By buffering at the remote end the packet can be forwarded promptly if approved, but protects downstream components if the traffic is malicious. Routing policies through the network are chosen according to initial estimates of the likelihood that a packet will be permitted to be forwarded from the downstream router, and of the time likely to be taken to reach a decision, allowing cache capacity requirements to be minimized by using higher-latency routes for packets unlikely to be forwarded promptly. |
