Embodiment Construction

[0024] To enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention, the following briefly describes the system architecture to which the embodiments of the present invention are applicable.

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

[0026] Switching devices with iSCSI client access locally are called edge switching devices, and switching devices without iSCSI client access locally are called intermediate switching devices. Among them, the types of iSCSI clients include initiator and target. For the convenience of subsequent description, the initiator iSCSI client is recorded as the Initiator device, and the target iSCSI client is recorded as the Target device.

[0027] The iSCSI client ...

Abstract

The invention provides a message transmitting control method and device; the method comprises the following steps: when the equipment information of an iSCSI client is acquired, the equipment information of the iSCSI client is synchronized to switching equipment; when the region configuration information is acquired, the region configuration information is synchronized to neighbor switching equipment; when the switching equipment is the edge switching equipment which is locally accessed by the iSCSI client, an access control list ACL rule is generated according to the locally stored equipmentinformation of the iSCSI client and the region configuration information; and transmitting control is performed on the message between the initiator iSCSI client and the target iSCSI client accordingto the ACL rule. According to the method and the device in the invention, the access control function of a hardware level in the iSCSI network can be realized, the security of the storage equipment isimproved, and network and equipment resources are saved.

Description

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