Diameter Edge Agent (DEA)
A Diameter Edge Agent provides the extra security communications service providers (CSPs) require to connect securely with third-party partners when needed and share resources, such as in roaming and billing use cases. It does this by enabling Diameter signaling messages to flow smoothly among networks while also adequately disguising the topology of both networks.
Its normalization engine ensures that only supported AVPs (attribute-value pairs) and content enter the network. A Diameter Edge Agent can also protect Diameter servers—and the entire network—from overload conditions brought on by DoS attacks or other types of traffic overload.
Security, as a requirement to interoperability in a 4G LTE network, is essential to a CSP’s or an IPX carrier’s ability to capitalize on roaming. The F5 Traffix Signaling Delivery Controller (SDC) Diameter Edge Agent provides the enhanced security that CSPs need, enabling them to extend their capabilities in network signaling with confidence.
The SDC Diameter Edge Agent also enables tier one carriers to manage their mobile virtual network operator (MVNO) wholesale solutions. With its high security and failover protection, which is facilitated by masking the network to prevent unauthorized access, the Diameter Edge Agent ensures that external sessions are routed according to policies set by the CSP. It also ensures that each incoming or outgoing message is accurate, and it fixes or rejects problematic messages.
The SDC Diameter Edge Agent, fully compliant with GSMA IR.88 requirements for LTE, is just one component of the broader SDC platform that provides CSPs with comprehensive Diameter signaling capabilities. The F5 SDC can also be deployed as an interworking function (IWF) for SS7/Diameter connectivity, a Diameter load balancer, and a Diameter Routing Agent (DRA).
