Objectives and Approach

The objective of the PROOF project is to provide interconnectivity between workstations and servers in a mixed ISDN and Ethernet LAN environment and to explore how existing applications might be affect by, and new applications could take advantage of, such interconnectivity.

The final demonstration would show applications running over OSI protocol stacks supported on workstations and servers directly attached both to LANs and to a digital PABX. High performance LAN interconnect would be shown with gateways operating between LANs and Primary Rate ISDN (PRI) on the PBX.

As the project evolved further objectives were added including some evaluation of true WAN usage and home working - the original ISDN PBX was replaced by use of switched Public ISDN connections, including Basic Rate (BRI) as well as PRI. New applications included multimedia and high quality video using an "inverse multiplexer" to aggregate sufficient ISDN bandwidth.

Results

The following techniques and capabilities were developed during the project:

Exploitation

A number of spin-off products were developed and introduced into the market place:
