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. Figure 1 WebMar 24, 2024 · In IPv4, the header length is variable but in IPv6 it is fixed to 40 bytes. Optional functions have been moved to separate the extension headers. TTL is replaced by a hop limit. The checksum is not computed. On the way, routers do not fragment the packets as path MTU discovery is done by the originating router.
