F or more information, see M3UA management function summary. Routing keys are defined using c ombinations of the following parameters: It performs these primary tasks:. Defined by RFC Both transport MTP3 messages. Routes messages to their IP destinations. Cannot support ISUP services. If you are happy it’s OK – but your browser is giving a less than optimal experience tuotrial our site.
For more information, see M3UA management function summary.
Automatically reroutes traffic in the case of failure futorial congestion. A standard IP layer. There is a one-to-one relationship between a peer server and a routing key. Does not need SCCP services, reducing the complexity of the node and thereby reducing cost.
SUA can enhance the efficiency of the network and provides a means for simpler implementations.
SG’s single function is to relay MTP3 messages. M3UA uses a flexible configuration capable of supporting a wide variety of network routing and addressing requirements.
Tech Stuff – SIGTRAN (SS7 over IP)
SG is an SS7 node with a point code. MTP3 routes the message back to the origination SP. Allows for messages to be delivered in the order in which there were sent. Peer servers can be local or remote.
Dialogic NaturalAccess SIGTRAN Stack Developer’s Reference Manual (): M3UA layer
SCTP’s multi-streaming allows data to be delivered turorial multiple, independent streams, so that if there is data loss in one stream, delivery will not be affected for the other streams. SG is not an SS7 node and has no point code. Messages are handled from point code to point code.
Maintains the availability status of all destinations through all routes.
A peer signaling process can be in an active or standby state. For more information, see M3UA service function summary.
SG tutoriak have upper SS7 layers, e. A single IP port number is used across the entire address list at an endpoint for a specific session. 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 thtorial peer signaling processes PSPs. Each NSAP is associated with a service indicator field and protocol variant combination.
Allows for multiple virtual connections on the same physical line. 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.
MTP3 routes from point code to point code. Interface to the higher and lower SS7 layers. SCTP uses periodic heart-beat messages to confirm the status of each end point. Each user application might be assigned its own stream virtual connection. The primitives are described in Q.
