Dropping random packets (i.e. FIFO queue, RED, not good on multiple-flows) Dropping a limited ratio of the packets is acceptable at least to me. Sending a TCP RST (i.e. most application protocols respond, easy for out-of-band devices) ... but terminating the connection is not. Spoofing packets is not something an ISP should do. Ever. Dropping and/or delaying packets, yes, spoofing, no. Changing IP headers (i.e. ECN bits, not implemented widely, requires inline device) These are all acceptable, where I think the adjust MSS is bordering on intrusion in customer traffic. An ISP should be in the market of forwarding packets, not changing them. -- Mikael Abrahamsson email: [email protected]
