    • A technique triggers packing of path computation requests (PCRs) for traffic engineering (TE) label switched paths (LSPs) that are sent from one or more label-switched routers (LSRs) to a path computation element (PCE) of a computer network. According to the novel technique, incoming PCRs are packed into sets in response to a certain event, and one or more TE-LSPs (paths) are computed for each PCR of a particular set based on the PCRs of that set. Specifically, the PCE detects an event in the network (“network event”) indicating that an increase in the number of incoming PCRs has occurred, or that an increase is likely to occur due to, e.g., a change in a network element. Once the net-work event has been detected, the PCE packs the incoming PCRs into configured-length sets, such as, e.g., for a specified time interval or a certain number of PCRs. The PCE computes paths for each PCR of a particular set while considering the other PCRs of that set, thereby reducing race conditions, signaling overhead, and set-up failures.
    • 一种技术触发了从一个或多个标签交换路由器(LSR)发送到计算机网络的路径计算元件(PCE)的流量工程(TE)标签交换路径(LSP)的路径计算请求(PCR)的打包。 根据新技术,响应于某个事件将输入的PCR打包成集合,并且基于该集合的PCR针对特定集合的每个PCR计算一个或多个TE-LSP(路径)。 具体地,PCE检测网络中的事件(“网络事件”),其指示进入的PCR的数量的增加已经发生,或者由于例如网络元件的变化而可能发生增加。 一旦检测到网络工作事件,PCE将输入的PCR打包成配置长度的集合,诸如例如指定的时间间隔或一定数量的PCR。 PCE计算特定集合的每个PCR的路径,同时考虑该集合的其他PCR,从而减少竞争条件,信令开销和建立故障。

    • In one embodiment, a first ranging timing description describing at least a duration of time during which a subject cable modem (CM) may burst and a duration of time during which the subject CM and other CMs in a multiple access network are not permitted to burst is translated into a second ranging timing description describing a duration during which a burst from the subject CM is expected to be received by a cable modem termination system (CMTS). The CMTS is conditioned to receive a burst from the subject CM during the duration of time described by the second ranging timing description. A timing offset is determined from at least an actual time a burst from the subject CM is received by the CMTS and the duration of time during which the subject CM and other CMs in the multiple access network are not permitted to burst to produce a determined timing offset. The determined timing offset is reported to compensate for delay in the multiple access network and the subject CM.
    • 在一个实施例中,描述主题电缆调制解调器(CM)可以突发的至少一段持续时间的第一测距定时描述和多个接入网络中的主体CM和其他CM不允许突发的持续时间 被描述为描述来自主题CM的脉冲串期望由电缆调制解调器终端系统(CMTS)接收的持续时间的第二测距定时描述。 CMTS被调节为在由第二测距定时描述描述的持续时间期间从主题CM接收突发。 从CMTS接收到来自主题CM的突发的至少实际时间和多个接入网络中的主体CM和其他CM不允许突发以产生确定的定时的持续时间来确定定时偏移 抵消。 报告确定的定时偏移以补偿多址网络和对象CM中的延迟。
