摘要： The invention comprises a method and apparatus for determining a network connectivity in a network having a plurality of nodes. In particular, one embodiment of the method includes generating a candidate link for each of a plurality of node pairs, predicting a performance of each candidate link by evaluating an expected impact of at least one condition on each candidate link, and determining the network topology using the predicted performances of the candidate links. The performance of each candidate link may be predicted by identifying at least one condition, determining the expected impact of the at least one condition on the candidate link, and predicting the performance of the candidate link by adjusting an expected performance of the candidate link using the expected impact of the at least one condition on the candidate link.

摘要： The present invention provides a method and apparatus for routing a data flow from a source node to a destination node in a mobile ad-hoc network (MANET). The present invention performs this function by first determining desired service requirements for an individual data flow to be forwarded to a destination node. Next, the present invention broadcasts an advertisement for each of the links in the MANET by the corresponding origination nodes, the advertisement including a value indicating the current performance level of the link. After broadcasting the advertisements, routing tables are composed at each of the nodes based upon the advertisements. Each routing table is constructed taking into account the advertised links and their corresponding values. After composing the routing tables, packets are forwarded toward their respective destinations by utilizing the routing tables in such a manner that the desired service requirements are satisfied.

摘要： The present invention provides a method and apparatus for routing a data flow from a source node to a destination node in a mobile ad-hoc network (MANET). The present invention performs this function by first determining a quantitative value for each link at an individual node in the MANET, where the value represents the current quality level of each of the links. Next, the present invention broadcasts an advertisement for each of the links in the MANET by each of the nodes, the advertisement including the value determined above. After broadcasting the advertisement, routing tables are composed at each of the nodes based upon the advertisements. Each routing table includes the value determined above. After composing the routing tables, a route based upon the routing table (and the link values contained therein) is selecting by the source node to direct the data flow to the destination node.

摘要： The present invention provides a method for obtaining and reporting performance information on node-to-node data transfers, i.e., network hops, based on integrated capabilities in Internet Protocol version 6 (IPv6), specifically extension headers. The performance of a (real-time) data flow is monitored between a source-destination pair by inserting specific information in an extension header of select data packets in the data flow. By initiating an extension header at a source client, and updating the extension header at any intermediate nodes along the source-destination path, a destination node can produce a detailed set of statistics relating to the current performance level of select nodes in a network based upon the reported data in the extension header. Additionally, data flow performance can be monitored on any desired network path or segment independent of particular flows on those paths.

摘要： The present invention provides a method for traffic engineering and fast protection of individual data flows using capabilities supported by IPv6. By utilizing IPv6 extension headers and flow labels a specific network route based upon quality of service (QoS) requirements of a data flow can be selected by a source node. Once a route meeting the QoS requirements of the data flow is selected, a source node can insert the route in an initial packet header and force the flow along the corresponding network path. The source and intermediate nodes cache the route and the flow label selected for a data flow. For subsequent packets, the flow label is used by intermediate nodes to determine the next hop along the route. In the event of a failure, an intermediate node can force the insertion of a new route (along with the original flow label) in the next packet belonging to the failed data flow so that, as the packet is forwarded toward the destination, intermediate nodes on this new path can cache the route and the corresponding flow label. This new route is then used to continue forwarding the data flow to the destination node.
摘要翻译：本发明提供一种流量工程方法，并且利用IPv6支持的能力快速保护各个数据流。通过利用IPv6扩展报头和流标签，可以由源节点选择基于数据流的服务质量（QoS）要求的特定网络路由。一旦选择了满足数据流的QoS要求的路由，源节点可以将路由插入到初始分组报头中，并强制流沿相应的网络路径。源节点和中间节点缓存为数据流选择的路由和流标签。对于后续数据包，中间节点使用流标签来确定沿路由的下一跳。在发生故障的情况下，中间节点可以强制将新路由（连同原始流标签）插入属于失败数据流的下一个分组，使得当分组被转发到目的地时，中间节点在这个新路径上可以缓存路由和相应的流标签。然后使用该新路由继续将数据流转发到目的地节点。

摘要： Techniques for network control of application states of applications associated with a communication device are presented herein. An application agent, associated with an application used by the communication device, controls transitioning the application between application states based on network indicators received or network events detected from a communication network. The application states include active state or doze state. An application management component associated with the communication network at least partially controls transitioning the application between application states to facilitate controlling network traffic or reducing network congestion. The application agent or application management component can map application states to various factors, including radio states, congestion level, application performance indicators, network policies, or user policies, to facilitate determining which application state to apply to an application at a given time. The application agent can be in a centralized location, or at a same or different location as the application source.

摘要： Roughly described, a packet switching fabric contains a separate queue scheduler for each combination of an input module and a fabric output port. The schedulers may also be specific to a single class of service. Each queue scheduler schedules its packets without regard to state of other input queues and without regard to packets destined for other output ports. In an aspect, the fabric manages per-flow bandwidth utilization of output port bandwidth capacity by monitoring the same and asserting backpressure toward the queue scheduler for any thread that is exceeding its bandwidth allocation. In another aspect, a switching fabric uses leaky buckets to apply backpressure in response to overutilization of downstream port capacity by particular subflows. In another aspect, a switching fabric includes a cascaded backpressure scheme.
