Abstract

An address of an information object repository that should service a client request for an information object is returned in response to a request therefor. The address of the information object repository which is returned is selected according to specified performance metrics regardless of whether or not the information object repository maintains a local copy of the information object that is the client request. In some cases, the address of the information object repository is further selected according to an address of a client making the client request. Further, the address of the information object repository is selected from a number of addresses of information object repositories. The specified performance metrics may include one or more of an average delay from the information object repository to the client, average processing delays at the information object repository, reliability of a path from the information object repository to the client, available bandwidth in said path, and loads on the information object repository. In some cases, the information object repository may be instructed to obtain a copy of the information object after the address of the information object repository is returned in response to the request therefore.
