Abstract: In the method, communication is established between a mobile device and access points in a wireless local area network by first connecting to a first access point on a first channel. After the first connection is established, the method determines whether a second access point is available before disconnecting from the first connection. If a signal strength of the first connection drops below a signal strength threshold, the method second connects to the second access point on a second channel. The above-described method is an example of a make-before-break or soft handoff methodology.

Abstract: A method and apparatus for seamless roaming support for wireless networks is disclosed. The method includes broadcasting a request for a physical address of a default router related to a mobile unit; receiving the request at the default router; replying to the mobile unit; and creating an initial entry in a location table.

Abstract: A method and apparatus for accessing a CDMA2000 network translate Internet (IP) addresses of wired and wireless out-of-network users in a source IP address of a single CDMA2000 account that is used for data communications with users of the CDMA2000 network by a group of the out-of-network users.

Abstract: 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.

Abstract: 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.

Abstract: In an arrangement that employs a push-pull paradigm, information that is to be communicated to clients is broadcast, or multicast, to cache servers, wherein the information is cached in preparation for its being pulled by clients. By pushing information to points close to the clients, both source overload and network overload are avoided. The pushed information in the disclosed approach is transmitted over Internet links, or over other communication channels, such as cable and radio systems. In operation, clients subscribe to specific services of the provider, an association is established between the subscribing client and a cache server, and the server informs the network that it should be included among the destinations to which information from the provider is transmitted. When information is subsequently transmitted by the provider and received by the cache servers, it is stored in the cache server in preparation for its being pulled by the clients, as desired and when desired.

Abstract: 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.
