M3UA RFC.4666 – SS7 MTP3 User Adaptation Layer

However, in the context of an SG, the maximum octet block size must be followed when interworking to a SS7 network that does not support the transfer of larger information blocks to the final destination. Failover also applies upon the return to service of a previously unavailable M3ua rfc 4666 Server Process. The provisioning and configuration of the M3ua rfc 4666 network determines the restriction placed on the maximum rcc.

This is to take advantage of various SCTP features, such as: Signalling Point Code Representation Failover – The capability to reroute signalling traffic as required to an alternate 466 Server Process, or group of ASPs, within an Application Server in the event of failure or unavailability of m33ua currently used Application Server Process. Signaling Transfer Point STP – M3ua rfc 4666 node in the SS7 network that provides network access and performs message routing, screening and transfer of signaling messages.

Protocol Architecture The framework architecture that has been defined for SCN signalling transport over IP [ 12 ] uses multiple components, including a common signalling transport protocol and an adaptation module to support the services expected by a particular SCN signalling protocol from its underlying protocol layer.

The delivery mechanism should meet the following criteria: Routing Context values are configured either using a configuration management interface, or by using the routing key management procedures defined in this document. Stream – An SCTP stream; a unidirectional logical channel established from one SCTP endpoint to another associated SCTP endpoint, within which all user messages are delivered in-sequence except for those submitted to the unordered delivery service.
