If You Build It, Will They Come?

So after reading my last blog, you’ve finally come to the realization that you now need to start getting serious about creating video for your organization as the return on investment is certainly a compelling one. But where do you start?  Do you immediately run out and begin building a studio and streaming infrastructure?  Probably not.  Even though the ROI on video is overwhelmingly positive, Read More »

Video: Why Aren’t You Using it?

From Shirley Temple pulling Americans through the Great Depression to 2001: A Space Odyssey inspiring The Information Age to Star Wars giving us our next generation of scientists, astronauts, and futuristic technologies, video has always had the power to motivate and inspire us, now only imagine what it can do for your business.

Implementing video as a tool to transform and accelerate your business always needs an ROI and some pretty convincing numbers in order Read More »

What do WebEx QoS and Phone Troubleshooting Have in Common? Part 2

April 25, 2014 at 12:07 pm PST

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.

What do WebEx QoS and Phone Troubleshooting Have in Common? Part 1

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.

MegaTrends: New Video Services and Their Potential Impact on Your Network – Part 2

In the first part we discussed how video services are evolving within enterprise networks. Content may be sourced from internal servers, BYOD end points or external content providers, thereby creating a mix of managed and unmanaged services. This has led not only to growth in traffic, but also a competition for actual resources between the different types of services.

We have discussed how these services are evolving, now moving to a per application, per session model which ensures that specific resources are allocated depending on the nature of the usage. Tools such as those provided by the medianet architecture, combined with changes in defaulting all traffic within the VPN session back to the corporate network, contribute to this evolution in session management.

Once again, we turn to Thomas Kernen to provide some insight into how recent technology improvements are designed to help with managing video traffic growth and enabling better content distribution models.
