Net-Net Diameter Director* provides critical security, routing and interoperability functions for LTE data and voice roaming and scaling all-IP networks
GSMA MOBILE WORLD CONGRESS, BARCELONA, SPAIN, FEBRUARY 14, 2011 — Acme Packet® (NASDAQ: APKT), the leader in session border control solutions, today unveiled the Net-Net® Diameter Director, a Diameter signaling controller (DSC)**. A DSC is a new class of product that addresses critical security, interoperability, routing and scaling challenges in next generation all-IP networks. The Net-Net Diameter Director supports multiple applications—LTE data and voice roaming, policy aggregation and federated service delivery—by enabling the exchange of policy information within service provider LTE or IMS networks and across LTE network borders.
Long Term Evolution (LTE) and IP Multimedia Subsystem (IMS) networks require the exchange of policy information among network elements for each subscriber data, voice and multimedia session. Diameter is the IP signaling protocol that supports this policy information exchange. A DSC is a new network element that controls Diameter signaling, enabling the seamless communication and control of policy information between network elements within LTE or IMS networks and across LTE network borders. These functions reduce costs, streamline networks and assure availability for LTE and IMS networks.
“Yankee Group believes that Diameter signaling controllers are essential building blocks in the all-IP world of LTE and IMS,” commented Brian Partridge, vice president, Network Research with Yankee Group. “Acme Packet is taking advantage of its IMS border control leadership and IP signaling expertise to define a new product category and launch a compelling solution to help service providers successfully grow their next generation networks.”
Diameter signaling controllers in LTE and IMS
Policy exchange involves the transmission of subscriber and session information related to authentication, authorization, location, charging and quality of service (QoS) in LTE and IMS networks. Using Diameter signaling, this exchange takes place between distinct network elements from different vendors as well as between different service providers. In the all-IP networks of LTE and IMS, Diameter signaling replaces the legacy SS7 signaling in legacy TDM mobile and fixed networks.
“As LTE and IMS networks grow in number and subscribers, Diameter-based policy exchange will become instrumental to service provider profits,” explained Seamus Hourihan, vice president of marketing and product management with Acme Packet. “Acme Packet is taking the lead in defining the Diameter signaling controller requirements and extending session border control to new networks and new protocols with the Net-Net Diamter Director.”
There are three primary applications enabled by DSCs:
- LTE data and voice roaming – DSCs secure the new Diameter signaling border between visited and home service providers so roaming subscribers can access both data and voice services. DSCs also enable IPX carriers and roaming hubs to deliver multilateral LTE roaming services.
- Policy aggregation – DSCs simplify the mesh of connections between a myriad of Diameter elements—including the Home Subscriber Server (HSS), Policy Charging and Rules Function (PCRF) and Mobility Management Entity (MME)—and ensure interoperability between different vendors and products within a service provider LTE or IMS network. They allow the network to scale cost-effectively and provide a centralized point for management and reporting of Diameter messages and connections.
- Federated service delivery – DSCs facilitate policy exchange between a network transport provider and a service provider, such as a mobile virtual network operator (MVNO) or over-the-top/cloud provider, enabling new revenue-sharing business models while ensuring an optimal user experience.
Net-Net Diameter Director delivers superior Diameter control
The Net-Net Diameter Director is a standards-based Diameter proxy and fulfills functional elements defined by industry groups, including the 3GPP Diameter Routing Agent (DRA) and GSMA Diameter Edge Agent (DEA). The Net-Net Diameter Director supports numerous Diameter profiles used throughout IMS and LTE.
Employing Net-Net OS, Acme Packet’s feature-rich software, the Net-Net Diameter Director provides a comprehensive set of functions required to cost-effectively grow LTE and IMS networks. Acme Packet’s Net-SAFE® security framework, field-proven in large service provider networks, protects service provider LTE roaming borders, assuring service availability. The powerful and scalable routing engine of the Net-Net OS can make routing decisions on a flexible combination of Diameter message content and simplifies route management in the network. As a Diameter proxy with layer 3–layer 5 interworking, the Net-Net Diameter Director enables interoperability between vendors, elements and networks, expediting time to market. Aggregation and reporting of Diameter transactions simplifies roaming settlement as well as network planning and troubleshooting.
Operating on the Net-Net 4500 hardware platform, the Net-Net Diameter Director provides high-performance processing of Diameter messages—up to 16,000 messages per second in a single rack unit system. Scaling to over 750,000 messages per second in a 7-foot telco rack, the Net-Net Diameter Director provides leading performance capabilities with compelling price-performance advantages. For voice over LTE (VoLTE) roaming applications, the Net-Net Diameter Director can be integrated with Acme Packet’s industry-leading Net-Net session border controller (SBC). This integration seamlessly combines SIP and Diameter security and controls in the same physical system, providing a low total cost of ownership.
More information on the Net-Net Diameter Director and related solutions will be available at Acme Packet’s hospitality suite AV38 at GSMA Mobile World Congress taking place February 14-17 in Barcelona, Spain. To learn more, schedule a meeting at the event.
Yankee Group, a leading industry analyst firm, recently released a whitepaper entitled Policy Exchange Controllers: Enriching Diameter Signaling for LTE and IMS that explores the key challenges and requirements for operators deploying LTE and IMS networks at significant scale, including defining policy exchange controllers as critical elements to success.
