Problems solved by technology

[0003] When customer business data is loaded on the FLEXE shim layer for carrying, it is necessary to insert idle information blocks for rate adaptation to meet the speed requirements of the FLEXE shim layer, so that some idle information blocks are carried on the FLEXE, resulting in waste
Since the customer service flow selects a fixed number of time slots on FLEXE, it is a rigid pipeline. When the customer traffic becomes smaller, because the customer exclusively occupies the time slots on the FLEXE shim sublayer, in order to adapt to the speed, idle information blocks will be inserted, resulting in transmission Channel utilization is low, resulting in waste

Embodiment 1

[0095] Embodiment 1. A method for delivering business flows in the FLEXE protocol, such as Figure 8 shown, including:

[0096] S110. The sending end encapsulates the predetermined customer service flow;

[0097] S120. The sending end inserts the encapsulated predetermined client service flow into a predetermined type of control information block in a FLEXE service time slot and sends it.

[0098] In this embodiment, the control information block is used to carry additional service flows, which improves the carrying efficiency of the FLEXE shim layer and generates additional economic value.

[0099] In this embodiment, the control information block may refer to an information block whose attribute indication bit content is 10; the type of the control information block may be determined by the content of the first byte of the control information block.

[0100] In this embodiment, there may be one or more predetermined customer service flows. When there are multiple predeter...

Embodiment 2

[0131] Embodiment 2, a method for transferring business flows in the FLEXE protocol, such as Figure 9 shown, including:

[0132] S210. The receiving end extracts the information content in the predetermined type of control information block in the FLEXE service time slot;

[0133] S220. The receiving end acquires the predetermined customer service flow according to the extracted information content.

[0134] In this embodiment, the control information block is used to carry additional service flows, which improves the carrying efficiency of the FLEXE shim layer and generates additional economic value.

[0135] In this embodiment, the control information block may refer to an information block whose attribute indication bit content is 10; the type of the control information block may be determined by the content of the first byte of the control information block.

[0136] In this embodiment, obtaining the predetermined customer service flow according to the extracted informa...

Embodiment 3

[0180] Embodiment 3, a device for transferring business flows in a flexible Ethernet FLEXE protocol, such as Figure 15 shown, including:

[0181] An encapsulation module 31, configured to encapsulate predetermined customer service flows;

[0182] The transfer module 32 is configured to insert the encapsulated predetermined customer service flow into a predetermined type of control information block in the FLEXE service time slot and send it.

[0183] In an implementation manner, the predetermined type of control information block may be, but not limited to, an idle information block.

[0184] In an implementation manner, the predetermined customer service flow may be, but not limited to, the customer service flow with the lowest priority.

[0185]In an implementation manner, the transfer module inserts the encapsulated predetermined customer service flow into a predetermined type of control information block in the FLEXE service time slot and sends it may include:

[0186]...

Abstract

The invention provides a method, device and system for transmitting service flow in a flexible Ethernet protocol. The method for transmitting the service flow in the flexible Ethernet (FLEXE) protocolcomprises the following steps: a sending end carries out package on a preset customer service flow; and the sending end inserts the packaged preset customer service flow into a preset type of controlinformation block in a FLEXE service time slot for sending. The method, device and system can improve utilization rate of a transmission channel, thereby improving service transmission efficiency.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method, device and system for transferring service flow in a flexible Ethernet protocol. Background technique [0002] The rapid increase of user network information flow has promoted the rapid development of communication network information transmission bandwidth. The interface bandwidth speed of communication equipment has increased from 10M (unit: bit / second, the same as the following) to 100M, and increased by 1G and 10G. To achieve the bandwidth speed of 100G, a large number of 100G optical modules have been commercially used in the market. 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. In order to deliver 400G services on 100G optical modules, the International Standards Organization has defi...
