Wind River announced a new performance benchmark for its accelerated virtual switch (vSwitch) integrated within Wind River Carrier Grade Communications Server, which is designed for network functions virtualization (NFV).
Wind River said its accelerated vSwitch can deliver 12 million packets per second to guest virtual machines (VMs) using only two processor cores on an industry-standard server platform, in a real-world use case involving bidirectional traffic. This performance represents 20 times that of the standard Open vSwitch (OVS) software used in typical enterprise data centers. Providing unlimited scalability when instantiated on multiple cores, this industry-leading performance is achieved using up to 33% fewer CPU resources than other commercial solutions, with no requirement for specific hardware acceleration.
“As a key element in our Carrier Grade Communications Server, our accelerated vSwitch was designed from the ground-up to incorporate the Carrier Grade features that are critically important for telecom networks that must deliver six 9s reliability,” said Mike Langlois, general manager of the communications business for Wind River. "For example, the accelerated vSwitch provides fast convergence during live migration of VMs, while minimizing the impact of dirty page updates. To allow for optimum resource allocation, it provides deterministic processing performance without the jitter of over 10% exhibited by the standard Open vSwitch. Finally, protocols such as LAG, VLAN tagging, and VXLAN provide the security features that are essential for telecom networks.”
