Island Multicast: Combining IP Multicast With Overlay Data Distribution

Abstract: Abstract-Traditional overlay protocols use unicast connections to form delivery trees. While it can achieve global multicast across the Internet, it is not as efficient as IP multicast. In this paper, we integrate IP multicast into overlay data distribution to improve delivery efficiency. We investigate island multicast where unicast connections are used to connect multicast domains and IP multicast is used within multicast domains. We first explore a centralized island multicast protocol (termed CIM), which r… Show more

“…Based on multicast proxy function, the delegation of overlay nodes in multicast domains can construct a flexible and reliable transport tree as backbone for inter-domain connectivity. Recently, the universal multicast [5], and island multicast [6] are proposed to perform overlay multicast. Besides the backbone overlay connectivity, the proxies need to deliver data packets to end hosts via IP multicast or ALM in local network.…”

“…For such scenarios, where one-to-many content delivery to large number of receivers is required, IP multicast [44,68] is perhaps the most efficient solution in terms of bandwidth consumption. However, although often supported within the confinements of campus, enterprise or service provider networks, IP multicast deployments have been generally done disregarding inter-domain connectivity, thereby resulting in disconnected multicast islands [82,139,144]. One fundamental cause for the slowly advancing deployment is the requirement that all routers be upgraded to support the protocol.…”

“…Island Multicast (IM) [82] is a P2P architecture that optimizes content delivery efficiency by exploiting intra-domain multicast deployments. Similarly to Lcast, it uses unicast to connect multicast islands however unlike Lcast, the overlay is constructed with end-hosts.…”
