摘要： A wireless shared channel network packet communication method emulates fluid flow fair scheduling. Errors inherent in wireless communication and unaccounted for in fair scheduling for wired networks are accounted for according to the method. Lagging communication flows, typically caused by burst errors in wireless communication systems, make up for their lag by causing leading flows to give up their lead. The method is independent of the pattern of channel error. In a preferred embodiment, lag compensation is accounted for by a service tag which identifies a precedence for contention based upon the previous denial of access for channel error. This precedence allows compensation when channels become error free. A modified preferred embodiment first attempts intraframe compensation by swapping slots when a host predicts an error for its assigned slot and another host assigned a later slot is able to transmit in the slot. Interframe compensation, when needed, is accomplished preferably by a round robin contention among backlogged flows. Errors are predicted by hosts for a subsequent slot when activity is sensed in a current slot but no good packet is received. Preferred packet structures include data and control slots, with data slots partitioned to provide necessary error status and backlog information piggybacked with data so a base has sufficient information to implement compensation in contention resolution.

摘要： A hybrid Butterfly Cube (“BCube”) architecture is described herein. The BCube architecture is a server-centric network architectural design, and includes a plurality of servers. Each of the plurality of servers may have multiple network ports and serve not only as an end host, but also an intermediate relay node for other servers. The BCube architecture further includes a plurality of switches which are arranged in multiple levels. Each switch has a certain number of network ports for connecting to the servers. The BCube architecture provides multiple parallel paths between any two servers. A packet source routing protocol and a BCube source routing (BSR) protocol are used to determine which path is used for routing a packet between any two servers.

摘要： Described is a technology, such as implemented as social networking groupware application designed for mobile device users, that provides a data mashup service for various data types, including location dependent and mobility-aware data such as GPS location and surrounding maps. A mobile user may track the location and maps of roaming friends at runtime. To this end, a client device joins a squad of client devices that are each capable of communicating with one another over a wireless local area network (WLAN) connection. When in a squad, the client can obtain data for use as mashup information from other client devices in the squad over the WLAN connection (inter-squad). This may include intra-squad data that was obtained from a service based on information that the service received from another squad, e.g., over a WWAN connection.
