    摘要： A method for delivering resources to clients in a distributed computing environment. At least a first resource associated with a first content provider and maintained on an origin server references a second resource. The second resource is associated with a network formed by a plurality of repeater servers operable to serve the second resource to clients on behalf of the first content provider, the origin server being distinct from the plurality of repeater servers. Responsive to a request that causes the first resource to be served to a client from the origin server, at least one of the plurality of repeater servers is selected to serve the second resource to the client. If a copy of the second resource is available on the selected repeater server, the copy of the second resource is served to the client from the selected repeater server; otherwise, if a copy of the second resource is not available on the selected repeater server, the second resource is replicated on the selected repeater server.

    摘要： A method of managing information in a content-addressable computer system comprising a plurality of computers including at least a first computer and at least two second computers. The method includes creating a first identifier for a data item, at least in part, by hashing the content of the data item; sending a request including the first identifier from the first computer to the at least two second computers to access the data item, wherein at least one of the at least two second computers uses the first identifier to access the data item; and verifying that the content of the data item has not changed since the creation of the first identifier. 2. The method may include using the first identifier to locate a storage location for the data item on the computer system. The first identifier may be based on the entire content of the data item

    摘要： A plurality of data items are distributed across a plurality of computers, some of which may form a peer-to-peer network. A first computer receives a request for a data item from a requesting computer. The request includes a True Name of the data item. The first computer causes the requesting computer to obtain the data item from a second computer, distinct from the first computer. The first computer may not have a copy of the requested data item. The first computer may know the location of the data item. The first computer may forward the request for the data item to at least one other computer.

    摘要： A computer-implemented method operable in a computer system comprising a plurality of computers including at least a first computer and at least two second computers, the method includes: obtaining a first identifier from the first computer at the at least two second computers, said first identifier having been determined, at least in part, by applying a first function to the content of the data item, wherein the first function comprises a hash function; and at least one of the at least two second computers using the first identifier to ascertain a storage location for the data item on the computer system. At least one of the at least two second computers may use the first identifier to access the data item on the computer system. The method may include verifying that the content of the data item has not changed since creation of the first identifier.
