The Internet Engineering Curriculum Repository Web site attempts to "coordinate and make available on the web a 'distributed living curriculum' in network engineering." At present, it contains sections on Infrastructure Support, Developing Protocols, Applications, Social, Code Development, and Imminent Technologies. Each of these categories is further subdivided; these subcategories point to existing higher education classes in the topic, when available, as well as to other resources relating to the topic. The "distributed" aspect of this project means that the site will always be a work in progress; where class information is presently missing, a forms-based interface allows you to add the URL of your class. In this way, a "living curriculum" can be built over time.
