Policing Live video traffic and monitoring using NetFlow Analyzer

0

I hope everyone who had attended our joint webinar with Cisco about QoS Design and validation, would have got a better idea on how to design a network with effective QoS policing. For those who missed the Webinar, you can find the video presentation here.

In continuation to our Webinar, this blogs helps you in setting up QoS policies for Live Video Traffic and monitor them using NetFlow Analyzer.

On a network the Video traffic spread in three format:

  1. Video Conferencing

  2. Video On Demand

  3. Video Broadcast

Video traffic has very high and extremely variable packets rate with a much higher average maximum transmission unit (MTU) when comparing to Voice.

QoS Treatment:-

For classifying the Video traffic to appropriat…

Live Video Traffic Monitoring in NetFlow Analyzer with Minimal effort

Now! NetFlow Analyzer 9.6 got released. So the question would be, what’s new in it?. Click here to get answer for this. This blog is about a more exciting and valuable feature for Networkers, as it saves time spend on report generation.

Yes, this is about On Demand Mediatrace reporting which I have already talked about in my earlier blog. Instant report generation available for Performance Analysis of Media rich traffic.

Cisco Mediatrace monitoring allows you as a network admin, to analyze the performance of real time traffic session on each hop. With this On Demand Mediatrace monitoring, Network Admin has visibility of current sessions going on the Network device and he can choose the session for whic…

Analyzing Live Video Performance using NetFlow Analyzer

1

With highly advanced technology development, the overhead on Network Administrators in ensuring prompt delivery of business critical applications over the WAN is very high. Video conferencing is predominantly taking place in major organizations for a variety of reasons like less cost, more productivity and a whole lot of advantages it can offer.

Video conferencing will take place between different branch locations within the same country or over the WAN between different countries. A Network Administrator needs to ensure smooth conferencing of video and avoid undesirable factors such as delay, packet loss and jitter, which are most likely to hamper the quality of the video.

In general, the Network A…

Cisco Mediatrace Reports in NetFlow Analyzer

After configuring the Initiating Router and Responders for Mediatrace monitoring, as the next step we would now get into report generation. The data is represented in the form of easy to understand charts and graphs. The reports can be generated individually for each session.


Cisco Mediatrace Reports:-

The reports are generated based on the metrics each session is associated with. The metrics are:

  1. System-Data monitor

  2. Performance Monitoring (for Video).

System-Data Monitoring:-

If the option selected is System-Data monitoring while creating session, the metrics for which reports generated are :

  • System Metrics: INTF Profile

  • System Metrics: CPU Profile

  • System Metrics: MEMORY Profile

With Cisco Medianet, you can measure the performance of voice traffic on a router which are configured for Medianet NetFlow export. The performance of real time traffic could deteriorate during its travel across different devices on the path.

NetFlow Analyzer with its Cisco Mediatrace monitoring allows you as a network admin, to analyze the performance of real time traffic session on each hop & this post is about Cisco Mediatrace configuration in NetFlow Analyzer.


Prerequisite:-

     1. The Device should run Cisco IOS which supports Cisco Performance Monitor

           IOS version :- 12.4(13r)T or above

Cisco Medianet Reports in NetFlow Analyzer

1

After configuring Cisco devices for Medianet exports(as mentioned in the previous blog), the next step is generating Medianet reports in NetFlow Analyzer. The Medianet report in NetFlow Analyzer shows traffic IN and traffic OUT details based on media volume, round trip time, packet loss and jitter.

The user can also generate report for each of these metrics separately. To generate report for Medianet, Drill down to each interface of the router in NetFlow Analyzer for which Medianet export is configured, then you can click on Medianet Tab to generate report based on the desired parameter.

Cisco Medianet Reports in NetFlow Analyzer:

The Medianet Reports can be generated for Source, Destination and Applic…

Cisco Medianet (Performance Monitor ) Configuration

In continuation to Cisco Medianet Introduction blog, This blog explains the configuration of Cisco routers to export Medianet related information .  In the latest IOS version, Cisco adds Performance Monitor parameter to its NetFlow export. So, with NetFlow traffic analysis, we gain bandwidth monitoring and performance monitor of business critical application.

Cisco Performance Monitor:-

The performance impact on business critical application on the network is due to the following parameters jitter, latency, packet loss,  low RTT. The Cisco Performance Monitor will help to monitor Jitter, Latency, Packet Loss and RTT for each flow packets exported from the router.

Performance Monit…

Traffic consists of various forms. Voice, video, data etc. When you employ a tool to monitor traffic, you should ensure all these sub-types are taken care of. We are glad to offer you video traffic monitoring for free through the Cisco Medianet monitoring feature.

Off late, IT firms prefer Teleconferencing or Video Conferencing to facilitate business communication.  This saves a lot of time & resources in terms of money, commute etc. There is a complete transition from boardrooms to virtual boardrooms. It is an era of ‘virtualization’. It doesn’t matter where who is. Whether it is the next cubicle, next room, next block, next building, next city, next country, next continent, it is a global …
