The Federal Communications Commission (FCC) is expected to detail a new proposal today that will feature rules for how Internet service providers manage and route traffic on their networks.

The proposal, which is expected to advance with three out of five votes from the FCC, will be announced by FCC Chairman Julius Genachowski (pictured) and is likely to include two new guidelines for dictating how companies like AT&T, Verizon, Comcast and Charter Communications treat different packets and applications on their networks.

The Washington Post reports that the FCC is expected to vote on the new rules in October, possibly culminating in a final rule in the spring of 2010.

An FCC source told the paper:
 

Be they entrepreneurs or innovators or consumers or less powerful voices, a principle on transparency is about knowing how large carriers manage traffic on networks and understanding how their content will be treated ahead of time so no one is surprised. So a CTO of a fledging start-up isn't shocked when a new product that got angel investment won't actually work on the Time Warner system, for example.
