The perimeter of a communications network is only as strong as its weakest link. Beyond the boundary of a managed infrastructure lie many threats to service continuity and to the integrity of the network.
As fixed-line and mobile network operators transition their voice services to cloud-based all-IP infrastructures, internetworking and security devices in the access and interconnect layers must evolve. With VoLTE deployments intensifying, and with the rising number of client endpoints featuring innovative HD voice codecs, video chat capabilities, presence and instant messaging, network operators will demand increased capacity and flexibility from their SBC at dramatically lower cost per-session. Moreover, with the continued adoption of SIP as an enabler for RCS and even IoT endpoints, there will no longer be a predictable correlation between signaling and media transport or practical ways to architect for the increasingly arbitrary swings in traffic patterns. This significantly complicates the dimensioning of classic SBC appliances and dramatically increases costs and the amount of stranded capacity.
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 signaling 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.
In numerous independent tests, Perimeta has been proven to provide superior protection from any number of malicious strikes against core communications service delivery platforms, including Distributed Denial of Service (DDoS), fuzzing or malformed packet attacks, while continuing to process legitimate traffic at wirespeeds. Perimeta provides additional security elements including encryption and authentication, and sophisticated functions such as dynamic blacklisting. Furthermore, whether performing the role of fixed-line VoIP access security or VoLTE roaming and interconnect, Perimeta supports comprehensive real-time analytics, enabling network operators to quickly identify and resolve issues while continually measuring service operation against important key performance indicators (KPIs).
We were genuinely surprised at how quickly were were able to deploy the platform and provision the first live subscribers. We are looking forward to expanding our relationship with Metaswitch in the future.
