What is cer Diameter?
The capabilities exchange message sequence, CER/CEA, is standard Diameter messaging used as a means of correlating client capabilities with server services. The CER message is used to discover peer’s identity and exchange capabilities, including applications supported, vendor-Id and device addressing information.
What is Diameter port?
Diameter Applications can extend the base protocol by adding new commands, attributes, or both. Diameter security is provided by IPsec or TLS. The IANA has assigned TCP and SCTP port number 3868 to Diameter, as stated in section 11.4 of RFC 6733.
Is Diameter UDP or TCP?
Like RADIUS, Diameter provides AAA functionality, but uses TCP and SCTP instead of UDP, therefore delegating detection and handling of communication problems to those protocols. Diameter Applications extend the base protocol by adding new commands and/or attributes.
What is a Diameter firewall?
The BroadForward Next Generation Diameter Firewall (BroadForward DFW) is a converged software solution which protects 4G networks against potential attacks, unauthorized senders, malformed messages, overload situations and much more.
How does diameter protocol work?
Diameter is a message based protocol, where AAA nodes exchange messages and receive Positive or Negative acknowledgment for each message exchanged between nodes. For message exchange it internally uses the TCP and SCTP which makes diameter reliable.
What is Radius and diameter protocols?
Radius is a connectionless protocol, so it do not need any session creation before its operation. But Diameter is a connection oriented like TCP. As a transport protocol, Radius uses UDP (User Datagram Prtocol) and Diameter uses TCP (Transmission Control Protocol) or SCP.

What is diameter use?
The diameter measures the circle at its largest point across. Another definition that is related to the diameter is the radius. It is the measurement from the center of the circle to its edge. The relation of the radius to the diameter gives us one of the formulas involving the diameter.
