WebThe IP Differentiated Services Code Point (DSCP) The Internetwork Protocol (IP) [RFC791 has defined a best effort network layer service for connecting computers to form a computer network.This original specification defined an IP header field, known as the "Type of Service" (ToS).This field is now used to carry the DSCP and ECN fields. Webservice differentiation method has not yet been encountered. Whether Differentiated Services takes that role can not yet be decided. Differentiated Services is described in this work starting from more general level and proceeding more into detail. Most concentration is put on services and how they are supposed to be implemented and taken into use.

"WebThe Differentiated Service (DiffServ) is a network solution aimed at classifying the IP traffic flow [6] into traffic classes. It uses six bits, called DiffServ Code Point (DSCP), part of the eight-bit field called Type of Service (TOS) inside the IP header [7].Its goal is to determine the Per Hop Behavior (PHB) that defines the packet forwarding procedure of each node.
