METHOD AND SYSTEM FOR PROVIDING INTRANET SERVICE BY CUSTOMER USING VIRTUAL NETWORKING TECHNOLOGY

摘要

The present invention relates to a method for providing an intranet service by client company using virtual networking technology. The method comprises the steps of: setting port isolation in an Ethernet switch located in a private network of a client company and a core switch located in a communication company service center; setting first VLAN ID information for identifying the client company in the Ethernet switch; setting second VLAN ID information for identifying a service provider in the core switch; and forming a virtual LAN communication network between the private network of the client company and the communication company service center by mapping the first and second VLAN ID information each other. Therefore, an independent VLAN communication network between the communication company and multiple client companies can be formed using P-VLAN technology.
