Systems and methods for configuring a network to include redundant upstream connections using an upstream control protocol

摘要

A network includes a primary upstream node associated with a predetermined type of traffic, and a secondary upstream node that is associated with the predetermined type of traffic and is communicatively coupled to the primary upstream node. The network also includes a plurality of traffic nodes communicatively coupled to the primary upstream node and to the secondary upstream node, and each of the plurality of traffic nodes includes a plurality of ports. The primary upstream node is configured to transmit a plurality of periodic indicator messages to each of the plurality of traffic nodes and to the secondary upstream node indicating that the primary upstream node currently is operating as a master upstream node for the network with respect to the predetermined type of traffic. Moreover, for each of the plurality of traffic nodes, a port of the plurality of ports that receives a most recent one of the plurality of periodic indicator messages from the master upstream node is configured to operate as a master upstream port for the traffic node with respect to the predetermined type of traffic.
