A Session Border Controller, or SBC for short, is a major component of telecommunication service providers. For end users, this equipment piece is rarely visible. It is, however, an essential element of the complete solution to provide a solid experience for VoIP unified communications.
The main roles of SBCs are to secure and control SIP networks (Session Initiation Protocol) used by VoIP applications such as unified communications. SBCs are, by definition, installed at the network’s border in a service provider’s data center.
The foremost reason that telecommunication service providers use an SBC is to secure its VoIP network. As with any IP network, there exist risks of unwanted intrusions, or hacking. Session Border Controllers thus have the vital role of acting like a specialized firewall to protect the telecommunication service provider network as well as the customer’s. Among some of the most common attacks are DDoS and IP spoofing.
Although often less regarded, the role of a Session Border Controller is to improve the reliability of telecommunication service providers networks providing VoIP unified communications. Because SBCs provide real-time computational services such as SIP translation, intelligent routing and QoS (Quality of Service), they allow offloading other network components.
Offloading certain tasks while processing others increase network reliability while also providing scalability to handle increased traffic.
The use of Session Border Controllers by telecommunication service providers is proof of their seriousness, professionalism and expertise. However, there still exists several industry suppliers that do not use a telco grade SBC.
For its part, IP4B has partnered with Ribbon Communications and its Sonus Session Border Controller. Ribbon Communications is the world leader in its field and is used by large telecommunication service providers such as Bell Canada, British Telecom (BT), Verizon, CenturyLink and Deutsche Telekom.
A Session Border Controller, or SBC for short, is a major component of telecommunication service providers. The main roles of SBCs are to secure and 1control SIP (Session Initiation Protocol) networks and to ensure the network’s reliability.
The use of Session Border Controllers like those from Ribbon by IP4B is proof of our professionalism and expertise for our VoIP unified communications clients.
