- P2P, by establishing many connections at once,
"games the system" to seize priority over other traffic and can degrade
time-sensitive applications, such as Voice over IP (VoIP) , running on
the same network
- P2P disrupts the expected duty cycle and balance
of upstream to downstream traffic, particularly degrading certain types
of networks (DSL, cable modem)
- Most P2P traffic consists of illegally
redistributed intellectual property, potentially exposing network
operators to liability
- P2P programs establish servers on users' machines
(often without their knowledge), usually inducing them to violate their
contracts with their ISPs
- P2P programs impose many times more of a traffic
burden on the network than do standard downloading protocols such as
FTP and HTTP
- P2P programs transfer content provider's costs to
the end user's ISP without permission or compensation -- and multiply
those costs in the process. (Bandwidth on an ISP's network can be 100x
as costly as bandwidth on a co-located server)
