Speaking for myself, I would suggest (a) getting your favorite ISPs to run a scavenger service (IP layer), and run DCCP over it (transport layer). DCCP has similarities to TCP in that it has a duplex connection and manages throughput; it differs from TCP in that it does no retransmission. The purpose of the window is to control the rate - like TCP, DCCP sends one window per RTT, but unlike TCP it discards any excess that the application might give it. Running UDP over a scavenger service, you fill a lot of pipes with traffic that will presumably be dropped later. Running DCCP, you drop that traffic in the first place. -----BEGIN PGP SIGNATURE----- iD8DBQFHaHY7bjEdbHIsm0MRAvx8AKClCufa15r7HIIO8fjf/u9a5iRiUwCfXtdE trtFbJah7LrnI2AvswVbb/Q= =qwzo -----END PGP SIGNATURE----- _______________________________________________ Ietf mailing list Ietf@ietf.org https://www1.ietf.org/mailman/listinfo/ietf
