IP Telephony news wrap-up for Mar 20 – 2007

Acme Packet’s Net Net SBCs now support the Diameter protocol towards policy
servers and CLFs. The vendor is working to establish interopability with
policy servers supplied by CableMatrix, Camiant, Juniper and Operax.

Diameter is an authentication, authorization, and accounting protocol and is
used for several IMS functions including the interface between SBCs and
policy servers for resource reservation for VoIP and other interactive IP
communication sessions.

The Diameter implementation allows the SBC to perform call admission control
by making bandwidth requests to an external, centralized RACF/PDF policy
server. When the Net-Net SBC receives a SIP Invite it requests bandwidth
from a policy server via Diameter or COPS. The policy server determines
whether bandwidth is available and sends a message back to the Net-Net SBC
either accepting or rejecting the bandwidth request. If resources are
granted, the SBC continues with call set-up or rejects the session
gracefully if bandwidth or QoS is not available.
