Spirent Communications, a supplier of network test and measurement solutions, announced that it supported New H3C in conducting what is believed to be the highest density 100 Gbit/s data centre switch test.
Spirent also announced it had partnered with the China Mobile Research Institute (CMRI) to demonstrate automated testing of virtual core networks.
100 Gbit/s switch testing
The test, completed by Spirent and the New H3C Group and moderated by independent test lab Network Test, demonstrated the line-rate forwarding capacity and hyper-scale IP route announcement capacity of the H3C S12500X-AF chassis loaded with 100 Gbit/s ports and achieving a density of 768 x 100G ports per chassis. The S12500X-AF switch can support 48 x 100 Gbit/s QSFP28 pluggable optical modules per slot.
The test involved Spirent TestCenter and the N11U chassis, representing Spirent's flagship network performance test solution, equipped with the high density dX3 12-port 100 Gbit/s test modules designed to verify next-generation data centre architectures and routers.
For the testing, Spirent TestCenter generated 100 Gbit/s line-rate transaction traffic of various frame lengths and provided packet loss, latency, jitter, frame sequence, code errors and FCS error analytics to reflect the quality of transmission in real time.
The Spirent dX3 quint-speed test module can support twelve 100 or 40 Gbit/s ports per slot, 25 x 50 Gbit/s ports, or 48 x 25/10 Gbit/s ports per slot. It also supports key interface features such as FEC, auto-negotiation and Link Training. The module can be used to verify data plane QoS for hyper-dense network devices at line-rate, and for testing complex routing, data centre and access protocols on switches and routers.
Virtual core network testing
Separately Spirent announced a collaboration with the China Mobile Research Institute (CMRI) to demonstrate automated testing of virtual core networks at Mobile World Congress (MWC) Shanghai. Spirent noted that the demonstration is part of a joint effort to develop a methodology for automated testing of the functionality and performance of the China Mobile TIC (Telecom Infrastructure Cloud).The partners plans to incorporate the test methodology into an automated testing system developed by CMRI to speed testing of services in operational virtual core networks and to form part of the complete vEPC environment developed by CMRI.
At MWC, Spirent has provided the test engines for the demonstration, including the virtualised mobile core network emulation and performance testing tool, Landslide Virtual, and the automated testing platform, iTest. The solutions automate performance and functionality tests used to develop, spin-up and monitor the vEPC. In addition, devops models have been developed for the test methodologies, allowing tests to be automated and incorporated into the virtualised network.
