Problems solved by technology

The process of encapsulation and decapsulation will generate a lot of calculations; the increase of data length caused by the encapsulation process will occupy more network bandwidth
Therefore, using the traditional message communication method to keep the system alive will generate more system overhead

Embodiment Construction

[0032] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] A chassis LAN system usually consists of multiple system board modules. These board modules can roughly be divided into a main control module and a sub-control module, and the main control module is mainly responsible for keeping alive information in the system (such as whether each block module is online or not) in the process of realizing the system keeping alive method based on Ethernet multicast of the present invention. , whether it is running normally), command issuance (such as ordering the standby module to replace the faulty module) and decision-making control (such as judging whether the decision-making sub-control module fails, and whether an alarm needs ...

Abstract

The invention discloses a system keep-alive method based on Ethernet multicast, mainly relating to the network keep-alive field. The system keep-alive method comprises the steps: using a master control module to periodically poll a sub-control module, and updating the system keep-alive information according to the response situation of the sub-control module; replacing a fault sub-control module by a backup sub-control module; using the backup sub-control module to report the state to the master control module; and using the master control module to update the system keep-alive information according to the state reported by the backup sub-control module. The invention provides the system keep-alive method based on Ethernet multicast, which is less in system overhead. The communication process of the method belongs to data link layer communication, and the treatment process is less in calculation amount, network bandwidth occupation and the system overhead.

Description

technical field [0001] The invention relates to the field of network system keeping alive, in particular to a system keeping alive method based on Ethernet multicast. Background technique [0002] A communication system, such as a chassis LAN system, usually consists of multiple system board modules, and also has multiple communication ports and communication links. In order to ensure the long-term uninterrupted operation of the system with a small failure interval Exist in the system at the same time in a redundant manner, and perform mutual backup or load sharing to improve equipment reliability. The system needs to refresh information about the presence and operation of each module in real time. If the module is running normally, we call it in the "alive" state; alive" status. At present, Ethernet is one of the most commonly used technologies for interconnection among modules within the system. [0003] There are two main ways to obtain whether the internal modules of ...
