Problems solved by technology

However, this architecture has two main deficiencies: on the one hand, the architecture can be expanded by increasing the number of WSSs, but as the network architecture expands, the diameter of the network architecture also increases; on the other hand, the architecture cannot Good support for traffic localization
The reason for these two problems is that the single-hop routes of service node pairs are too few, the average route is too long, and the probability of service being blocked is high.

Embodiment Construction

[0019]In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] Implementation:

[0021] This embodiment is based on the figure 2 The optical network architecture inside the data center and figure 1 The network components shown are described. Mainly explain the construction method of the optical network architecture inside the data center. The specific workflow of this implementation is as follows:

[0022] 1. According to the number of WSS ports N, calculate the required N+1 BCUs, N x (N+1) WSSs. exist figure 2 Among them, N is 4, a total of 5 BCUs are required, and a total of 20 WSSs are required.

[0023] 2. Group N x (N+1) WSSs into N+1 group...

Abstract

The invention discloses a WSS (Wavelength Selective Switch)-based extensible architecture for an internal network of a data center supporting flow localization. The architecture comprises internal interconnection and external interconnection of BCUs (Basic Construction Unit) formed by WSSs, and interconnection of network components thereof. The architecture is simple to implement and can be realized by a commercial WSS device, and the architecture has strong practicability and good extendibility, so that a problem of growth of a network diameter during extension of a ring network structure is overcome, and the architecture supports a cloud service communication mode and flow localization.

Description

technical field [0001] The invention relates to the technical field of communication, and is a WSS (wavelength selective switch)-based internal network architecture of a data center. This architecture is mainly used in the internal network of the data center. It is a network architecture that supports traffic localization and has good scalability. It can effectively cope with the exponential traffic growth inside the data center and reduce the energy consumption of the data center. Background technique [0002] As the mainstream model of next-generation Internet services, cloud services mobilize various resources in the network, migrate applications, storage and computing resources on the Internet to the data center, and provide users with personalized, low-cost and efficient services. An important development trend of the Internet in the future will also become the core of the modern service industry. The data center is an important carrier of informatization that is indis...
