Abstract
A network includes an edge node configured to define per hop behaviors using a set of bits in an Ethernet header of a frame and a core node configured to receive the frame and to forward the frame according to the per-hop-behaviors. The network can also include a defined set of differentiated service classes, each differentiated service class associated with the set of per hop behaviors, indicated in the set of priority bits. The network classifies the Ethernet frame based on at least one of a set of priority bits or information in at least one protocol layer in the frame header of the Ethernet frame and determines a per hop behavior based on the classification.
