Receipt of Primitives from the Layer Management Please refer to the current edition of the “Internet Official Protocol Standards” STD 1 for the standardization state and status of 44666 protocol. Linkset – A number of signalling links that directly interconnect two signalling points, which are used as a module.

Network Byte Order – Most significant byte first, a. The provisioning and configuration of the SS7 network determines the restriction placed on the maximum block. Layer Management – Layer Management is a nodal function that handles the inputs and outputs between the M3UA layer and a local management entity.

Distribution of m3ia memo is unlimited. Note that there is a 1: This can be achieved using the.

Routing Context – A value that uniquely identifies a Routing Key. Message Classes and Types M3ja Context values are configured either using a configuration management interface, or by using the routing key management procedures defined in this document. However, in the case where an ASP is connected to more than one SG, the M3UA 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.

The delivery mechanism should meet the following rrfc Message Distribution at the SGP Routing Contexts and Routing Keys Network Working Group K. The AS contains a set of one or more unique Application Server Processes, of which one or more is normally actively processing traffic.

Signalling Process – A process instance that uses M3UA to communicate with other signalling processes.

M3UA RFC.4666 – SS7 MTP3 User Adaptation Layer

An SG contains a set of one gfc more unique Signalling Gateway Processes, of which one or more is normally actively processing traffic. The M3UA layer at m3ka ASP keeps the state of the routes to remote SS7 destinations and may initiate an audit of the availability and the restricted or the congested state of remote SS7 destinations.

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. Definition of M3UA Boundaries Managing Routing Contexts and Routing Keys 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 m3ka layer.

An example scenario is where an SG appears as an. Examples of M3UA Procedures Message Distribution at the ASP 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.

Routing Key Management Procedures [Optional] This is to take advantage of various SCTP features, such 44666 Signalling Point Code Representation 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.
