Bridgewater Systems AAA Service Controller Leads with New Support for Next-Generation

    Allows service providers to extend network access control to support 3G
and now 4G access technologies simultaneously

    ORLANDO, FLA., March 27 /CNW/ - Bridgewater Systems, a leading developer
of subscriber-centric policy management software for IP-based services, today
announced new support for its market-leading AAA Service Controller that
allows service providers to deploy this carrier-grade network access control
platform across 3G, and now 4G access networks such as WiMAX. Proven and
widely deployed, the AAA Service Controller incorporates mobile WiMAX
enhancements that build on existing Bridgewater technology and expertise in
providing best of breed AAA solutions in wireless networks. As a result,
service providers can extend networks to take advantage of innovations and
services made possible with next generation 4G networks and IP Multimedia
Subsystem (IMS)/Multimedia Domain (MMD) frameworks, with a common
carrier-grade network access control infrastructure that supports multiple
access technologies simultaneously including wireline, CDMA, GSM and now WiMAX

    Recognized as the most scalable and robust authentication, authorization,
and accounting (AAA) product of its kind, the AAA Service Controller enables
service providers to control access to advanced and differentiated services
across fixed, mobile and converged networks. A key component of Bridgewater's
extensive policy management portfolio, the AAA Service Controller demonstrates
the power of Bridgewater's access technology agnostic approach by providing
service providers with a vendor-neutral and network-neutral access control
platform. With a common policy and subscriber profile repository that serves
all access networks, service providers can create a unified view of
subscribers, realize operational efficiencies by eliminating the need to
reprovision subscribers as new access technologies such as WiMAX are
introduced, and accelerate time to market for new services.

    "Many AAA servers are not currently able to provide the scalability,
mobility and security support required for robust mobile WiMAX deployments,"
said Russ Freen, co-founder and chief technology officer for Bridgewater
Systems. "The enhancements to our flagship AAA Service Controller are the
result of Bridgewater's pedigree in carrier-grade AAA and mobility solutions
that meet the most demanding performance requirements in service provider

    As service providers extend networks with WiMAX, Bridgewater offers a
proven AAA solution with extensive mobile WiMAX support such as device
authentication and mobile IP. The latest enhancements to the AAA Service
Controller feature dual-stack RADIUS/Diameter support, allowing service
providers to migrate to new network variants such as WiMAX 1.5 and IMS
frameworks, where Diameter and/or RADIUS protocols are required. Because the
AAA Service Controller supports RADIUS and Diameter interfaces simultaneously,
service providers can deploy a common multi-protocol network access platform
to protect their investment in legacy applications and services and leverage
new SIP-based services as they migrate to next-generation networks and IMS/MMD

    "Concurrent support of the RADIUS and Diameter protocols on a single
network access control platform constitutes an important value proposition for
service providers who are offering their services across multiple access
networks, each with their own specific protocol requirements," commented
Ronald Gruia, Principal Telecom Analyst at Frost and Sullivan. "Multi-protocol
support provides operators with a cost-effective and flexible approach that
supports migration strategies to next generation networks and frameworks,"
added Gruia.

    The AAA Service Controller also provides broader security awareness
required for mobile WiMAX, with new support for supplementary authentication
protocols such as Extensible Authentication Protocol (EAP), including
EAP-Transport Layer Security (EAP-TLS) and EAP-Tunneled Transport Layer
Security (EAP-TTLS). Because it can support multiple EAP methods
simultaneously, the AAA Service Controller provides flexible support for a
seamless authentication experience for roaming mobile WiMAX subscribers, as
different operators may support different EAP authentication variants.

    Bridgewater continues to play a leading role in subscriber-centric policy
management for 4G technologies specifically WiMAX, with plans to evaluate
Ultra Mobile Broadband (UME) and Long Term Evolution (LTE). The AAA Service
Controller is in mobile WiMAX trials with a Tier-1 North American operator and
a number of Bridgewater channel partners, providing a best of breed AAA access
core in WiMAX deployments around the globe. As a principal member of the WiMAX
Forum, Bridgewater is actively involved in contributing to the development of
WiMAX standards, in particular the IEEE 802.16e mobile standard as it relates
to authentication, accounting, and policy management.

    These latest enhancements to Bridgewater's flagship network access
control solution come on the heels of last month's introduction of Application
Policy Controller (APC) and Network Policy Controller (NPC) products. Together
with the AAA Service Controller, these policy control solutions provide the
industry's most comprehensive portfolio of carrier-grade subscriber-centric
policy management offerings that allow operators to control and monetize
subscriber access to networks, applications and resources.
