摘要： A network monitoring device may receive, from a mediation device, flow-tap content data (generated by the mediation device based on current and/or previous investigation reports associated with flow tapping) that needs to be monitored. The network monitoring device may map the content data to a flow-tap content destination address of a content destination device in an entry of a flow-tap content filter. The network monitoring device may analyze, using the flow-tap content filter, network traffic of the network to detect a traffic flow that includes the content data. The network monitoring device may generate, based on successfully detecting a traffic flow that includes the content data, a traffic flow copy and may provide the traffic flow copy to the flow-tap content destination address, wherein the traffic flow copy is to be accessible to the content destination device to enable a context analysis of the content data.

摘要： An example network device includes a memory configured to store a plurality of counts of packets of a data flow. The network device also includes one or more processors in communication with the memory. The one or more processors are configured to determine the plurality of counts of packets of the data flow, wherein each count of the plurality of counts includes a number of packets occurring in a predetermined time period. The one or more processors are configured to assign a corresponding range to each count of the plurality of counts, so as to assign a plurality of corresponding ranges. The one or more processors are also configured to determine a pattern in the plurality of corresponding ranges and send a number of active probe packets based on the determined pattern.

摘要： Using the ALTO Service, networking applications can request through the ALTO protocol information about the underlying network topology from the ISP or Content Provider. The ALTO Service provides information such as preferences of network resources with the goal of modifying network resource consumption patterns while maintaining or improving application performance. This document describes, in one example, an ALTO server that intersects network and cost maps for a first network with network and cost maps for a second network to generate a master cost map that includes one or more master cost entries that each represent a cost to traverse a network from an endpoint in the first network to an endpoint in the second network. Using the master cost map, a redirector may select a preferred node in the first network with which to service a content request received from a host in the second network.

摘要： An example method includes selecting, by a network device, a remote LFA next hop as an alternate next hop for forwarding network traffic from the network device to a destination, wherein the selected remote LFA next hop provides node protection to a primary next hop node on the shortest path from the network device to the destination. The method includes, for each candidate remote LFA next hop, performing a forward shortest path first (SPF) computation having the respective candidate remote LFA next hop as a root to compute a path segment between the respective candidate remote LFA next hop and the destination, wherein each of the candidate remote LFA next hops is the egress of a respective potential repair tunnel between the network device and candidate remote LFA next hop, and selecting the remote LFA next hop based at least in part on the computed path segments.

摘要： A power system includes a switch, a capacitor and a comparator circuit. The power system receives a signal to turn off power supplied to the power system, turns off the switch that is used to supply power to the system and discharges the capacitor. The power system also compares a voltage across the discharging capacitor to a threshold voltage value, and turns on the switch to allow power to be supplied to the power system when the compared voltage across the discharging capacitor equals the threshold voltage value.

摘要： An interface permitting users (i) to create a group (also referred to as a “source”) containing configuration statements and (ii) to direct the inheritance of that group's statements in the rest of the configuration information (also referred to as a “target”). The same group can be applied to different sections of the configuration information. Different sections of one group's configuration statements can be inherited in different places in the configuration information. Supporting such configuration groups allows users to create smaller, more logically constructed configuration files, thereby making it easier to configure and maintain data forwarding device software. For example, users can group together statements that are repeated in many places in the configuration, such as when configuring interfaces, and thereby limit updates to just the group. Users can also use wildcards in a configuration group to allow configuration information of the configuration group to be inherited by any object(s) in the target configuration that matches a wildcard expression.
