A DNS-aided Application Layer Multicast Protocol

A variety of issues, both technical and commercial, has hampered the widespread deployment of IP multicast in the global Internet. Application Level Multicast (ALM) approaches using the overlay network have been recently proposed as a viable alternative to IP multicast. In this paper, we proposed a DNS-aided ALM which builts overlay network with the help of the existing Domain Name Service (DNS). The simulation study shows that the proposed protocol have better Relative Delay Penalty and Link Stress for performance, but with lower protocol overhead and Resource Usage for multicast transmission in comparison with two existing ALM solutions, NARADA and NICE.
