Note m3ua rfc 4666 there is a 1: An example scenario is where an SG appears as an. Signalling Process – Rcf process instance that uses M3UA to communicate with other signalling processes.

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.

Definition of M3UA Boundaries Routing Key – A Routing Key describes a set of SS7 parameters and parameter values that uniquely define the range of signalling traffic to be handled by a particular Application Server. Receipt of Mua from the Layer Management Routing Context – A value that uniquely identifies a Routing Key.

Routing Contexts and Routing Keys Message Classes and Types Linkset – A number of signalling links that directly interconnect two signalling points, which are used as a module. It serves as an active, backup, load-sharing, or broadcast m3ua rfc 4666 of a Signalling Gateway.

This can be achieved using the. An SG contains a set of one or m3ua rfc 4666 unique Signalling Gateway Processes, of which one or more is normally actively processing traffic. Distribution of this memo is unlimited. 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.


However, in the case where an ASP is connected to more than one SG, the M3UA layer at an ASP should maintain the status m3ua rfc 4666 configured SS7 destinations and route messages according to the availability and congestion status of the routes to these destinations via each SG.

Message Distribution at the ASP Examples of M3UA Procedures This document obsoletes RFC Routing Key Management Procedures [Optional] Layer Management – Layer Management is a nodal function that handles m3ua rfc 4666 inputs and outputs between the M3UA layer and a local management entity.
