Embodiment Construction

[0057] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0058] When ENode and FCF are connected through FSB, FSB needs to maintain the virtual link between VN_Port on ENode and FCF to form a session list. When there is a problem with the virtual link, such as ENode disconnection or FCF disconnection, FSB needs to release itself for these Access Control List (English: AccessControlList, ACL for sho...

Abstract

The invention provides a link keep-alive method and device. An FSB analyzes a discovery announcement message sent by an FCF to an ENode to obtain a first period, wherein the first period is a link keep-alive period of a virtual link between a virtual node port VN_Port arranged on the ENode and the FCF; the FSB determines a second period according to the first period; and if not receiving any Fibre Channel over Ethernet initialization protocol FIP message, the FSB determines link disconnection of a virtual link between the virtual node port VN_Port and the FCF. By adopting the link keep-alive method and device provided by the embodiment of the present invention, function abnormality caused by improper setting of the second period can be avoided.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method and device for link keeping alive. Background technique [0002] Fiber Channel over Ethernet (English: FibreChanneloverEthernet, referred to as: FCoE) is a converged network technology defined by the American National Standards Institute (English: American National Standards Institute, referred to as: ANSI). Protocol-based input and output integration solutions. In traditional data center networking, a local area network (English: LocalAreaNetwork, referred to as: LAN) is used for communication between servers and servers and between clients and servers, and a storage area network (English: StorageAreaNetwork, referred to as: SAN) is used for servers and storage devices. communication between. LAN and SAN are deployed and maintained independently of each other. With the rapid development of data centers and the surge in the number of servers, the independent deploym...
