WebDifferentiated services (DiffServ) is an IPv4 header field that is used to define the priority of each packet. The first 6 bits identify the value that is used by the QoS mechanism, and the last 2 bits identify the value that can be used to avoid packet dropping during network congestion. Traffic class is an IPv6 header field that is equivalent ...

WebFields in the IPv4 Packet Header. Significant fields in the IPv4 header include the following: Version – Contains a 4-bit binary value set to 0100 that identifies this as an IPv4 packet. Differentiated Services or DiffServ (DS) – Formerly called the type of service (ToS) field, the DS field is an 8-bit field used to determine the priority of each packet.
