A Session Border Controller (SBC) is a network device that secures voice over IP (VoIP) infrastructures while providing interworking between incompatible signaling messages and media flows (sessions) from end devices or application servers. SBCs are employed in enterprise infrastructures and any carrier network delivering commercial, residential, business, fixed-line, or mobile VoIP services. They are typically deployed at both the network edge and at carrier interconnects, the demarcation points (borders) between their users and other service providers.
The Dialogic® BorderNet™ SBC is a scalable high-performance software SBC that reduces CAPEX and OPEX while providing investment protection through simplified architecture, flexible deployment models, and automation-enabling points of integration. The BorderNet SBC enables mobile and fixed network service providers to interconnect and to deliver innovative IP-based services directly and through SIP trunks. The BorderNet SBC delivers unmatched performance, interworking, ease-of-use and advanced routing in a cost-effective, compact platform for a low total cost of ownership (TCO). The portable BorderNet SBC software provides investment protection by enabling easy transition from a commercial off-the-shelf (COTS) deployment model to a virtualized private or public cloud deployment model.
So Why the BorderNet SBC?
With multiple options for SBCs on the market today, why should you choose the BorderNet SBC? There are several reasons. The BorderNet SBC has new cutting-edge technology, combined with high performance and scalability, making virtualized communication networks safer, faster, and easier to connect. It is well suited for use in the complex networking world, supporting many features such as topology hiding, built-in firewall, dynamic access control lists and black lists, protection against denial-of-service (DoS) attacks, real-time message syntax, and semantics inspection. The BorderNet SBC also supports encryption, including TLS, IPsec, SRTP pass-through, and HTTPS. In addition to all these features, real-time analytics and an inviting GUI make the user experience much easier and smoother.
Secure network connectivity isn’t always easy to achieve. Service providers are challenged to easily and securely connect and deliver services to other operators, enterprises, and end users – encompassing a wide and varying range of SIP implementations. The Dialogic BorderNet SBC SIP Profiler reduces the complexity of SIP interworking and speeds time to revenue for new customers and services. The SIP Profiler can be used to define and customize BorderNet SBC behavior at the ingress and egress ports and enable customized routing to help optimize and control SIP message flows. The SIP Profiler is accessed through the integrated BorderNet SBC WebUI or through the use of XML scripts. Types of operations that can be performed using the SIP Profiler include:
- Add, modify or delete SIP headers, SIP bodies, and SDP parameters and adaptively impact message sequence and flows
- Store information from header fields for later access
- Inspect SIP messages for specific content
- Use customized response codes when, for example, rejecting messages
This ability to reduce the complexity of SIP interworking is critical in addressing the varying use cases supported by the BorderNet SBC, including
- Interconnecting diverse mobile, fixed, and cloud-based networks
- Interworking between IP Multimedia Subsystem (IMS), Voice over LTE (VoLTE), IPX networks, NGN SIP and H.323 networks
- Enterprise SIP trunks
- Residential and business VoIP services
- Hosted unified communications (UC) and contact center services
- Distributed SIP peering leveraging virtualized environments
- Detecting and reducing fraud
- Lawful Interception
- IPv4 to IPv6 migration initiatives
- Managing multiple peering partners
- Traffic cost optimization and service quality improvement
- Data center provider Infrastructure as a Service (IaaS) applications
Using an SBC to Save Money
The right SBC can help you reduce costs. The BorderNet SBC offers great scalability for addressing both enterprise and network deployments, supporting up to 100,000 simultaneous sessions at 1,000 sessions per second on a single HP DL380 server, leading to a smaller footprint, which can lower OPEX and CAPEX requirements.
It has the same software and features for all applications and deployment models – bare-metal deployment on commercial-off-the-shelf (COTS) servers, virtualized, and cloud – which translates into investment protection with lower OPEX through consistent operational characteristics across all applications.
The BorderNet SBC supports dynamic virtual CPU allocation, which also reduces CAPEX through highly efficient compute resource utilization while maximizing performance. It also features powerful and easy-to-use SIP header manipulation tools and profile-based provisioning, which accelerate service deployment while simplifying complex tasks associated with provisioning and interconnection, saving time and money.
A distributed and de-coupled analytics infrastructure, with real-time dashboard and reporting, improve operational efficiency and detect fraud through interactive visualizations and business intelligence reporting.
All of these features lead to a reduced total cost of ownership.
