Is there a way to simulate packet loss rate on the switch or adapters? Like a tool acting as Linux command “tc”?
In fact, I want to simulate packet loss at end-host to test our new hardware performance in real RDMA environment.
Our NICs are Mellanox ConnectX-5 and switch is Mellanox SN2100.
Could you provide some tips?
Looking forward to your insight :).
Hi Haonan Qiu,
Mellanox provides a Performance Tests (perftest) package for OFED. perftest package is a collection of tests written over uverbs intended for use as a performance micro-benchmark.
The tests may be used for tuning as well as for functional testing.
The perftest package contains a set of bandwidth and latency benchmark such as:
InfiniBand / RoCE

Hi Zhang Yuying.
Thanks for your solution. It’s very helpful.
Sorry for the late update. I have found the tools in the driver and the loss can be simulated in the NS3-RDMA environment.
