Most Session Border Controller (SBC) deployments combine purpose-built processing with signaling and media controls in a single appliance or network element to stop front-line of DOS or DDOS attacks. But as organizations virtualize and move to the cloud, they want the type of scalability and flexibility not generally available with hardware. As a result, a new breed of SBCs has emerged—virtualized and fully orchestrated—to work well in software-defined environments, particularly those using white-box solutions from managed service providers that lack robust security for VoIP and SIP. The virtualized SBCs can be used on both the customer and service provider ends when firewalls do not provide enough protection, with security functions delivered via software implemented on devices, such as IP PBXs, to stop network intrusions and provide network management and transcoding.
In addition to agility, elasticity, and freedom from proprietary hardware, virtualizing SBCs means faster introduction of services and shorter innovation cycles. Additionally, multitenancy is addressed by dedicating one or more instances of an SBC to a customer, which also means scalability on demand and improved user experience and SLA adherence.
Oracle Communications has built out a robust set of requirements for VoLTE, video calling and conferencing, SIP trunking and hosted services, HD voice and RCS, and WebRTC, as shown in the table below.
With new SBC and VoLTE technology, Oracle Communications is focused on powering networks of the future, building SBCs that enable trusted communications across IP network access borders and IP interconnect borders, including fixed line, mobile (VoLTE), and OTT services.
