摘要： Methods that enable the detection and handling of lost messages during load-balancing routing protocols are disclosed. In accordance with the illustrative embodiment, when a candidate intermediate node N receives a routing-protocol message, node N performs: (1) a first procedure that is capable of detecting some lost routing-protocol messages that were previously transmitted by node N, and (2) a second procedure that is capable of detecting some lost routing-protocol messages that were previously transmitted by a neighbor of node N.

摘要： An apparatus and methods are disclosed that enable load-balancing of routes in ad-hoc wireless networks. In accordance with the illustrative embodiment, when a candidate intermediate node receives a routing-protocol message, the node waits before it transmits a message in response to the received message, where the amount of time that the node waits is based on the value of a load metric at the node and is independent of any other nodes in the network. As a result, a node that has a larger load will wait longer to transmit its routing-protocol message, and consequently, it is less likely that this node will be selected for inclusion in the new route. The techniques of the illustrative embodiment are applicable to both proactive and on-demand routing protocols, and are also applicable to other kinds of networks.
摘要翻译：公开了一种能够对ad-hoc无线网络中的路由进行负载平衡的装置和方法。根据说明性实施例，当候选中间节点接收到路由协议消息时，节点在响应于接收到的消息发送消息之前等待，其中节点等待的时间量基于a的值节点处的负载度量，并且与网络中的任何其他节点无关。因此，具有较大负载的节点将等待更长时间来传送其路由协议消息，因此不太可能选择该节点包含在新路由中。说明性实施例的技术可应用于主动和按需路由协议两者，并且也适用于其他种类的网络。

摘要： An apparatus and methods are disclosed that enable a non-multi-hop wireless terminal (i.e., a wireless terminal that has not been programmed to participate in multi-hop ad-hoc wireless networks) to in fact participate in a multi-hop ad-hoc wireless network, without any changes to the non-multi-hop terminal's software or hardware. In the illustrative embodiment, a wireless terminal T that already belongs to a multi-hop ad-hoc wireless network is assigned to a non-multi-hop wireless terminal W, and a signal is transmitted to terminal W that induces terminal W to use terminal T as a relay for transmitting messages. The assignment of multi-hop-capable terminals in the network to non-multi-hop terminals can be based on a variety of factors, such as signal strengths and the geo-locations of terminals.

摘要： Systems and methods for constructing and maintaining a peer-to-peer overlay graph are disclosed herein. The systems and methods include adding a node to the overlay graph. Adding the node includes choosing an edge that is not connected to the node, breaking the edge and connecting the node to broken edge nodes previously connected to the edge. The process is repeating if additional connections are need and node addition data is stored for the node.

摘要： A technique is disclosed that attempts to improve the evaluation of a network path's signal quality, as well as the selection of a network path for transmission purposes, without some of the costs and disadvantages of doing so in the prior art. In accordance with the illustrative embodiment, a node with access to the packet network, such as a VoIP telephone endpoint, evaluates the quality of service that is associated with each of multiple network paths. The evaluation process is iterative, in which the number of candidate paths is successively reduced from one iteration of the technique to the next. The multiple paths that remain as candidates in any given iteration are evaluated concurrently and at an evaluation bit rate that i) is less than the full transmission rate of the real-time traffic (VoIP) packets to be sent and ii) varies as a function of the number of candidate paths remaining under consideration.

摘要： A method and apparatus are disclosed that seek to improve the quality of service that is experienced during the transmission of a stream of packets across one or more paths. In particular, a transmitting node encodes a source stream of data (e.g., audio, video, etc.) into one or more sub-streams, and distributes those sub-streams onto multiple network transmission paths. In accordance with the illustrative embodiment of the present invention, the transmitting node evaluates the quality of service of a first network path that fails to provide a quality-of-service guarantee. When the quality of service of the first network path becomes unsatisfactory, the coding of one or more sub-streams that are being transmitted on a second network path is adjusted. In other words, the coding on a second channel is adjusted in response to the changing conditions on a first channel.

摘要： A method and apparatus are provided for authenticating the contents of a device requesting access to a first network, such as an enterprise network. If a device has connected to at least one other network then the content of the device is evaluated prior to obtaining access. The scope of the content evaluation may be based, for example, on properties of the other network or on one or more defined content authentication rules. If a device attempts to access a network, the content of the device is evaluated and the device may be restricted to accessing only one or more restoration services if the content fails to satisfy one or more predefined criteria, such as a content item that is out of date or a determination that the device connected to one or more external networks. The restoration service(s) can update a content item that is out of date, reinstall one or more programs or return configuration settings to default values.
