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.

XConnect has developed a peering federation that it will manage in Brazil that includes five VoIP service providers consisting of Conceito Telecom, Easytone, iVoz.net, GlobalNova Comnicacoes, and Tellfree. The federation will enable its members to exchange VoIP traffic, completely bypassing the PSTN.

Terremark will provide Layer 2 private Ethernet connectivity and co-location services to the new group.

XConnect has one other peering federation, which includes a consortium of cable MSOs in the Netherlands.

D2 Technologies, a supplier of embedded software platforms that works with ICs and SoCs, has enhanced its vPort family of software versions to support VoIM protocols such as XMPP and the signaling protocols that deliver GoogleTalk, Yahoo!, MSN Messenger, and Gizmo. The vPort product line includes software for VoWLAN and dual mode mobile phones; CPE gateways, ATAs, routers, IADs, and triple play devices; IP phones and speakerphones; and cordless IP/VoIM phones.

vPort can execute on both RISC and CISC platforms. D2’s technology is interoperable with ICs and SOCs solutions from Cavium, Infineon, and Texas Instruments.
