A delay based routing protocol with support for common services

Abstract

In this paper we propose a new routing protocol called Delay Based Routing Protocol (DBRP). DBRP is a flexible distance vector routing protocol with a metric based on delay. It natively supports IPv4 and IPv6, and can also carry information for common services such as the IP addresses of the DNS servers. This last feature makes it unique, since existing routing protocols only transport routing information. DBRP also has support for authentication and encryption. It operates over the data link layer and is based on Type-Length-Value (TLV) tuples; therefore, DBRP can be easily extended to other existing or future network protocols. Additionally, by defined new TLV tuples, other common services (e.g., NTP, NIS, NIS+, SIP, log, and printer servers), as well as other hash and encryption algorithms can be simply added to our protocol.
