METHOD AND SYSTEM FOR VIRTUALIZING NETWORK CARDS ON NETWORK PROCESSING PLATFORM

摘要

The present invention provides a system and method for virtualizing network cards on a network processing platform. The system comprises: a network card monitoring module, used for collecting basic information of physical network cards on a network processing platform, and monitoring states of the physical network cards; a user configuration interface, used for receiving customized logical network card configuration information, and sending the received logical network card configuration information to a function configuration module; the function configuration module, used for implementing a working mode required by the logical network card configuration information and notifying the working mode to a management and scheduling module and a data sending and receiving module; the management and scheduling module, used for parsing a notification received from the function configuration module, and scheduling hardware resources of a plurality of physical network cards on the network processing platform to perform virtualization configuration on the scheduled physical network cards; and the data sending and receiving module, used for establishing, according to the working mode of logical network cards and the virtualization configuration, a correspondence between the logical network cards and the physical network cards in a data sending and receiving process by means of a mapping table, and used for sending or receiving data.
