The Internet Protocol Journal - Volume 5, Number 2

From the Editor

The networking industry is full of acronyms, as the table of contents for this issue clearly illustrates. According to the dictionary, an acronym is "...a word formed from the initial letter or letters of each of the successive parts or major parts of a compound term." While neither BEEP nor ENUM are strictly speaking acronyms, these "short names" are becoming ever more prevalent and difficult to keep track of. We promise to continue to provide acronym expansion whenever possible.

BEEP is an example of a technology that came to life in a very short time. While IETF standards often take years from initial idea to protocol specification, BEEP seems to have happened in just over a year. There is already a textbook on BEEP from which our first article is adapted. Marshall Rose gives an overview of the BEEP framework and explains how you can get involved in its further development.

ENUM refers to the use of the Domain Name System (DNS) to look up telephone numbers and subsequently route telephone calls to the right destination using the Internet as the underlying routing fabric. This integration of the traditional telephone network with the Internet is becoming a reality and several standardization bodies are working on technologies to make this as seamless as possible. Geoff Huston explains the mechanisms and politics behind ENUM.

Our series "One Byte at a Time" examines the "Dynamic Host Configuration Protocol" (DHCP). This protocol is widely used to provide IP address and other basic routing information to clients. This is particularly useful for mobile devices, but it can be used in any network environment. Since the IP addresses are assigned as leases with a configurable time limit, DHCP also provides for effective address management. Douglas Comer explains the details of DHCP and its predecessor BOOTP.
