Routing and congestion control in common channel Signaling System No. 7

Article Abstract:

A specialized packet switching network for transporting call control messages of telecommunications networks is provided by the Common Channel Signaling System 7 (SS7) protocol. There are two differences between specialized packet networks and classical packet switched networks: a high level of reliability and high performance for large volume of offered traffic. The SS7 protocol provides high performance while maintaining robustness during failures and changing conditions. The unique traffic and route handling as well as management aspects of SS7 are discussed. The provisions in the layers of the protocol that apply to signaling networks are illustrated and discussed. Signaling network performance related to routing and congestion control are also discussed. A list of acronyms is presented.

An overview of Signaling System No. 7

Article Abstract:

Signaling provides the distinct control infrastructure in modern telecommunication networks that is the basis of all other services. The access signaling component of signaling systems controls the provision of services between the user and the network. The network signaling component controls provision of services within the network or between networks. Access signaling structures provide point-to-point connections between the user and a network node. Network signaling structures provide network-wide communication between the nodes of public networks. The network signaling system acts as a traffic collector and distributor for access signaling tributaries. An overview of network signaling systems based on the Signaling System 7 (SS7) international standard is presented.
