-
- Guidelines for Internet Measurement Activities
-
-
- Status of this Memo
-
- This memo provides information for the Internet community. It does
- not specify an Internet standard. Distribution of this memo is
- unlimited.
-
- Summary
-
- Measurement of the Internet is critical for future development,
- evolution and deployment planning. Internet-wide activities have the
- potential to interfere with normal operation and must be planned with
- care and made widely known beforehand. This document offers guidance
- to researchers planning Internet measurements.
-
- This RFC represents IAB guidance for researchers considering
- measurement experiments on the Internet. This RFC does not represent
- a standard for the Internet but the Internet Activities Board
- strongly urges that Internet users follow the guidelines out of
- courtesy and professional consideration for the Internet community.
-
- Guidelines
-
- The Internet has undergone dramatic growth in connectivity, use, and
- quality of service over the past several years. As this growth
- continues and the Internet is used for increasingly diverse and
- demanding purposes, it is vital to collect data about a range of
- functions, from low-level packet switching services to considerations
- for the networking expectations of individual applications. Such
- data is vital to research and engineering planning activities, as
- well as to ensure the continued development of the operational
- infrastructure. Yet, it is also important that data collection
- activities do not interfere with the operational viability and
- stability of the network, and do not violate considerations regarding
- privacy, security, and acceptable use policies of the network. In
- this light, the Internet Activities Board offers the following basic
- guidelines for network measurement activities.
-
- In general, any data collection activity should be undertaken with
- professional consideration of its impact on the services and users of
- the network, and activities should be planned to achieve operational
-

-
- or research goals with minimal impact. In some cases, data may be
- collected continuously, for example to measure packet counts or the
- distribution of use of specific applications. In other cases, the
- planned investigations will be too demanding to be undertaken
- continuously, because of the intensity of effort required by the
- researcher or the traffic load on the underlying network
- infrastructure. Any data collection activity should be designed with
- careful consideration of this type of issue, and should be tested
- thoroughly before being deployed on the Internet. Any individual
- initiating a network measurement activity should alert the relevant
- service providers using mechanisms such as bulletin boards, mailing
- lists and individual mail communications.
-
- Furthermore, the data being collected must not be gathered using
- break-ins to network systems or other illegal or unethical
- techniques. If a measurement activity might be construed as a
- possible security intrusion, the researcher should make it easy for a
- system administrator at a remote site to determine that the activity
- is not a break in attempt, by informing the CERT, making information
- about the study easily available by anonymous FTP or other means
- [1,2,3].
-
- More specifically, an individual attempting a network measurement
- activity should ensure that the following conditions are met:
-
- 1) the data collected will not violate privacy, security, or
- acceptable use concerns,
-
- 2) if the aggregated data has a potential for privacy intrusions,
- the researcher must protect privacy, for example by limiting
- published statistics in such a fashion that individual users or
- institutions are not identified,
-
- 3) if the data collection activity may be construed to be a
- security violation, the researchers are strongly advised to
- inform the CERT in advance, and, if applicable, request some
- guidance,
-
- 4) the data collection does not unduly load or otherwise interfere
- with the network or attached machines, in particular, if at all
- feasible, non-invasive measurement, like passive monitoring,
- should be considered as the first choice,
-
- 5) if there is an operational impact, the service providers must be
- contacted,
-
- 6) the study goals, methodology, and plans are widely available, in
- a fashion that requires minimal effort to locate and retrieve,
-

-
-
- and
-
- 7) if the activity would impose undue burden on a remote machine or
- network, the measurements should not be performed without prior
- explicit permission.

- Security Considerations
-
- The body of this memo does discuss security issues related to network
- measurement, particularly the potential confusion of benign
- measurement with hostile security attacks.
