A fundamental characteristic of SCION is that it gives path control to SCION-capable endpoints that can choose between multiple path options, thereby enabling the optimization of network paths. The Control Plane is responsible for discovering these paths and making them available to the endpoints. The SCION Control Plane creates and securely disseminates path segments between SCION Autonomous Systems (AS) which can then be combined into forwarding paths to transmit packets in the data plane. This document describes mechanisms of path exploration through beaconing and path registration. In addition, it describes how Endpoints construct end-to-end paths from a set of possible path segments through a path lookup process. This document contains new approaches to secure path aware networking. It is not an Internet Standard, has not received any formal review of the IETF, nor was the work developed through the rough consensus process. The approaches offered in this work are offered to the community for its consideration in the further evolution of the Internet.}, }
