Embodiment Construction

[0024] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the system architecture applicable to the embodiments of the present invention will be briefly described below.

[0025] See figure 1 , is a schematic diagram of the architecture of a message forwarding control system provided by an embodiment of the present invention, as shown in figure 1 As shown, in the message forwarding control system, each switching device enables the iSCSI function; where:

[0026] A switching device with local iSCSI client access is called an edge switching device, and a switching device without local iSCSI client access is called an intermediate switching device. The types of iSCSI clients include initiators and targets. For the convenience of subsequent description, the initiator iSCSI client is recorded as an Initiator device, and the target iSCSI client is recorded as a Target device.

[0027] The iSCSI clie...

Abstract

The present invention provides a message forwarding control method and device. The method includes: when obtaining the device information of the iSCSI client, synchronizing the device information of the iSCSI client to the switching device; The area configuration information is synchronized to the neighbor switching device; when the switching device is an edge switching device where an iSCSI client accesses locally, an access control list ACL rule is generated according to the device information of the locally saved iSCSI client and the area configuration information, And according to the ACL rule, forwarding control is performed on the message between the initiator iSCSI client and the target iSCSI client. The application of the invention can realize the hardware-level access control function in the iSCSI network, improve the security of the storage device, and save network and device resources.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a message forwarding control method and device. Background technique [0002] iSCSI (Internet Small Computer System Interface, Internet Small Computer System Interface) is a network storage standard developed by IETF (The Internet Engineering Task Force, the Internet Engineering Task Force), the purpose is to use the IP (Internet Protocol, Internet Protocol) protocol to Storage devices are connected together. Due to the wide application of IP networks, iSCSI can transmit data on LAN (Local Area Network, local area network), WAN (Wide Area Network, wide area network) and even the Internet, so that data storage is no longer restricted by region. [0003] The iSCSI protocol (RFC3720) defines rules and methods for sending and receiving block (data block)-level storage data on a TCP (Transmission Control Protocol) / IP network. The sending end encapsulates SCSI (SmallCom...
