Comcast Cable is a large broadband Internet Service Provider (ISP), based in the U.S., serving the majority of its customers via cable modem technology. During the late part of 2008, and completing on December 31, 2008, Comcast deployed a new congestion management system across its entire network. This new system was developed in response to dissatisfaction in the Internet community as well as complaints to the U.S. Federal Communications Commission (FCC) regarding Comcast's old system, which targeted specific peer-to-peer (P2P) applications. This new congestion management system is protocol-agnostic, meaning that it does not examine or impact specific user applications or network protocols, which is perceived as a more fair system for managing network resources at limited times when congestion may occur.
