Estimating the term…
A communication network comprised of communication paths of server layers formed hierarchically by communication paths of client layers, wherein the state of control of the communication paths of a layer being controlled is independently managed in terms of both (i) an administrative state and (ii) a subordinate state indicating influence from communication paths of a server layer, the administrative state of the communication paths of the layer being controlled is changed according to the control for setting and releasing the communication paths, and the subordinate state of the communication paths of a client layer influenced by the change of the administrative state of the communication paths is changed accordingly. At this time, when a subordinate state has already been influenced by a state of control of the communication paths of a server layer, the processing for management is terminated.
A method of controlling communication paths in a communication network comprised of communication paths of client layers and communication paths of server layers comprised of these communication paths arranged hierarchically, comprising a process of:
A communication control system for controlling a communications network comprising communication paths of client layers and communication paths of server layers comprising those communication paths arranged hierarchically, provided with a trail control function unit for managing the communication paths of each layer by the administrative state and subordinate state, changing the administrative state of the communication paths due to control for setting and releasing the communication paths of the layer being controlled, and changing the subordinate state of the communication paths of a client layer which is changed by the change of the administrative state of the communication paths.
