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.

Built-in test traffic generator

A router may be tested using a packet-based testing technique in which the test packets are generated by the router. In one implementation, a forwarding plane in a router may include a first component to process header information of packets to determine forwarding information, and a memory component to store payload data for the packets. A control plane of the router may generate test packets, insert the test packets into the forwarding plane, receive a second set of packets from the forwarding plane, analyze the second set of packets to determine whether the second set of packets correspond to the inserted plurality of test packets, and output, based on the analysis, test results, relating to the operation of the routing device.
