Abstract

Department of Transportation, Communication and Information of Manggarai Regency, is one of the instance of Regional Government of Manggarai, NTT, which is responsible to help the Head of Region concerning transportation, communication and information affairs. The lackness of human resources which was competent in computer networking, the high cost of VSAT IP Broadband internet service and maintenance cost of network’s backbone which is wireless based, have been becoming a problem to the Department concerning their main duties. As an impact, it is necessary to the Department to change their network’s backbone to wired network based, using VLAN. VLAN can divide network into several segments with low cost implementation. The using of VLAN Trunking Protocol (VTP) will ease the network administrator in managing VLAN. The VLAN design in this study used hierarchical model. The logical layer for data distributing was divided into two layers, core/distribution and access layer. Routing between VLANs used “router-on-a-stick using trunk” model, so that the workstations which were owned by different VLAN can communicate each other by using one router only. By using simulation method for testing the design, it was discovered that all workstations between different VLAN have been successfully connected each other and all servers were well-functioned.

Abstract

Servers are computers for computer center managers and the other. Many more client could make server have a hard woking. this situation will make the web serverperformance has decrease and making the access to the server will be difficulty because the server was busy or time-out. another problem is a down server or server failure. that is the problem that we must be avaoided. To overcome these problems, merging severalserversinto a single unitthat can worksimultaneouslyforload balancingserveris the solution. One method that is meaningful is using load balancing or even distribution of a burden ( request ) on the web server aims to relieve a burden is borne each server. In the process load balancing any one kind of load balancer is HAProxy, HAProxy is a software load balancer to the application of tcp and http who support a need a counterweight burden.Haproxy have the ability to control traffic of each request data from clients and showing statistics from on use each web server that it can controlling. Design and implementation of haproxy as balancer reverse a proxy be able to address the problems caused by burden excessive traffic because haproxy divide the expense request that goes into server haproxy so that the use of haproxy as load balancer can overcome the problems because the distribution of the burden known to second server backend.
