摘要： An apparatus and method are disclosed for supporting a plurality of outstanding requests between a client and server in a network. If the server completes computation of a later request from a client before an earlier request, then the network protocol supports transmission of responses in an out-of-order manner to the client, thereby allowing a high degree of parallelism on the client and the server. The server buffers responses until receiving an implicit acknowledgement from the client.

摘要： A method, computer program product, and system for routing URL data object requests in a proxy server array. A URL data object request is received at one proxy server of the array while the desired URL data object resides in the local cache of another proxy server in the array. The receiving proxy server will deterministically identify the residing proxy server based on information residing thereon without resorting to expensive query-response transactions, such as those that occur in proxy server arrays using ICP. An array membership list containing array membership information is available at each and every proxy server and is used in conjunction with the URL as the information for identifying the correct proxy server where the URL data object resides. First, a deterministic hash value is computed for each proxy server name and the URL. Next, a combined hash value is computed that combines the URL hash value with each proxy server hash value. Finally, the proxy server with the highest “score” or combined hash value is identified as the proxy server where the desired URL data object should reside in local cache storage. Since the array membership list, the URL, and the hashing algorithm are the same at each proxy server, the same proxy server will be identified as having the URL data object regardless of which proxy server originally receives the URL data object request.

摘要： A file allocation and management system for a multi-user network environment is disclosed. At least one server and two or more clients are disposed along the network in communicating via a request/response transfer protocol. Files directed for shared usage among the clients along the network are stored at the server. Each client is adapted to communicate with the server through a plurality of identifier sockets, wherein a first identifier socket is configured for bi-directional communication and a second identifier socket is configured for unidirectional communications initiated by the server. Files normally stored at the server, under appropriate circumstances may be temporarily stored in an internal cache or other memory at each client location, when the file is in use.

摘要： a method and system for providing a dual namespace client is disclosed. The present invention provides support and compatibility to a filesystem of a client which may have multiple local namespaces. In an embodiment of the present invention where the client is a node supported by a network server, the client, by communicating with and querying the network server, is able to direct the server to follow the client's rules governing appropriate filesystem operations. The integrity of the names of the files or entries stored on the network server are maintained without requiring any modifications to the structure or operation of the server itself.

摘要： A method, computer program product, and system for migrating URL data objects in a proxy server array when an array member is removed, added, or temporarily unavailable. An array membership list containing array membership information is available at each proxy server in the array and at all enabled client that is used in conjunction with the URL as the information for identifying the correct proxy server where the URL data object resides. First, a deterministic hash value is computed for each proxy server name and the URL. Next, a combined hash value is computed that combines the URL hash value with each proxy server hash value. Finally, the proxy server with the highest “score” or combined hash value is identified as the proxy server where the desired URL data object should reside in local cache storage. Since the array membership list, the URL, and the hashing algorithm is the same at each proxy server or enabled client, the same proxy server will be identified as having the URL data object regardless of which proxy server originally receives or enabled client generates the URL data object request. The hashing algorithm is designed to automatically compensate for changes in the array membership list so that only the fewest amount of URL data objects will migrate from the local cache of one proxy server to another proxy server as a result of array membership changes.

摘要： A method, computer program product, and system for directly accessing URL data object requests in a proxy server array. A URL data object request is generated by an enabled client to request a URL data object that resides in the local cache of proxy server in an array of proxy servers configured as a distributed cache. The enabled client will deterministically identify the residing proxy server based on information residing thereon without resorting to expensive query-response transactions, such as those that occur in proxy server arrays using ICP, or routing the URL data object request through different proxy servers of the array. An array membership list containing array membership information is available at each and every proxy server as well as all enabled clients. This list is used in conjunction with the URL as the information for identifying the correct proxy server where the URL data object resides. First, a deterministic hash value is computed for each proxy server name and the URL. Next, a combined hash value is computed that combines the URL hash value with each proxy server hash value. Finally, the proxy server with the highest “score” or combined hash value is identified as the proxy server where the desired URL data object should reside in local cache storage. Since the array membership list, the URL, and the hashing algorithm are the same at all enabled clients, the same proxy server will be identified as having the URL data object regardless of which enabled client generated the URL data object request.
