SYSTEM AND METHOD FOR MANAGING VIRTUAL LINK STATE

摘要

A system and method of managing virtual link state includes receiving, at a first device, a first status update associated with the virtual link from a second device. The first status update includes a first management status value (RM) and a first operational status value (RO). The system and method further includes determining a second management status value (LM) associated with the first device, determining a second operational status value (LO) based on the first status update and the RM, transmitting a second status update for the virtual link to the second device, the second status update including the LM and the LO, and determining a state of the virtual link based on the RM, the RO, the LM, and the LO. The first device is configured to be coupled to the second device using a physical network link partitioned into a plurality of first virtual links including the virtual link.

1. A method comprising:
receiving, at a first device, a first status update from a second device, the first status update providing status information for a physical link between the first device and the second device, the physical link being partitioned into a plurality of virtual links, the first status update including a respective first management status value and a respective first operational status value for each of the virtual links; determining a respective second management status value for each of the virtual links; determining a respective second operational status value for each of the virtual links based on the first status update and the respective second management status value; transmitting, by the first device, a second status update for the physical link to the second device, the second status update including the respective second management status value for each of the virtual links and the respective second operational status value for each of the virtual links; and determining a respective state of each of the virtual links based on the respective first management status value, the respective first operational status value, the respective second management status value, and the respective second operational status value; wherein:
the respective first management status value indicates a first desired state of a corresponding one of the virtual links from a perspective of the second device;the respective second management status value indicates a second desired state of the corresponding one of the virtual links from a perspective of the first device;the respective first operational status value indicates a first perceived state of the corresponding one of the virtual links from the perspective of the second device; andthe respective second operational status value indicates a second perceived state of the corresponding one of the virtual links from the perspective of the first device.
