the technology with the human aspect of face-to-face communications. By combining Scandinavian minimalism with Californian approachability, I believe we’ve succeeded in letting the technology recede and emphasizing the connections between people. It’s about allowing people to connect with one another, anywhere, in a powerful way without distraction – from the browser to the boardroom.

Wall Street Journal writer Sue Shellenbarger makes some great points in her recent article “Surviving the Conference Call.” She points out many of the downsides of not collaborating in person — people multitasking during calls, bad audio, the inability to build rapport.
I remember those days well. For me, they’re in the past because I use video on nearly every call I make, whether it’s a group conference call or a 1:1 conversation with a co-worker.
Shellenbarger reports that about 65% of all conferencing is still done via audio calls, according to Wainhouse Research. To some, video may seem like the future, but it’s really available and affordable here and now. It’s moving from an executive-only tool to something available to everyone.
At first I was surprised that Wainhouse predicts time spent in audio conferences in the U.S. will continue to grow 9.6% a year through 2017. But in context, it’s pretty slow growth compared to predictions for video conferencing (check out Figure 14).
True, video is a new concept for many of us. Just the idea of being heard and seen is a hurdle for some people. I used to hide from cameras at parties and now I use one throughout the day. The benefits quickly outweighed any awkwardness. I found right away that the ability to have eye contact with people and see their physical reactions during a conversation makes a significant difference in the communication. Read More »
