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

Nowadays, the existence of VoIP communication is growing fast. However, communication that is common at this time has not fulfilled the needs of specific users. For particular users, the safety and fluency of the communication is the fundamental needs. This is about VoIP communication that combined between FreeSWITCH as SIP Server, ZRTP as an encryption method to securing communication, and the use of G.729A as an audio codec. To collect the data, it will use the wireshark application for observing Quality of Service during the communication such as delay, jitter, and packet loss. While cain& able application is used for sniffing the process of communication on the network. Using a process of testing using sniffing method, communication on the network which is not using encryption can be caught and read by both wireshark and cain& able application, while communication on the network which is using encryption can not be read by both application. The result of VoIP communication using ZRTP protocol as an encryption method is can not be read and decoded by wireshark and cain& able and the use of codec G.729A is more suiteable for VoIP communication.
