We have terrestrial link between korea and us. But we have many down traffic (US -> Korea), we consider satellite for getting more incoming bandwidth. I contacted serveral satellite service providers, but the major concern is integration with existing terrestrial link. Our connection point is located in PAIX(Digital IX). But one candidate is located in Mae-east. My idea is transmitting some traffic into Mae-east via making tunnel. The border router sends incoming mail, ftp, and news traffic into VPN box, which is connected with other port of router. The traffic was encapulated by VPN box. VPN box makes a tunnel with one of Mae-east, which has the similar VPN box configured with our one. The router of mae-east sends traffic into the router of Satellite Service provider. The satellite transmit our traffics... I'll verify my idea is feasible, and there are some reference sites.. Thanks in advance. --J
