Actually, unless there is near starvation issues, it shouldn't be a problem: If the traffic usage drops below 70% due to the lower priority view, I would expect it to bounce back up in the next epoch. If it doesn't, well, you are still >70% of listed capacity during your low priority time. Basically, "Square wave" the traffic doesn't help if the thershold is set at any value >50%, because either you will stay in low proirity (but still be sending >50%), or be bounced back up to high priority anyway. Thats one of the things I like about the scheme, both as a researcher and happy comcast customer: its very hard to game, but there is very little reason TO try to game it. _______________________________________________ alto mailing list [email protected] https://www.ietf.org/mailman/listinfo/alto
