Description

Branch board time slot configuration method and device

Technical field

The present invention relates to a time slot configuration processing method and apparatus for a tributary board in a Synchronous Digital Hierarchy (SDH) optical transmission device.

Background technique

Optical synchronous digital transmission networks have been widely developed and applied in the field of optical communication. With the increasing social life and the advancement of technology, the demand in the field of optical communication is becoming more and more diversified. The optical network can flexibly and quickly realize the adjustment of business, and will better meet the various needs of different customers. This puts more stringent requirements on SDH equipment or network elements in terms of time slot cross configuration.

In an optical synchronous digital transmission network, if data transmission exists between two network elements or within a single network element, time slot configuration must be performed. The function of the time slot configuration is to determine the specific cross path during transmission for all given time slots and incoming time slots. After the slot relationship is configured on the NMS, the NCP (Net Control Processor) sends a time slot crossover command to the slot algorithm module. After the algorithm is processed, specific path configuration commands are obtained. result. The NCP then sends the result of the configuration command to each board in the NE. The board implements the cross-configuration of the service, that is, the path between the in-time slot and the e-slot. The purpose of the time slot algorithm is to: arrange the communication path of the time slot flow in the hardware resources (the air separation module, the time division module, and the tributary module) according to the inbound time slot and the outgoing time slot delivered by the network management, that is, complete the time slot. Configure the calculation of the function.

The position of the outgoing time slot and the incoming time slot may be between the light plates or the light plate to the tributary board. A certain time slot may only need to complete the intersection of the outgoing and the indirect through the space division cross matrix, and may also need to complete the intersection of the outgoing and the incoming through the space division cross matrix and the time division cross matrix. The current level of hardware technology determines that for the AU (Administrative Unit) level (transport rate level), the time slot signal can be implemented by the AU-level space division cross matrix, and the time slot signal below the AU level cannot follow. The AU where it resides uses the space division cross to complete the intersection of this level, and they can only rely on the cooperation of the air separation module and the time division module to complete the intersection. Of course, for some technical requirements, it may also be stipulated that the AU-level time slot signal must be configured once through the space division cross-matrix. For the time-slot signal below the AU level, the space division module and the time division mode must pass. The mating of the blocks is done to complete the intersection. In order to realize the signal transmission between the signal boards below the AU level, the time division module internally realizes the time slot crossing below the AU level, and the connection between the time division module and the signal board passes the AUG bus between the AU level space division cross matrix and the signal board. Perform AU level signal slot exchange.

For the tributary board, if all the AUs are vacated and distributed to the tributary board, the position of the lower service signal under the tributary board bus has been determined, otherwise all the TU (Tributary Unit) signals of the AU are supported. The location of the bus under the board has not been determined. For all cases where the AU is taken to the branch circuit, the undetermined TU signal of the AU is arranged at the specific position of the tributary bus.

If there is no set of processing mechanism for a good tributary board service, there may be low operational efficiency when the tributary board is configured in time slots. Or, for the same time slot data, there is a situation where the tributary board resources remain, but the configuration cannot be completed.

The traditional tributary board processing module does not use the same method for the specific attributes of the branch board, which is time-consuming and cannot fully utilize the existing resources of the tributary board. Summary of the invention

The main idea of the tributary board time slot configuration method and device is to determine the time slot configuration mode according to the total number of tributary ports of the tributary board. When the total number of tributary ports is less than or equal to the preset threshold, the fixed connection configuration mode is adopted. Otherwise, use the plug-in configuration method to achieve full utilization of the tributary board resources.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. Example 1

As shown in FIG. 1, the embodiment 1 of the tributary board time slot configuration method of the present invention includes:

Step 101: The SDH device determines the time slot configuration mode according to the total number of the branch ports of the tributary board. If the total number of the branch ports is less than or equal to the preset threshold, it is determined to be a fixed connection configuration mode; otherwise, it is determined to be an empty configuration mode;

The preset threshold may be determined according to the capacity of an Administrative Unit Group (AUG). For example, the threshold is the maximum number of the branch board support services accommodated by the two management unit groups (AUGs). Preferably, the tributary boards can also be classified as follows:

A type of tributary board: the total number of tributaries of the tributary board is lower than or equal to the maximum number of supporting services of the tributary board that an AUG can accommodate;

The tributary board of the second type: the total number of the branch ports of the tributary board is greater than the maximum number of supporting services of the tributary board that can be accommodated by the AUG, and is less than or equal to the maximum number of supporting services of the tributary board that the two AUGs can accommodate;

Three types of tributary boards: The total number of tributaries of the tributary board is greater than the maximum number of tributaries supported by the two AUGs.

The maximum number of support services that the AUG can accommodate is that an AUG can contain up to three VC3s, or 63 VC12s, or 84 VC11s. The VC3 type tributary board supports the largest VC3 service. The number is three, and so on.

Preferably, the above-mentioned one-type and two-type tributary boards are fixedly connected, and the three types of tributary boards are in an empty configuration.
