Pengembangan Sistem IOSS (IPB Open Screen Sharing) Menggunakan Bahasa Pemrograman Java

Abstract

Screen sharing application on LAN equipped room has a potential to replace projector duty. NetOp School is one of many softwares which has screen sharing feature. However, NetOp School is a shareware software and not open source. IOSS (IPB Open Screen Sharing) is an open source screen sharing software built from Java object oriented programming language. This screen sharing software implemens multithreading in which one thread used to serve one client connection and one thread implemens one class which is needed to run real time and independently from another classes activity. The socket programming implementation in IOSS is using TCP protocol and client-server architecture. IOSS uses JPEG as standard image format used for screen sharing. IOSS test result showed that size of connected client does not always gain slow response time. It was shown from the fastest and slowest response time, respectively, 36 ms and 3625 ms which is occurred in client size of 10 and system frame rate setting used was 30 fps. The performance shown by IOSS is still far from what is expected. This can be shown by highest and lowest frame rate received by one client, respectively, is 29 fps and zero fps. Bandwidth used by IOSS reachs peak on 100.2 Mbps, occurred on client size of 10 and system setting used was 70 fps. Response time, frame rate received by client and bandwidth used is not correlated to system frame settings yet size of connected client.
