Subsequent Packets

Subsequent Packets
After the candidate and enable packets have been identified and a shortcut, or flow cache, has
been established, subsequent packets are forwarded by the switch to the destination without the
use of the router. Because the MLS-SE has the capability to rewrite the frames, it can make the
necessary modifications and forward the frame directly to the destination host.
The MLS-SE caches the necessary information such as the source and destination IP addresses,
the source and destination MAC addresses, and the MLS-RP-related MAC addresses. Using this
information, the MLS-SE is then capable of identifying packets belonging to a specific flow,
rewriting the frame, and forwarding the packets to the proper destination
