ABSTRACT:
Delays are calculated for one or more virtual connections within a frame relay network. The delays may be calculated at periodic intervals for each virtual connection within the frame relay network so as to provide updated information about delays among the virtual connections. Each delay is calculated by sending a special delay measurement frame from an originating switch to a destination switch. The destination switch receives the frame and returns the frame to the originating switch. The time difference between when the frame was sent from the originating switch to when the frame is received back at the originating switch is calculated and designated as the delay value. A timestamp may be affixed to the frame to specify the time at which the frame is initially sent from the originating switch.
