Abstract: PROBLEM TO BE SOLVED: To provide a coordination proxy system executing object rendering by a distribution system by deciding on processing an object so that a request object can be adjusted to capability information proper to a requesting side at an intermediate computing node (proxy server). SOLUTION: Object rendering is carried out by proxy servers 110 to 112 on the basis of an object retrieved from content servers 120 and 121. When clients 130 and 131 output a request, the servers 110 to 112 receive the identifier of a client and constructs appropriate receiver hint information(RHI) to be included in an object request. When a request object passes in a network 101, any among the servers 110 to 112 executes complete or partial rendering on the basis of relevant RHI.

Abstract: A distributed object rendering method and system for a collaborative data network is disclosed. The data network, which may include the Internet, has attached computing nodes, including object requestor nodes, object source nodes, and intermediate nodes which may be proxy servers. The method can allow each participating proxy server to adapt to the dynamic load conditions of itself as well as proxies, as well as to dynamic traffic conditions in the data network. The determination of which proxy or set of proxies is to perform object rendering and caching is based on a distributed, collaborative method that is adopted among the proxies. The criteria for such a method can include the bandwidth and current load of the network links among proxies, and/or the respective CPU usage of the proxies. If an object rendering can be staged, e.g., different resolution rendering, it can be performed by more than one of the proxies. The determination of which proxy performs which stage of the multistage rendering can also be adaptive to the dynamic load conditions, as well as network conditions.
