Fast and Flexible- Accelerated P4C and Open vSwitch Datapaths for OpenStack
Channel: OpenInfra Foundation
Date: 2016-10-25

Virtual switches are typically deployed in OpenStack managed cloud datacenter servers to act as overlay on/off-ramps, implement micro-segmentation (security groups) or otherwise process and forward packets. These virtual switches can implement the behavior required by an existing standard (for example Open vSwitch implements OpenFlow compliant switching), or implement the semantics directly expressed using a program (potentially written in a domain specific language like P4).
