Abstract
A deficiency in a link in a messaging system is detected by sending across the link a request message that includes a coded data string, receiving across the link a reply message that includes the coded data string, and determining whether the travel time involved is excessive. To maximize the likelihood that the coded data string is included in the reply message, the coded data string is preferably included in both the subject and body fields of the request message.
