PCEP operates over TCP using a registered TCP port (4189). This allows the requirements of reliable messaging and flow control to be met without further protocol work. All PCEP messages MUST be sent using the registered TCP port for the source and destination TCP port.
It should say:
PCEP operates over TCP using a registered TCP port (4189). This allows the requirements of reliable messaging and flow control to be met without further protocol work. A PCE MUST listen for incoming connections at the registered port and a PCC SHOULD use the registered port as source port but MAY use any source port (e.g. ephemeral port).
