Tech Stuff – SIGTRAN Introduction
MTP3 routes from point code to point code. For more information, see M3UA service function summary. A single IP port number is used across the entire address list at an endpoint for a specific session.

A routing key defines the range of signaling traffic to be handled by a particular peer server. Peer servers can be local or remote.

It is a ‘glue’ layer and its functionality is not defined by the standards. Each NSAP is associated with a service indicator field and protocol variant combination. MTP3 routes the message back to the origination SP. SG is an SS7 node with a point code.
F or more information, see M3UA management function summary. SG is not an SS7 node and has no point code.
If you are happy it’s OK – but your browser is giving a less than optimal experience on our site. This interface is tutorail with a set of messages that the application can pass to the M3UA layer on the TX communications processor.
The whole IP network is represented by a single point code that addresses the MGC at the network edge. One address is designated as the primary address to receive data. 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 IPSP must have its own point code. Please take the time from a busy life to ‘mail us’ at top of screenthe webmaster below or info-support at zytrax.
The SCTP user can specify at startup time the number of streams to be supported by the association. M3UA uses a flexible configuration capable of supporting a wide variety of network routing and addressing tugorial.
Each IP node does not tuotrial a point code. Messages are handled from point code to point code. Each M3UA instance can support up to associations. Each peer server serves a specific routing key.
Needs the SCCP services. In case of network failures, use of more than one address can allow re-routing of packets, and also provide an alternate path for retransmissions. It performs these primary tasks:. The primitives are described in Q. Defined by RFC tuttorial The transport addresses used by the endpoints in the association uniquely identify that association.
Tech Stuff – SIGTRAN (SS7 over IP)
SCTP uses periodic heart-beat messages to confirm the status of each end point. Automatically reroutes traffic in the case of failure or congestion. A peer signaling process can be in an active or standby state. Problems, comments, suggestions, corrections including broken links or something to add? Allows for multiple virtual connections on the same physical line.
M3UA layer
View the status of the SCTP association by which the remote peer signaling process is reachable. Does not need SCCP services, reducing the complexity of the node and thereby reducing cost. If multiple protocol variants network definitions or multiple upper layers must be supported on the same M3UA instance same boardan NSAP tuhorial required for each SIO value and protocol variant.
