Med, That looks great. Thanks for accommodating my concern. Kind regards, -Peter -----Original Message----- From: mohamed.boucadair@orange.com [mailto:mohamed.boucadair@orange.com] Sent: Wednesday, April 10, 2013 12:49 AM To: Peter Yee; draft-ietf-pcp-upnp-igd-interworking.all@tools.ietf.org Cc: gen-art@ietf.org; ietf@ietf.org Subject: RE: Gen-ART review of draft-ietf-pcp-upnp-igd-interworking-07 Dear Peter, I changed the text as follows: OLD: If the requested external port is not available, the PCP server will send a CANNOT_PROVIDE_EXTERNAL error response. If a short lifetime error is returned, the IGD-PCP IWF MAY re-send the same request to the PCP Server after 30 seconds. If a PCP error response is received, the IGD-PCP IWF relays a negative message to the UPnP Control Point with ConflictInMappingEntry as the error code. NEW: If the requested external port is not available, the PCP server will send a CANNOT_PROVIDE_EXTERNAL error response: 1. If a short lifetime error is returned, the IGD-PCP IWF MAY resend the same request to the PCP Server after 30 seconds without relaying the error to the UPnP Control Point. The IGD-PCP IWF MAY repeat this process until a positive answer is received or some maximum retry limit is reached. When the maximum retry limit is reached, the IGD-PCP IWF relays a negative message to the UPnP Control Point with ConflictInMappingEntry as the error code. 2. If a long lifetime error is returned, the IGD-PCP IWF relays a negative message to the UPnP Control Point with ConflictInMappingEntry as the error code. Better?
