Abstract: Traditionally, IP address is hard coded in the machine's local configuration file. With the introduction of RFC951, BOOTP becomes a widely used method to assign IP address and other configuration parameters for a station. This makes the use of diskless station as clients become possible. As time goes by, the computing environments nowadays are very different from the day when RFC951 was proposed. As the networks become larger and larger, IP address management becomes a serious problem for the network administrator. In 1993, R. Droms of Bucknell University proposed the Dynamic Host Configuration Protocol (DHCP) in RFC1531 to facilitate dynamic IP address assignment. However, this protocol is very complex and requires quite a lot of changes. At the same time, it introduces some additional problems both to the network loading and reliability. This thesis proposes another new protocol - the Dynamic BOOTP (DBOOTP), which has similar objective as DHCP but using a completely different approach. The DBOOTP only makes a small change on the client side and allows BOOTP, DHCP as well as DBOOTP client to use its dynamic IP address assignment feature. The major difference between DBOOTP and BOOTP/DHCP is its distributed nature, which is made possible by nowadays advanced technology to keep it cost effective. Such distributed nature also helps to solve many problems that had not and cannot be addressed by both BOOTP and DHCP. A simulation of the DBOOTP and DHCP environment has been done to compare their performance. The experiment result shows that the DBOOTP is several times faster than the DHCP. A brief comparison with DHCP has also been conducted. Together with its simple implementation, it is a very good candidate to replace the BOOTP and DHCP for IP address assignment. Also, possible future development and recommendation on implementation have been discussed.
