X.25 Protocol A history of the X.25 Protocol Tim Elliott Morrisville State College Abstract X.25 is a Wide Area Network standard suite of protocols for packet switching developed by the International Telecommunication Union-Telecommunication Standardization Sector in the early 1970’s. It was designed to support traditional data networking over telephone wiring. Though widely used in the 1980’s, it has been largely replaced by newer IP standards such as frame relay. The purpose of this protocol

1) Compare and contrast the pre-1995 Lucent supply chain to the 1996-2000 supply chain with respect to the focus and structure of each. Identify what you believe to be the key factors that necessitated the changes that Lucent made. Did the changes make sense from a strategic perspective? In the pre 1995 Lucent’s supply chain, most of the Asian production was manufactured in Oklahoma City. The focus was on USA customers and business from Asia was not significant, therefore there were no manufacturing

to the launch of Spunik was to pour money into the research and development of high tech projects and the establishment of the Advanced Research Project Agency (ARPA). ARPA developed the ARPANET, computer-to-computer communication through packet switching networks. In 1969, the first “package switch” interface message processor allowed two computers to “talk” with each other. With this ability email was added in and dominated the traffic on the ARPANET. The addition of email created a dynamic
