Embodiment Construction

[0022] In order to better understand the technical solution of the present invention, a detailed introduction will be given below in conjunction with the accompanying drawings.

[0023] 1. Abstraction of Physical Topology

[0024] Use the method of Full-mesh to abstract the network topology. It reduces the physical topological nodes to an abstract topology that only leaves boundary nodes. A border node is a node connected to other network domains in its own network domain.

[0025] The physical topology of the network is represented by G(V,E), where V={v n} represents the node of the network, E={e (u,v) |(u,v)∈V 2} represents the edge of the topological graph. ||V||=N represents the number of nodes, ||E||=L represents the number of edges, B (u,v) represents side e (u,v) bandwidth, in bytes per second. The abstraction of physical topology is to represent the topological graph G(V,E) by its subset G'(V',E'), where V'={v b} is the collection of boundary nodes of topology...

Abstract

The invention discloses a resource quantitative distribution method based on an optical network architecture service plane, which comprises the steps of reducing physical topology nodes into abstract network topology with only boundary nodes being left in physical network topology; enabling links of different target-source node pairs in the abstract network topology to share the same practical link, wherein different practical links can be selected to carry out data transmission of the links of the target-source node pairs, and the data flow of each practical link can be only along the same direction; calculating a bandwidth value of a shortest path between each internal node and all of the boundary nodes in the physical topology, and merging the internal node to the boundary node corresponding to a maximum value of the bandwidth value. According to the invention, linear constraint conditions are defined, bandwidth resources of all links are sufficiently considered, thereby not only being high in resource request hit ratio, but also fully integrating scattered bandwidth resources, and enabling the utilization ratio of the resources to be improved correspondingly.

Description

technical field [0001] The present invention abstracts and allocates network resources and IT resources based on a service-oriented optical network architecture, and specifically relates to the abstraction of network physical topology and the quantitative allocation algorithm of related resources. Background technique [0002] In recent years, the Internet business has achieved tremendous development, and the number of network-based application services and users is also increasing rapidly. However, various network applications and huge user scale bring severe challenges to the development of optical Internet technology. These challenges mainly include: coordination of network resources and IT resources (computing resources and storage resources), high service reliability required by users, diversity and scalability of network services, etc. [0003] In order to meet such challenges, the optical network adds a service plane on the basis of the original three-layer architect...
