Problems solved by technology

The traditional 1+1 cross-disk active / standby protection method requires a large number of protection slots, which will lead to increased equipment expenses and higher enterprise costs
Assuming that a system needs 4 active cross disks, then 4 backup cross disks are needed to complete the protection, which will lead to a large number of cross disks and a significant increase in system cost

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] Taking the optical transmission equipment as an example, the protection mode of the cross-disk M ratio N described in the present invention is as follows: figure 1 As shown, it shows the composition of functional modules supporting the present invention and the flow relationship of main signals, mainly including the following module units:

[0032] The link detection and capacity allocation units A and B are used to realize the link detection and capacity allocation functions of the service disk, and the link detection and capacity allocation units A and B are connected through several cross disks, figure 1 In the shown embodiment, five cross disks C1-C5 are connected,

[0033] The link detection and capacity allocation unit is used to complete the detection of whether the link is available, and then carry out the equal distribution of the service cap...

Abstract

The present invention relates to a protection mode of cross disc M to N. A link detection and capacity allocation unit A and a link detection and capacity allocation unit B are connected through a plurality of cross discs, according to a result of link detection, data service capacity is allocated on an available link, sending data service is started, after data is sent to each cross disc, the cross disc finds a corresponding physical link and finally forwards the data service to the link detection and capacity allocation unit B according to chip target MAC in the data service. According to the protection mode of the cross disc M to N, equal distribution of data of a service disc can be realized, seamless switching of the cross disc can be realized on this basis, a service flow of a cross disc protection mode is optimized to the max, a number of slots needed by the cross disc can be reduced, and cost pressure of too many cross discs and a technical bottleneck of sending simultaneously and receiving selectively are solved effectively.

Description

technical field [0001] The invention relates to the protection of optical transmission products in the field of communication, in particular to a protection method for the M ratio of the cross-disk. That is: a disk redundancy protection method for an M-to-N (M:N) cross disk. Both M and N are positive integers greater than or equal to 1. Background technique [0002] In optical transmission products, the cross-connect disk is a core unit. Once the cross-connect disk fails, the service of the entire system will be interrupted. In traditional optical transmission equipment, the protection mode of the cross-connect disk is usually a 1+1 mode in which the active and standby cross-connect disks protect each other. The characteristics of this method are: [0003] First, the working status of the two can be clearly distinguished. Normally, only one of them is actually in the working state (main cross-disk) and the other is in the protection state (standby cross-disk) during normal...
