Problems solved by technology

In recent years, due to the introduction of Automatically Switched Optical Network (ASON) technology, users can dynamically apply for bandwidth resources from the optical network through the UNI interface, but this application is still limited to point-to-point serial connections
[0015] In addition, since the transmission capacity of a single optical fiber is much larger than the core capacity of the Internet, the processing capacity of existing routers cannot match the increasing optical transmission speed at all, resulting in the waste of a large amount of optical transmission capacity
If you continue to use the existing serial transmission method, many data-intensive grid applications will not be able to get a fast response and cannot make full use of the bandwidth resources of optical transmission

Embodiment Construction

[0038] exist figure 1 In the illustrated embodiment, a structural schematic diagram of a grid network used in the present invention is given. Such as figure 1 As shown, there are n grid nodes, and the grid nodes communicate through the optical network. The PC of each node has 2 optical interfaces and 2 common network cards. The ordinary network card is used to establish the Gridftp control connection, and the optical interface is used as the interface device for establishing the optical channel for transmitting data.

[0039] In the present invention, the grid resources refer to traditional grid resources other than network resources, such as computing resources, storage resources, data, application programs, various electronic files, and the like. Network resources refer to the facilities that connect each grid resource node and provide data transmission and communication channels between nodes, which can be optical cross-connectors, optical switching devices, optical fibe...

Abstract

This invention discloses an optical parallel transmission method which is open to grid application. When grid users send grid operations to grid server; the server finds the operational grid resources according to grid resource list. According to this grid resource node address inquiry optical network, find the spare available optical network resource; based on the above inquiry result, send one or more optical channel-building requests to optical control layer on demand; after the optical control layer establishes the corresponding optical channel, it returns to the result and updates the list of optical network resource; grid server begin to operate the user submit grid operation; after the operation is finished, it informs optical control layer to close the optical channel links. This invention can solve the capacity demand problem that grid application large bandwidth data transmission, improve the data transmission speed and make full use of the grid network bandwidth resources.

Description

technical field [0001] The invention relates to a method for realizing optical parallel transmission, in particular to a grid application-oriented optical parallel transmission method, which belongs to the technical field of optical communication. Background technique [0002] With the rapid development of national economy, national defense construction and high technology, more and more fields need to solve large-scale scientific and engineering calculations. In order to solve people's actual demand for high-performance computing, people put forward the concept of grid computing in combination with the development of Internet technology. [0003] The grid is a concept borrowed from the power grid, which means that computing power and computing resources can be used just like electricity, "turn on the power switch and use it", regardless of who and how to provide these services. The goal of the grid is to abstract and quantify computing resources, and to complete "quantitat...
