摘要： The notion of a "PTP aware" path is one current proposed approach to reduce asymmetry effects. In a fully PTP aware path there is the notion of on-path support mechanisms such as boundary clocks and transparent clocks at every switching or routing node. However, on-path support methods only address time-transfer errors introduced inside network elements and any asymmetry in the transmission medium, such as, for example, the fiber strands for the two directions of transmission, cannot be compensated for by on-path support mechanisms. Furthermore, in a real operational network, which may traverse different operational domains administered by different entities, full on-path support is a difficult challenge. In certain managed network scenarios full on-path support can be contemplated. Nevertheless, the universal asymmetry compensation method described herein mitigates the asymmetry in a network path, without requiring on-path support mechanisms such as transparent clocks and boundary clocks.
摘要翻译： “PTP意识”路径的概念是减少不对称效应的当前提出的一种方法。在完全PTP感知的路径中，存在路径支持机制的概念，例如每个交换或路由节点处的边界时钟和透明时钟。然而，路径上的支持方法仅仅解决在网元内部引入的时间传递错误，并且传输介质中的任何不对称性，例如用于两个传输方向的光纤线束，不能通过路径上的支持来补偿机制。此外，在可能跨越由不同实体管理的不同操作域的实际操作网络中，完全路径上的支持是一个难题。在某些托管网络情况下，可以考虑完整的路径支持。然而，这里描述的通用不对称补偿方法减轻了网络路径中的不对称性，而不需要诸如透明时钟和边界时钟之类的路径上的支持机制。

摘要： A method and apparatus for determining what level of performance must be maintained by a second communication service (910) so as to be perceived as being of equal quality to a first communication service, especially where the second communication service (910) is subject to additional impairments (972) not experienced by the first communication service. In one example embodiment, the present invention is applied to determining what combinations of packet loss rate (968) and packet delay are tolerable where a packet switched telephony service is desired to be perceived to be substantially equivalent to a traditional toll-quality non-packet switched telephone service. Empirically derived models (940) are used to relate user perception to objectively measurable characteristics, such as packet loss rate (968).

摘要： Methods and apparatus for providing layered gear mechanism to analyze network loss and latency conditions includes bundling data into data packets of varying depths, at a source with data packets of each depth belonging to a particular data type. The data packets of varying depths are transmitted in layers over a network, to a destination. Information for the transmitted data packets for each layer is collected constantly and analyzed as the data progresses along the network to identify corresponding network transmission characteristics. The transmission of subsequent data packets for anyone of the layers is adjusted based on the network transmission characteristics. The adjusting is repeated one or more times based on the analyzed information for the transmitted data packets. The transition metrics for each layer is utilized for relative analysis of transmission metrics across the layers to set the adjusting.

摘要： A method of determining frame loss between two management points (C, D) in an Ethernet network, in which the said management points each transmit frames to each other and each of the said two management points transmits in regular intervals to the other measurement messages which contain current counts of frames transmitted and received by the respective transmitting management point. At least one of the said two management points responds to a received management message to compute from counts of actual packets transmitted and/or received by a given one of the management points the frame loss at said given management point. At least one of the management points computes the said frame loss only once in a measurement interval which consists of a multiplicity of said regular intervals and employs in the computation the counts indicated by the measurement message most recently received by said one of the management points.

摘要： This invention comprises auto-diagnosis logic that can be implemented in operating systems in an appliance-like auto-diagnosis module coupled to the TCP receiver, the TCP sender or both. TCP events are sampled and a set of statistics on these events is maintained. Receiver side (205) TCP diagnostic techniques include detecting sender's re-transmission timeouts, evaluating the average size of packets being received (230), determining if a receiver is a bottleneck,and performing other evaluations (235) of an incoming data stream. Sender side diagnostic techniques include flagging transmission timeouts, monitoring the average size of a transmitted packet, evaluating if the advertised window accounts for the delay-bandwidth product of the network connecting the receiver and the sender systems, performing bottleneck checks, and other evaluations of an outgoing data stream. The results are aggregated using system attributes. Systems with common problem areas and attributes are grouped together. The TCP auto-diagnosis logic can be performed on-line or off-line.

摘要： A method and system (100) for optimizing routing traffic to a destination when multiple routes are available. A performance monitoring and inference component (102) measures the performance of the available paths to a large set of subnetworks, and uses those measurements to infer the performance of all available paths to an even larger set of subnetworks. A routing optimization component (104) uses a cost function that assigns a cost to a routing table based on information from component (102), and other path characteristics, and further uses a minimization methodology to find a routing table with a very low cost, as defined by the cost function. A BGP bridge (106) takes the routing table generated by optimization component (104) and communicates that information to the routers (116) using BGP, thereby ensuring that routers (116) will route traffic (108) in accordance with the routing table.
