Ipv6 header vs ipv4 header

Web8. You may as well ask why an ethernet header has an Ether Type field. The network stack needs to know which protocol in the next higher layer gets the payload of the current layer. Edit 1: The reason that each datagram has the protocol of the next upper layer is to create the layer independence. Each layer doesn't care what is in the payload ... WebCurrently IPv6 provides support for QoS marking via a field in the IPv6 header. Similar to the type of service (ToS) field in the IPv4 header, the traffic class field (8 bits) is available for use by originating nodes and/or forwarding routers to identify and distinguish between different classes or priorities of IPv6 packets.
