关于packet-switching编辑本段回目录
This is a temporary index for a collection of papers about packet-switching in the 1970s. I have deliberately excluded papers on ARPANET and CCITT X25 on the grounds that these systems have been adequately covered elsewhere. I have tried to choose papers which describe wide-area networks which were actually built and operated. I have excluded DECNET (aka DNA) on the grounds that it lacked a transport capability in 1980.
I may include papers on the Japanese DDX-1 system. I am still looking for technical papers on the following systems:
United Telecom before 1980;
Scannet from Norway
Centernet from Denmark
These papers date from the 70s when there were no standards for packet switching. For reasons explains in The Evolution of Packet Switching it was relatively easy to implement a network technology and provide better customer service at lower cost than with other technologies of the era. Proponents of both circuit switching and packet switching were active. Within the packet switching camp, there were sharp divisions between believers in datagrams and virtual circuits. ARPANET and CYCLADES are the most prominent examples of datagram technologies. RCP, TYMNET and X.25 are the best known virtual circuit systems.
This index begins with a group of survey papers which mention multiple networks. It is followed by papers describing specific networks. Most of these single network papers were written by people who were closely associated with the design or implementation of the subject network. The networks are listed in alphabetical order.
Lawrence Roberts was deeply involved in the creation of ARPANET due to his position as head of computer research at ARPA. He lists research efforts which led to the creation of ARPANET. Several other early packet-switching systems are briefly described. The economic and regulatory reasons which caused several other organizations to re-implement packet-switching are given. Prescient remarks about the future conclude the paper.
