This protocol is only implemented for the interaction between SIHOT.WEB and SIHOT.PMS. In certain time intervals, SIHOT.WEB sends the following message to SIHOT.PMS and backwards:
SIHOT.PMS ↔ SIHOT.WEB
<?xml version="1.0" encoding="ISO-8859-1"?> <SIHOT-DOCUMENT> <OC>KEEP-ALIVE</OC> <ID>1</ID> <TN>1</TN> <RC>0</RC> <TIME>2004-02-14T23:23:56</TIME> <MSG>OK</MSG> </SIHOT-DOCUMENT>
<TIME> contains the current time of the computer. SIHOT.PMS and/or SIHOT.WEB answer with the same message, containing the element
<TIME> with the current time of the sending computer.
If SIHOT.PMS does not answer a few times to the request, a message is/should generated and automatically send per email to the hotel administrator.
