Technical Field
The invention relates to a network communication technology, in particular to a method for self-sending a packet by a device under snakelike networking.
Background
In the environment test, the equipment is placed in a test box, the natural climate is simulated through the test box, and the related performance test is carried out on the equipment, so the sealing requirement is high. In the current environmental test, equipment is put into a test box, and then the equipment is connected to an external tester from the inside of the test box through an optical fiber or a network cable, so that the test box cannot be provided with a completely sealed space, a long optical fiber or a network cable has certain loss, and the result of the environmental test always generates a little deviation.
In the test process of the environmental test, generally, a snake-shaped networking mode is adopted to carry out performance test on the equipment, the snake-shaped networking mode is that a head physical port and a tail physical port are connected with a tester, every two middle physical ports are sequentially connected in pairs, and two ports which are not connected with each other are configured with forwarding services, so that data packets pass through all the physical ports.
The device-to-device autonomous packet function used herein is the RFC2544 protocol. The RFC2544 protocol is an international standard proposed by the RFC organization for evaluating network-connected devices (firewalls, IDS, Switch, etc.). The test under the RFC2544 standard mainly comprises the following steps: throughput, delay, packet loss, back-to-back. The method is characterized in that no external test equipment is needed during testing, and the generation and the check of the test frame are finished through own hardware and software.
