This chapter discusses SCION isolation domains in more detail. As briefly sketched in Chapter 2, an isolation domain (abbreviated as ISD to distinguish it from the common abbreviation ID) constitutes a logical clustering of the Internet’s most coarse-grained organizational unit, namely that of an autonomous system, or AS for short. An AS is a self-contained network administrated by a single entity (e.g., by an Internet service provider (ISP) or a university) and communicates with other ASes through well-defined interfaces based on contractual business relations. Figure 2.1 on Page 18 sketches how ASes are grouped into ISDs.
