Multi-VLAN Design over IPSec VPN for Campus Network

Multi-VLANs are now widely designed and deployed within the business and education sectors, to provide comfortable and secure network management. For each network, there are several applications installed, such as VoIP, Wireless Access Point, LAN, Server farm, IoT devices. Each VLAN design must be sufficiently safe and secure. This paper describes the VLAN design and implementation of multi-application between two campuses of Songkhla Rajabhat University. This research shows three benefits of Multi-VLAN design, first, it is a cost-effective way to deploy multiple types of applications, second, it increases protection and security, and third, it can also reduce the network administrators' management of maintaining and managing the network as a whole, even if the two campuses are far away and maintain data transmission efficiency.
