Photon grid middleware and its control based on optical network resource allocation on demand

Abstract

This invention discloses photon grid middleware which is based on optical network demand allocation and its resource control method. In the middleware, grid service terminal send the resource application to photon grid middleware; G4 application resource management carries on grid-oriented 's resource control and application resource scheduling; middleware packages optical network resource object, according to application resource attribute drive the network resource operation; optical network resource dispatcher uses optical resource scheduling interface to operate grid service-oriented optical resource scheduling, it realizes optical resource's inquiry and scheduling for the grid application and provides the control optical channel for top service; optical network resource supervisor carries on grid-oriented optical resource list management; optical control layer provides the establishment of the signaling mechanism, based on routing algorithm choose the suitable routing, and realize the optical access control through GUNI. This invention can realize dynamic bandwidth allocation of grid application data transmission based on the grid service's driving to optical network.

Description

technical field [0001] The invention relates to a photon grid middleware oriented to a grid system and based on an on-demand allocation mechanism of optical network resources, and also relates to an optical network resource control method realized by using the photon grid middleware, belonging 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] Grid is a concept borrowed from power grid. Its earliest origin comes from "metacomputing", which is the predecessor of computing grid. Its goal is to organize expensive high-performance computers distributed in various places to realize...

AI Technical Summary

Problems solved by technology

The function of the existing grid middleware mainly lies in the management of jobs, data, files, information and equipment resources. Its functions are limited to the application layer services and cannot provide network layer-oriented resource services for grid users. This will Make grid applications alternate between bandwidth shortage and idle bandwidth

Namely: when the data volume of the grid operation is large and the load is heavy, the users in the existing grid need to apply for a larger bandwidth from the network provider or establish their own private network, which requires a long cycle and often cannot be completed in a timely manner. Meet the needs of users

Once the bandwidth is satisfied, the grid operation may no longer need such a large bandwidth, which will cause idle and waste of resources

[0014] On the other hand, with the development of Internet services, the diversification of business forms carried by communication networks has led to the expansion of bandwidth requirements.
