Acme Packet Showcases IMS-E, Secure Net-Net Session Border Controllers

Acme Packet, a maker of session border control platforms, this week at VON unveiled IMS Enterprise (IMS-E), a set of capabilities that helps deliver IP Multimedia Subsystem (IMS) services to wireline enterprise customers.

Acme Packets IMS-E uses the same functionality foundation as the companys Net-Net family of session border controllers, which has supported both the 3GPP and TISPAN versions of the IMS specification for nearly a year. The IMS-E suite, said Joe McGarvey, Current Analysis senior analyst for carrier IP telephony, aims to provide enterprise-specific functions that the specifications do not address.

Nearly all discussions regarding IMS from vendors and service providers have focused on what IMS can do in terms of reducing a carriers operating expenses or facilitating the rapid creation of new revenue generating services and applications, he said. The IMS-related announcement is beneficial to Acme Packet, because it allows the company to restate its support for 3GPP/TISPAN functional modules, despite the fact that the prescribed functionality in that portion of the IMS specification is still in a period of flux and development. Acme, in providing periodical updates, is demonstrating that it is able to keep pace with the rate of modification in the standards groups.

Acme Packet said its IMS-E includes support for eight enterprise-specific requirements:

Surrogate registration of IP PBX & IAD endpoints

H.323 IP PBX – SIP IMS interworking

SIP IP Centrex service support

VPN bridging

Adaptive NAT/firewall traversal

DoS/DDoS protection for SBC and IMS core elements

Overload protection for IMS core elements


While enterprises generate the most profits for communications service providers today, IMS is functionally deficient in enabling service delivery to their most valuable customers, said Seamus Hourihan, Acme Packets vice president of marketing and product management. Acme Packets IMS-E fills the gaping holes.

Acme Packets also said it will demonstrate its Net-Net session border controllers with Net-SAFE security capabilities this week at VON.

The deployment of IMS architectures will require bullet-proof security to be successful. However, protection against DoS and DDoS attacks is not even addressed by IMS, ETSI TISPAN, MSF or any other next-gen architecture, said Hourihan. Our session border controllers provide the protection required by service providers to deliver trusted, first class IMS services.

The Net-Net session border controller security features on display include self-protection against DoS and distributed DoS attacks, access control, topology hiding, and service infrastructure DoS and overload prevention.
