Question

When transporting data from real-time applications, such as streaming audio and video, which field in the ipv6 header can be used to inform the routers and switches to maintain the same path for the packets in the same conversation?

Answer 1

The answer is flow label. This has the role of sending source to a unicast or multicast to meet its destination and that in order to function, it is in need of intervening routers in which it provides special handling.
