Embodiment Construction

[0051] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0052] refer to figure 1 , an industrial SDN-oriented dynamic network resource reservation QoS guarantee method of the present invention includes a reserved resource application process, a reserved resource forwarding process and a reserved resource release process. Reservation / release of resources is initiated by the terminal device, and the application information enters the network controller through the SDN network control channel through the switch connected to the terminal, and resource scheduling planning is performed in the controller, and the feedback result is returned to the terminal device through the flow table. The bold line in the figure indicates the direction of the reserved / release resource negotiation data, and the dotted line indicates the control channel data.

Abstract

The invention discloses a dynamic network resource reservation QoS guaranteeing method oriented to an industrial SDN. The method comprises a reserved resource application process, a reserved resource forwarding process and a reserved resource releasing process. A data packet with a designated Ethernet type is used for performing the negotiation of the resource reservation between a terminal device and a network, a network switch connected with the terminal intercepts the data packet of this type and sends the same to a controller; the controller reserves a bandwidth resource for the data flow according to the bandwidth and delay requirement of the data flow and the actual application condition of the network bandwidth, or releases the reserved bandwidth resource, and delivers the reserved resource result to the switch in a flow table sending way to be executed. The resource reservation / releasing process is flexibly controlled through a negotiation mechanism, and the supportability on the service data flow especially the period service data flow and the adaptability on the complicated communication state by the network can be improved.

Description

technical field [0001] The invention belongs to the technical field of data communication, and in particular relates to an industrial SDN-oriented dynamic network resource reservation QoS guarantee method. Background technique [0002] With the development of Internet technology, the application of software-defined network (SDN) is more and more extensive. Different from traditional networks, software-defined networks adopt a structure that separates control and forwarding, and can re-plan the network with programs in a centrally controlled manner without changing hardware devices. Therefore, the cost of network deployment is reduced, and the burden of network operation and maintenance is reduced. [0003] During the transmission of network data, there are often defined requirements for bandwidth and delay. Especially for some periodic services, the requirements for bandwidth and delay are relatively fixed. Burst data traffic often impacts the network, causing the network ...
