Analisis Kinerja Content Delivery Network yang Menggunakan Webmapper

LAMPIRAN 1
Proses Saat Menjalankan Simulasi NS-2
1. Hal yang pertama dilakukan adalah membuka “command line” pada OS
Ubuntu 12.35. Dengan cara “Ctrl + Alt + T, apabila sudah dilakukan akan
terlihat seperti gambar berikut:

2. Pada “Terminal” ketik perintah “cd” yang berfungsi untuk masuk kedalam
folder yang telah dibuat. Pada simulasi ini nama folder yang digunakan
“webmapper”. Kemudian tekan “Enter”.

3. Setelah selesai ketik perintah “ns” yang berfungsi untuk menjalankan program
NS-2. Lalu tekan “Enter”.

4. Pada gambar dibawah menunjukkan proses simulasi NS-2 sedang berjalan

5. Pada saat proses simulasi sudah selesai, akan muncul display out .nam yang
sudah dilakukan menggunakan program. Untuk melihat hasil simulasi klik
“Play Forward”.

6. Dari hasil simulasi pada NS-2 didapat file yang berbentuk.txt. Data tersebut
dipindahkan kedalam MS.Excel untuk menghitung Qos. Untuk tugas akhir ini
hanya menganalisa permintaan client saja sehingga file dengan nama “udprec”
yang akan digunakan.
