How to Avoid SS 7 Network Outages

If in a real SS 7 network the signalling traffic load is low and bidirectionality and loop freeness of the routing data is assured by network planning and if sufficient links and routes are available to handle local failures, then local problems and congestion situations cannot spread within the network causing an SS 7 network outage. However, a high signalling traffic load, a nonfunctioning flow control and restart procedure, floods of signalling route management messages as well as a loss or delay of network management messages will lead to a spread of local problems within the network which may cause SS 7 network outages. Thus, in the case of high signalling traffic load, network reliability is normally not assured in real SS 7 networks.
