5.6.3. Actions

Actions in the automaton are caused by events and typically indicate the transmission of packets and/or an action to be taken on the connection. In this section, we will ignore the I- and R- prefixes, since the actual action would be identical, but it would occur on one of two possible connections.

Snd-Conn-Req

A transport connection is initiated with the peer.

Accept

The incoming connection associated with the R-Conn-CER is accepted as the responder connection.

Reject

The incoming connection associated with the R-Conn-CER is disconnected.

Process-CER

The CER associated with the R-Conn-CER is processed.

Snd-CER

A CER message is sent to the peer.

Snd-CEA

A CEA message is sent to the peer.

Cleanup

If necessary, the connection is shut down, and any local resources are freed.

Error

The transport layer connection is disconnected, either politely or abortively, in response to an error condition. Local resources are freed.

A received CEA is processed.

A DPR message is sent to the peer.

A DPA message is sent to the peer.

Disc

The transport layer connection is disconnected, and local resources are freed.

An election occurs (see Section 5.6.4 for more information).
