CoreCast: How core/edge separation can help improving inter-domain live streaming

The rapid growth of broadband access has popularized multimedia services, which nowadays contribute to a large part of Internet traffic. Among this content, the broadcasting of live events requires streaming from a single source to a large set of users. For such content, network layer multicast is the most efficient solution, but it has not found wide-spread adoption due to its high deployment cost. As a result, several application layer solutions have been proposed based on large-scale P2P systems. These solutions however, are unable to provide a satisfactory quality of experience to all users, mainly because of the variability of the peers and their limited upload capacity. In this paper we advocate for a network layer solution that circumvents the prohibitive deployment costs of previous approaches, taking advantage of the rare window of opportunity offered by the Locator/Identifier Separation Protocol (LISP). This new architecture, motivated by the alarming growth rate of the defa...
