ISCSI cross-layer system

The invention discloses an iSCSI cross-layer system, and relates to the technical field of network storage. The SCSI-iSCSI-TCP module comprises an Application module, an SCSI module, an iSCSI module, a TCP module, an IP module, an MAC module and the like, and particularly, the SCSI module, the iSCSI module and the TCP module are combined and optimized to design the SCSI-iSCSI-TCP module. According to the cross-layer design method, the influence of the network on the iSCSI target device is small, and the cross-layer design method can be applied to the network in a poor state; and the influence of the protocol stack layering on the iSCSI target device is small, so that the influence of the environment on the iSCSI target device is small, and the method can be applied to a long-distance network environment. And meanwhile, the system has the advantages of low hardware cost, simplicity in operation, convenience in maintenance, high expandability and the like. The method can be widely applied to various iSCSI syste
