“…The idea of IM is similar to other previously proposed protocols such as Scattercast, YOID, AMT, Universal Multicast (UM) and Subnet Multicast (SM) [6], [7], [8], [9], [10]. While many of these protocols require some special nodes (such as proxies or routers) or manual configuration of inter-host connections, IM is fully autonomous and does not need that.…”

Abstract-With the availability and penetration of multicastcapable routers, many local networks in today's Internet are multicast-capable. However, achieving global IP multicast is still hindered by many management and technical difficulties. This is because routers interconnecting these local multicast-capable networks, or so-called "islands," are often either multicastincapable or multicast-disabled. Traditional application-level multicast (ALM) only makes use of unicast connections to form delivery trees and has not fully taken advantage of the local multicast capability of an island. As a result, these protocols are not very efficient.In order to achieve efficient global multicast, we propose and study Island Multicast (IM) where unicast connections are used between islands while IP multicast is used within islands. We present the detailed mechanisms of the IM centralized approach. IM is simple to implement and is based on minimum spanning tree, and hence is applicable to many-to-many communication.We have implemented the protocol and done real measurements on PlanetLab. We show that our protocol significantly improves network performance (in terms of stress, delay and nodal degrees) as compared to using ALM alone.

“…Subset Multicast (SM) tries to solve the issue of connecting multicast islands by having the source island forward a copy of the data to each island [6]. While SM works independently from the underlying native multicast protocol, a source must have a database of every interested island and manage the database.…”

Abstract. We propose a new delivery scheme for 1-to-N multicast applications such as webcasting service used for the web-based broadcasting of contents streams in Internet. The proposed scheme is based on the unicast transport from a remote sender to a subnet host and the subsequent multicast transmissions to the other receiving hosts within the subnet. The main design goal of this scheme is to improve transmission efficiency over the existing unicast transports, without help of multicast-capable networks. The proposed scheme has been tested and compared with the unicast-only transports in terms of the amount of traffic generated in the subnetworks. From experimental results, we see that the proposed scheme provides a nearly same performance as IP multicasting does in the subnetwork environments. Recognizing that IP multicast seems to be a little more delayed, it is expected that the proposed scheme can be used as an alternative short-term solution for one-to-many multicast services over the unicast networks.
