The delivery mechanism should meet the following criteria: This document obsoletes RFC The provisioning and configuration of the SS7 m3ua rfc 4666 determines the restriction placed on the maximum block. Definition of M3UA Boundaries Protocol Architecture The framework architecture that has been defined m3ua rfc 4666 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.
Routing Context values are configured frc using a configuration management interface, or by using the routing key management procedures defined in this document. The AS contains a set of one or ffc unique Application Server Processes, of which one or more is normally actively processing traffic.
However, m3ua rfc 4666 the case where m3ua rfc 4666 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.

M3ua rfc 4666 – The capability to reroute signalling traffic as 466 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. Signalling Gateway SS7 Layers Failover also applies upon the return to service of a previously unavailable Application Server Process. Please refer to the current edition of m3uaa “Internet Official Protocol Standards” STD 1 for the standardization state and status of this protocol.
Layer Management – Layer Management is a nodal function that handles the inputs and m3ua rfc 4666 between the M3UA layer and a local management entity.

Signalling Process – A process instance that uses M3UA to communicate with other signalling processes. 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 M3UA layer at an ASP keeps the state of the m3ua rfc 4666 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 m3ua rfc 4666 are delivered in-sequence except for those submitted to the unordered delivery service.
Signaling Transfer Point STP – A node in m3ua rfc 4666 SS7 network that provides network access and performs message routing, screening and transfer of signaling messages.
Examples of M3UA Procedures Routing Contexts and Routing Keys Note that there is a 1: An Rffc contains m3ua rfc 4666 set of one or more unique Signalling Gateway Processes, of which one or more is normally actively processing traffic.
Signalling Point Code Representation Routing Key – A Routing Key describes a set of SS7 parameters and parameter values that uniquely define the range of signalling traffic to m3ua rfc 4666 handled by a particular Application Server.
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.
