L1: Introductory. These sessions are intended for the most basic, beginner-level audience. No prerequisites are assumed, and no prior knowledge of the subject matter is expected of the audience for a full understanding of the session content.
L2: Intermediate. These sessions are intended for a technical audience who have some knowledge of the subject matter but who need additional information on the technology, architecture, protocol, design, deployment or troubleshooting details. There is an assumption of prerequisites or recommended sessions for Intermediate level sessions (which are defined in the session detail and listed in the session abstract).
L3: Advanced. These sessions are intended for a very technical audience. The session content is focused on fine detail, therefore a thorough understanding of the intermediate level technical detail on a particular subject is assumed and expected for the audience to gain any benefit from an advanced level session. There is an assumption of prerequisites or recommended sessions for Advanced level sessions (which are defined in the session detail and listed in the session abstract).
