A Diameter Edge Agent provides the extra security service providers 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.
