Lets get started… Read More IxNetwork : Using IxNetwork NextGEN Framework Configuring OSPF- Blog3
In my previous blog I have explained the process to add Ixia chassis and ports to the IxNetwork application. Please check my previous blog here In this blog I am going to configure IP connectivity between DUT and the Ixia chassis. Step 1 : When you open IxNetwork application you would see following screen. You… Read More IxNetwork : Using IxNetwork NextGEN Framework Blog-2
Ixia is a big player in network traffic generator platforms market. Almost all the vendor use Ixia extensively to test and replicate customer scenario on their equipment. It has many variants and I am planning to discuss few major variants like IxNetwork, IxExplorer, IxLoad in my upcoming blogs. In this blog I will be talking… Read More IxNetwork : Using IxNetwork NextGEN Framework.
You might have seen issues like choppy voice, unclear deferred video etc in your network.

So, we have seen how to identify the microbursts in the network. Once you identify the microbursts you tend… Read More Wireshark : How to identify Top-talkers in Network.
We come across this situation a lot when we see drops in QOS classes and continuous increase in “Total Output drops” on interfaces but for sure our traffic never crosses CIR rate which ISP provides. This quizzes mostly every network engineer many times in their career. You would see something like this: Router#show interface ten0/0… Read More Wireshark : How to identify burst of traffic in network
Hope you have checked my previous blog on Jperf Please check the above jperf part 1 blog as this one just an extension of the previous blog. In previous blog we have tested Iperf with single data stream(class) where we have assigned 70% bandwidth of the CIR rate to “child1” class. With this configuration we… Read More Using Iperf for Network Bandwidth Measuring/Testing – II
