Abstract

While the Internet keeps its penetration into every facet of life and every corner of the globe, two things stand out. One is the hunger for high quality of services to convey audio and video data. The other is the desire for ubiquitous connections. Combining the two we have an Internet that is capable of supporting multimedia communications for nomadic users on the move. To have a high quality connection, resource must be allocated along the connection path. The current Internet standard for resource reservation is RSVP (Resource reSerVation Protocol), which is receiver-initiated and allows one-to-one or one-to-many communication to have resource reserved in the path from sender to receiver(s). To support mobile users, the Internet also has the mobile IP standard. Mobile IP allows a mobile host to roam from one subnet to another seamlessly. However, several problems need to be solved before we can support QoS communications for mobile users by applying RSVP to mobile IP. In this paper, we identify four problems related to RSVP over mobile IP. The problems are the resource pre-reservation problem, the RSVP tunneling problem, the common path identification problem, and the mobile proxy problem. We also survey the various solutions proposed by many papers.
