Problems solved by technology

[0003] However, in the process of relying on manual service configuration, especially after the service is withdrawn or deleted, there will be many unoccupied bandwidth fragments in the links occupied by the service. In order to make full use of these bandwidth fragments, operators usually It takes a lot of time and manpower to adjust services through manual cutover, which reduces OTN bandwidth occupancy and affects OTN resource utilization.

Embodiment Construction

[0024] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0025] In the description of the present invention, unless otherwise specified, " / " means "or", for example, A / B may mean A or B. The "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone These three situations. In addition, "at least one" means one or more, and "plurality" means two or more. Words such as "first" and "second" do not limit the number and order of execution, and words such as "first" and "second" do not necessarily limit the difference.

[0026] In the following, the inventive concept of the present invention is introduced: at present, in the maintenance and management process of the OTN, aft...

Abstract

The invention discloses a service processing method and a software defined network (SDN) controller, relates to the technical field of communication, and is used for adjusting an optical transport network (OTN) service. The method comprises the steps of detecting whether an optical transport network OTN link between a first node and a second node has available bandwidth or not; when the availablebandwidth exists in the OTN link, determining one or more services to be adjusted according to the available bandwidth of the OTN link, wherein the OTN link is not used by the one or more to-be-adjusted services, the transmission path of the one or more to-be-adjusted services comprises the first node and the second node, the bandwidth occupied by one service to be adjusted is less than or equal to the available bandwidth of the OTN link, or the sum of the bandwidths occupied by the plurality of services to be adjusted is less than or equal to the available bandwidth of the OTN link; and migrating the one or more services to be adjusted to the OTN link. The embodiments of the invention are applied to an optical transport network OTN.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a service processing method and a software defined network (Software Defined Network, SDN) controller. Background technique [0002] At present, when operators' operation and maintenance personnel configure services in the Optical Transport Network (OTN), they usually need to manually check link resources. After determining the available bandwidth and other resources between the source node and the target node of the service to be , to create or adjust services. [0003] However, in the process of relying on manual service configuration, especially after the service is withdrawn or deleted, there will be many unoccupied bandwidth fragments in the links occupied by the service. In order to make full use of these bandwidth fragments, operators usually It takes a lot of time and manpower to adjust services through manual cutover, which reduces the bandwidth occ...
