ABSTRAKSI: Dewasa ini, jaringan komunikasi data terus mengalami perkembangan
yang pesat. Tidak hanya dari sisi perangkat, tetapi juga dari sisi aplikasi dan
sistem transmisi yang digunakan. STT Telkom sebagai salah satu kampus berbasis
teknologi telekomunikasi berusaha memanfaatkan perangkat dan jaringan yang
tersedia untuk meningkatkan kualitas pendidikannya dan memberikan kemudahan
mahasiswa dalam mengakses informasi dan materi kuliah yang diajarkan.
Salah satu bentuk realisasi dari program tersebut adalah dibangunnya LAN
(Local Area Network) dan WLAN (Wireless Local Area Network) yang telah
mencakup semua bangunan di STT Telkom termasuk kawasan kost mahasiswa
disekitar kampus. Tidak hanya itu, bandwidth yang disediakan juga sudah
termasuk dalam kategori broadband. Tetapi pada kenyataannya, jaringan tersebut
belum dimanfaatkan secara optimal. Untuk itu, dalam Tugas Akhir ini akan
dicoba diimplementasikan sebuah aplikasi video conference menggunakan
protokol H.323 berbasis web. Dengan adanya aplikasi ini diharapkan dapat
membantu proses belajar mengajar on-line, rapat on-line, dan kegiatan lain yang
membutuhkan tatap muka secara on-line. Sebelum aplikasi ini diimplementasikan,
perlu dilakukan pengkajian dan analisa terhadap performansi jaringan (delay,
jitter, packet loss, dan throughput) sebagai bahan pertimbangan kelayakan
implementasi.
Setelah dilakukan sejumlah percobaan dengan beberapa skenario
didapatkan hasil bahwa delay arah downlink lebih baik dan teratur daripada uplink
dengan delay rata-rata <250ms, jitter uplink rata-rata <30 ms sedangkan downlink
rata-rata >30 ms, packet loss arah uplink rata-rata 0% dan arah downlink
bervariasi dengan rata-rata <10%, throughput cukup baik, kualitas video cukup
baik berdasarkan MPQM yaitu rata-rata bernilai 3, dan secara keseluruhan lokasi
dengan kualitas terburuk didapat di gedung H (GSG)Kata Kunci : LAN, WLAN, video conference, protokol H.323, web, delay, jitter, packet loss, throughput.ABSTRACT: Nowadays, data communication network keeps on growing rapidly. Not only be
seen from the device side but also from the application and transmission system
used. STT Telkom as one of telecommunication technology based campuses
attempts to take benefits from available devices and network to improve its
education quality and to make easier for the students in accessing informations as
well as given lecture materials.
One of the program realizations is the LAN and WLAN development which
has covered entire building in STT Telkom includes boarding house area around
the campus. The given bandwidth has also already been in broadband category.
But in reality, the network has not been used optimally. Thus, in this final project
there will be an implementation of video conference application using H 323
protocol based on web. The existence of this application is expected to be able to
support online lecture, online meeting, and other online activities. Before being
implemented, this application needs network performance analysis and
examination (delay, jitter, packet loss, and throughput) as a consideration for
implementation feasibility.
A number of experiments using several scenarios are revealing result that
the downlink direction delay is more regular and better than the uplink, the
average delay is less than 250ms, the average jitter uplink is less than 30ms
whereas the average downlink more than 30ms, the average uplink direction
packet loss is 0% and the downlink direction varies with less than 10% on the
average, the throughput is good enough, the video quality is good enough based
on MPQM which is 3 on the average, and on the whole, it can be concluded that
the location with the worst quality is H building (GSG).Keyword: LAN, WLAN, video conference, protokol H.323, web, delay, jitter, packet loss, throughput.
