Session border controllers: Rationalizing the border of the network

Dialogic

As service providers transform their networks more and more to IP, they are taking on a new role that involves the orchestration of applications and content from multiple participants in the service delivery supply chain. This translates into multiple networks - both internal and external to service providers - for providing end-to-end services to customers.

The multiplying capabilities and expanding capacities of Session Border Controllers (SBCs) have become central to this evolution to IP-to-IP interworking and can help service providers as they endeavor to improve performance and cope successfully with spiraling traffic volumes and complexity.

From once being looked upon as primarily a security device, SBCs have taken on an expanded role for fostering successful connectivity and providing high quality IP service. They can provide vital support for SIP normalization, QoS, NAT traversal, IPv4-IPv6 interworking and support for a host of value added services, and much more.
