- Gerla, Mario
- Persons Present:
- Gerla and Fidler.
- Place Conducted:
- Gerla's office at UCLA in Los Angeles, California.
- Supporting Documents:
- Records relating to the interview are located in the office of the UCLA Library's Center for Oral History Research.
- Interviewer Background and Preparation:
- The interview was conducted by Bradley Fidler, Assistant Researcher, UCLA Computer Science Department; Ph.D. UCLA (History of Science). Fidler prepared for the interview by reading extensive primary source documents that were generated by the Network Measurement Center between 1969 and 1975, as well as materials from UCLA’s work on the ARPANET after the Network Measurement Center was closed in 1975. Many of these documents were available to him through the archive maintained by the Kleinrock Center for Internet Studies at UCLA, a part of the UCLA Special Collections. As part of his research for the Defense Advanced Research Projects Agency at the UCLA Computer Science Department, the interviewer has studied at length ARPANET technical and policy documents, and has interviewed and spoken with other key individuals from the early ARPANET. The interviewer conducted background research on each interviewee by completing a brief pre-interview, obtaining their résumé or CV, reviewing their published works, if any, reading documentary materials that shed further light on their roles in ARPANET history, and reading any existing interviews.
- Processing of Interview:
- The transcript is a verbatim transcription of the recording. It was transcribed by a professional transcribing agency using a list of proper names and specialized terminology supplied by the interviewer. Gerla was then given an opportunity to review the transcript but made no corrections or additions.

- Series Statement:
- The purpose of this oral history series is to document the context and early technological development of the ARPANET, the network that went online in 1969 and grew into the Internet. Interviewees include the Center’s Principal Investigator, three researchers, and the center administrator. The Network Measurement Center is significant in the history of the ARPANET and the Internet because it was the first systematic study of a large, general purpose computer network. In addition to testing and validating theories about computer networks, staff at the center were active in detecting and suggesting areas where the technologies could be improved. The center was also involved in experiments with radio and satellite networks that led to the development of TCP/IP, the protocol suite that drives the modern Internet. This series of interviews was made possible through funds provided by Gold Shield, Alumnae of UCLA.
