From Experimental Packet Switching Services to e-business services

In early 1970´s British Post Office set its first plan for the establishment of a public digital data network. In parallel this approach was an investigation of the two switching methods: a) the circuit switching technique and b) the newly developed packet switching. In accord the “Experimental Packet Switched Service - EPSS” has been established. This was functionally separated from existing digital and telex networks. This type of approaches generated the idea for the development of a standardized protocol for the interconnection of separated networks. The protocol standardisation lead to the interconnection of different networks and this had a drastic impact on culture and business services globally.
