M3UA RFC.4666 – SS7 MTP3 User Adaptation Layer

Failover also applies upon the return to service of a previously unavailable Application Server Process. This can be achieved using the.

Routing Context values are configured either using a configuration management interface, or by using the routing key management procedures defined in this document. Signalling Process – A process instance that uses M3UA to communicate with other signalling processes.

It serves as an active, backup, load-sharing, or broadcast process of a Signalling Gateway. Routing Key Management Procedures m3ia Layer Management – Layer Management is a nodal function that handles the inputs and outputs between the M3UA layer and a local management entity. An example scenario is where an SG appears as an. However, in the case where an ASP is connected to more than one SG, the ,3ua layer at an ASP should maintain the status of configured SS7 destinations and route messages according to the availability and congestion status of the routes to these destinations via each SG.

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.

Note that there is a 1: Message Distribution at the SGP This document obsoletes RFC Table of Contents 1.

Please refer to the current edition of the “Internet Official Protocol Standards” STD 1 for the standardization state and status of this protocol. 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 k3ua destination. The AS contains a set of one or more unique Application Server Processes, of which one or more is normally actively processing traffic.

This is to take advantage of various SCTP features, such as: Definition of M3UA Boundaries Examples of M3UA Procedures Signaling Transfer Point STP – A node in the SS7 network that provides m3au access and performs message routing, screening rc transfer of signaling messages.

Signalling Gateway SS7 Layers Message Classes and Types Message Distribution at the ASP Routing Context – A value that uniquely identifies a Routing Key. Receipt of Primitives from the Layer Management 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 M3ya signalling protocol from its underlying protocol layer.

Linkset – A number of signalling links that directly interconnect two signalling points, which are used as a module. Signalling Point Code Representation Managing Routing Contexts and Routing Keys Routing Contexts and Routing Keys An SG contains a set of one or more unique Signalling Gateway Processes, of which one or more is normally actively processing traffic.

Failover – The capability to reroute signalling traffic as required to an alternate Application Server Process, or group of ASPs, within an Application Server in the event of failure or unavailability of a currently used Application Server Process.
