Problems solved by technology

When the network traffic is large or other special circumstances occur, the insufficient processing capacity of individual devices will increase the processing delay, reduce the efficiency of Goose packet filtering, and even cause the system to crash
At the same time, when the relevant filtering configuration needs to be modified or updated, it needs to be updated and maintained one by one, which will consume a lot of manpower and time resources

Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, a kind of SDN-based Goose message flow table filtering method of the present invention is specifically as follows:

[0025] Configure two flow entries in the controller, and all packets entering the specified port will match the contents of these two flow entries in turn. When a packet matches both flow entries, it is a Goose packet. When the packet cannot match any of the flow entries, it is a non-Goose packet.

[0026] (1) Configure the first flow entry of the flow table in the controller. Set the input port 1 (eg ingress port=1), set the destination MAC address between 0x010CCD010000 and 0x010CCD0101FF, and set the Ethernet type to 0x8100.

[0027] (2) Configure the Action of the first flow entry. When the message passing port 1 satisfies step (1), set the vlan id (such as vlan id...

Abstract

The invention relates to an SDN-based Goose message flow table filtering method, the method comprising (1) configuring the first flow table item of the flow table in a controller; (2) judging whether the message matches the first flow table (3) configure the second flow entry of the flow table in the controller; (4) determine whether the packet matches the second flow entry. The present invention dynamically configures the filtering of Goose messages through the SDN-based flow table. This method can improve the real-time performance of Goose message filtering, and effectively improve the operation and maintenance efficiency of updating configuration information.

Description

technical field [0001] The invention relates to a message flow table filtering method, in particular to an SDN-based Goose message flow table filtering method. Background technique [0002] The general object-oriented substation event (Goose) is a multicast communication mechanism used by the IEC 61850 standard to solve real-time signal communication between intelligent electronic devices (IED). The smart substation adopts the IEC 61850 unified communication protocol, which is usually divided into process layer, bay layer and station control layer. Bay layer and station control layer equipment, process layer and bay layer equipment are interconnected through a communication network, and are used to control switch tripping and closing. Messages are transmitted over this communication network, so its timeliness is critical. [0003] Currently commonly used Goose packet filtering methods are based on the static configuration of the switching device, that is, each filtering con...
