Per-hop behaviour
Policy and priority applied to a packet when traversing a network hop
From Wikipedia, the free encyclopedia
In computer networking, per-hop behaviour (PHB) is a term used in differentiated services (DiffServ) or Multiprotocol Label Switching (MPLS).[1] It defines the policy and priority applied to a packet when traversing a hop (such as a router) in a DiffServ network.
