I'd like to understand what can go wrong with these signals, and therefore what constraints we need to introduce. I would like to see a "threat" analysis that looks at the implications of "Forged, malicious trigtran reports" and also "erronous" reports taht do not reflect actual path status. Here's some first thoughts: Perhaps we could look at how these sort of things impact: 1) The network path from the reporting device to end host. i.e., the signalling cost itself. 2) The impact on the recipient - of retransmission, cwnd management, etc. 3) The rate/burst characteristics of the traffic on the network path from the sending end-host that arises after trigtran processing. It could be useful to look at scenarios which produce confusing indications: 1) Alternate paths - one reporting, one not.... 2) Effect of two reporting devicec, with differing path delay (possibly on the same path?) ... etc. Any ideas???
