    摘要: A method and system for caching objects and replacing cached objects in an object-transfer environment maintain a dynamic indicator (Pr(f)) for each cached object, with the dynamic indicator being responsive to the frequency of requests for the object and being indicative of the time of storing the cached object relative to storing other cached objects. In a preferred embodiment, the size of the object is also a factor in determining the dynamic indicator of the object. In the most preferred embodiment, the cost of obtaining the object is also a factor. A count of the frequency of requests and the use of the relative time of storage counterbalance each other with respect to maintaining a cached object in local cache. That is, a high frequency of requests favors maintaining the object in cache, but a long period of cache favors evicting the object. Thus, cache pollution is less likely to occur.

    摘要: A data access network system is described that includes a content server coupled to a plurality of proxy servers via an interconnect network. The content server store at least one content file. The data access network system also includes a system of maintaining content consistency between the content server and the proxy servers. The system includes a subscription manager in the content server that specifies all of the proxy servers that are subscribed to the content file. The system also includes a consistency manager that notifies all of the subscribed proxy servers that cache the content file to discard the cached content file from those proxy servers when the content file is updated in the content server. A method of maintaining content consistency between the content server and the proxy servers is also described.

    摘要: A cache system is described that includes a storage that is partitioned into a plurality of storage areas, each for storing one kind of objects received from remote sites and to be directed to target devices. The cache system further includes a cache manager coupled to the storage to cause objects to be stored in the corresponding storage areas of the storage. The cache manager causes cached objects in each of the storage areas to be replaced in accordance with one of a plurality of replacement policies, each being optimized for one kind of objects.

    摘要: A method for server consolidation is provided. The method includes collecting performance data of a plurality of source servers in a desired environment, selecting a group of one or more source servers from the plurality of source servers for consolidation, marking each source server in the with one of multiple usability statuses with one of such statuses indicates the marked source server is to be replaced or reused as necessary in the server consolidation, selecting a target platform for a new server, and performing a first server consolidation analysis of the first group based at least on the collected performance data, the initial usability status of each source server in the first group, and the first selected target platform.
