The whole IP network is represented by a single point code that addresses the MGC at the network edge. Each IP node does not require a point code. Each peer tutoril serves a specific routing key.

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.

MTP3 routes the message back to the tutoriap SP.

Each M3UA instance can support up to associations. A routing key defines the range of signaling traffic to be handled by a particular peer server.

Tech Stuff – SIGTRAN Introduction

You will have a warm inner glow for the rest yutorial the day. F or more information, see M3UA management function summary. SG is an SS7 node with a point code. If you are happy it’s OK – but your browser is giving a less than optimal experience on our site.

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. The primitives are described in Q. Automatically reroutes traffic in the case of failure or congestion. There is a one-to-one relationship between a peer server and a routing key. Each IPSP must have tutoriial own point code. MTP3 routes from point code to point code. For more information, see M3UA management function summary.


One address is designated as the primary address to receive data. A peer signaling process can be in an active or standby state. SG’s single function is to relay MTP3 messages.

SG can have upper SS7 layers, e. Messages are handled from point code to point code.

Tech Stuff – SIGTRAN (SS7 over IP)

SCTP uses periodic heart-beat messages to confirm the status of each end point. Each NSAP is associated with a service indicator field and protocol variant combination. Each IP node is required to have a point code and an IP address. Please take tutoriial time from a busy life to ‘mail us’ at top of screenthe webmaster below or info-support at zytrax.

Legal and Privacy site by zytrax web-master at zytrax Page modified: Maintains the availability status of all destinations through all routes. It is a ‘glue’ layer and its functionality is not tutorkal by the standards.

Dialogic NaturalAccess SIGTRAN Stack Developer’s Reference Manual (): M3UA layer

For more information, see M3UA service function summary. 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.

  DIN 41494 PDF

Defined by RFC Allows for multiple virtual connections on the same physical line. Each user application might be assigned its own stream virtual connection. A device that converts from one protocol to another.

You could, at no charge, upgrade to a W3C standards compliant browser such as Firefox. View the status of the SCTP association by which tutorisl remote peer signaling process is reachable. Problems, comments, suggestions, corrections including broken links or something to add? SUA can enhance the efficiency of the network and provides a means for simpler implementations.

M3UA layer

The transport addresses used by the endpoints in the association uniquely identify that association. Interface to the higher and lower SS7 layers. A standard IP layer. Routing keys are defined using c ombinations of the following parameters: The IPSPs do not require point codes.

It performs these primary tasks:. Does not need SCCP services, reducing the complexity of the node and thereby reducing cost. Both transport MTP3 messages. 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.
