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 pada gambar berikut.

Gambar Membuat Folder dan Meletakkan File .Tcl

3. Apabila sudah selesai dilakukan, maka kembali ke “command line” untuk proses pengujian simulasi pada NS-2. Pada “command line” ketik sebuah perintah “cd” yang mana fungsinya kita untuk masuk kedalam folder yang kita buat sebelumnya, kalau pada simulasi ini nama foldernya “Tanpa Pengaturan beban

protokol” yang dapat terlihat pada gambar dibawah. Kemudian tekan “Enter”.

5. Pada gambar dibawah, menunjukkan program NS-2 sedang berjalan.

7. Kemudian, dari simulasi pada NS-2 didapat sebuah file yang berbentuk .txt yang nantinya kita olah kedalam Ms.Exel untuk mendapat hasil simulasi yang kita inginkan. Untuk Tugas akhir ini hanya menganalisa permintaan client saja sehingga file dengan nama “udprec” yang diolah nantinya. Seperi yang terlihat pada gambar dibawah.

8. Pada Gambar dibawah, itu adalah salah satu isi hasil simulasi yang telah dilakukan dan hasil simulasi tersebut di olah menggunakan Ms.Exel agar didapat perhitungan delaydan packet loss.
