Spirent TestCenter used for asymmetric throughput, latency routing testing on 140 ports
Spirent Communications, a leader in network testing, announced today that Casa Systems, a worldwide leader in next generation cable edge technology, has selected Spirent TestCenter to test its Cable Modem Termination System (CMTS) and Integrated Converged Cable Access PlatformCCAPsolutions. Spirent TestCenter was used to validate routing performance, asymmetric throughput, latency and packet loss of Casa Systems' C10G and C3200 platforms.
The manifold increase in both over-the-top (OTT) IP and MPEG video traffic, driven by popular applications such as Netflix, YouTube, Hulu, and services such as unicast VoD, and DVR are stressing today's CMTSs. More than ever, it is critical to verify the ability of these systems to handle tens of thousands of cable modem subscribers and unprecedented level of Layer 2-7 traffic. Casa Systems chose Spirent TestCenter because of Spirent's extensive experience in building high scale test beds, high per port protocol scale and intuitive user interface for easily configuring large tests.
"We needed to verify throughput and performance of our CMTS and CCAP solutions," said Nanying Yin, Vice President of Technology at Casa Systems. "We chose Spirent for our mission critical testing because they have a proven ability in scalability testing of data traffic in the data plane and protocol signaling in control planes that emulate real deployment environments."
The Spirent test bed consisted of 120 1G and 10 10G test ports. This test setup was used to perform packet loss, latency and asymmetric throughput testing of the Casa CMTS system using built-in test wizards. The asymmetric throughput testing is necessary to accurately validate a CMTS by subjecting it to realistic bi-directional traffic. In addition, access, routing and MPLS protocols were also validated on the Casa CMTS system.
"Our work with Casa Systems is the latest example of how we are continuing to develop the most advanced hardware and software solutions in the test and measurement space," said Rajesh Rajamani, Senior Product Marketing Manager at Spirent. "When it comes to testing the next-gen cable access systems, it is vital to ensure that video frames of MSO clients are not dropped unfairly and streaming services without interruption."
