    摘要: A protocol that provides assurance of consistent replication of objects from a server to caching servers, for example, over data communication networks such as the Internet. It is an application-layer protocol which guarantees delivery of objects such as files. This protocol insures that objects sent by a source machine such as a server to any number of destination machines such as caching servers actually arrive at the intended caching servers even when the caching servers are temporarily unavailable, for example, due to failure or network partition.

    摘要: The invention comprises a method and apparatus for establishing a persistent connection between a user device and a service gateway. Specifically, the method comprises obtaining state information in response to a connection request, establishing a connection between the user device and the service gateway using the state information, and maintaining the state information associated with the connection such that the connection is persistent through at least one network state change.

    摘要: A data streaming transmission method and system is disclosed having a network server connected to client device through a communication network with one or more of caching servers. The network server has a data streaming application and a memory for storing data. A series of connections, each using a data streaming arrangement, is formed in the path between the source network and client device by the caching servers. Each caching server can absorb network congestion in its downstream connection by utilizing an expandable buffer for storing additional segments of the streamed data and varying the transmission data rate in the down stream connection.

    摘要: A caching device comprises a disk cache that stores web objects. Each web object stored in disk cache is stored in contiguous storage space locations in the disk cache. Each pair of temporally successive web objects stored in the disk cache are stored in substantially sequential storage space locations in the disk cache.
