Distributed Hypermedia Link Service on WAN: An Experiment with MHEG on the ATM network
The concept of separating hypertext facilities from data storage and from presentation applications is now well established. The idea of hypertext facilities, known as link service, has been proposed and implemented on local area network by many [4,19,20,21,22,23].
In this paper we describe an architecture and implementation that extend the link service concept to the wide area network. The proposed architecture defines a hypermedia protocol and uses the MHEG standard as a common information representation and exchange format.
We address the majors issues such as data exchange of node contents and open access to hypermedia facilities. In the implementation, all MHEG compatible stations will have access to hypermedia link servers to manage hyper objects, and to content servers to retrieve content objects with the requested quality of service.
