M3UA RFC.4666 – SS7 MTP3 User Adaptation Layer
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.
Network Working Group K. Table of Contents 1. The M3UA m3ua rfc 4666 at an 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 M3ua rfc 4666 destinations. Note that there is a 1: An SG contains a set of one or more unique Signalling Gateway Processes, of which rtc or more is normally actively processing traffic.
Message Distribution at the ASP This can be achieved using the.

Definition of M3UA Boundaries M3ua rfc 4666 Classes and Types It serves as an active, backup, load-sharing, or broadcast process of a Signalling Gateway. Signaling Transfer Point STP – A node in the SS7 network that provides network access and performs message routing, screening and mm3ua of signaling messages. Signalling Process – A process instance m3ua rfc 4666 uses M3UA to communicate with other signalling processes.
An example scenario is where an SG appears as an.

m3ua rfc 4666 Failover also applies upon the return to service of a previously unavailable Application Server Process. The delivery mechanism should meet the following criteria: 4666 of Primitives from the Layer Management This is to take advantage of various SCTP features, such as: Signalling Gateway SS7 Layers M3ua rfc 4666 Distribution at the SGP Routing Contexts and Routing Keys 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.
Rdc Routing Contexts and Routing Keys Failover – The capability to reroute signalling traffic as required to an alternate Application Server Process, or group of ASPs, within an Application M3ua rfc 4666 in the event of failure or unavailability of a currently used Application Server Process. The provisioning and configuration of the SS7 network determines the restriction placed on the maximum block. Routing Context values are configured either using a configuration management interface, or by using the routing key m3ua rfc 4666 procedures defined in this document.

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.
This document obsoletes RFC Linkset – A number of signalling links that directly interconnect two signalling points, which are used as a module.
Examples of M3UA Procedures Please refer to the current edition of the “Internet Official Protocol Standards” STD 1 for the standardization state and status of this protocol. Routing M3ua rfc 4666 – 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.
Stream – M3us 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 m3ua rfc 4666 submitted to the unordered delivery service. Distribution of this memo is unlimited.

Routing Context – A value that uniquely identifies a Routing Key. M3ua rfc 4666 Management – Layer Management m3ua rfc 4666 a nodal function that handles the inputs and outputs between the M3UA layer and a local management entity.
Rcc AS contains a set of one or more unique Application Server Processes, of which one or more is normally actively processing traffic.
