Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0029] A simulation method for large-scale scenarios of power communication optical transmission network, such as figure 1 shown, including the following steps:

[0030] A: Establish a link model with transmission attributes, the link model is used to simulate the service forwarding path in the optical transmission network, and use the link model to simulate the optical transmission network.

[0031] Specifically, the optical transmission network is a transmission network that carries power communication services. It is built by SDH and OTN technologies. The network bandwidth is highly redundant, and the delay and error code are stable. The forwarding path of each service from the...

Abstract

The invention provides a simulation method and system for a large-scale scene of an electric power communication optical transmission network. The simulation method comprises the following steps: A: establishing a link model with transmission attributes, and simulating the optical transmission network by using the link model; B: simulating a fault; C: obtaining fault information, calculating a newservice forwarding path after network self-healing protection according to the fault information and pre-stored forwarding path information, and calculating corresponding new transmission attributesof the link model according to a new service forwarding path; and D: updating the link model according to the new transmission attributes. According to the simulation method and system for the large-scale scene of the electric power communication optical transmission network provided by the invention, the service forwarding path in the electric power communication optical transmission network is abstracted as the link model with small fluctuation of delay and error code, the self-healing protection of the fault in the electric power communication optical transmission network is abstracted as the switching of the link model, so that the simulation of the large-scale scene can be completed in a single simulation software.

Description

technical field [0001] The invention relates to the technical field of communication network simulation, in particular to a simulation method and system for a large-scale scene of an electric power communication optical transmission network. Background technique [0002] The power communication network is a relatively professional communication network, which is composed of the transmission system connected to the power plant to the substation and the power departments at all levels, and the switching system or terminal equipment in these departments. It is an important part of the power grid. component. [0003] There are two main requirements of power automation for power communication network: reliability and timeliness. [0004] Reliability requirements mean that important messages transmitted on the network will not be lost due to collisions or other reasons between nodes competing to send messages, and that reliable transmission can be ensured by means of retransmissi...
