VBN server clustering system, method of VBN server clustering, and VBN server for clustering

摘要

A visitor based network (VBN) server clustering system comprises a cluster of VBN servers for servicing a single local area network (LAN). Each VBN server comprises a client device data store for creating and maintaining device state records of user devices connected to the LAN, an interface for data communication with the user devices through the LAN, and a network traffic processing unit for processing network traffic from and to the user devices using the device state records in the client device data store. The VBN server further comprises a clustering manager for implementing clustering of the VBN servers by filtering the network traffic from and to the one or more user devices based on the configuration settings of the VBN servers and the device state records so as to allow the network traffic processing unit to process only a filtered portion of the network traffic. The filtering of the network traffic partitions the network traffic so that each user device is processed by a single one of the VBN servers within the cluster at a given time.
