ABSTRACT:
A communication link manager for problem determination and recovery of a failing resource on a communication link segment in a data communication network. When a problem occurs on a link segment, the using node passes link event data to the communication link manager for analysis. The communication link manager interacts with a configuration data base to determine the physical configuration of the failing link segment and the controlling link connection subsystem manager. The communication link manager directs the appropriate link connection subsystem manager to initiate tests of the various link connection components on the link segment under its control. When the failing resource is identified, the communication link manager initiates the appropriate non-disruptive recovery procedure through the link connection subsystem manager and prompts the data link control to restart the line.
