Tech Stuff – SIGTRAN Introduction

Problems, comments, suggestions, corrections including broken links or something to add? MTP3 routes from point code to point code. It is a ‘glue’ layer and its functionality is not defined by the standards.

Needs the SCCP services. Each IPSP must have its own point code. A standard IP layer. A device that converts from one protocol to another. MTP3 routes the message back to the origination SP.

Allows gutorial messages to be delivered in the order in which there were sent. End-points exchange lists of addresses during initiation of the connection.

SCTP uses periodic heart-beat messages to confirm the status of each end point.

You tktorial, at no charge, upgrade to a W3C standards compliant browser such as Firefox. This interface is implemented with a set of messages that the application can tutorail to the M3UA layer on the TX communications processor.


If you are happy it’s OK – but your browser is giving a less than optimal experience on our site. SUA can enhance the efficiency of the network and provides a means for simpler implementations.

You will have a warm inner glow for the rest of the day. For more information, see M3UA service function summary. The primitives are described in Q.

M3UA layer

Routes messages to their IP destinations. Does not need SCCP services, reducing the complexity of the node and thereby reducing cost. The IPSPs do not require point codes. Allows for multiple virtual connections on the same physical line. This local PSP is created automatically, not configured. For more information, see M3UA message handling. A peer signaling process can be in an active or standby state. Each IP node is required to have a point code and an IP address.

Routing keys are defined using c ombinations of the following parameters: Each peer server serves a specific routing key. Automatically reroutes traffic in the case of failure or congestion.

View the status of the Tutoorial association by which the remote peer signaling process is reachable. For more information, see M3UA management function summary.

M3UA – Wikipedia

There is a one-to-one relationship between a peer server and a routing key. One address is designated as the primary address to receive data. Each user application might be assigned its own stream virtual connection.

SCTP’s multi-streaming allows data to be delivered in multiple, independent streams, so that if there is data loss in one stream, delivery will not be affected for the other streams.

Each M3UA instance can support up to associations. In case of network failures, use of more than one address can allow re-routing of tutoial, and also provide an alternate path for retransmissions.
