itwbennett writes "The IEEE has formed a group to assess demand for a faster form of Ethernet, taking the first step toward what could become a Terabit Ethernet standard. 'We all contacted people privately' around 2005 to gauge the need for a faster specification, said John D'Ambrosia, chairman of the new ad hoc group. 'We only got, like, seven data points.' Disagreement about speeds complicated the process of developing the current standard, called 802.3ab. Though carriers and aggregation switch vendors agreed the IEEE should pursue a 100Gbps speed, server vendors said they wouldn't need adapters that fast until years later. They wanted a 40Gbps standard, and it emerged later that there was also some demand for 40Gbps among switch makers, D'Ambrosia said. 'I don't want to get blindsided by not understanding bandwidth trends again.'"
