Authentication service cluster-based portal keep-alive system, method, authentication system and method

Abstract

The invention relates to a WLAN security access technology and discloses an authentication service cluster-based portal keep-alive system, method, authentication system and method. The objective of the invention is to solve a problem that a portal message cannot be normally sent to access control equipment due to inconsistency of access control equipment keep-alive and load portal service nodes. The portal keep-alive system of the invention includes access control equipment which continuously sends keep-alive messages carrying equipment serial numbers to a load balancer through NAT equipment, the NAT equipment which performs NAT conversion on source IP addresses and source ports in the keep-alive messages, transmits converted IP addresses and ports to the load balancer, and stores mapping relations of the IP addresses and port numbers before and after conversion, the load balancer which balances the keep-alive messages onto a certain portal service node, and the portal service node which stores the equipment serial numbers, the IP addresses and port numbers after the NAT conversion, and the correlation relationship of the IP address of the portal service node which receives the keep-alive messages after receiving the keep-alive messages. The systems and methods of the invention are suitable for portal authentication in enterprise authentication service clusters.

Description

technical field [0001] The present invention relates to WLAN security access technology, in particular to a Portal keep-alive system and method based on authentication service cluster, authentication system and method Background technique [0002] With the rapid development of network application technology, network information security issues have become increasingly prominent. At present, as an important technology and management method to solve network security problems, network access authentication technologies such as 802.1x (access control protocol for ports) authentication, PPPoE (point-to-point protocol over Ethernet) authentication, and Portal authentication have been rapidly popularized. Among them, Portal authentication has the advantages of simple operation, rich display effects, and convenient business promotion due to the use of web page login, so it is more and more widely used. [0003] The simplest Portal authentication system structure is as follows: fig...
