May I know what are the problems associated with operating a switched LAN? Erick 16-September-2007 06:00:19 PMComments this site help u www.sinclair.org.au/keith/networking/technical-answers.html - 16k - Posted by waqasahmad A switched LAN (Local Area Network) may use a Gigabit Ethernet switch that includes different ports connected to PCs and to layer 3 routers. The routers connected to different switch ports can not immediately identify failures either of other routers or of the ports and links by which they are connected to the switch. The routers currently have to rely on slow timeout mechanisms, such as missed hello packets, to detect failures on other links connected to the switch. Thus, the time required to detect failures can and often does dominate the time required for a routing algorithm to determine a new network topology around a detected failure (convergence time).
