 all major IMS core infrastructure vendors around the world

BURLINGTON, MA, OCTOBER 16, 2008 — Acme Packet® (NASDAQ: APKT), the leader in session border control solutions, today provided an update on its IMS projects, which now total nearly 100 around the world. The update is the result of a recently completed survey and analysis conducted by Acme Packet.

Highlights of the analysis reveal the following:

  • European deployments lead the way: Acme Packet is involved in IMS projects in every economic region of the world. European service providers account for 50% of Acme Packet’s IMS projects, followed by 22% in Asia-Pacific, 15% in Central & South America and 13% in North America. The large concentration of projects in Europe reflects both the number of unique tier-one service providers in that region and their overall receptivity to the European-focused 3GPP and ETSI standards groups defining IMS.

  • Interoperability with all major IMS vendors proven: Acme Packet SBCs are deployed with IMS core infrastructure (e.g., S/I-CSCF, HSS, application servers, etc.) provided by eight different major communications equipment vendors. Given the early and evolving state of implementing IMS standards, this demonstrates Acme Packet’s flexibility should IMS elements be changed or additional endpoints be supported.

  • Wireline service delivery commands attention: Nearly two-thirds of Acme Packet’s IMS projects (65%) deliver services only to wireline access networks. Both wireline and wireless networks are supported by 26% of the projects and wireless-only networks by 9%. These findings support our observation that wireline access networks are moving more rapidly to IP for voice service delivery than wireless access networks. All IP 4G networks such as mobile WiMAX and LTE present future new opportunities for IMS.

  • Access border is the SBC focus: Given the initial focus by service providers on delivering services to their own subscribers, SBCs are initially being used to protect and control the access border in 80% of Acme Packet’s IMS projects. In another 13% of the projects, SBCs are being used at both the access and interconnect borders, and in the remaining 7% of projects at the interconnect border only. Interconnecting these networks to one another and non-IMS VoIP networks is an additional future opportunity.

  • Integrated SBC architecture prevails: Acme Packet’s integrated SBCs, which control both SIP signaling and media, have been selected, on average, for nine out of ten projects. The other projects are using an Acme Packet’s decomposed SBC solution – a border gateway controlling just media under the direction of another vendor’s SIP signaling element. In contrast with the decomposed SBC architecture, the integrated SBC provides superior border control functionality and performance, and is field-proven in hundreds of Acme Packet customer networks and in networks with hundreds of border points. The integrated SBC solution simplifies the network by eliminating the need for the H.248 control protocol between elements and greatly eases troubleshooting and support by consolidating border control in one system from a single vendor.

In July 2008, ABI Research released its IMS Vendor Matrix and placed Acme Packet eighth among the top ten IMS suppliers based on various criteria, including announced orders or trials, the number of tier-one operators that are customers, the number of elements provided and the number of applications supported.

In addition, Current Analysis recently ranked Acme Packet’s Net-Net 4000 family first among its peers on several categories, including IMS and protocol support and customer traction.

“Acme Packet is an industry leader in the standalone SBC market in multiple categories and a trendsetter in terms of supporting emerging architectures, protocols, interfaces and deployment scenarios,” said Joe McGarvey, principal analyst for Current Analysis. “Acme Packet’s support of IMS standards and broad range of early IMS customers puts the company in a strong position among competitive suppliers.”

 “While IMS architectural blueprints don’t explicitly specify the need for a ‘session border controller’ by that name, our survey results show that our customers believe otherwise,” said Seamus Hourihan, vice president of marketing and product management for Acme Packet. “The session border controller is the right product to perform all of the IMS network access and interconnect edge functions and satisfy several critical requirements missing from IMS in the areas of security, overload control, enterprise service delivery, and overall resiliency and scalability.”

Information about the role of Acme Packet’s session border controllers in IMS architectures, including 3GPP, ETSI TISPAN, Multiservice Switching Forum and PacketCable, is available on Acme Packet’s website. About Acme Packet
