Example Embodiment

[0113] Example one

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

[0115] Please refer to Image 6 , The data center system introduced in the first embodiment of the present invention includes: VM 60, VM manager 61, and 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 communication quality information to the VM manager 61 through the interface ①. The reported communication quality information is specifically shown in Table 3:

[0117] table 3

[0118] Endpoint devices

[0119] Time delay information (ms)

[0120] The VM manager 61 filters out the endpoint devices of the communication parties corresponding to the delay information who...

Example Embodiment

[0125] Example two

[0126] In this embodiment, the bearer network of the data center system is still 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 to detect and obtain the on-off information of the communication path communicating with the peer VM, as follows:

[0128] Endpoint devices

[0129] Then VM70 determines that the communication quality of VMa does not meet the preset communication quality requirements, so the identification information of the endpoint devices of the communicating parties that do not meet the preset communication quality requirements is reported to the VM management through the interface ①: [VM70, VMa] 器71;

[0130] The VM manager 71 is specifically configured to obtain the topological location information of [VM70, VMa] after receiving the [VM70, VMa] reported by the VM70, and then obtain the routing calculat...

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 , ...
