Session Border Controllers

With the advent of VoIP came a host of network opportunities and challenges. One such challenge related to NAT (Network Address Translation) as the borders between networks, private and public or inter‐carrier were traversed. Various network devices and techniques evolved to solve these NAT traversal issues; one however, took the lead and now has become ubiquitous, offering a variety of functions – the Session Border Controller or SBC. Demand for SBCs remains strong and continues to grow within the service provider and enterprise markets which combined represent a global market worth in excess of $1.6 billion over the next 4 years (Infonetics Research).

A Session Border Controller does exactly what is says; Controls the data streams and sessions (in the VoIP case sessions represent calls) as they traverse the border or interconnection point between two networks. The border point of control can be in the enterprise e.g. where a corporate network enters the public Internet or at an interconnect between two service providers. In either case the SBC provides a variety of functions for its host network.

Securing and connecting the network – Network Address Translation (NAT) is performed and firewall functions may be implemented in conjunction with other firewall devices. VoIP signaling is enabled and corrected as necessary. The border is policed and protected from potential Denial of Service or other attacks. Ultimately the SBC says who gets in and who doesn’t.
Quality of service – An SBC can act as a load sensing and balancing router and becomes a key component of the network’s QoS policy.
Management &Statistics – As all network traffic must flow through an SBC it’s a great place to collect statistics, billing and other management information.
Regulatory compliance – SBCs must allow for lawful interception and monitoring of calls and have the ability to prioritize emergency calls.

Flexibility, connectivity and performance are all required for the ideal Session Border Control platform. The Advantech product line provides all these elements. Long term experience and relationships with the major processor and NPU vendors ensure that Advantech offerings always provide for the latest technology and can demonstrate clear upgrade paths. The FWA-3210 is an excellent example of an OEM application ready platform. Available with up to 8 Gigabit Ethernet ports and considerable expansion options along with a choice of the latest Intel® embedded and commercial processors the FWA-3210 is ideally geared towards the needs of the SBC OEM. The FWA-6510 based on dual Intel® Xeon® E5-2600 processors with up to 8 cores positions it well for more demanding performance and 10GbE connectivity..
