Abstract:
1. A method of determining timers for use by an HDLC Traffic Manager (HTM) state machine in an optical communication network, the method comprising: sending from a first node a first packet having a delay measurement byte to a second node that is on a link between the first node and the second node; receiving a second packet with the delay measurement byte from the second node, the delay measurement byte being adjusted by the second node to indicate its receipt by the second node; determining a measured delay value between a time of sending the first packet to the second node and receiving the second packet from the second node, the measured delay value being determined by hardware of the first node; and setting timer values of the HTM state machine based on the determined measured delay value wherein a first timer is computed as 2 times the sum of the measured delay value and 15 milliseconds.
