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 Goose messages in a ring network. When an ordinary node device receives a Goose message through a ring port, it will identify the sequence identification information carried in the message to determine whether the message is continuous. When it is judged that the message is continuous, it will forward the Goose message; Receive the Goose message, forward the message when it is determined that it has received the message, and create and send a Goose message requesting the next sequence identification information when it is determined that it has not received the message. Because in the invention, according to the sequence identification information carried in the Goose message, when it is determined that the received Goose messages are discontinuous, only the Goose messages that have not been received by itself are requested, so zero packet loss can be satisfied when the continuous topology of the network changes requirements, and at the same time solve the Goose message loss problem by improving the utilization rate of the cache where the node saves the 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...
