标签: diameter-protocol

I read that CER has to send multiple vendor specific application ids to advertise all the applications that the diameter node supports. If that is true then what is the application id value in the diameter header. Also I dont understand when when the following three are to be used- Acct Application id AVP, vendor specific application id AVP and Auth Application id

无论您要发送哪个Diameter请求,标题中的ApplicationId始终存在。 因此,它也有CER(见RFC 3588第3节)

CER:

您应该在会计类型的数据包中使用Acct-Application-Id AVP(参见RFC 3588第6.9节) 您应该在身份验证和授权类型数据包中使用Auth-Application-Id AVP(参见RFC 3588第6.8节)

Vendor-Specific-Application-Id AVP用于支持供应商特定的Diameter应用程序,为了描述它,您必须添加Acct-Application-Id AVP或Auth-Application-Id AVP(参见RFC 3588部分) 6.11)
