摘要： A facility is provided for establishing a relatively low-speed path from a user desiring to access the well-known Internet and establishing a high-speed path from the Internet to the user so that the data speed accommodates both the user's requests and a response from an Internet web/host site. Moreover, a user may be mobile, in which case the low-speed path is a conventional wireless path. In most cases, a predetermined spectrum of frequencies, such as one or more television channels, is used as the high-speed path from Internet.

摘要： Techniques for performing rapid fault detection and recovery in communication networks are disclosed. For example, in one aspect of the invention, a technique for detecting one or more conditions in a communication network comprises the following steps/operations. One or more keep-alive packets are transmitted from a source node in the communication network to a destination node in the communication network over two or more paths between the source node and the destination node, wherein the two or more paths are at least partially disjoint. Upon receipt of the one or more keep-alive packets at the destination node via the two or more paths, at least one quality measure is computed at the destination node for each of the two or more paths, the at least one quality measure being indicative of one or more conditions in the communication network. While not limited thereto, the invention is particularly well-suited to Internet Protocol (IP) telephony networks, particularly those that provide Voice over IP (VoIP) applications.

摘要： A technique is disclosed that enables the adaptive pooling of M transmission paths that offer a first signal-quality guarantee, or no guarantee at all, with N transmission paths that offer a second signal-quality guarantee. Through this adaptive pooling, a telecommunications channel is created that meets the quality of service or waveform quality required for a packet stream being transmitted, while not excessively exceeding the required quality. The technique adaptively recaptures any excess signal quality from one path and uses it to boost the quality of an inferior path. A node of the illustrative embodiment selects the paths to handle a current segment of source packets, based on one or more parameters that are disclosed herein. The node adapts to changing conditions by adjusting the transmission characteristics for each successive segment of packets from the source packet stream.

摘要： A method is disclosed for conducting a search in which measurements of a time-varying property are made and updated during the search, and in which the measurements might be uncertain. In accordance with the illustrative embodiment, one or more search algorithm parameters (e.g., the maximum branching factor of a search tree, a depth cutoff for a search tree, a time cutoff, a threshold, etc.) are adjusted dynamically during the search based on at least one of: the degree of uncertainty of the measurements, the variability of measurements over time (e.g., standard deviation, etc.), and the fraction of members whose measurement is better than a threshold. In addition, the illustrative embodiment enables the search space to be pruned based on these criteria.

摘要： A technique is disclosed that evaluates a network path between (i) a first node in a first subnetwork of endpoint nodes, such as IP phones, and (ii) a second node in a second subnetwork. A “ricochet” node in the network path evaluates the path by probing one or both subnetworks, where the ricochet node acts as relay for traffic packets being transmitted between the two subnetworks. A given relay has only to probe a single, representative node within a subnetwork at any given time in order to obtain performance data that is representative of the subnetwork overall. By probing the representative node, the relay is able to acquire an assessment of network conditions that is valid for the path between the relay and any endpoint in the subnetwork. As a result, the disclosed technique reduces the probing overhead when many endpoint nodes on a given subnetwork are simultaneously active and experiencing adverse network conditions.
摘要翻译：公开了一种技术，其评估（i）端点节点的第一子网络中的第一节点（例如IP电话）和（ii）第二子网络中的第二节点之间的网络路径。网络路径中的“弹射”节点通过探测一个或两个子网络来评估路径，其中弹性节点用作在两个子网络之间传输的业务分组的中继。给定的中继只能在任何给定的时间探测子网内的单个代表性节点，以获得代表子网的性能数据。通过探测代表节点，中继器能够获取对于继电器和子网中的任何端点之间的路径有效的网络条件的评估。因此，所公开的技术减少了给定子网上的许多端点节点同时处于活动状态并且经历不利的网络条件时的探测开销。

摘要： A method and apparatus are disclosed for redirecting traffic associated with an application so that the traffic advantageously traverses (or “hairpins”) through an application-layer gateway. Because the present invention advantageously redirects traffic without any participation by routers, no changes to or replacement of routers in a network is required. The illustrative embodiment is disclosed in the context of Internet telephony, but is also applicable to other kinds of applications and types of communication (e.g., Internet Protocol Television [IPTV], instant messaging [IM], videoconferencing, etc.)

摘要： A method for estimating the network-layer topology of a telecommunications network is described. In particular, the illustrative embodiment of the present invention estimates the existence and connectivity of nodes in the topology based on the detection of network-wide end-to-end path intersections. This is based on the assumption that pairs of streams of packets that share a common node will interfere and that the interference can be detected in the received streams. In general, this interference is manifested as jitter. By transmitting streams on each pair of end-to-end paths in the network, and detecting interference (or a lack of interference) a matrix of path intersections for the network can be created. Using logic and supposition, the topology of the network can be estimated using the matrix of path intersections. Once the estimate of the topology is complete, the maintenance and operation of the network can proceed based on the topology.
摘要翻译：描述了用于估计电信网络的网络层拓扑的方法。特别地，本发明的说明性实施例基于网络范围端到端路径交叉点的检测来估计拓扑中节点的存在和连通性。这是基于共享公共节点的分组流对将干扰并且可以在接收的流中检测干扰的假设。一般来说，这种干扰表现为抖动。通过在网络中的每对端对端路径上发送流，并且检测干扰（或缺乏干扰），可以创建网络的路径交叉矩阵。使用逻辑和假设，可以使用路径交点的矩阵来估计网络的拓扑。拓扑结构的估计一旦完成，网络的维护和运行就可以根据拓扑结构进行。

摘要： Real-time hardware primitives are added to packet switches to provide efficient support for inward multicasting. The lookup table used for routing is extended by adding additional opcode and operand fields into the routing table and by including ALU circuitry to process these fields and corresponding fields in the arriving cells. Memory word widths can be extended with minimal additional chip count and the ALU can be a small addition in a header processing VLSI, thereby giving only a modest increase in complexity. By including real-time processing in the switch it is possible to solve the ACK implosion problem associated with high-speed reliable multicasting transport protocols. By keeping the primitives as general as possible, other applications can benefit as well from these real-time primitives.
