Exploiting the advantages of connectionless and connection-oriented networks

By Malathi Veeraraghavan and Mark Karol

Abstract

This paper proposes a scheme for taking advantage of the properties of both connectionless (CL) and connection-oriented (CO) networks to carry traffic from existing applications. Specifically, it pro-poses a solution for allowing data generated by endpoints on a CL (IP) network to be redirected to CO networks if there is an advantage from the user or service provider perspective. The advantage to a user is that the user can ask for and receive a guaranteed quality of service for a specific flow. The advantage to a service provider is that bandwidth utilization in a packet-switched CO network is bet-ter than in a CL network with precomputed routes since bandwidth can be dynamically allocated to flows on an as-needed basis. These advantages only exist when the CO network is operated in a switched mode (i.e., some connection “setup ” actions are performed for each arriving flow) rather than in a provisioned mode (where all these actions are performed a priori). This paper addresses the problem of how to internetwork a CL (IP) network with a switched CO network. Our solution is based on interworking routing schemes of the two networks, “halting ” or “turning around ” datagrams during connection setup, and performing protocol conversion rather than encapsulation (on the user plane) to reduce overheads, which results in a further improvement o
