Workshop Talks ISO and Wide Area Networks The talk deals with the current situation in WAN Networking in the UK and the plans for the transition from the current Coloured Book (CB) protocols to the emerging ISO protocols. The history of JANET (The Joint Academic Network) is described together with a description of the current position and a short resume of the coverage of the CB protocols on the machines in use in the Academic Community. This is followed by a comparision between the CB protocols and those emerging from ISO/CCITT. A description is then given of the plans now being made by the Academic Community to achieve a transition to the ISO protocols without the loss of major services or the creation of multiple non-communicating networks. Local Area Network Protocol Options This talk outlines the major options for open system working on Local Area Networks, with particular reference to 'Ethernet'. The various options currently under discussion within ISO will be highlighted coupled with a description of the work in progress within the Academic Community in the UK to produce or promote genuine multi-vendor, multi-system intercommunication.
