Problems solved by technology

However, with the rapid development of WLAN construction and application scale, the data flow that needs to be analyzed will increase rapidly. Due to the limited processing capacity of a single processing board, the analysis system must have the ability of parallel expansion to adapt to the rapid development of WLAN networks.

Embodiment Construction

[0026] First, introduce the technology adopted in the present invention, including the equalization algorithm according to interface type, the learning algorithm of MAC address and IP address, the equalization algorithm based on AP or user's IP address modulo, and the extraction and compression method of Capwap service data.

[0027] 1. The balancing algorithm according to the interface type refers to: load balancing according to the interface type of the access data. According to IP address, MAC address and protocol type, the data is divided into four types: AAA, Portal, Capwap and uplink port user service data, and distributed to different types of data processing boards.

[0028] 2. The learning algorithm of MAC address and IP address refers to: according to the identified AAA or Portal data, add the source or destination MAC address contained in the data packet to the MAC address table of the AC uplink port; according to the identified Capwap control Data, add the source o...

Abstract

The invention provides a load balancing method for bypass data of a WLAN (wireless local area network). The method is implemented through dividing data accessed by AC (alternating current) uplink and downlink port bypasses in the WLAN into four types of data, namely, AAA, Portal, Capwap and uplink port user data, according to IP addresses, MAC addresses and the protocol type; carrying out modulo operation on the high-flow uplink port user service data and distributing the data to a plurality of user service data processing boards according to the IP addresses of users; and carrying out extraction and compression on high-flow downlink port Capwap service data, then carrying out modulo operation on Capwap control data and service data according to the IP address of an AP, and distributing the data to a plurality of Capwap data processing boards. The method disclosed by the invention is applied to scenarios on which AC uplink and downlink port data in the WLAN is required to be subjected to bypass access analysis, thereby facilitating the parallel extension of a bypass access analysis system when the scale of the WLAN is progressively increased.

Description

technical field [0001] The invention belongs to the technical field of WLAN communication, and particularly relates to a load balancing method for bypassing data in a WLAN network. The method can send the large-flow data bypassed by the AC uplink and downlink ports to multiple data processing boards for processing, so that the split data can meet the subsequent analysis requirements and the processing capabilities of the processing boards, and facilitate the parallel expansion of the analysis system. Background technique [0002] WLAN networks will have problems such as signal coverage, co-channel interference, and hotspot overload. Simply relying on the network management information of each device cannot objectively and globally reflect the system operation, nor can it comprehensively present the key information of a single user's data passing through each device. The third-party WLAN data analysis system accesses the data of the AC uplink and downlink ports through the...
