ANALYTICAL STUDY OF QoS (Quality of Service) IN THE IMPLEMENTATION OF VOICE COMMUNICATION APPLICATION VoIP (Voice over Internet Protocol) ON THE INTRANET NETWORK AT THE UNIVERSITY OF LAMPUNG

Decline in the quality of a network can be caused by increasing the number of network users. The same case happened on the Unila intranet, quality of intranet degradation will cause packets delayed or even lost. To determine the performance, measurement especially in the implementation voice application. Network performance will be seen from the measurement of QoS (Quality of Service) on the Unila intranet. Network measurement is performed by active measurement with direct measurement to a pre determined scenario and considered to the three parameters: throughput, delay, and jitter by using DITG software. Using UDPprotocol as a protocol for sending voice packets and using three different audio codec at each measurement scenario there are, G.711, G.723.1, and G.729. According to the theory, jitter will increase if delay value is higher. The resulting of jitter and delay value will affect the throughput value. If the jitter and delay value increase, the throughput value will decrease. Research results are not too different from the theory.Throughput value from measurement will be smaller if the jitter and delay value increase. On the Unila LAN,performance of G.711 codec is better than other codec because this codec produces smaller delay and jitter,and the result for throughput is higher than that of other codec

Perancangan dan Analisa Kinerja Fiber to the Building (FTTB) untuk Mendukung Smart Building di Daerah Urban

The development of digital technology makes it easy for humans to do activities, including compliance with the requirement of voice, data, and video communication in office buildings. Infrastructures are a primary consideration for a reliable connection, large-capacity, and stable communication lines. Recently, Fiber-optic communication systems are now the backbone of information signal delivery technology. This paper proposes a design of optical fiber transmission media for deployment in urban office buildings. It has been called fiber to the building (FTTB), which uses a fiber optic communication system to support the availability of multimedia network in an office area. A typical office building in an urban area has a multilevel structure that is used by various companies with multimedia network access services to support business activities. This study considers XGPON technology as a fiber optic-based broadband access technology that is deemed appropriate to the needs of the use of a multimedia network. The design begins with conducting a data collection survey. The next is the chosen device components based on the estimated distribution of the number of users. There are three parameters will be calculated include Power Link Budget (PLB), Rise Time Budget (RTB), and Bit Error Rate (BER), to determine the design feasibility. Based on PLB, RTB, and BER data, the proposed fiber to the building (FTTB) can meet the parameters to be achieved in the design, namely PLB of -27,24 dBm for downstream and -11,68 dBm for upstream, the value of is 0,049 ns, and value of BER is 0,186 x 10-1085. The design of FTTB can meet the requirement of users with a bandwidth of 9014,4 Mbps for 1200 users
