Problems solved by technology

[0006] 1. The 100G physical channel only defines 20 time slots, and the total number of time slots is too small; 2. The bandwidth of each time slot is 5G, resulting in too large granularity of a single time slot; and in the field of PTN business, customer business The number is large, and the bandwidth of each service is relatively small, that is, the number of slots is large, and the bandwidth granularity of a single time slot is small, which makes the current FLEXE protocol unable to meet the application scenarios of PTN services

Embodiment 1

[0082] see Figure 6 , which shows a service bearer method provided by an embodiment of the present invention. In this embodiment, figure 1 The shown FLEXE network structure is taken as an example for illustration. The FLEXE network structure includes a service sending end and a receiving end. The method includes:

[0083] S601: The sending end determines the position of the bearer time slot used to bear the service to be transmitted;

[0084] S602: The sending end determines the position of the bearer data block group used to bear the service to be transmitted;

[0085] S603: The sending end transmits the service to be transmitted according to the position of the bearer time slot and the position of the bearer data block group;

[0086] S604: The receiving end determines the location of the received data block group used to carry the service to be received;

[0087] S605: The receiving end determines the position of the receiving time slot for carrying the service to be re...

Embodiment 2

[0108] Based on the same technical concept as the foregoing embodiments, this embodiment describes the technical solutions of the foregoing embodiments through specific examples.

[0109] For example, there are three services, namely service A, service B and service C; among them, the bandwidth of service A data is 2.5G, the bandwidth of service B data is 7.5G, and the bandwidth of service C is 1.25G.

[0110] Therefore, for the service data of service A, the configurations performed by the sender are time slot number {1}, data block group number {1, 3, 5 and other odd numbers}; that is, the sender carries the data of service A Send at the No. 1 time slot position in the block group whose data block group number is odd, and correspondingly, the receiving end will also receive the data block at the No. 1 time slot position in the block group whose data block group number is odd;

[0111] For the service data of service B, the sending end includes two groups of location configur...

Embodiment 3

[0119] Based on the same technical idea of ​​the foregoing embodiments, see Figure 8 , which shows a service bearer method provided by an embodiment of the present invention, this method can be applied to figure 1 For the sending end in the shown FLEXE network structure, the method may include:

[0120] S801: The sending end determines the position of the bearer time slot used to bear the service to be transmitted;

[0121] S802: The sending end determines the position of the bearer data block group used to bear the service to be transmitted;

[0122] S803: The sending end transmits the service to be transmitted according to the position of the bearer time slot and the position of the bearer data block group.

[0123] Exemplarily, before step S801, the method further includes:

[0124] The sender numbers the time slots in the Calendar of the FLEXE protocol, and numbers the data block groups within the coverage of the overhead block.

[0125] Specifically, the sender can n...

Abstract

The embodiment of the invention discloses a method, equipment and system for bearing service. The method comprises the following steps: a sending end determines a bearer time slot location for bearingto-be-transmitted service; the sending end determines a bearer data block group location for bearing the to-be-transmitted service; and the sending end transmits the to-be-transmitted service according to the bearer time slot location and the bearer data block group location.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a method, device and system for bearing services. Background technique [0002] The rapid development of network technology and the rapid increase of network information flow have prompted the corresponding rapid development of the transmission bandwidth of the communication network. The interface bandwidth speed of communication equipment has increased from 10M (unit: bit / s) to 100M, and then increased to 1G and 10G. At present, the interface bandwidth speed of 100G has been reached, and a large number of 100G optical modules have been commercially used in the market. [0003] At present, 400G optical modules have been developed, but the price of 400G optical modules is expensive, exceeding the price of four 100G optical modules, resulting in the lack of commercial economic value of 400G optical modules. Therefore, in order to transmit 400G services on 100G optical mo...
