What it is
The basic transfer unit in a packet-switched network, with no prior connection and no guaranteed order or delivery. The concept, developed for the French Cyclades network, directly influenced the design of the internet's IP protocol.
Developed by Louis Pouzin in the Cyclades network project (INRIA, Rocquencourt) in the early 1970s; its connectionless approach inspired Vint Cerf and Bob Kahn in designing TCP/IP.
What it led to
- the connectionless design of the Cyclades network
- direct influence on the internet's IP protocol (TCP/IP)
- modern network architectures based on independent packets
