The DS field contains the 6-bit DSCP value. Explicit Congestion Notification (ECN) occupies the least-significant 2 bits of the IPv4 TOS field and IPv6 traffic class (TC) field. In theory, a network could have up to 64 different traffic classes using the 64 available DSCP values. See more Differentiated services or DiffServ is a computer networking architecture that specifies a mechanism for classifying and managing network traffic and providing quality of service (QoS) on modern IP networks. DiffServ … See more DiffServ is a coarse-grained, class-based mechanism for traffic management. In contrast, IntServ is a fine-grained, flow-based mechanism. DiffServ relies on a mechanism to … See more Under DiffServ, all the policing and classifying are done at the boundaries between DiffServ domains.
