Mobile extensions to RSVP

Daniel O. Awduche, Emmanuel Agu

Abstract: RSVP (resource reservation protocol) is a receiver oriented resource reservation setup protocol targeted for integrated services packet networks (ISPNs). RSVP has a number of desirable attributes which make it a leading candidate for Internet standardization. These attributes include flexibility, robustness, and scalability. However, RSVP does not adequately address the issue of resource reservation for mobile hosts. This paper highlights the limitations of RSVP in mobile environments and proposes extensions to obviate these deficiencies. The basic characteristics of the proposed augmentations include: (1) quiescent resource reservations, (2) virtual receivers, (3) intelligent pre-allocation of resources based on analysis of user mobility patterns, and (4) predictive look-ahead dynamic dormant multicast trees.
