Question

In IPv6, what field is used to indicate what sequence of packets from one source to one or multiple destinations a packet belongs to?​

Answer 1

Flow label

Step-by-step explanation:

The Flow Label field is one of the fields in the IPv6 header which signifies that it belongs to a particular series of packets from a source to a destination or multiple destinations, and requires intermediate IPv6 routers to handle them specially. The size of the flow label field is usually 20 bits. One of the main use of flow label is for delivery prioritization.
