Abstract: The routing of traffic in wireless networks is performed in accordance with a routing metric. The routing metric can reflect the effects of future self-traffic of a forthcoming communication flow. In a described implementation, a routing decision is made for a forthcoming communication flow that is to propagate over multiple nodes of a multi-hop wireless network. The routing decision is based on at least one predicted effect on the wireless network from self-traffic of the forthcoming communication flow.

Abstract: Systems and methods for compressing markup language data, such as XML data, are provided that utilize a finite state machine (FSM), which is representative of an XML schema, and a rule file. Information defined in an XML schema is abstracted into a finite state machine (FSM). The rule file ensures that a compressor and de-compressor have consistent FSMs when the compressor and de-compressor for XML data are not in the same location, such as is generally the case for Web Services scenarios or other client/server scenarios. With the rule file, FSMs can thus be be easily stored, transmitted and updated.

Abstract: In view of the foregoing, the present invention provides a unified software framework or architecture for distributed coordination of wireless devices and radios, referred to as Layer 2.5 Software MAC (or ‘SoftMAC’), which resides between the standard 802.11 MAC layer (Layer 2) and IP layer (Layer 3) to regulate and control the amount of traffic (both real-time and “best effort”) delivered to 802.11 MAC DCF interfaces. The software based design can be ported to different OS platforms and systems and is capable of handling new hardware interfaces and MAC mechanisms (e.g., 802.11e) with only a software upgrade. The invention thus provides a natural way to make end systems support coordination of different radios of device(s), achieving better performance. Advantages of the 2.5 layer software MAC in accordance with the invention include: (a) there are no hardware constraints; (b) heterogeneous wireless/radio support is provided at the 2.

Abstract: A method provides differentiated quality of service (QoS) by providing adaptive updates to media access control (MAC) layer parameters on a distributed basis. The method includes calculating a failure probability for a transmission over the network, determining a target value for determining a contention window according to a mapped function of the failure probability, and altering the contention window according to a scaling function of the target value. The mapped function and the scaling can provide QoS differentiation. A wireless device ensures fairness in a wireless time slotted network and includes a network interface card (NIC), a network driver interface, a network monitor, a statistics engine, and an adaptive parameter engine for determining a target value for determining a contention window according to a mapped function of the one or more probabilities to enable an alteration of the contention window and provide new parameters for the MAC layer.

Abstract: A middle layer network protocol enhancement, virtual connectivity (VC) makes the network attachment point changes of local and remote peers transparent to applications that use network services. A virtual connectivity module local to each peer translates communication connection parameters from apparent to real and vice versa, as well as sending and receiving secure connection updates directly to and from peers. Unlike Mobile IP, no routing infrastructure modifications are required. A subscribe-notify service provides connection update notifications when direct peer-to-peer connection updates are not possible, for example, when two communicating peers move simultaneously or when the moving peer is communicating with a peer behind network address translation (NAT). Methods for detecting these conditions are disclosed, as is a virtual connectivity protocol and virtual connectivity module architecture.

Abstract: Systems and methods for Compound TCP are described. In one aspect, a single TCP connection is opened for communication of data over a compound stream between first and second computing devices. The compound stream includes two or more logical data streams to emulate congestion control behavior of multiple separate network (TCP) connections. Data flow over the compound stream is managed with multiple different congestion control schemes.

Abstract: A resource allocation of multiple compressed AV streams delivered over the Internet is disclosed that achieves end-to-end optimal quality through a multimedia streaming TCP-friendly transport (MSTFP) protocol that adaptively estimates the network bandwidth while smoothing the sending rate. Resources allocated dynamically according to a media encoding distortion and network degradation algorithm. A scheme is also disclosed for dynamically estimating the available network bandwidth for streaming of objects, such as MPEG4 multiple video objects, in conjunction with the MSTFP protocol. The scheme can account for packet-loss rates to minimize end-to-end distortion for media delivery.

Abstract: An implementation of a technology, described herein, for transmitting compressed network transport-layer-protocol headers in a speedy, efficient, inferentially synchronized, and robust manner. An implementation, described herein, models the transmission of compressed headers to the congestion procedure of the network transport-layer protocol (e.g., TCP's). Doing so, the sender of the compressed headers can infer whether the receiver correctly received them. Unlike the slow direct synchronization employed by conventional schemes, this implementation of the present claimed invention inferentially synchronizes by modeling after the congestion procedure of the network transport-layer protocol. This is inherently faster than direct synchronization. Since the implementation performs well over both noiseless and noisy links, it is particularly suited to use over wireless communications channels. This abstract itself is not intended to limit the scope of this patent.

Abstract: Overlay network peers may be grouped so that each peer in a peer group has a similar transport network proximity measure with respect to the peers in other peer groups. A first set of transport network distances may include distances between a peer group and peer group neighbors of the peer group. A second set of distances may include distances between a peer and the peer group neighbors of the peer group. The peer may decide to join the peer group if the first set of distances is near to the second set. A first peer group may query a second peer group for the second peer group's neighboring peer groups. The distance between the first peer group and each of the second peer group's neighbors may be measured. Overlay network connections may be established between the first peer group and the closest of the second peer group's neighbors.

Abstract: An end host in a peer-to-peer system stores identifiers for both its peers and the neighbors of its peers. When the IP address of the end host and one of the peers changes, the end host's new IP address can be sent to each neighbor of the peer so that communication between the end host and the peer will not be lost. The order in which the neighbors of the peer are stored can be prioritized for faster delivery of the end host's changed IP address to the peer. The prioritizing can be by available bandwidth of the neighbors, proximity of the neighbors, trust between the peer and its neighbors, the probability that the IP address of the neighbors will change, etc. Proximity of the peers from each other and the end host can be a function of the identifier, which can be generated from a public key.
