Network interface card fault injection methods and apparatuses

Abstract

The present invention provides a network interface card fault injection method. The method is characterized by comprising the steps of when a hypervisor loads a network interface card driver in a startup phase, invoking, by an interface of a network device in the hypervisor, a first interface implementation module of the network interface card driver; loading a fault injection module into the hypervisor in a fault injection mode; replacing the first interface implementation module of the network interface card driver with a second interface implementation module in the fault injection module, so as to enable the interface to invoke the second interface implementation module; acquiring a fault description instruction, and then sending the fault description instruction to the fault injection module, so as to enable the fault injection module to acquire a fault injection parameter carried in the fault description instruction; and when the interface of the network device invokes the second interface implementation module, injecting, by using the second interface implementation module, the fault injection parameter into a data package processed by network interface card hardware.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a network card fault injection method and device. Background technique [0002] Traditional telecommunication equipment adopts integrated software and hardware, and builds the operating system and application software on a dedicated hardware platform. The matching of software and hardware models is relatively fixed, and the scope of compatibility problems is limited. Design, development, and testing are aimed at certain software and hardware environments. The hardware quality is controlled by the same equipment manufacturer, so the system reliability is effectively guaranteed. [0003] With the establishment of telecom operators, they gradually focus on the research of network function virtualization (NFV), and take software and hardware decoupling, general computing, and hardware standardization as research goals. NFV is an emerging solution dedicated to improv...
