An Efficient RSVP/Mobile IP Interworking Scheme

Abstract

During the past years, several attempts have been made to develop functionality for mobility management support and QoS provision in the realm of the IP networks. Since IP was not designed to support such functionality, new protocols have been speci ed and implemented to tackle these issues. Mobile IP is currently the dominant protocol that allows users to retain connectivity while roaming in IP networks. RSVP (Resource reSerVation Protocol) is a well established protocol for reserving network resources to support QoS requirements. These protocols, when deployed separately, can work quite eciently. However, if their functionality is combined, several ineciencies arise in terms of QoS deterioration and misuse of the network resources
