actually, it would be really helpful to the masses uf us who are being liberal with our delete keys if someone would summarize the two threads, comcast p2p management and 204/4.
240/4 has been summarized before: Look for email with "MLC Note" in subject. However, in future, MLC emails will contain "[admin]" in the subject. Interestingly, the content for the p2p threads boils down to: a) Original post by Sean Donelan: Allegation that p2p software "does not play well" with the rest of the network users - unlike TCP-based protocols which results in more or less fair bandwidth allocation, p2p software will monopolize upstream or downstream bandwidth unfairly, resulting in attempts by network operators to control such traffic. Followup by Steve Bellovin noting that if p2p software (like bt) uses tcp-based protocols, due to use of multiple tcp streams, fairness is achieved *between* BT clients, while being unfair to the rest of the network. No relevant discussion of this subject has commenced, which is troubling, as it is, without doubt, very important for network operations. b) Discussion started by Adrian Chadd whether p2p software is aware of network topology or congestion - without apparent answer, which leads me to guess that the answer is "no". c) Offtopic whining about filtering liability, MSO pricing, fairness, equality, end-user complaints about MSOs, filesharing of family photos, disk space provided by MSOs for web hosting. Note: if you find yourself to have posted something that was tossed into the category c) - please reconsider your posting habits. As usual, I apologise if I skipped over your post in this summary. -alex
