摘要： A method that seeks to provide a satisfactory quality of service for a stream of packets through a network. The illustrative embodiment of the present invention seeks to provide a satisfactory quality of service for a stream of packets by periodically or sporadically evaluating one or more alternative paths through the network and by sending the packets through a path with an acceptable quality of service. Normally, neither the source node nor any other node in a packet's path controls its route after it has left the node. In contrast, the illustrative embodiment of the present invention has the capability to affect the packet's path through the network by sending the packet to an intermediate or “ricochet” node in the network, which forwards the packet to the destination node. In effect, the source node can, if it deems appropriate, ricochet the packet off of the intermediate node rather than allowing the packet to take its normal direct path through the network.
摘要翻译：一种寻求通过网络为数据包流提供令人满意的服务质量的方法。本发明的说明性实施例旨在通过周期性地或偶尔地评估通过网络的一个或多个替代路径以及通过具有可接受的服务质量的路径发送分组来为分组流提供令人满意的服务质量。通常，分组路径中的源节点和任何其他节点都不会在离开节点后控制其路由。相比之下，本发明的说明性实施例具有通过将分组发送到网络中的中间或“弹射”节点来影响分组通过网络的路径的能力，该节点将分组转发到目的地节点。实际上，如果源节点认为合适，则可以使分组从中间节点跳出，而不是允许分组采用其通过网络的正常直接路径。

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 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.
摘要翻译：公开了一种方法和装置，其尝试提高在一个或多个路径上的分组流传输期间经历的服务质量。具体地，发送节点将数据源（例如，音频，视频等）编码成一个或多个子流，并将这些子流分配到多个网络传输路径上。根据本发明的说明性实施例，发送节点评估不能提供服务质量保证的第一网络路径的服务质量。当第一网络路径的服务质量不能令人满意时，调整在第二网络路径上发送的一个或多个子流的编码。换句话说，响应于第一信道上的变化条件来调整第二信道上的编码。

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 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 technique is disclosed that enables telecommunications endpoints to conveniently share the addressing information—that is, the Uniform Resource Identifiers (URI)—of documents that are available on the World Wide Web. In particular, a server is used to provide a bookmark service. The server acts as a repository of tag-URI pairs, in which each tag functions as a shorthand label for the corresponding URI. In the disclosed technique, a first user creates the tag for the intended URI by assigning a keyword to represent the URI as part of a bookmark tag-URI pair that the server stores. The created tag is presumably shorter than the URI that it represents, making the tag more convenient to use. A second user is then able to retrieve and use the URI by specifying the tag to the bookmark server. In essence, the technique of the illustrative embodiment enables the sharing of Web documents by sharing the bookmarks to those documents.

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： An apparatus and method are disclosed that enable a first telecommunications endpoint to ensure that a second endpoint is receiving the first endpoint's packet stream transmissions with a satisfactory waveform quality. When the second endpoint receives the packet stream, it decodes the media waveform from the stream, encodes the waveform back into a second packet stream, and transmits some or all of the packets in the second stream back to the first endpoint. The first endpoint then decodes the received waveform in the second stream and compares it to the original waveform transmitted to the second endpoint. Based on the comparison, the first endpoint adjusts the value of a quality indication, and provides the quality indication to its user and to the second endpoint. Advantageously, the user at the second endpoint is able to determine whether the received waveform is, in fact, close enough to the waveform that the first endpoint's user intended to be received and understood.
摘要翻译：公开了一种能够使第一电信端点确保第二端点以令人满意的波形质量接收第一端点的分组流传输的装置和方法。当第二端点接收到分组流时，它从流解码媒体波形，将波形编码回第二分组流，并将第二流中的一些或全部分组发回到第一端点。然后，第一端点对第二流中的接收波形进行解码，并将其与发送到第二端点的原始波形进行比较。基于比较，第一端点调整质量指示的值，并向其用户和第二端点提供质量指示。有利地，第二端点处的用户能够确定接收到的波形实际上是否足够接近第一端点的用户意图被接收和理解的波形。

摘要： A technique that seeks to direct and re-direct streams of packets through a packet network without adversely affecting the quality of service of existing streams is disclosed. In accordance with the illustrative embodiment of the present invention, streams of packets that are directed and re-directed through a packet network are initially put on probation. During the probation period, a quality-of-service measure for the stream is compared with a threshold whose value is initially high and decreases with time. This has the advantageous affect of noticing problems quickly so that they can be remediated quickly.
