Problems solved by technology

In this way, when the current link between the initiator and the target repeatedly fluctuates and becomes unstable, the basic interaction of iSCSI protocol data can still be carried out because the current link is not interrupted. Use the current link to complete the iSCSI service, but this will cause unstable iSCSI service traffic, affect the execution performance of the iSCSI service, and even cause system paralysis in severe cases, and cannot guarantee the stability and reliability of the iSCSI service execution

Abstract

The invention discloses a method for switching an iSCSI (Internet Small Computer System Interface) session link. The method comprises the following steps: after establishing the iSCSI session link between an initiator and a target, detecting data transmission quality of a current iSCSI session link established between the initiator and the target; judging whether the data transmission quality of the current iSCSI session link meets a preset switching condition; and if the data transmission quality of the current iSCSI session link meets the preset switching condition, switching the iSCSI session link between the initiator and the target. The invention further discloses a device for switching the iSCSI session link. According to the method and the device disclosed by the invention, the stability and the reliability of iSCSI service execution between the initiator and the target are effectively improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for switching an interface session link of a network small computer system. Background technique [0002] The Internet Small Computer System Interface iSCSI (Internet Small Computer System Interface) protocol is a protocol based on the TCP / IP network, which is used to establish and manage the interconnection between IP storage devices, hosts and clients, and create storage areas Network (SAN, Storage Area Network). The storage area network SAN makes it possible to apply the SCSI (Small Computer System Interface, Small Computer System Interface) protocol to a high-speed data transmission network. This transmission is performed between multiple data storage networks at the block-level. [0003] The main function of iSCSI is to perform encapsulation and reliable transmission of a large amount of data between a client (ie, initiator) and a storage device (...
