Pendekatan multicast berlapis membolehkan multicast IP menyesuaikan diri dengan rangkaian heterogen. Dalam multicast berlapis, setiap lapisan sesi dihantar ke kumpulan multicast yang berasingan. Lapisan ini akan dihantar pada laluan yang sama, atau pada laluan yang berbeza. Walau bagaimanapun, skim kawalan kesesakan tradisional multicast berlapis tidak mengambil kira kes apabila lapisan sesi dihantar pada laluan yang berbeza. Dalam kertas kerja ini, pada mulanya kami menunjukkan bahawa dalam protokol penghalaan mod jarang seperti PIM-SM dan CBT, lapisan sesi boleh dipetakan kepada Titik atau teras Rendezvous yang berbeza disebabkan oleh mekanisme bootstrap. Ini bermakna lapisan sesi boleh dihantar pada laluan yang berbeza. Kami kemudian menunjukkan bahawa skim kawalan kesesakan tradisional multicast berlapis tidak berfungsi dengan betul di kawasan penghalaan mod jarang. Akhirnya kami memperkenalkan Rendezvous Point berasaskan Layered Multicast (RPLM), skim kawalan kesesakan baru yang sesuai untuk kawasan penghalaan mod jarang, dan menunjukkan bahawa RPLM berfungsi dengan cekap di kawasan menggunakan protokol penghalaan mod jarang. RPLM menggunakan kadar kehilangan paket per-RP dan bukannya kadar keseluruhan untuk mengesan kesesakan pada setiap laluan, dan boleh bertindak balas terhadap kesesakan dengan cepat dengan menjatuhkan lapisan tertinggi pada laluan yang sesak. Di samping itu, RPLM secara serentak menjatuhkan semua lapisan yang tidak berguna dalam peningkatan kualiti untuk mengelakkan pembaziran lebar jalur.

Abstract: Layered multicast approach enables IP multicast to adapt to heterogeneous networks. In layered multicast, each layer of a session is sent to separate multicast groups. These layers will be transmitted on the same route, or on different routes. However, traditional congestion control schemes of layered multicast do not consider the case when layers of a session are transmitted on different routes. In this paper, at first we show that in sparse-mode routing protocols like PIM-SM and CBT, layers of a session can be mapped to different Rendezvous Points or cores due to the bootstrap mechanism. It means that layers of a session can be transmitted on different routes. We then show that traditional congestion control schemes of layered multicast do not work properly in sparse-mode routing regions. At last we introduce Rendezvous Point based Layered Multicast (RPLM), a novel congestion control scheme suitable for sparse-mode routing regions, and show that RPLM works efficiently in regions using sparse mode routing protocols. RPLM uses per-RP packet loss rate instead of the overall one to detect congestion on each route, and can react to congestion quickly by dropping the highest layer on the congested route. In addition, RPLM simultaneously drops all the layers those are useless in quality's improvement to prevent bandwidth waste.
