title: List of defunct network processor companies
text: During the dot-com/internet bubble of the late 1990s and early 2000, the proliferation of many dot-com start-up companies created a secondary bubble in the telecommunications/computer networking infrastructure and telecommunications service provider markets. Venture capital and high tech companies rushed to build next generation infrastructure equipment for the expected explosion of internet traffic. As part of that investment fever, network processors were seen as a method of dealing with the desire for more network services and the ever-increasing data-rates of communication networks.
  
  It has been estimated that dozens of start-up companies were created in the race to build the processors that would be a component of the next generation telecommunications equipment. Once the internet investment bubble burst, the telecom network upgrade cycle was deferred for years (perhaps for a decade). As a result, the majority of these new companies went bankrupt.
  
  As of 2007, the only companies that are shipping network processors in sizeable volumes are Cisco Systems, Marvell, Freescale, Cavium Networks and AMCC.
