A device that converts from one protocol to another. For more information, see M3UA management function summary.

If multiple protocol variants network definitions or multiple upper layers must be supported on the same M3UA instance same boardan NSAP is required for each SIO value and protocol variant. Interface to the higher and lower SS7 layers. Each M3UA instance can support up to associations. Needs the SCCP services.

Allows for multiple virtual connections on the same physical line. Cannot support ISUP services.

Tech Stuff – SIGTRAN (SS7 over IP)

You could, at no charge, upgrade to a W3C standards compliant browser such as Firefox. Defined by RFC This interface is implemented with a set of messages that the application can pass to the M3UA layer on the TX 3mua processor.

MTP3 routes the message back to the origination SP. One address is designated as tutoriql primary address to receive data. Each IPSP must have its own point code. Routing keys are defined using c ombinations of the following parameters: A routing key defines the range of signaling traffic to be handled by a particular peer server.


There is a one-to-one relationship between a peer server and tytorial routing key. Each IP node is required to have a point code and an IP address. Routes messages to their IP destinations. Each IP node does not require a point code.

M3UA – Wikipedia

The SCTP user can specify at startup time the number of streams to be supported by the association. It performs these primary tasks:. For more information, see M3UA message handling.

Please take the time from a busy life to ‘mail us’ at top of screenthe webmaster below or info-support at zytrax. Does not need SCCP services, reducing the complexity of the node and thereby reducing cost.

A peer server PS is a logical entity on the IP network, such as a virtual switch or a database element, that is served by one or more peer signaling processes PSPs. Each user application might be assigned its own stream virtual connection.

MTP3 routes from point code to point code. Each peer server serves a specific routing key. Messages are handled from point code to point code. 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.

Automatically reroutes traffic in the case of failure or congestion. SCTP uses periodic heart-beat messages to confirm the status of each end point. Problems, comments, suggestions, corrections including broken links or something to add?

SG is not an Tuhorial node and has no point code. 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. Both transport MTP3 messages. Peer servers hutorial be local or remote. Legal and Privacy site by zytrax web-master at zytrax Page modified: Maintains the availability status of all destinations through all routes.

A standard IP layer. The IPSPs do not require point codes. The transport addresses used by the endpoints in the association uniquely identify that association.

View the tutorizl of the SCTP association by which the remote peer signaling process is reachable. SUA can enhance the efficiency of the network and provides a means for simpler implementations.

M3UA layer

You will have a warm inner glow for the rest of the day. Allows for messages to be delivered 3mua the order in which there were sent. F or more information, see M3UA management function summary. Each NSAP is associated with a service indicator field and protocol variant combination.

This local PSP is created automatically, not configured. The primitives are described in Q. A single IP port number is used across the entire address list at an endpoint for a specific session.

M3UA uses a flexible configuration capable of supporting a wide variety of network routing and addressing requirements.
