Abstract
Methods, apparatus and articles of manufacture for advertising network layer reachability information specifying a quality of service for a network flow are disclosed. Example network devices disclosed herein construct a packet filter based on a flow specification and a first quality of service advertised by a destination device for a first network flow, the packet filter to associate a default quality of service with a first incoming packet not associated with any of one or more advertised network flows represented in the packet filter. Disclosed example network devices also set, based on the packet filter, one or more bits of a second incoming packet that belongs to the first network flow to a value representative of the first quality of service. Disclosed example network devices further cause the second incoming packet to be routed towards the destination device based on the first quality of service.
