Originally, most Internet content was DownStream (DS) related and required an asymmetrical design of DS speed versus UpStream (US) speed. Most traffic was web-based downloads and e-mails, and very bursty in nature. Streaming content was added that caused average usage to increase. Peer-to-Peer (P2P) traffic created more US and DS requirements that made traffic patterns appear somewhat symmetrical. This paper explores the evolution of DOCSIS cable modem speeds and outlines some options available to provide greater speeds to combat competitive threats and to service the commercial market. One system in particular (Cablevision of Long Island) will be evaluated to explain how they approached this issue.
