Abstract: A computer system monitors connectivity between a core network and two or more paths comprising a contiguous local area network segment. Each of the two or more paths couple at least one member of a team of network resources of the computer system to the core network. Each of the members of the team is configured to receive network management frames transmitted by one or more devices residing near or within the core network. A break in the connectivity between a path of the network segment and the core network is detected whenever the at least one member of the team coupled to that path fails to receive an expected one of the network management frames within a predetermined time period.
