Today, we commonly see IT budget reduction, cost cutting, and barriers for potential network circuit upgrades. In this tough economic situation, the motive of a network administrator should be optimizing the current infrastructure for future accommodations.
Optimization plays a major role when it comes to distributed network architecture and when users are around the globe.
How can we optimize the network with the current infrastructure without adding a hardware or software to the network? We’ll discuss this below.
The network administrator’s role is to ensure that the network is always up and running, and that the performance of the entire network is always running smoothly, even when …
Network administrators around the globe are very concerned about the type of traffic that is exiting their network. They want their critical business application over the WAN to perform at its best. Non-critical applications like web traffic and social media downgrade the performance of WAN links. Therefore, administrators should avoid non-business applications on WAN links.
Over the last decade, administrators around the globe have used traditional NetFlow and other similar flow technologies to identify the type of traffic on their network. The traditional flow-based traffic analysis is utilized to identify layer 3 application traffic based on port and protocol.
What if a user on the netwo…
Until 2012, NetFlow Analyzer’s Enterprise edition benefited ISPs, MSPs and large organizations that had distributed network architecture, in monitoring their bandwidth.
Any organization with less than 600 interfaces and want to monitor all of them by installing product on Head Quarters data center can go with Professional and Professional Plus Edition which has integrated collectors and reporting engine which collects the data and generate reports.
The Enterprise edition was majorly used by organizations that had a distributed architecture and monitoring was done by means of Central server and multiple collectors across different sites in the same network.
Limitation of Enterprise Edition:…
Cisco Performance Monitor helps you to identify performance issues on the network, Now a days Video is every where and when it comes to corporate network, it has to be treated in such a way that it is with high quality as expected.
An organization considering implementation of Video conferencing or any video streaming should also consider that this will increase significant load on the network. The network should be capable enough to handle this additional load along with existing load.
NetFlow Analyzer with its value added features like Cisco IP SLA VO and Cisco Medianet and Mediatrace helps to implement video traffic on the network effectively.
Network Load Testing using Cisco IP SLA VO :-
Video packets (RT…
Medianet is a framework to simplify video and the operation of networks where video is running. One of the common ways to determine video behavior on a network is to simply look at devices and try to determine the content. Given Medianet’s architecture, they leverage the endpoint itself to understand video traffic, said Grivaud.
They are able to gather this information thanks to an application stack called MSI that sits on the endpoint itself. MSI’s job is to provide simplified autoconfiguration with the netwo…
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:
Video On Demand
Video traffic has very high and extremely variable packets rate with a much higher average maximum transmission unit (MTU) when comparing to Voice.
For classifying the Video traffic to appropriat…
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…
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…
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:
Performance Monitoring (for Video).
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.
1. The Device should run Cisco IOS which supports Cisco Performance Monitor
IOS version :- 12.4(13r)T or above
