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.

ManageEngine’s Netflow Analyzer supports performance monitor and mediatrace

June 7, 2012 at 12:00 pm PST

Early this year, ManageEngine successfully completed their second interoperability verification and testing (IVT) with medianet for its product NetFlow Analyzer  through the medianet systems management Cisco Developer Network  (CDN) program.

ManageEngine successfully completed the medianet IVT  for NetFlow Analyzer in February 2012. NefFlow Analyzer supports the medianet features performance monitor and mediatrace.

NetFlow Analyzer leverages flow technologies to generate real-time traffic reports that help in getting visibility into the traffic patterns in the network. It provides:

  • On-demand mediatrace poll for instant monitoring
  • Threshold based alerts for key metrics
  • Highly granular reports with extensive storage options

Medianet at Cisco Live 2012 San Diego

Next week will be a busy week for the medianet team! The team will be at Cisco Live 2012 in San Diego, Infocomm in Las Vegas and Cisco Expo in Israel. We will provide attendees with plenty of updates on the latest medianet technologies in Cisco Video &Collaboration Portfolio, and Cisco Routing & Switching Portfolio.

The team will be introducing the Medianet Media Awareness capability. Media Awareness is a collection of techniques to detect different types of endpoints, media and application types in order to deliver the optimal experience. Cisco switches and routers will be introducing the new Media Services Proxy and Flow Metadata features. Webex and Cisco Jabber will be introducing the new medianet-enabled client to enhance collaboration experience. This new “smart” client embedded with the Media Services Interface, works in conjunction with the “smart” network for optimal Quality of Experience, improved network visibility, quality assurance & quick problem isolation. If you are heading to San Diego, Las Vegas or Tel Aviv, stop by for a chat with Cisco technology experts on your video and network implementations.

Got Video? 5 Tips to Help You Create Compelling Video

In February 2012 179 million U.S. Internet users watched nearly 38 billion online videos, according to industry research.  Predictably, YouTube statistics are colored with consumer viewing behavior. But B2B online video viewing grew 27% from 2010 to 2011 and eMarketer estimates that B2B spending on online video will rise as much as 55% this year. Which makes it the fastest growing ad format in 2012. In fact, your B2B audience expects you to engage them via video. Companies that don’t utilize video as part of their marketing efforts are likely to use lead generation opportunities to competitors that do.

Having online video in your mix is a priority for marketing in the coming year. Here five tips to help  you create compelling videos to drive your business:

 Content is all around you – You already posses a wealth of content that can be reused, recycled and repurposed into online video. It’s tucked into the deep recesses and dank corners of your business. White papers, promotional materials, training videos, presentations developed for product briefings, keynote presentations given by your executive teams at conferences, panel discussions, interviews – the list is endless if you really look. Identify it, categorize it, and leverage it to engage your customers and prospect.
