Differentiated Services (DiffServ) Code Point

A Differentiated Services (DiffServ) Code Point is a marker in the header of each IP packet that prompts network routers to apply differentiated grades of service to various packet streams. It is specified by the DiffServ policy proposed by the IETF (Internet Engineering Task Force). This allows Internet and other IP-based network service providers to offer different levels of service to customers.
