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.

Allows for messages to be delivered in the order in which there were sent. A peer server PS is a logical entity on the IP network, such as a virtual switch or a database m3uq, that is served by one or more peer signaling processes PSPs. A peer signaling process can be in an active or standby state.

MTP3 routes from point code to point code. Allows for multiple virtual connections on the same physical line. M3UA uses a flexible configuration capable of supporting a wide variety of network routing and addressing requirements. The IPSPs do not require point codes.


SG is an SS7 node with a point code. SG is not an SS7 node and has no point code. This local PSP is mm3ua automatically, not configured. End-points exchange lists of addresses during initiation of the connection.

M3UA layer

For more information, see M3UA message handling. The whole IP network is represented by a single point code that addresses the MGC at the network edge. SUA can enhance the tuhorial of the network and provides a means for simpler implementations. Each peer server serves a specific routing key. Messages are handled from point code to point code.

MTP3 routes the message back to the origination SP. Interface to the higher and lower SS7 layers. One address is designated as the primary address to receive data.

Each IPSP must have its own point code. You will have a warm inner glow for the rest of the day. Both transport MTP3 messages. If you are happy it’s OK – but your browser is giving a less than optimal experience on our site. Does not need SCCP services, reducing the complexity of the node and thereby reducing cost.


Legal and Privacy site by zytrax web-master at zytrax Page modified: Routes messages to their IP destinations. Routing keys are defined using c ombinations of the following parameters: The primitives are described in Q. Automatically reroutes traffic in the case of failure or congestion. Peer servers can be local or remote. Please take the time from a busy life to ‘mail us’ at m3u of screenthe webmaster below or info-support at zytrax.

A routing key defines the range of signaling traffic to be handled by a particular peer server. Each user application might be assigned its own stream virtual connection. SCTP uses periodic heart-beat messages to confirm the status of each end point.

It is a ‘glue’ layer and its functionality is not defined by the standards.
