1. A tunnel adds 44 bytes to a client packet, so a network whose packets average 300 bytes carries roughly 15 percent more overall, which a campus backbone treats as slight.
2. A tunnel adds 44 bytes to a client packet, so a network whose packets average 300 bytes carries roughly 50 percent more, which a campus backbone treats as a heavy load.
3. A tunnel adds 44 bytes to a client packet, so a network whose packets average 1500 bytes carries about 3 percent more, which a campus backbone treats as slight.
4. A tunnel adds 300 bytes to a client packet, so a network whose packets average 44 bytes carries several times more, which a campus backbone treats as a heavy load.
