Embodiment Construction

[0020] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] figure 1 Describes the Xilinx peripheral hardware board structure for network testing. The hardware part completes the connection between the virtual simulation network and the test equipment in the whole system, and uses FPGA and peripheral chips to realize the interface from the virtual network to the actual network. The interface board includes two modules: an interface module 101 and a main control module 102, where the interface The FPGA realizes the function of deframing and framing the test data flow. The main control FPGA needs to control multiple peripheral interfaces to work together. The main control FPGA controls the interface FPGA through the interconnection signal line. The interconnection interface between 101 and 102 is the data interactive pathway. 102 is the control core of the entire hardware interface board, which controls an...

Abstract

The invention relates to the field of communication, wherein the embodiment of the invention discloses a test method of multi-layer protocol stack network equipment based on OPNET. The method comprises the following steps: a peripheral interface circuit of a network test equipment hardware edition; software interface design of a network test hardware; a protocol extension test method; a multi-layer protocol stack conversion method, data stream encapsulation and binary bit mapping process; and hardware protocol test with segmentation function; and a test method of Web application type based ona struct frame and interface design. The method provides the peripheral test interface with commercial mature OPNET network simulation software, communicates a hardware interface plate with real network equipment, tests protocol overhead and protocol work flow, etc. By using the OPNET simulation software, the method realizes the test requirement of the network and the hardware, analyzes various critical issues currently existed in the multi-layer protocol stack and gives a complete solving method, and improves the reliability for testing the hardware equipment by means of network simulation. The method can solve the problems of the simplification of the test network hardware equipment and the lack of the simulation performance of the real network, and gives the interface design method withhigher expansibility and commonality.

Description

technical field [0001] The invention relates to the communication field, in particular to an OPNET-based multi-layer protocol stack network equipment testing method. Background technique [0002] With the rapid development of the network, there are more and more types of network equipment, such as switches, routers, hubs, bridges, gateways, etc., including different brands and models of equipment and equipment from different manufacturers. Due to the lack of general specifications, Some devices that are not clearly specified by the network protocol have different implementation methods, and the premise of network device testing is to place the device in the network. Usually the change of the test network will affect the results of the test data, and it is not worth the loss to build a test network for testing a device. The bridge can realize the protocol conversion of the data link layer between two network segments, the gateway is the conversion between the application lay...
