Abstract:
1. A data relay system having a logical tunnel established within a specified public network interposed between a specified backbone network and host devices, which relays data between the backbone network and the host devices through the logical tunnel, the system comprising: a first data relaying apparatus, disposed within the specified public network, for relaying data between the backbone network and the host devices through the logical tunnel established within the public network, the data relaying apparatus comprising when the data loaded from said host device is the predetermined control packet, the first data relaying apparatus performs control processing so as to relay the data without routing through the logical tunnel; a second data relay apparatus, disposed within the specified public network for relaying data between the backbone network and the host devices said second data relay apparatus comprising a third data relay apparatus, disposed within the a specified public network, for relaying data between the backbone network and said host devices, said second data relay apparatus comprising wherein said second control processing unit of said third data relay apparatus performs control processing so as to relay the data, as a target to be controlled stored by said storage control unit of said first data relay apparatus, to said host device that has issued a specified reception request.
