The present invention also provides an ODUflex overhead retrieval method.

Referring to FIG. four; in FIG. 4 is a flowchart of a first embodiment of a method for extracting ODUflex overhead information in accordance with the present invention.

In a first embodiment of an ODUflex overhead retrieval method according to the present invention, the method includes the following steps.

Step S10: the frame synchronization module performs frame synchronization operations with respect to the ODUflex service and outputs ODUflex service data and frame header information corresponding to the ODUflex service.

The frame synchronization module receives the ODUflex service from the bus and performs the frame synchronization operation with respect to the ODUflex service, and the frame synchronization operation relates to obtaining information on frame headers and ODUflex service data in the ODUflex service, wherein the frame header information contains a frame header identifier, a header location frame, etc., and the ODUflex service data represents all the data in the ODUflex service. The frame synchronization module supports the characteristic that the number of time slots occupied by the ODUflex service on the bus, the location of the occupied time slots and speed are adjustable, that is, the condition is maintained that the time slots occupied by the ODUflex service on the bus are not continuous, and in addition, the number of time slots that can be occupied by the ODUflex service can be any number from 1 to the maximum number.

Step S20: each ODUflex service information retrieval unit and frame header information is received by each module, and retrieval of each part of the time interval data corresponding to the ODUflex service is retrieved in accordance with the obtained configuration information and frame header information.

Several service information extraction modules are provided, and each service information extraction module has different capabilities for extracting service information. For example, one service information retrieval module can retrieve only service information of one or several time slots, and different ODUflex services occupy different time slots, so several service information retrieval modules are required to retrieve service data of each part of the time interval data.

Each service information extraction module receives ODUflex service data and frame header information. For example, the frame synchronization module acquires the ability to extract service information of each service information extraction module and distributes ODUflex service data and frame header information between respective service information extraction modules in accordance with the service information retrieval capacity of each service information extraction module; or each overhead information extraction module sends a command containing its overhead information extraction ability to the frame synchronization module in accordance with the overhead information extraction module, and the frame synchronization module sends the corresponding ODUflex service data and frame header information to the overhead information extraction module after receiving the command.

Configuration information is generated and sent by the control module or other modules; the configuration information contains a time slot parameter of each ODUflex service in the bus, and the time slot parameter includes a time slot location parameter, a number of time slot parameter, and the like.

If the configuration information is regenerated or the configuration information is updated, it is required that the overhead extraction modules again receive the configuration information.

Since the configuration information contains a time slot parameter, overhead information extracting units may extract overhead data of each piece of time interval data in accordance with the obtained configuration information and frame header information.

For example, the full frame retrieval module sends the service information retrieval address to the corresponding service information retrieval modules in accordance with the configuration information that is received from the control module or other modules and stored, and the service information retrieval modules send service data about the time interval to the full module retrieving frames after receiving the address for retrieving service information; or the service information extraction modules automatically send the extracted service data of the time interval data to the module for fully retrieving frames after the service data is extracted.

The full frame retrieval module receives the service data of each piece of data about the time interval of the ODUflex service, thereby generating service data of the ODUflex service.

According to this embodiment, the service information extraction modules extract the service data of each part of the ODUflex service time interval data, then the full frame extraction module receives service data of each part of the time interval data to generate the ODUflex service data, and there is no need to separately install the extraction module service information for the occupation time interval of each ODUflex service; therefore, according to this embodiment, it is possible to reduce the number of overhead information extraction modules, significantly reduce costs, and also reduce the maintenance complexity of the overhead information extraction modules.

In an alternative embodiment of the present invention, before step S10, the method further includes generating configuration information by the control unit.

The configuration information is sent to the service information extraction modules and / or the full frame extraction module in accordance with a predetermined condition. For example, if the control module and the service information extraction modules and / or the full frame extraction module are activated, the control module sends configuration information to the service information extraction module and / or the full frame extraction module; overhead information extraction modules and / or a full frame extraction module receive / receive and save / save configuration information upon detection of configuration information; and if the configuration information does not change or is subsequently updated, it is not required that the control module resend the configuration information to the service information extraction modules and / or the full frame extraction module; or when activating the control module and the service information extraction modules and / or the full frame extraction module, the control module sends configuration information to the service information extraction modules and / or the full frame extraction module regularly or in real time; service information extraction modules and / or the full frame extraction module determines / determines whether the configuration information sent by the control module differs from the configuration information stored in the service information extraction modules and / or the full frame extraction module, and if so, accept / accepts configuration information; and, of course, the control module may further send configuration information to the service information extraction modules and / or the full frame extraction module by other modules, which is not limited in this document.

In a second embodiment of the method for extracting ODUflex overhead information according to the present invention, based on the first embodiment, step S10 in this embodiment includes the following frame synchronization module performs a frame synchronization operation with respect to the ODUflex service, outputs ODUflex service data corresponding to the ODUflex service to the modules retrieving service information and outputs information about the frame headers to the extraction selection module for sending by the header information extraction selection module x frames corresponding modules retrieve overhead information in accordance with the previously stored configuration information.

step S50: sending the ODUflex service overhead frame by the module to the service information processing module to process the ODUflex service service data processing module if the stored ODUflex service service data exceeds a predetermined storage amount.

For example, if the amount of stored ODUflex service overhead exceeds the preset storage volume, the full frame extraction module sends a request to the service information processing module, the service information processing module receives the request and returns the first service information extraction address to the full frame extraction module, and the full frame extraction module sends service data to the service information processing module in accordance with the service information extraction address.

Here, a predetermined storage amount can be set in accordance with a user requirement.
