Abstract — This paper shows how the multicast nature of proposed future publish/subscribe network architectures can assist mobility. Publish/subscribe is an information-centric networking paradigm. Unlike the current send/receive based Internet architecture which favours the sender of information, the publish/subscribe paradigm leads to a more balanced relationship between entities. Publish/subscribe is considered a promising architecture for the future Internet as it can potentially address various current Internet problems, such as spam and (Distributed) Denial of Service attacks. In a pub/sub architecture all data are transmitted via multicast and end host identification, which has a less critical role to begin with, is decoupled from location identification. In such an environment, fast mobility can be supported effectively, particularly for continuous media distribution (such as mobile TV) and other types of real-time multimedia applications. In this paper, a prototype overlay multicast scheme based on Scribe is extended to support mobility. We compare this scheme against an alternative solution based on Mobile IPv6 and demonstrate the effectiveness of the proposed approach and the basic trade-offs.
