Abstract:
A routing system which is capable of designating an optimum route for a call connection request, the routing system comprising:a route information transmitting/receiving unit which exchanges standardized network route information of a local node with adjacent nodes thereof; a route information management unit which manages said standardized network route information as routing information; an event processing unit which manages statistical event information besides said standardized network route information, said event information being obtained by detecting and statistically processing events in the local node, and said statistical event information including events that affect quality of the route and/or convenience of the local node and/or adjacent nodes thereof; wherein said event processing unit includes one or more of a call connection no good (â€œNGâ€ ) event processing unit, a call release event processing unit, a line disconnecting event processing unit, a node-corresponding route information receiving event processing unit, and a node-corresponding route bandwidth shortage information receiving event processing unit; and a routing unit which designates an optimum route for said call connection request based on said routing information managed by said route information management unit and said statistical event information managed by said event processing unit.
