Embodiment 1

[0114] In the embodiment of this application, in figure 2 A new communication channel is added in the SDN architecture from the SDN controller to the VM manager of the data center system, so that the SDN controller can obtain routing calculation requests through the communication channel.

[0115] Please refer to Figure 6 , the data center system introduced in Embodiment 1 of the present invention includes: VM60, VM manager 61, SDN controller 62;

[0116] VM60 is used to communicate with the opposite end VM and detect the communication quality with the opposite end VM, and report the communication quality information to the VM manager 61 through the interface ①, and the reported communication quality information is specifically shown in Table 3:

Embodiment 2

[0126] In this embodiment, the bearer network of the data center system is still an SDN architecture, please refer to Figure 7, the data center system includes: VM70, VM manager 71, unified orchestration module 72 and SDN controller 73;

[0127] The VM70 is specifically used for: detecting and obtaining the on-off information of the communication path for communicating with the peer VM, as follows:

Abstract

The present invention relates to the technical field of communications. Disclosed are an SDN controller, a data centre system and a router connection method, so as to solve the technical problem in the prior art that a data centre network cannot complete the recovery of communication faults. The SND controller comprises: a receiver used for receiving a routing calculation request sent by an end-point device manager, the routing calculation request carrying information about end-point devices of both communication parties on which routing calculation needs to be conducted; and a processor used for conducting routing calculation on the end-point devices of both communication parties on which routing calculation needs to be conducted, and controlling a forwarding device to conduct router connection on the end-point devices of both communication parties according to the calculated routing information.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an SDN controller, a data center system and a routing connection method. Background technique [0002] Telecom network element cloudification refers to the deployment of traditional telecom network elements and applications based on physical chassis and single boards on general-purpose data center servers in the form of software VM (Virtual Machine: virtual machine) to provide various telecom services to the outside world. , this deployment method is called NFV (Network Functions Virtualization: Network Functions Virtualization) in the industry. In a cloud-based data center, telecom network elements and applications exist in the form of VMs instead of single boards on traditional telecom hardware. The communication between NEs and between different service processes within the same NE is represented as the communication between VMs, such as Figure 1a As shown in FIG. 2 , ...
