Dear all,
While working on the implementation guidelines draft, Paul Aitken discovered the following problem: the protocol draft doesn't specify what to do for template withdrawal message when TCP is the transport protocol.
What's currently in the draft:
- section 10.2.4.4 "template management" in case of SCTP
- section 10.3.6 "template management" in case of UDP
Proposed text to be added in section 10.4.2.2 "template management" for TCP:
"The Templates that are not used anymore SHOULD be deleted. Before reusing a Template ID, the Template MUST be deleted. In order to delete an allocated Template, the Template is withdrawn through the use of a Template Withdrawal Message over the TCP connection."
Any objections on this clarifying sentence?
Regards, Paul and Benoit.

What's currently in the draft:
- section 10.2.4.4 "template management" in case of SCTP
"When the transport protocol is SCTP the default Template Management described in Section 8 is used."This points to "The Template Withdraw Message MUST be sent on the SCTP stream zero with full reliability." in section 8
- section 10.3.6 "template management" in case of UDP
"Template Withdrawal Messages SHOULD NOT be sent over UDP."- but there is not mention of the "template withdrawal message in the section 10.4.2.2 "template management" for TCP
