Embodiment Construction

[0020] 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.

[0021] See figure 1 , is a schematic diagram of the architecture of a device management system provided by an embodiment of the present invention, as shown in figure 1 As shown, in the device management system, each switching device enables the iSCSI function and supports the iSNS protocol; where:

[0022] If a switching device deploys iSNS Server, and there is no other switching device deploying iSNS Server between the switching device and at least one iSNS Client, the switching device is called an edge switching device;

[0023] Wherein, the at least one iSNS Client may be called an iSNS Client locally accessed by the edge switching device;

[0024] If a switching device is deployed with iSNS Server, and there are other sw...

Abstract

The present invention provides a server discovery method and device. The method includes: the switching device deployed with the Internet storage name service protocol iSNS server Server determines the iSNS Server used for device management; the edge switching device broadcasts messages to the local connection The imported iSNS Client notifies the IP address of the iSNS Server used for device management. Application of the invention can avoid introducing independent application server, simplify network deployment, and realize automatic discovery of iSNS Server.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a server discovery 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] iSCSI adopts Client (client) / Server (server) working mode. The client side acts as an Initiator (initiating) device to initiate an iSCSI session, corresponding to the server. The Server serves as a Target (target) de...
