Announcing the MSP CDN Program Including the IVT Program, Plugfest!

One of the key objectives of Medianet is to integrate a smarter network with various media endpoints in order to simplify end-to-end deployments and operations and to enhance quality of experience for the end user. We are very happy to announce Plugfest as a strategic step forward towards meeting this objective. Plugfest is an Interoperability Verification Testing (IVT) event to be hosted at the ASIS show (booth 213) in Philadelphia, September 10- 12, 2012. Plugfest at the ASIS will be focused on verifying IP Surveillance Cameras within a Cisco network.

We are very pleased to announce Plugfest for you. Plugfest launches the Media Services Proxy (MSP) capability as part of Cisco Medianet solutions. This would be a very good opportunity for you to get your cameras verified with the Cisco’s Medianet-enabled network by just plugging your camera in. There is no additional development or change required on the end points provided there is compliance to standard based protocols like RTSP, SDP and mDNS, which MSP is based on. On successful verification, your organization along with qualified camera models and the capabilities they have been tested against would be listed on the CDN (Cisco Developer Network) partner page. You would also get the Cisco CDN “Compatible” logo that can be shared externally! You can find all details on Plugfest on the CDN MSP portal. Read More »

Soneco’s ICmyNet.Media completes IVT with Medianet

August 14, 2012 at 3:24 pm PST

A few weeks ago, Soneco successfully completed their interoperability verification and testing (IVT) with medianet  for its product ICmyNet.Media through the medianet systems management Cisco Developer Network  (CDN) program.

By working very closely with the medianet team through CDN, the ICmyNet.Media team added support to performance monitor enabling our customers to gain visibility into the network, to learn more about the performance of their media flows and to perform faster troubleshooting.

ICmyNet.Media is web based network monitoring tool that leverages medianet performance monitor and gives you valuable insight in your network media flows. It allows you to: Read More »

A new Application recognition paradigm – Flow metadata (Part 2)

In the first part of this blog we discussed how Flow Metadata addresses encrypted/obfuscated traffic, multi-stream interactions, ensures end-to-end  consistent policies and enables fine-grained policies. In this part of the blog, we discuss additional deployment scenarios making network classification a real challenge and how metadata addresses them.

A new Application recognition paradigm – Flow metadata (Part 1)

Flow metadata allows an application to explicitly signal any arbitrary attributes to the network from node to node. This avoids the pitfall of data not being visible for deep packet inspection due to increasing use of encryption and obfuscation.

Tradition network classification solution using deep packet inspection technology is localized as classification may not be available along the path. How can network element enforce policies if they do not have uniform view of traffic to apply consistent enforcement of network policies ? Flow Metadata is reusable across network nodes by allowing sharing of flow attributes amongst network nodes. This allows appropriate and consistent policies to be applied at each hop, end to end, improving the quality of experience.

The flow metadata component of medianet allows the application to convey information to a set of network nodes. This makes it easy for management software to report information in a more meaningful way.  For example, “John from finance is having quality issues with his Jabber desktop video” is much easier to diagnose than obscure IP addresses and protocol numbers. Imagine  extending  this meaningful application context information to network policies such as QoS, routing, and  SLAs.  The medianet flow metadata feature enables granular policies based on application context and not limited to network attributes. For example, with flow metadata, it is now possible to easily prioritize scheduled sessions over ad hoc sessions.

Announcing Media Services Proxy

Medianet Media Awareness enables the network to become application and rich-media  context aware end to end. Media Services Proxy is one of the techniques to detect different types of endpoints, media and application types (Telepresence, video surveillance, desktop collaboration and streaming media) in order to deliver the best experience.

Media Services Proxy Components

Media Services Proxy

Identification

Media Services Proxy, an IOS technology, uses light weight deep packet inspection techniques to snoop standard based signaling protocols. It uses a variety of standard signaling protocols (SDP, H.323, H.245, RTSP, mDNS, etc.) to learn about the characteristics of endpoints and applications from legacy systems.

Proxy Services

Once the endpoints and application types are known, MSP can apply a number of services on behalf of the endpoints and flows. For example, MSP detects a video surveillance camera, it  applies Auto Smartports by automatically configuring the switch port for a camera to significantly simplify deployment. When MSP detects the flow type, it can apply QoS or bandwidth reservation on behalf of the flow. More importantly, MSP can share flow attributes amongst network nodes thereby allowing  policies to be applied end to end.

Where to find Media Services Proxy today

Media Services Proxy is best positioned at user edge (e.g. access switch) and resources edge (e.g. internet edge). MSP is first introduced in IOS 03.03.00.SG.151-1.SG on Cisco Catalyst 4000 series switches and in IOS 15.2(3)T on ISR-G2 routers. Over time, more products will be implementing Media Services Proxy.
