摘要： The present invention discloses a method and system for realizing Open vSwitch that supports 802.1p. The method comprises: a priority mode configuration stage: the switch receiving a priority configuration statement of a user and parsing the configuration statement; a configuration storage stage: storing the parsed configuration information into a switch database; and a priority-based data forwarding stage: the switch putting a received data packet into a corresponding priority queue according to said configuration information and a flow table so as to forward the data packet. The system comprises a configuration module, a configuration information storage module and a priority-based forwarding module, wherein the data priority-based forwarding module comprises a configuration reading unit, a traffic control setting unit, a flow table storage unit, a data packet parsing unit, a flow table matching unit, a flow table executing unit, a scheduling unit, priority queues, a sending unit, etc.

摘要： The present invention provides an AP handover method based on double wireless network interface cards. A mobile terminal actively scans the signal strength of an AP, compares the scanned signal strength with the signal strength of a currently accessed AP, and if the signal strength is greater than the signal strength of the current AP, starts handover; otherwise, continuously scans till the handover succeeds. To reduce the handover delay and in accordance with the characteristic that the moving paths are basically fixed in industrial application scenarios, the present invention provides a pre-learning mechanism, that is, before formal application, information such as the location of the AP and the handover sequence in the application scenario is learned and stored in a terminal node, so that specific scanning and handover can be implemented in formal application. The present invention solves the problem of rapid AP handover in the industrial mobile network scenario, the double wireless network interface cards are used to achieve handover without interruption, and the pre-learning mechanism is used in specific industrial application scenarios, so the scanning delay is further reduced.
