Ketika mereka meninggalkan Tier 1 backbone ISP, mereka bergerak melalui lain Tier 2 ISP dalam perjalanan ke server tujuan di www.ripe.net.
a. Buka file output pertama traceroute dan menjawab pertanyaan-pertanyaan berikut.1) Apa adalah alamat IP dari router lokal POP Anda? (64.180.160.254)________________________________________________________________________2) Berapa banyak hop traceroute melakukan paket diambil selama perjalanan dari komputer host ke tujuan? ____(13 hop)________________________________________________________________
3) Berapa banyak yang ISP yang berbeda paket traceroute melewati perjalanan dari komputer host ke tujuan? _________(3 perbedaan)_____________________________________________________
4) Daftar alamat IP dan URL dari semua perangkat di output traceroute dalam urutan seperti yang terlihat pada lembar kerja Rute dilacak.
5) Pada kolom Pemilik Jaringan worksheet, mengidentifikasi ISP memiliki setiap router. Jika router milik LAN Anda, menulis “LAN”. Dua yang terakhir bagian dari URL menunjukkan nama ISP. Sebagai contoh, sebuah router yang memiliki “sprint.net” dalam URL-nya milik jaringan ISP yang disebut Sprint.
6) Apakah lulus traceroute melalui router yang tidak teridentifikasi antara dua ISP? Ini mungkin merupakan IXP. Jalankan perintah whois utilitas atau fungsi whois program traceroute visual untuk mengidentifikasi kepemilikan router itu. Atau, buka http://www.arin.net/whois untuk menentukan kepada siapa IP yang ditetapkan.b. Lengkapi lembar kerja menggunakan file output traceroute untuk setiap URL tujuan lain.c. Bandingkan hasil anda dari file output yang berbeda traceroute. Apakah Anda ISP terhubung ke ISP yang berbeda untuk mencapai tujuan yang berbeda? ______________________________________(tidak)____________________________________
d. Jika anda telah menjalankan traceroute dari jaringan komputer yang berbeda, periksa output untuk file traceroute juga. Apakah jumlah hop yang berbeda untuk mencapai tujuan yang sama dari ISP lokal yang berbeda? ISP yang mampu mencapai tujuan dalam sedikit hop? ___________________________________(tidak), ISP tujuan (destination of ISP network)______________
Langkah 3: Peta konektivitas dari ISPa. Untuk setiap output traceroute, menggambar diagram pada selembar kertas terpisah menunjukkan bagaimana Anda ISP lokal interkoneksi dengan ISP lain untuk mencapai URL tujuan, sebagai berikut:1) Tampilkan semua perangkat secara berurutan dari router LAN ke server situs tujuan. Label semua perangkat dengan alamat IP mereka.2) Gambarkan kotak sekitar router POP lokal yang Anda identifikasi, dan label kotak “POP”.3) Gambar sebuah awan ISP di semua router yang memiliki satu sama ISP, dan label awan dengan nama ISP.4) Gambarkan kotak sekitar setiap router IXP yang Anda identifikasi, dan label kotak “IXP”.b.
