S9 Session Border Controller

At the top of its class, GENBAND’s high performance S9^TM Session Border Controller is massively scalable with signaling bandwidth up to 12Gbps, media bandwidth up to 24Gbps, and up to 150,000 concurrent sessions and 1,500 Calls Per Second. It is ideally suited for network operators wanting to avoid “rack-and-stack” SBCs or needing to expand their IP services using a pay-as-you-grow model. The S9 delivers secure carrier class, real-time communications for fixed and mobile operators, enabling new service offerings, rapid revenue generation and network cost-savings. With extensive security, policy enforcement, and session management capabilities, the S9 SBC brings service providers advanced levels of functionality, flexibility, and performance at IP network borders.

Carrier-to-Carrier: The S9 SBC provides secure connectivity with granular controls to proactively manage interconnect quality, capacity, and availability, supporting bilateral and multilateral carrier interconnect agreements for national call routing, international long distance, and local PSTN termination.

Carrier-to-Enterprise Access: Normalizing traffic for seamless connectivity between carrier and enterprise networks, the S9 SBC provides extensive SLA management, SIP trunking, PBX/IP PBX and H.323/SIP interworking, and call center and hosted VoIP application support.

Carrier-to-Consumer Access: The S9 SBC protects the network edge with overload protection via multi-stage rate limiting policies, registration throttling, and subscriber authentication and authorization, enabling service providers to deliver the highly differentiated voice and multimedia services

Security: The S9 SBC protects service provider and enterprise networks by providing multi-layered security against a wide variety of Internet threats meant to disrupt or disable IP networks including flood attacks, DoS/DDoS attacks, and SIP signaling attacks. Capabilities include intelligent access and admission control, private-to-public IP network address and port address translation (NAT and PAT) and NAT traversal, and topology hiding.

Interoperability and Interworking: The S9 SBC normalizes the network edge, providing a wide range of flexible policies to seamlessly interoperate with multi-vendor and multi-protocol VoIP equipment. Normalization includes ANI/DNIS, network address, protocol, DTMF, and codec interworking for smooth interworking between interconnect and access networks. Compatibility across firewalls, application servers, proxies, endpoints, media gateways, and softswitches is ensured with a large community of interoperability partners. Able to separate media and control planes for efficient decoupled networks, the S9 supports 3GPP™, IMS/LTE, NGN, MSF, and PacketCable™ networks.

Advanced Routing Feature Set: The feature set in the S9 SBC provides intelligent routing at interconnect borders, including adaptive, least cost, and percent-based routing as well as dynamic route hunting. It enables state-of-the-art dynamic routing of traffic between interconnect peers based on call completion rates, route profit, and route availability. Sophisticated routing intelligence reduces IP-IP session routing complexity, and policy enforcement enables advanced traffic engineering at the session layer for managed service assurance and SLA compliance. The feature set also facilitates VoIP traffic management by monitoring and maximizing utilization of high-value feature servers, application servers, and media gateways.

Policy Enforcement, SLA Management and Session Visibility: The S9 provides a comprehensive SLA management solution with multi-staged policies to admit, inspect, and shape traffic. It manages network access using real-time and aggregated admission control policies; prevents service theft by authenticating users, inspecting media address, and codec; and shapes traffic per QoS marking. Visibility is provided into each IP session by generating real-time session detail records (SDRs) with over 90 fields.

Hardware: Based on a 14-slot ATCA chassis, the S9 SBC uses a modular single board computer solution that offers carrier-class, symmetric multiprocessing performance with next generation dual processors, in addition to full high-availability (HA) with sub-second failover, hot-swappable components, and in-service platform upgrades.

Decoupled and Integrated Options: With its high transaction, advanced computing architecture, the S9 SBC supports multiple options for handling media and signaling traffic. The integrated option provides for centralized security and control of both media and signaling, whereas the decoupled option enables an efficient network for handling high volumes of signaling traffic in the S9 and media traffic in border gateways.
