Overview Refresher Ability for intermediaries to stay in the Diameter signaling path during a session (e.g. an outgoing gateway for a domain enforcing policy) Updates since IETF 68/69 Proposes new “workarounds” to provide explicit routing without using new routing AVPs Introduce intermediate proxy nodes that are session stateful Session stateful nodes can select the next hop node to send session messages to Retain old scheme Use new routing AVPs that keep track of nodes to visit Added more use case scenarios; i.e. 3GPP |
