Abstract

A gateway 10 receives a request from a client 930 and generates a request parcel containing the request and predetermined control information used to identify the request. Requests are placed in a store 20 which may be a FIFO buffer. A plurality of servers 920 each has an associated resolver 30 for requesting from the store a request parcel. Upon receipt of the request parcel the resolver extracts the request and passes it to the associated server for processing, and passes the control information to the gateway to enable data generated by the associated server to be routed to the client. Requests by resolvers for request parcels from the store may be made dependent upon the loading of the associated server. The resolver may provide a number of resolver threads, each thread being arranged to request a request parcel from the store. The number of threads is controlled according to the loading on the associated server.
