Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The embodiment of the present invention provides a data packet tracking method for the simulation verification of the switch system, such as figure 1 , figure 2 As shown, the method includes the following steps:

[0023] Step 1: Complete the identification of the key information of the data packet.

[0024] The key information of the data packet generally includes:

[0025] Stream ID (stream_id), which identifies which data stream the data packet belongs to;

[0026] Scenario ID (scenario_id), which identifies the serial number of the data packet in the corresponding data stream;

[0027] Data packet ID (data_id), the sequence number of the data packet generated by the stimulus generator, globally unique;

[0028] Copy ID (copy_id), for multicast and broadcast scenarios, data packets may be copied, and this ID identifies the seri...

Abstract

The invention discloses a data packet tracing method for simulation verification of a switch system. The data packet tracing method comprises the following steps: a first step: identifying key information of a data packet; a second step: adding the key information of the data packet in an excitation generator (generator) during simulation; a third step: collecting, refreshing and outputting the key information of the data packet to a text at a key node; and a fourth step: using a command of the data packet tracing method to seek out the data packet or path information of corresponding cells according to a certain key information combination. According to the data packet tracing method disclosed by the invention, the key information of the data packet is identified, and the data packet is searched by the key information, so that the track of the data packet is open-and-shut, no level by level search is necessary, and the manpower cost of a positioning problem is saved by a one-key operation, so that the positioning efficiency of data packet loss or error and other problems is improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a data packet tracking method for simulation verification of a switch system. Background technique [0002] With the development of the communication industry, the development of switches is advancing by leaps and bounds, various protocol standards and switching schemes are becoming more and more complex, the switch system is becoming larger and larger, and the simulation test of the switch system is becoming more and more complicated. [0003] As the difficulty of emulation testing of switch system increases, there are more and more testing methods. For example, Chinese invention patent CN103440195A discloses a logic chip-based switch chip verification method and device, and introduces a method for emulating and verifying switch chips, which makes configuration use cases easier. For example, Chinese invention patent CN104253723A discloses a method and device for v...
