Abstract
A plurality of web servers (,, and,) have a common host name, and their authoritative domain server (,or,) responds to requests from a local domain-name server (,) for the network address corresponding to their common host name by making an estimate of the performance costs of adding a further client to each of the web servers and then sending the local domain-name server (,) the network address of the server to which the addition of a further client will result in the least performance cost. The performance cost is defined as the difference in the average number of waiting clients, and it takes into account both the additional response time for existing clients and the projected response time for the prospective new client.
