The Metaswitch Perimeta was one of the first session border controllers architected as a pure software solution and designed for operation in any cloud or virtualisation environment. Perimeta has unique media and signalling separation and can scale granularly to meet new demands. The solution features a secure distribution engine (SDE) for load balancing and distributed admission control (DAM) to make massively scalable deployments easier.

• Protection from misuse of services (DoS/DDoS attacks)

• Hides network topologies

• Media pinholing – target media guidance and control

• Transcoding
