Yodel: A Layer 3.5 Name-Based Multicast Network Architecture For The Future Internet
Multicasting refers to the ability of transmitting data to multiple
recipients without data sources needing to provide more than one copy of the
data to the network. The network takes responsibility to route and deliver a
copy of each data to every intended recipient. Multicasting has the potential
to improve the network efficiency and performance (e.g., throughput and
latency) through transferring fewer bits in communicating the same data to
multiple recipients compared with unicast transmissions, reduce the amount of
networking resources needed for communication, lower the network energy
footprint, and alleviate the occurrence of congestion in the network. Over the
past few decades, providing multicast services has been a real challenge for
ISPs, especially to support home users and multi-domain network applications,
leading to the emergence of complex application-level solutions. These
solutions like Content Delivery and Peer-to-Peer networks take advantage of
complex caching, routing, transport, and topology management systems which put
heavy strains on the underlying Internet infrastructures to offer multicasting
services. In reality, the main motivation behind the design of these systems is
rather sharing content than offering efficient multicast services. In this
paper, we propound Yodel, a name-based multicast network architecture that can
provide multi-domain multicast services for current and future Internet
applications. Compared to the wider array of other name-based network
architectures with clean-slate infrastructure requirements, Yodel is designed
to provide multicast services over the current Internet infrastructure. Hence,
Yodel puts forward several design goals that distinguish it from other
name-based network architectures with inherent multicast capabilities. This
paper is prepared to discuss the Yodel architecture, its design goals, and
architectural functions.Comment: Contains animated figure
