Embodiment Construction

[0035] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Figure 5 It is a schematic flow chart of the method described in the present invention, in which method, an optimal route selection is performed for anycast attribute services through a hybrid single-route / multi-route transmission scheme. In multi-route transmission, the best transmission scheme is selected for anycast attribute services by constructing the maximum flow minimum cost model suitable for cloud computing data center optical network. When weighing the network energy consumption and blocking rate, factors such as the utilization rate of spectrum resources and the working status of nodes and links are considered comprehensively, and business grooming technology is considered to improve the utilization rate of optical transceivers and spectrum resources.

Abstract

The invention relates to an energy-saving routing method for anycast attribute services, and belongs to the technical field of energy-saving optical network of cloud computing data center. This method optimizes route selection for anycast attribute services through a hybrid single-route / multi-route transmission scheme; in multi-route transmission, by constructing an energy-saving routing method based on the maximum flow and minimum cost for cloud computing data center optical networks, the method provides optimal routing for anycast Select the best transmission scheme for attribute services; when weighing network energy consumption and blocking rate, comprehensively consider the utilization rate of spectrum resources and the working status factors of nodes and links, and consider business grooming technology to improve optical transceivers and spectrum resource utilization. The method can effectively reduce the overhead of the optical transceiver and the protection bandwidth, thereby reducing network energy consumption and improving spectrum resource utilization.

Description

technical field [0001] The invention belongs to the technical field of optical network energy saving in cloud computing data centers, and relates to an energy-saving routing method for anycast attribute services. Background technique [0002] IP services in the cloud computing data center network are increasing day by day. This brings business diversity and end-to-content characteristics, which urgently require that the optical network as a basic transmission facility can perform business transmission flexibly, quickly and reliably. In recent years, the Elastic Optical Network (EON) proposed based on OFDM technology is very suitable for data center network scenarios due to its advantages of high bandwidth, on-demand allocation of resources, and flexible scheduling. Anycast refers to a service in which the source node is fixed and the destination node is not fixed. Such services include cloud computing services, content distribution network services, grid computing, distrib...
