Layer-2 Extension (OTV) Use Cases

Test Virtual Appliance Throughput with Spirent Avalanche NEXT

During the Networking Tech Field Day 6 Spirent showed us Avalanche NEXT – another great testing tool that generates up to 10Gbps of perfectly valid application-level traffic that you can push through your network devices to test their performance, stability or impact of feature mix on maximum throughput.

Not surprisingly, as soon as they told us that you could use Avalanche NEXT to replay captured traffic we started getting creative ideas.
