U.S. regulators are expected to vote on May 15 on a new set of "net neutrality" rules aimed at making certain that broadband providers do not slow down or block consumers' access to legal Internet content.

The rules from the Federal Communications Commission, which released its framework in February, are expected to ensure network operators disclose how they manage Internet traffic and do not block any content on the Web.

The proposed rules are also expected to allow Internet providers to negotiate agreements with content providers on delivery of traffic to users as long as the deals they strike are "commercially reasonable," according to an FCC spokesman.
