    Abstract: Network packet tracing may be implemented on packet processors or other devices that perform packet processing. As network packets are received, a determination may be made as to whether tracing is enabled for the network packets. For those network packets with tracing enabled, trace information may be generated and the network packets modified to include the trace information such that forwarding decisions for the network packets ignore the trace information. Trace information indicate a packet processor as a location in a route traversed by the network packets and may include ingress and egress timestamps. Forwarding decisions may then be made and the network packets sent according to the forwarding decisions. Tracing may be enabled or disabled by packet processors for individual network packets. Trace information may also be truncated at a packet processor.

    Abstract: Methods and apparatus for transparent multipath utilization through encapsulation are disclosed. Respective encapsulation packets are generated for at least two different baseline packets transmitted between a source and destination linked by multiple network paths. Each encapsulation packet comprises contents of a corresponding baseline packet, and one or more data values selected in accordance with a path balancing policy. The data values added to one encapsulation packet may differ from those added to another. Different network paths to the destination may be selected for different encapsulation packets of a given transmission based at least in part on the added data values.

    Abstract translation: 公开了通过封装实现透明多路径利用的方法和装置。 针对由多个网络路径链接的源和目的地之间传输的至少两个不同的基线分组生成相应的封装分组。 每个封装分组包括相应基线分组的内容，以及根据路径平衡策略选择的一个或多个数据值。 添加到一个封装数据包的数据值可能与添加到另一封装数据包的数据值不同。 至少部分地基于所添加的数据值，可以为给定传输的不同封装分组选择到目的地的不同网络路径。

    Abstract: The following description is directed to configuring network devices. In one example, a deployed configuration for a network device can be collected. The deployed configuration can be representative of a state of the network device at the time of collection. A difference can be detected between the deployed configuration and an authoritative configuration for the network device. In response to detecting the difference, an update of the network device according to the authoritative configuration for the network device can be scheduled.

    Abstract: Techniques and solutions for distributing routing updates using timing information are described. For example, inter-device messaging protocols can support timing information (e.g., routing protocols be extended to support timing information). The timing information can comprise an indication of a time at which the routing update is to be put into effect. Using the timing information, a number of routing devices can put the routing update into effect at the same time (e.g., at an update reference time) according to a synchronous mode. Routing updates can be managed between routing devices that support timing information and routing devices that do not support timing information.
