Method and device for data transmission adjustment of transport network

Abstract

The embodiment of the invention discloses a method and a device for data transmission adjustment of a transport network and belongs to the field of optical communications. The method comprises the following steps: receiving information for adjusting the designated optical transfer network (OTN) line, which is transmitted by the OTN; adjusting the OTN line corresponding to the information for adjusting the designated OTN line; calculating the changed data flow rate according to the information for adjusting the designated OTN line; designating an Ethernet channel which needs adjustment according to the changed data flow rate; and correspondingly adjusting the Ethernet channel which needs adjustment. The device comprises a link capacity adjustment scheme (LCAS) module and a channel processing module. By relating the OTN line adjustment to the Ethernet channel adjustment, the embodiment of the invention ensures the effectiveness of data transmission and enhances the overall performance ofthe network.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a method and device for adjusting transmission network data transmission. Background technique [0002] As the core technology of the next-generation transport network, OTN (Optical Transport Network) has rich operation, management, and maintenance (Operation Administrator Maintenance, OAM) capabilities, and can realize flexible scheduling and management of large-capacity services, and has increasingly become the backbone transport network. The mainstream technology of the Internet. [0003] Ethernet needs to use the optical transport network to carry Ethernet signals for signal transmission, so as to realize the requirements of large-capacity and long-distance transmission of information. Based on the status quo of technology maturity and cost, the carrying capacity of OTN lines is limited. When the bandwidth of a single OTN line is not enough to carry Ethernet data traffi...

Problems solved by technology

[0008] After researching the existing technology, the inventor found that in the prior art, the dynamic line adjustment and the fault protection functions of some lines only take effect in the OTN, and cannot interact with Ethernet equipment. When the channel is unavailable, the Ethernet device cannot be notified in time to reduce the data flow, so that the multi-channel data cannot be combined to produce correct data, resulting in the failure of Ethernet data transmission

And when the Ethernet device adjusts the traffic, the OTN cannot make corresponding adjustments. For example, when the Ethernet data traffic decreases, the OTN still provides a large bandwidth, resulting in waste of resources.
