The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described are capable of operation in sequences other than those illustrated or otherwise described herein.
Moreover, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or modules is not necessarily limited to those steps or modules explicitly listed, but may include other steps or modules not expressly listed or inherent to such process, method, article, or apparatus.
For ease of understanding and illustration, the method, apparatus, device and medium for configuring the IEC 61850-based TSN network provided in this embodiment are described in detail below with reference to fig. 3 to 8.
In one embodiment, as shown in fig. 3, there is provided an IEC61850 based TSN network configuration method, including the following steps:
s101, analyzing a Substation Configuration Description (SCD) file, wherein the SCD file comprises a total station virtual connection relation and a stream attribute.
For example, in the embodiment of the present application, stream attributes of each virtual connection are obtained by parsing elements such as Inputs/ExtRef in an SCD (Substation Configuration Description) file, which may include but is not limited to a transmission period, a source transmission time window, a destination reception time window, a deterministic requirement such as time delay dispersion, and the like. The information may be carried by a desc attribute of the Inputs/ExtRef element, and may also be carried by a Private tag. In addition, the embodiment of the present Application may further obtain a corresponding relationship between the publisher and subscriber by analyzing, for example, the Inputs tag, and extract a corresponding relationship between the idname and APPID (Application Identifier).
S102, acquiring the network topology of the TSN switches, and determining the corresponding relation between an application identifier (APPID) and a port number of each Intelligent Electronic Device (IED) directly connected with each TSN switch.
The IED refers to an Intelligent Electronic Device (Intelligent Electronic Device). The TSN (Time Sensitive Network) technology can solve the problems of Network real-Time performance and certainty by a series of operations such as clock synchronization (IEEE 802.1 as), traffic scheduling (IEEE 802.1 Qbv), stream preemption (IEEE 802.1 Qbu), stream shaping (IEEE 802.1 Qav), traffic monitoring (IEEE 802.1 Qci), stream reservation (IEEE 802.1 Qat), and the like, and improve the power scene speed. Meanwhile, the TSN technology also satisfies an industrial scenario in which it (information technology) and ot (operation technology) are integrated, and can implement common network transmission of SV, GOOSE, MMS, and IEEE1588 messages.
And S103, performing end-to-end flow model analysis and scheduling calculation based on the total station virtual connection relation, the flow attribute and the corresponding relation between the application identifier (APPID) and the port number of the intelligent electronic device IED, and generating configuration information.
For example, in the embodiment of the present application, a total station flow forwarding path table is first generated according to a total station virtual connection relationship and a flow attribute, and a redundant alternative path may also be generated at the same time, for example, the path division manner may include, but is not limited to, technologies such as vlan (virtual Local Area network) and open flow table; then, generating a flow demand table of each TSN switch according to a corresponding relation between an application identifier (APPID) of the flow forwarding path table and the intelligent electronic device IED and a port number; further, according to the flow demand table, configuration information of each TSN switch is calculated, for example, the configuration information may include, but is not limited to, at least one of a flow scheduling parameter Qbv, a flow preemption parameter Qbu, and a flow monitoring parameter Qci. Because the problem relates to global optimal path planning, the shortest path and the redundant alternative path can be calculated by adopting a shortest path algorithm such as Dijkstra and the like, and after the flow path is determined, scheduling algorithms such as greedy algorithm, short job priority, highest demand priority (shortest delay) and the like or AI auxiliary and the like can be adopted to realize the TSN time slot configuration calculation of each switch on the flow path.
