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 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 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.

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.
