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.

We don’t just explore new markets. . . we win them.

Jack Welch famously said, “When you’re number four or five in a market, when number one sneezes, you get pneumonia. When you’re number one, you control your destiny.

Well we’re the big boy in the toddler room, and we’re passing around the germs.  The market is the digital signage market — small and young, yes, but with enormous potential.  As in more than $1.1 billion last year and growing at a 13.3% CAGR.

Frost and Sullivan recently published their highly-anticipated annual “Global Digital Signage Systems Market“, and it pegs Cisco at number one in the market with 14.2% of the market.   And this excludes displays used for corporate communication applications.  Here are a few more delectable tidbits:

Is Video Training Better Than Being There?

Videocast featuring  Dr. Susan Holliday, Executive Director, Technology & Information Services, Capistrano Unified School District.

  Is Video Training Better Than Being There?

  Date: June 19, 2012

  Time: 10:00 am – 11:00 am Pacific

  Register Now

 

 

Enterprise video content solutions help you use video in new ways, from organizational communications to training and live events. In particular, training is an ideal use case for video—participants in a live training can go back and review the material at a time and place that’s convenient for them.

 Join Cisco and Dr. Susan Holliday, Executive Director, Technology & Information Services, Capistrano Unified School District, for a videocast on June 19, 2012, 10:00 am Pacific, to hear how they are using video for professional development. Serving 53,000 students in grades pre-K–12, Capistrano Unified School District (Capistrano USD) has 56 campuses spread over 195 square miles in Orange County, California.

Dr. Holliday will cover how the district first put the Cisco video content solution to work capturing and sharing professional development sessions on defining effective instruction and student engagement, for district principals and their site leadership teams.
