Method and apparatus for processing packet in IPv4/IPv6 combination network

摘要

In a method and apparatus for processing a packet in an IPv4/IPv6 combination network, packet overhead is minimized by identifying a tunnel session through a flow label field of an IPv6 header in a tunnel section when the packet is forwarded in a tunneling manner depending on a resource reservation protocol (RSVP) in the IPv4/IPv6 combination network.
