Problems solved by technology

The process of delay alignment will cause interruption of services carried by the original members, packet loss, and the entire group needs to wait for several milliseconds (milliseconds) to work normally again.
[0005] In order to solve the problem of disconnection of the original member's bearing services caused by the dynamic increase of members in the flexible Ethernet, the present invention proposes a method based on ram to realize lossless addition and deletion of members in the FlexE group, and solves the problem of disconnection by caching data in ram. Implementing Dynamic Adjustment of FlexE Bandwidth

Embodiment 1

[0048] A method for implementing lossless addition and deletion of FlexE members based on ram, the specific implementation steps are as follows:

[0049]S1 adds members according to the actual FlexE group bandwidth requirements. The FlexE protocol defines the alignment block OH of the members in the group, and the OH code block is periodically inserted into the members;

[0050] The FlexE protocol defines the alignment block OH of the member, and the OH block is periodically inserted into the member (such as figure 2 shown), and its period is represented by period_L.

[0051] The fixed position of the OH code block is helpful for judging the loss of data blocks at the link layer.

[0052] When the S2 member arrives at the receiver, when the OH code block is detected, the data starts to be written into the ram;

[0053] There can be n members in the group group in FlexE (such as image 3 shown), when the member arrives at the receiver, when the OH block is detected, the dat...

Abstract

According to the method for realizing lossless addition and deletion of the members in the FlexE group based on the ram, the problem of flow interruption is solved through a mode of caching data by the ram, and dynamic adjustment of the FlexE bandwidth is realized.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method for implementing lossless addition and deletion of FlexE members based on ram. Background technique [0002] Flexible Ethernet (FlexE) can improve the transmission bandwidth of a single service port and is no longer affected by the bandwidth of the physical transport layer alone. Flexible Ethernet can also increase the number of service ports that can be carried in a single physical transport layer. Flexible Ethernet breaks through the one-to-one correspondence between service ports and physical transport layers in traditional Ethernet, and is widely used in large network processors and network switches. [0003] The flexible Ethernet protocol defines the concept of a group, which contains members, and the number of members is unlimited. The number of members determines the capacity of the bandwidth and number of service ports that can be accommodated. Controlli...
