Abstract
A network device selects at least one other network device as its backup and communicates information for use by the backup network device(s) in assuming the role of the network device upon its unavailability. The network device also receives information from at least one network device that has selected it as its backup device for use in assuming the role of the selecting device(s) upon unavailability of the selecting device(s). Each network device may act as a backup for the same number of devices as it has backups. Selection of backup devices may be based on device reliability. In one embodiment, each network device has a primary and secondary backup. The primary backup assumes the role of the network device when the latter becomes unavailable, and the secondary backup assumes the role of the network device when both the network device and its primary backup are unavailable.
