In addition, any traffic along the TCP path between the two tunneling routers will cause varying delays, etc. Since TCP provides no guarantees about rate of delivery and jitter, tunneling the UDP packets through a TCP connection is probably a bad idea. 2) Routers would be the best choice, because: a) The network contains several circuits, so the use of routers will prevent packets from traveling in circles around the network, because the routers will choose intelligent paths for packets to follow. b) Using routers allows the isolation of broadcast storms caused by a malfunctioning host on the neetwork. 3) AS9: Use static routing within and between Ases since the AS is extremely simple and has only one AS connected to it.
