Problems solved by technology

[0005] However, the inventors found that in the process of realizing the above-mentioned technical solution, there are the following defects: when the first method is adopted, since the bandwidth of the ODU2 does not match the 10GE LAN, it is necessary to use 11 ODU2 channels to adapt to the 100GE service, which makes the bandwidth utilization When the second method is adopted, the bandwidth of one ODU3 is about 40G, while the bandwidth of 100GE is 103.125G, which makes the bandwidth of two ODU3s insufficient, and the bandwidth of three ODU3s causes nearly 20% bandwidth waste
[0006] In summary, the bandwidth utilization in the prior art is low

Embodiment Construction

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0055] In order to make those skilled in the art more easily understand the technical scheme of the present invention, the following figure 2 A schematic diagram of a service mapping path based on an optical transport network is shown for description. Map the service (the service shown in the figure is 100GE) to 10 second-level enhanced optical channel data unit virtual concatenation transmission containers (ODU2e-10v), and then split ODU2e-10v into 10 second-leve...

Abstract

The invention relates to a method and a device for transmitting business. The method comprises the following steps of: mapping business to be transmitted to a preset virtual concatenation transmission container; splitting the virtual concatenation transmission container; selecting the wavelength grade for transmitting the business; mapping the split transmission container into a transmission container corresponding to the wavelength grade; and transmitting the business to the transmission container corresponding to the wavelength grade. The use ratio of bandwidth can be improved and the hardware cost is reduced by the embodiment of the invention.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for transmitting services. Background technique [0002] OTN (Optical transport network, optical transport network), as the core technology of the next generation transmission network, has rich OAM (Operation, Administration and Maintenance, operation, management and maintenance) and powerful TCM (Tandem connection monitor, tandem connection monitoring) capabilities and out-of-band FEC (Forward Error Correction, Forward Error Correction) capability, so that flexible scheduling and management of large-capacity services can be realized, and it has increasingly become the mainstream technology of the backbone transmission network. [0003] The current OTN (Optical transport network, optical transmission network) standard mainly uses SDH (Synchronous Digital Hierarchy, synchronous digital series) as the main customer signal, which is reflected in the...
