Note: When an application is started, the first packet transmission occurs after a delay equal to (packet size/bit rate). Note also, when an application transitions into an off state in between packet transmissions, the remaining time until when the next transmission would have occurred is cached and is used when the application starts up again. Example: packet size = 1000 bits, bit rate = 500 bits/sec. If the application is started at time 3 seconds, the first packet transmission will be scheduled for time 5 seconds (3 + 1000/500) and subsequent transmissions at 2 second intervals. If the above application were instead stopped at time 4 seconds, and restarted at time 5.5 seconds, then the first packet would be sent at time 6.5 seconds, because when it was stopped at 4 seconds, there was only 1 second remaining until the originally scheduled transmission, and this time remaining information is cached and used to schedule the next transmission upon restarting.
