Optical Network Resource Management Method Based on Multidimensional Frame Mapping

Abstract

The invention discloses an optical network resource management method based on multi-dimensional frame mapping. By means of the optical network resource management method, the dynamic performance and the real-time performance of scheduling resources are improved. Under the conditions of complex network topology and arrival of a multitask request at an optical path established in a network, the optical network resource management method comprises the following steps that firstly, an optical network resource model is established; secondly, information of all links in sub-domains is collected; thirdly, a frame module set is established; fourthly, the optical path of a task request of a user is established, a request packet is formed according to occupied resources, a path is established, and available optical network resources are obtained; finally, when the optical path established for the task request occupies a channel or data transmission is over, automatic update of the resources is completed immediately. The optical network resource management method based on multi-dimensional frame mapping provides a unified optical network resource management and representation mode for a multi-network management system in a current communication network, realizes intercommunication and interconnection between optical networks in different network systems in different regions, enables different network management systems to realize cross call of public resources, and increases the utilization rate of existing optical network resources.

Description

technical field [0001] The invention relates to the technical field of optical network resource management, in particular to an optical network resource management method based on multi-dimensional frame mapping. Background technique [0002] Optical network is the basic transmission platform of modern communication. With the rapid development of large-scale data centers and cloud computing, optical network transmission data is growing explosively, and the real-time and high-efficiency requirements for optical network resource allocation are getting higher and higher. How to realize the condition of limited wavelength and optical fiber load capacity Realizing data transmission to the greatest extent is one of the main problems faced by the development of optical network technology. At present, the construction, investment and use of 4G networks are in the ascendant. A business has proposed a vision for 5G networks to achieve higher upload / download speeds. This move will le...

Problems solved by technology

RSL is only used to describe resource requests and computing resources in Globus, and cannot describe other resources, and the scope of use is too small

WSDL (Web Service Description Language) is mainly used to describe the capabilities of computing, storage and other resources. It abstracts its functions into specific values ​​by shielding the differences of the described objects; however, the definition of its elements and attributes is limited, and its scalability is poor.

[0005] To realize the description and resource scheduling of optical network resources through computer language, it is first necessary to use the corresponding computer language to define each element, and to translate the actual state of optical network resources into computer language, and the computer language needs to be translated into machine language again. Its implementation process is complicated, and its calculation complexity is high. Its resource description method and update mode are not enough to guarantee the QoS guarantee for users to establish optical paths.

Especially after the introduction of the ASON control plane, resources are scheduled from a global perspective, and the requirements for real-time and dynamic updates of optical network resources are getting higher and higher; at the same time, in the resource description of ASON, the relevant manufacturers currently do not have a unified and effective method for each other. The resource description method realizes fast resource scheduling, which makes the efficiency of resource scheduling relatively low, and the accuracy of resource response and real-time dynamics of resources are poor.
