Hello, This draft describes the session identifier in GUE. This is a generic options that includes some different types of sessions and related state machines.
The bidirectional types (section 4.3) are intended to provide similar functionality that is in the Spud prototype protocol. We elaborated on the Spud model by adding a 3WHS for session creation and also requiring both sides to contribute values to the identifier-- this is to defend against the equivalent of SYN attacks on sessions (ie. open attacks).

Name: draft-herbert-gue-session-id Revision: 00 Title: Session Identifier Option for Generic UDP Encapsulation Document date: 2015-05-22 Group: Individual Submission Pages: 25 URL: https://www.ietf.org/internet-drafts/draft-herbert-gue-session-id-00.txt Status: https://datatracker.ietf.org/doc/draft-herbert-gue-session-id/ Htmlized: https://tools.ietf.org/html/draft-herbert-gue-session-id-00 Abstract: This specification defines the session identifier option for Generic UDP Encapsulation (GUE). This option allows an encapsulator to identify a logical session to which an encapsulated packet belongs. The session for a packet may refer to the flow or connection of an encapsulated transport protocol, and the session identifier option provides visibility into this at the encapsulation layer. Nodes may use the session identifier option to create and maintain session state for encapsulated flows, and in turn can affect packet processing on the basis of this state. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
