Abstract
The invention relates to the field of optical transmission, which discloses a method for reducing service switching time. The method only carries out register configuration to changed time slots in the process of modifying time slot configuration. The configuration operation is carried out only once to spur track time slots which belong to the same spur track unit group. Using the method of the invention can evidently improve the switching time and the effect is particularly evident in the situation that the spur track time slot configuration is relatively excessive. The operation of time slot configuration is improved.
Description
Technical field
The present invention relates to the optical transmission field, be specifically related to a kind of method that reduces business switching time.
Background technology
Along with the development of Science and Technology, modern society is increasing to the dependence of communication.The survivability of communication network has become crucial design to be considered, also becomes the important focus of the competition between market access environment lower network network operator or the service supplier.It is more and more serious that the consequence that communication disruption causes also becomes.Need not human intervention, the network that possesses protection/self-healing ability just can recover entrained business automatically from failure of removal in the extremely short time, make the imperceptible network of user occur fault.The basic principle of protection/self-healing is network to be possessed find to replace transmission route and establish the ability of communicating by letter again.The notion of protection/self-healing network only relates to and redefines communication, and no matter the recovery or the replacing of concrete actual effect component, the latter still needs manual intervention just can finish.
Usually, business recovery time and business recovery scope are two key criterias of tolerance network survivability, and different users has different requirements to the business recovery time with the recovery scope with different business.Service outage duration has two important threshold values.First is 50MS, can satisfy most professional quality requirements this moment.Second thresholding is 2S, and the 2S thresholding is called and connects drop-thresholds (CDT) as the desired value of network recovery.
So, when network breaks down, can realize switching services fast, be a requisite index for SDH equipment.
Summary of the invention
The present invention is in order to solve under the prerequisite of full dose time slot configuration, to dispose time slot and cause the problem that switching time is long.
The present invention is in order to reduce the time of configuration time slot cost, in the time of each time slot configuration, only a time slot that changes is configured processing.And, reduce the operation of repeatability, to reach the purpose of optimization process according to the characteristic of concrete business.
The method of minimizing business switching time of the present invention comprises the following steps:
The first step: open up and preserve the time slot configuration buffer memory, be used for preserving historical time slot configuration, and be initialized as not configuration status;
Second step: when the time slot configuration order arrives, travel through every time slot, its gap information is compared judgement,, changeed for the 3rd step if time slot changes; If time slot does not change, changeed for the 7th step;
The 3rd step: judge whether to be the tributary unit time slot, if the tributary unit time slot changeed for the 4th step; If not the tributary unit time slot, changeed for the 6th step;
The 4th step: judge whether tributary unit group register is configured, if not configuration changeed for the 5th step; If be configured, changeed for the 6th step;
The 5th step: configuration tributary unit group register;
The 6th step: configuration cross reference register;
The 7th step: judge whether time slot configuration travels through and finish, if the traversal end changeed for the 8th step; If traversal does not finish, changeed for second step.
The 8th step: current time slots is updated to historical time slot buffer area;
The 9th step: time slot configuration finishes.
Adopt the method for the invention, switching time can be improved significantly; Under the more situation of branch road time slot configuration, effect is particularly evident, has improved time slot operations.
Description of drawings
Fig. 1 is the process chart of the method for the invention;
Fig. 2 is the time slot configuration structural representation among the present invention.
Embodiment
As shown in Figure 2, comprised A, B, C, the operation of four modules of D in the cross time-slot configuration.
A wherein, B, the used time of the register manipulation of C has accounted for the major part of whole time slot configuration in total time.Channel time slot in the same tributary unit group is for A, B, and the register manipulation of C is identical.And same tributary unit group can issue 4 channel time slots at most, like this will be to A, and B, C, D have carried out identical operations 4 times, and the operating time exists bigger repeating to expend, and especially under the more situation of branch road time slot configuration, situation is more obvious.
In addition, when revising time slot configuration, owing to be the full dose configuration, so, also all will all reconfigure although time slot has just been done a spot of increase and deletion.
For this reason, the method for the minimizing business switching time that the present invention proposes is revised in the process of time slot configuration, just the time slot that changes is carried out register configuration; Belong to a channel time slot of same tributary unit group, only carry out configuration operation one time, improve the operation of time slot configuration.
A kind of method that reduces business switching time, concrete steps are as follows:
The first step: open up and preserve the time slot configuration buffer memory, be used for preserving historical time slot configuration, and be initialized as not configuration status;
Second step: when the time slot configuration order arrives, travel through every time slot, its gap information is compared judgement,, changeed for the 3rd step if time slot changes; If time slot does not change, changeed for the 7th step;
The 3rd step: judge whether to be the tributary unit time slot, if the tributary unit time slot changeed for the 4th step; If not the tributary unit time slot, changeed for the 6th step;
The 4th step: judge whether tributary unit group register is configured, if not configuration changeed for the 5th step; If be configured, changeed for the 6th step;
The 5th step: configuration tributary unit group register;
The 6th step: configuration cross reference register;
The 7th step: judge whether time slot configuration travels through and finish, if the traversal end changeed for the 8th step; If traversal does not finish, changeed for second step.
The 8th step: current time slots is updated to historical time slot buffer area;
The 9th step: time slot configuration finishes.
