Validating ADVA's Virtual Switch

EANTC's introduction and test cases
The goal of the EANTC team's evaluation was to test the performance and scalability of the Ensemble Connector platform, a customer premises equipment (CPE) virtual switch coupled with an Intel® Atom™-based virtualization (NFV) platform.

Ensemble Connector is ADVA's proprietary virtual switch (vSwitch) implementation: As our tests showed, ADVA has successfully developed its vSwitch so that its performance is some way better than the standard implementation of the Open vSwitch with Data Plane Development Kit (DPDK) library (OVS-DPDK).

Our tests focused on a comparison of the forwarding performance of the two virtual switches, which were running on the same COTS server.

All tests were performed with a series of standard packet sizes ranging from 64 to 1518 octets, as well as a mix of packet sizes realistically resembling typical Internet traffic (IMIX). The IMIX we used in the test is defined as a proportional mix of several frame sizes, as specified in the following table:

In addition to raw throughput performance we also measured the latency, an important factor to include when evaluating the performance of any service.

Further, we analyzed the scalability of the solution by running performance tests with a different number of simulated MAC addresses.

Finally, we verified the functional aspects of the solution -- the support for link aggregation and VLAN tagging.

EANTC partnered with Intel to implement test methodologies for benchmarking data plane performance on Intel architecture-based platforms that include key open source ingredients, including DPDK and OpenStack.
