Embodiment Construction

[0036] The technical solutions in the embodiments of the present invention will be described clearly and in detail below with reference to the drawings in the embodiments of the present invention. The described embodiments are only some of the embodiments of the invention.

[0037] The technical scheme that the present invention solves the problems of the technologies described above is:

[0038] In order to clearly and detailedly introduce the embodiment of the present invention, here first combined with figure 1 Briefly introduce some relevant knowledge in SDWN and explain the applicable application scenarios of the method of the present invention. Such as figure 1 As shown, the SDWN network architecture is divided into three layers, namely the application plane layer, the control plane layer and the data plane layer. In SDWN, in order to improve network programmability and improve network resource utilization, the data plane is virtualized. The method of the invention m...

Abstract

The invention claims to protect a data processing method for improving the performance of a virtualized network under SDWN, belonging to the field of communication technology. The IEEE 802.11 frame is intercepted at the MAC802.11 layer, and the IEEE 802.11 frame is decomposed according to the frame type for processing tasks, and manages the frame. , The ARP request frame in the data frame and the DHCP request frame in the data frame are sent to the user space for processing to complete the user's virtual access and IP address allocation; the control frame and data frame are processed separately in the kernel space, control The frame implements functions such as channel access control, and the data frame is sent to the enqueue processing thread module. According to the different types of data services, the data frame is buffered in the buffer queues with different priorities. In the data forwarding thread module, data packets in multiple buffer queues are forwarded through a scheduling algorithm based on service bandwidth allocation. The invention can reduce the data frame processing time delay and improve the data forwarding efficiency.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a data processing method for improving virtualized network performance under SDWN. Background technique [0002] SDWN is the English abbreviation of software defined wireless network (software defined wireless network), and it is an innovative application of SDN (software defined network) thought in the wireless field. SDWN simplifies the complexity of the network, abstracts the network to shield the complexity of the bottom layer, and then provides simple and efficient configuration and management for the upper layer. For the innovation and smooth evolution of WLAN, the introduction of SDWN brings advantages such as wireless network openness, virtualization, network function scalability, user selection and application awareness. In order to realize this flexible and controllable network in SDWN, software is generally used for control and forwarding. Software such as Click ...
