Abstract: A network device that includes a plurality of packet processing components may receive traffic associated with one or more services. The network device may store state information for each of the plurality of packet processing components, while the plurality of packet processing components are receiving the traffic. The state information may include state configuration information and/or internal storage information. The state information may be stored using a data structure that is internal to the network device and external to the packet processing component. The network device may detect an error that prevents the packet processing component from processing at least a portion of the traffic. The network device may execute, based on detecting the error that prevents the packet processing component from processing at least the portion of the traffic, a recovery procedure that uses the state information to reset the packet processing component to an operational state.

Abstract: A network device may identify a configuration of resources that are to support attachable line cards. The configuration may include a power supply configuration that is used to provide power to packet processing components that are supported by the line cards, and a resource distribution configuration indicating whether resources in the line cards are shared between the packet processing components. The network device may determine whether to modify a power state of a packet processing component based on whether one or more power modification conditions are satisfied. The network device may modify the power state of the packet processing component based on determining that the power modification condition is satisfied. The power state of the packet processing component may be able to be modified to a particular power state based on the configuration of resources.

Abstract: A network device may receive traffic to be processed by a routing component, and may determine temperatures of an ASIC and an HBM of the routing component at a first time. The network device may determine whether the temperature of the ASIC satisfies a first ASIC temperature threshold or a second ASIC temperature threshold, and may determine whether the temperature of the HBM satisfies a first HBM temperature threshold or a second HBM temperature threshold. The network device may selectively throttle processing of the traffic by a first quantity when the temperature of the ASIC satisfies the first ASIC temperature threshold or the temperature of the HBM satisfies the first HBM temperature threshold, or throttle the processing of the traffic by a second quantity when the temperature of the ASIC satisfies the second ASIC temperature threshold or the temperature of the HBM satisfies the second HBM temperature threshold.

Abstract: A network device may include a packet generator device implemented in hardware. The packet generator device may include a control component, a payload generation component, and an interface element to receive test packet generation information. The test packet generation information may include one or more control inputs, header data that is to be included in one or more test packets, and information regarding a data pattern that is to be included in payload data of the one or more test packets. The one or more control inputs, when provided to the control component, may cause the control component to control the payload generation component to generate the one or more test packets based on the header data and the information regarding the data pattern.
