RSVP for LEO satellites

The Internet Engineering Task Force (IETF) is working on extending the traditional TCP/IP model for supporting multimedia and real-time applications on the Internet. Thus, new protocols have been developed such as the resource reservation protocol (RSVP). At the same time, there has been a growing interest in using low Earth orbit (LEO) satellites. In the near future, when the Internet with multimedia and real-time support is widely deployed, it will need to work over LEO satellite networks. This paper surveys the networking issues related to RSVP over LEO satellite networks. It also describes different approaches for extending RSVP for supporting satellite users.
