Sonus SBC 5200™ Session Border Controller
The Next Generation of SIP Session Management
The shift to multimedia/multidevice communication requires a new generation of Session Border Controller (SBC): one that looks beyond simple border mediation to a broader world of seamless, service-rich interoperability. The Sonus SBC 5200 is the first SBC that addresses the next-generation needs of SIP communications by delivering embedded media transcoding, robust security and advanced call routing in a high-performance, small form-factor device.
The Sonus SBC 5200 enables service providers and enterprises to quickly and securely enhance their network by implementing new services like SIP trunking, secure Unified Communications and Voice over IP (VoIP). The SBC 5200 provides a reliable, scalable platform for IP interconnect that delivers the longstanding strengths of the Sonus SBC 9000 Session Border Controller—security, session control, bandwidth management, advanced media services and integrated billing/reporting tools—in an SBC appliance. For pure IP-to-IP interconnect, the SBC 5200 delivers a network edge like no other:
- Unique design with embedded transcoding/encryption processing forun beatable real-world performance and scalability
- Advanced policy and routing intelligence via an embedded PSX engine or centralized PSX policy server
- New IP-based multimedia services beyond VoIP (IM, presence, Web 2.0);
- Superior protection against network attacks, overload and outages whilepreserving stateful call handling
- A proven SIP trunking solution with support for multiple SIP variants from IP-PBX vendors
- Built-in media transcoding featuring custom-built DSP firmware
Best-in-Class Performance Density
The SBC 5200 employs the latest generation of network processors, computing processors and digital signal processors (DSPs) to deliver the highest performance density SBC on the market combined with integrated transcoding, media interworking and native support for IPv6 addressing.
The SBC 5200 is the first product to combine full SBC functionality with media interworking, an advanced routing and policy engine and multi-access security gateway features in a single two-rack unit (RU) form factor. This unique combination of functionality addresses the evolving SBC market requirements, replacing multiple disparate network elements with a single SBC 5200 – without compromising scale or features.
A robust suite of security features is provided for both signaling and media. Encryption is available as TLS or IPSec for signaling and Secure RTP for media. Other security features include traffic policing, DoS and DDoS attack detection and blocking and rogue RTP protection.
With the ability to add optional DSP processing modules, the small form factor of the SBC 5200 also provides integrated media services including media transcoding, DTMF relay and interworking, and support for data (modem) and T.38 fax relay or interworking.
QoS/Service Level Assurance
In order to ensure the highest quality of service, the SBC 5200 offers a wide range of features. Call Admission Control (CAC) regulates the number of calls that are admitted into the system based upon policy decisions. Individual flows into the system are managed with regards to their bandwidth utilization and packet rate. Policy decisions allow packets to have their QoS parameters marked based upon carrier policy rather than those selected by the user. Registrations and calls are rate limited to prevent malicious or misbehaving endpoints from causing overload conditions. If overload conditions do occur, then the SBC 5200 maintains existing calls/registered endpoints, permits emergency and priority calls, while preventing new calls/new registrations from being admitted until the overload condition has passed.
Miercom Performance Verified
Sonus Networks engaged Miercom to evaluate the call handling capability of the SBC 5200 under specific adverse use case scenarios Download the Miercom Session Border Controller SBC 5200 Lab Testing Summary Report which overviews key findings and conclusions:
SBC 5200 successfully registered 256,000 user authenticated Total IADs in 16 minutes at a rate of 550 registrations per second during a simulated metro area outage and recovery scenario.
The SBC 5200 demonstrated outstanding CPU and Allocated Memory utilization throughout all tests. Miercom observed that these resources were rarely stressed and never maximized.
Sonus SBC 5200 maintains scalable call processing while under attack from spoofed IPs. In a maximum configuration, it supports up to 64,000 concurrent calls
Advanced Lights Out Management (ALOM) internal controller allows for device management and reporting during a system outage.
