摘要： A method for routing a data request received by a caching system is described. The caching system includes a router and a cache, and the data request identifies a source platform, a destination platform, and requested data. Where the source and destination platforms correspond to an entry in a list automatically generated by the caching system, the data request is transmitted without determining whether the requested data are stored in the cache.

摘要： The invention is directed to techniques for managing access to data available from a data access device using a network switching protocol to manage content requests from clients. A data communications device receives a request for content from a client. The data communications device, such as a network switch, exchanges signals using the network switching protocol with one or more data access devices, such as a web cache. The data communications device can then select one data access device to provide the requested content to the client based, for example, on load balancing considerations. The data communications device sends a data transfer approval signal to the selected data access device. The selected data access device establishes a connection with the client using information, such as the client's network address, provided by the signals. The selected data access device then bypasses the data communications device and sends the requested content to the client. Using the network switching protocol, the data communications device can manage multiple, pipelined requests from the same client, while approving responses to the client from different data access devices, such as web caches and/or servers.

摘要： Methods and apparatus are described for intelligently for intelligently routing a request to a device (e.g., replica or server). A packet is received (e.g., by the client's gateway router) from a client, and the packet has a destination identifier associated with a server. When the packet is a start packet, a tag is added to the start packet to indicate that the start packet should be forwarded to any replica that duplicates the data content of the server. The destination identifier of the start packet is stored for later use. After storing the destination identifier of the start packet and tagging the start packet, the start packet is sent to the server. When the start packet has a tag indicating that the start packet should be forwarded to any replica that duplicates the data content of the server, the start packet is encapsulated and sent to each replica associated with the server. A replica device then receives a start packet sent from the client to the server. The start packet is encapsulated. The encapsulated start packet is cracked to determine the client's address. When the replica device is active and not busy, an immediate acknowledgement packet is sent to the client in response to the received start packet. When a first acknowledgement packet associated with the start packet is received (e.g., at the client gateway router), a source identifier of the first acknowledgement packet is stored and associated with the stored destination identifier of the start packet. After storing and associating the source identifier of the first acknowledgement packet, the first acknowledgement packet is sent to the client. Subsequent packets (e.g., after the start and acknowledgement packets) are then sent between the client and sender of the first acknowledgement packet.

摘要： A method for storing a plurality of multimedia objects in a cache memory is described. First ones of the multimedia objects are written into the cache memory sequentially from the beginning of the cache memory in the order in which they are received. When a first memory amount from a most recently stored one of the first multimedia objects to the end of the cache memory is insufficient to accommodate a new multimedia object, the new multimedia object is written from the beginning of the cache memory, thereby writing over a previously stored one of the first multimedia objects. Second ones of the multimedia objects are then written into the cache memory sequentially following the new multimedia object in the order in which they are received, thereby writing over the first ones of the multimedia objects. This cycle is repeated, thereby maintaining a substantially full cache memory.

摘要： Mechanisms and techniques provide a system that operates in a data communications device such as a switch or a router to provide a technique for load balancing packets between computer systems based on extra data inserted in the packets. The system receives a message containing extra data. The extra data was inserted into the message by a second data communications device existing in a network coupling the first data communications device to a first computerized device that originated the message. The system identifies, based on the extra data inserted into the message, a second computerized device that is to process the message and forwards the message to the second computerized device for processing. The extra data can include demographic data that can be used to select a demographic server, and for selection of a specific server from a group of servers associated with the demographic server.
