ABSTRAKSI: Bidirectional Protocol Independent Multicast (BIDIR-PIM) adalah salah satu protokol ruting IP-multicast. BIDIR-PIM membangun bidirectional shared trees yang dapat menghubungkan sumber multicast dengan penerima trafik multicast. Pada proses distribusi trafik dari sumber multicast, PIM-SM menggunakan proses enkapsulasi atau proses pengiriman PIM Registering Packets yang membutuhkan proses, bandwidth, dan delay overheads yang signifikan. PIM-SM juga menggunakan source-specific state yang membutuhkan protokol dan memori tambahan. BIDIR-PIM terlepas dari proses enkapsulasi dan source-spesific state yang terdapat pada PIM-SM.
Pada Tugas Akhir ini, BIDIR-PIM disimulasikan ke dalam jaringan TCP/IP intradomain multicast kemudian dianalisa performansi dalam menangani trafik real-time dan dibandingkan dengan PIM-SM. Diharapkan BIDIR-PIM dapat memberikan performansi lebih baik dari PIM-SM.
Hasil dari tugas akhir ini yaitu, untuk variasi bandwidth link jaringan; BIDIR-PIM memberikan nilai delay rata-rata 28,2329 ms, packet loss nol persen, throughput rata-rata 0,1316 Mbps. PIM-SM memberikan nilai delay rata-rata 28,1079 ms, packet loss nol persen dan rata-rata throughput 0,1311 Mbps. Untuk variasi jumlah penerima multicast; BIDIR-PIM memberikan nilai delay maksimum 28,1742 ms, packet loss nol persen, throughput rata-rata 0,1273 Mbps. PIM-SM memberikan nilai delay maksimum 28,1096 ms, packet loss nol persen, throughput rata-rata 0,1272 Mbps. Untuk perubahan rate video menjadi 384 Kbps; BIDIR-PIM memberikan nilai delay 9,054 ms, packet loss nol persen, throughput 0,3968 Mbps. PIM-SM memberikan nilai delay 9,035 ms, packet loss nol persen, throughput 0,3965 Mbps. Untuk penambahan background TCP sebesar 90% dari bandwidth link jaringan dengan rate video 384Kbps; BIDIR-PIM memberikan nilai delay 9,612 ms, packet loss 0,83%, throughput 0,3805 Mbps. PIM-SM memberikan nilai delay 9,526 ms, packet loss 0 persen, throughput 0,3797 Mbps.Kata Kunci : IP-Multicast, PIM-SM, BIDIR-PIM.ABSTRACT: Bidirectional PIM (BIDIR-PIM) is a variant of PIM Sparse-Mode (PIM-SM) that builds bidirectional shared trees connecting multicast sources and receivers. In the process of distribution of multicast traffic from sources, PIM-SM contained encapsulation process or the process of sending PIM Registering Packets that require significant process, bandwidth, and delay overheads and PIM-SM uses source-specific state which requires additional protocol and memory. While BIDIR-PIM regardless of the encapsulation process and from source-specific state.
BIDIR-PIM will be simulated into the TCP / IP intradomain multicast network. Its performance will be analyzed and compared with PIM-SM in handling the real-time traffic.
The results are, for bandwidth link variation; BIDIR-PIM gives 28.2329 ms average delay, zero percent packet loss, 0.1316 Mbps average throughput. PIM-SM gives 28.1079 ms average delay, zero percent packet loss, 0.1311 Mbps average throughput. For multicast receivers number variation; BIDIR-PIM gives 28.1742 ms maximum delay, zero percent packet loss, 0.1273 Mbps average throughput. PIM-SM gives 28.1096 ms maximum delay, zero percent packet loss, 0.1272 Mbps average throughput. For video rate changes to 384 Kbps; BIDIR-PIM gives 9.054 ms average delay, zero percent packet loss, 0.3968 Mbps average throughput. PIM-SM gives 9.035 ms average delay, zero percent packet loss, 0.3965 Mbps average throughput. With the 90% TCP background traffic addition of bandwidth link and 384 Kbps video rate; BIDIR-PIM gives 9.612 ms average delay, 0.83% packet loss, 0.3805 Mbps average throughput. PIM-SM gives 9.d526 ms average delay, zero percent packet loss, 0.3797 Mbps average throughput.Keyword: IP-Multicast, PIM-SM, BIDIR-PIM.
