Metaswitch Perimeta is the first cloud native virtualized session border controller (vSBC) proven to deliver the Session Initiation Protocol (SIP) interworking and security performance demanded of large-scale rich communications services.


As a cloud native virtualized network function (VNF), network operators can deploy Perimeta on classic virtual machines, in lightweight containers or employing a combination of the two.

Perimeta supports any independent VNF lifecycle manager (VNFM), and network operators can deploy Perimeta with any mainstream VNF infrastructure (VNFI) Management and Orchestration (MANO) platform.

Perimeta was designed with a microservices philosophy in mind, allowing network operators to decompose signalling and media functions and deploy them independently, dynamically scaling each function on-demand to meet the real-time requirements of an entire network or an individual, distinct service slice.
