The following sections present the interactions (in the form of UML Sequence Diagrams) between transmit and receive endpoints while closing a channel. Various error conditions are presented in order to show nominal, delayed, and worst case scenarios.
The hexagonal icons represent the TEP states while the dashed green lines represent data flows (packets) between the endpoints across a link. In the case where errors are present and a packet is either corrupted or lost the UML lost message icon is used to denote this error condition instead of the dashed green line.
