Since the high bandwidth and popular usage are the characteristics of cable network, it becomes one of the main solutions for residential network. The cable network is a kind of asymmetric bandwidth architecture, which generates certain performance issues. This article first discusses the issues stemmed from asymmetric bandwidth. It then briefly introduces Data over Cable Service Interface Specifications (DOCSIS) protocol, the most popular standard for cable network today. The rest of the article discusses the operations and mechanisms in DOCSIS protocol that solve those performance issues and other possible improvements in cable network.
