Embodiment Construction
[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0016] Such as figure 1 As shown, a kind of lightweight large-scale autonomous network protocol function testing method proposed by the present invention, its steps are:
[0017] S1: Implement the network interaction protocol based on the control plane code, realize the message forwarding function based on the data plane code, and then package the control plane code and data plane code into the container image;
[0018] S1.1: The quagga running in the container on the host machine acts as the control plane, runs multiple routing protocols, completes the routing information convergence and calculation of the entire network, and writes the autonomous protocols that need to be run in the cd / usr / local / etc directory (such as selfprotocol) configuration file selfprotocol.conf, start the protocol after configuring the file: zebra -d, selfp...

The invention relates to a lightweight large-scale autonomous network protocol function test method. The method comprises the following steps: constructing virtual router network element equipment byadopting lightweight virtualization software; wherein a network protocol application program is used as a control plane; a a user mode forwarding program serves as a data plane, each physical device can run multiple virtual router network element devices, network links between the virtual network element devices and network links between the virtual network element devices and entity devices are created according to a test topology, and a network topology similar to the test topology of the entity devices is formed. According to the invention, the requirement of large-scale network protocol test on the number of entity network equipment can be effectively reduced, and the resource consumption of the test server can be reduced.
Description
technical field [0001] The present invention mainly relates to the field of computer network protocol testing, and specifically refers to a lightweight large-scale autonomous network protocol function testing method, which is constructed by using lightweight virtualization technology (such as Docker) and user-mode protocol stack technology (such as Click) The virtual autonomous router network element performs network protocol function testing. Background technique [0002] Network emulator and network emulator are two tools that are mainly used when analyzing network performance. A network simulator is a software program that runs independently from the real network. It simulates the dynamic behavior of the real system by establishing a mathematical model of the real network system and following the same operating mechanism. Different from the network simulator, there is interaction between the network simulator and the real network. It builds a virtual network operating en...
