This -scheme for example does not handle situation when the router actually -does not go offline but the network link goes down temporarily. It would -require some intelligence to figure out when it is best time to switch -to the backup router. To make it even more complicated it is possible -that the backup router may have not lost the network link to the primary -router. - -Other possible situation is when the network link is lost temporarily -between two primary routers in the SILC network. Unless the routers -notice the link going down they cannot perhaps find alternative routes. -Worst situation is when the link goes down only for a short period of -time, thus causing lag. Should the routers or servers find alternative -routes if they cannot get response from the router during the lag? -When alternative routes are being found it must be careful not to -mess up existing primary routes between routers in the network. - -It is suggested that the current backup router scheme is only temporary -solution and existing backup router protocols are studied further. It -is also suggested that the backup router specification will be separated -from this SILC specification Internet-Draft and additional specification -is written on the subject. - - .ti 0 4 SILC Procedures
