<P>PROBLEM TO BE SOLVED: To lighten the processing load of a server associated with network connection control. <P>SOLUTION: When a connection request from a user terminal or a broadband router is accepted, an invalid request determination unit determines whether the number of times a connection request from the user terminal or the broadband router is found invalid exceeds a prescribed threshold. When the number of times a connection request is found invalid is determined to exceed the prescribed threshold by the invalid request determination unit, a connection destination LNS response unit exerts control so that an invalid connection accommodation LNS and an LAC not connected to an ISP enterprise network are connected by a layer-2 tunneling protocol. <P>COPYRIGHT: (C)2013,JPO&INPIT |
