Embodiment Construction

[0024] In order to effectively reduce the number of retransmitted messages and meet the requirement of zero packet loss when continuous topology changes occur in the ring network, the present invention provides a method and device for sending Goose messages in the ring network.

[0025] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] figure 1 A schematic diagram of the sending process of a Goose message in a ring network provided by the embodiment of the present invention, the process includes the following steps:

[0027] S101: An ordinary node device in the ring network receives a Goose message through a first ring port, and identifies sequence identification information carried in the Goose message.

[0028] Specifically, in the embodiment of the present invention, the node devices in the ring network are divided into ordinary node devices and intervening (GAP) node devices. Ordinary node devic...

Abstract

The invention discloses a method and a device for sending a Goose message in a ring network. The method comprises the following steps: when ordinary node equipment receives the Goose message via a ring port, identifying sequence identification information carried in the message in order to judge whether or not the message is continuous; when the message is judged to be continuous, forwarding the Goose message; if the message is judged to be discontinuous, judging whether or not the Goose message is received before; if the Goose message is determined to be received before, forwarding the message; and when the Goose message is determined to be not received before, creating a Goose message request for requesting next sequence identification information, and sending the Goose message request. Only the Goose message which is not received before is requested when the received Goose message is determined to be discontinuous according to the sequence identification information carried in the Goose message, so that the requirement of zero packet loss during continuous topological change of the network can be met. Meanwhile, the problem of Goose message loss is solved by increasing the utilization ratio of the cache of a node saved message.

Description

technical field [0001] The invention relates to the technical field of industrial Ethernet, in particular to a method and device for sending Goose messages in a ring network. Background technique [0002] The general object-oriented substation event (Goose) is a mechanism to meet the fast message requirements of the substation automation system. The Goose message sent can facilitate the operator to monitor, measure and analyze the status of all aspects of the network. [0003] Current ring network protocols such as DRP can help users automatically cut redundant links in the network, prevent packet storms in the ring network, and also ensure that redundant links can be restored according to actual conditions when the network changes. However, the new network topology needs a certain period of time to stabilize. During this period of time, the DRP protocol cannot guarantee the zero packet loss requirements of the packets in the ring network. Therefore, in order to increase the...
