Acme Packet Showcases Next-Generation Capabilities in 2008 Global MSF Interoperability Event

Acme Packet(R) (NASDAQ: APKT), the leader in session border control solutions, today announced it has successfully participated in the Global MSF Interoperability 2008 (GMI 2008) event, a worldwide multi-vendor interoperability test environment designed by the MultiService Forum (MSF) to test key service concepts that leverage IP Multimedia Subsystem (IMS) and next-generation network (NGN) infrastructures. Acme Packet demonstrated the capability of its Net-Net(R) session border controller (SBC) and the Net-Net session router proxy (SRP) in emerging next-generation architectures that included converged services across wireless and wireline access networks.

"The GMI 2008 event is the industry's largest real-world test bed for IMS and NGN architectures: solutions are validated, issues overcome and new approaches considered," said Joe McGarvey, Principal Analyst for Current Analysis. "The industry as a whole benefits from cooperative events like this that address the issues facing carriers planning for next-generation network migration."

Acme Packet was one of only four IP communications equipment vendors to test in every service provider location at GMI 2008. Acme Packet's Net-Net Session Director, a session border controller, and the Net-Net Session Router, a core session routing proxy, were tested in multi-vendor interoperability environments that included a broad range of traditional voice services and emerging broadband technologies, such as End-to-End Quality of Service (QoS) in WiMAX, 3GPP and Broadband Access scenarios, IMS-IPTV and Location Services testing. Acme Packet demonstrated support for numerous IMS functions including the Proxy-Call Session Control Function (P-CSCF) and Core Border Gateway Function (C-BGF) for controlling subscriber access, the Breakout Gateway Control Function (BGCF) for selecting the appropriate interconnect network and the Interconnect Border Control Function (I-BCF) and Interconnect Border Gateway Function (I-BCF) for controlling the interconnect/peering border.

"Events like GMI 2008 are a valuable proving ground for new technologies and approaches, enabling service providers to examine the pros and cons of various next-generation architectures," said Seamus Hourihan, vice president of marketing and product management for Acme Packet. "Acme Packet's experience in helping service providers around the world normalize disparate network infrastructures adds a critical element to these events as service providers continue to require trusted, first-class interactive IP communications in their next-generation architectures."
