The experienced team at Metaswitch has developed a fully portable Session
Border Controller (DC-SBC) source code solution designed especially for system
vendors. Metaswitch's extensive VoIP and IP routing heritage provides
OEMs with a field-hardened SBC product that is deployable immediately, delivering
dramatic cost and time-to-market savings. The solution also includes many
of the essential control functions required in an IMS environment. Like all
Metaswitch products, DC-SBC is developed to the highest quality standards,
and the Session Border Controller architecture is designed for unparalleled
modularity, flexibility, scale, and reliability.
Metaswitch's Session Border Controller product offers vendors a best of breed solution which offers all of the key features
and the high performance and availability characteristics required by Service Providers and Enterprisers using Session Border
Controllers in their networks.
DC-SBC is available to OEMs as a complete solution or can be modularized to incorporate indvidual components. Both solutions are
highly portable and can be integrated seamlessly with any hardware and operating system as well as with existing, field-deployed
systems including softswitches and routers.

Metaswitch's DC-SBC product can also be used to provide many of the essential control functions required in an
IP Multimedia Subsystem (IMS).
Metaswitch's Session Border Controller solution combines a number of key benefits.
Compelling Cost Savings
Session Border Controllers support a wide range of functions including signaling, security, interworking, QoS, call control,
and billing. Developing, testing, and maintaining such a broad set of requirements is a costly undertaking, requiring millions
of investment dollars and manpower. Metaswitch estimates that developing full SBC functionality in-house would cost OEMs over
$25 million, which does not include recurring enhancement and maintenance costs. Metaswitch offers DC-SBC at a fraction of the
cost and provides support, updates, and code improvements at a nominal annual fee.
Quickest Time To Market
OEMs looking to develop Session Border Controller function internally would require years of development time. Metaswitch
estimates the workload at 100 man-years and the efforts and track record of the current stand-alone SBC vendors validates that figure.
Metaswitch now offers full SBC functionality in source code that is pre-ported with all of the leading operating systems
including Linux, OSE, QNX, Solaris, VxWorks, and Windows. OEM lead times and scheduled risk are reduced from years to months
Field Proven Technology
DC-SBC is built on a foundation of proven and field-hardened VoIP signaling technology. At the heart of DC-SBC is the full suite
of Metaswitch's portable VoIP products, DC-SIP and DC-Megaco/H.248. These products have been shipping since
2001, and have been field-hardened and deployed in a wide variety of VoIP devices.
In addition, DC-SBC has been extensively tested against a broad range of other SBC and VoIP equipment at SIPit
interoperability events since 2005.
Flexible And Modular Integration Options
DC-SBC and the IMS functions are extremely modular in that the two primary components (DC-SIG and DC-MEDIA) may be integrated together
as a complete solution or licensed individually to be deployed with existing third party implementations. Furthermore, each Metaswitch
component may be distributed independently to separate hardware modules or geographical locations. This highly modular architecture
enables DC-SBC and the IMS solutions to be deployed in a wide variety of network architectures and in a very scaleable fashion.
Carrier-grade Scale And Reliability
The DC-SBC modular architecture makes it simple for OEMs to distribute components over different hardware locations, allowing a
massively scalable solution. DC-SBC supports hundreds of thousands of concurrent sessions and our non-blocking design allows highly
scaled call control to run efficiently in both single and multi-threaded environments. Its redundant framework also enables fault
tolerance and high availability, including non-disruptive fail-over to backups (1:1 or 1:N). For more information on Metaswitch
high availability, see our High Availability Framework page.
Intelligent Dos Detection And Prevention
DC-SBC offers advanced Denial of Service (DoS) attack detection and prevention which goes far beyond the normal CAC policies
offered by traditional SBC solutions. DC-SBC uses dynamic blacklisting for attacks, which prevents malicious endpoints from
attempting to prevent provision of service to others. Metaswitch's DoS detection can intelligently identify various types of attack and
implement specific protection strategies based on attack type.
The focus of support at Metaswitch is to make our customers' developments successful. We believe that the quality of support
available is a key differentiator when licensing software. This means that we do not restrict ourselves to supporting just the software
we supply, but also encourage customers to use our expertise in the relevant technologies.
