Embodiment

Below with reference to Fig. 2 to Fig. 4 embodiments of the invention are made a detailed description.

At first software reset's processing before being appearred in main frame describes.When main frame powered on and move business, needs were carried out business configuration earlier and are backed up connecting configuration information.The process flow diagram that Fig. 3 shows business configuration and connects the configuration information backup.As shown in Figure 3, the raw information that connects configuration is imported by user interface, after the business configuration resume module, generate cross matrix and be issued to Physical board, promptly write the professional register that connects of control, business can correctly be connected, finish outside visible business configuration flow process, that is, by observing visible professional true(-)running.Connection configuration information after generate handling is saved in the backup database, so that use when generating cross matrix by the business configuration module behind network element reset.In addition, the business configuration module is also noted the operating position of physical channel when generating cross matrix, generate a connection resource in view of the above and use information, this connection resource uses information to have corresponding relation accurately with the above-mentioned configuration information that is connected, because the resource that may exist such as the dynamic adjustment of interleaving route, causing this lost route after resetting, thus need preserve this resource use information, so that can recover.The teleservice that connects configuration information reflection user static configuration connects, and connection resource uses the route of a professional end to end institute of message reflection warp.The connection resource that generates uses information also can be kept at separately in the middle of the pen recorder (example is the FPGA of crucial veneer as will be described) in the middle of above-mentioned connection configuration information is saved described backup database.And, use information to be saved with above-mentioned connection configuration information under the situation in the described backup database at the connection resource that generates, both connection resource use information can be integrated with described connection configuration information, also can be with its independent preservation.

Fig. 2 is the FB(flow block) according to the described software reset's control method of the embodiment of the invention.As shown in Figure 2, when host software resets, business configuration module (see figure 3) utilizes the connection configuration information of preserving in the described backup database to generate cross matrix, and the resource use information of preserving in according to backup database or pen recorder when generating cross matrix is distributed the physical channel.The business configuration module is to finish said process by calculating, and concrete computing method can adopt the mode of chained list to preserve interleaving route, and the cross connection information table is shown as matrix form, and the physics of this matrix representation cross chips goes out the inbound port annexation.High and low rank matrix shows as two port tables of coming in and going out, and going out inbound port can not have conflict.The aforementioned calculation method all is known to those skilled in the art, therefore repeats no more.Because user configured connection configuration information and routing iinformation can be determined unique cross matrix, thus the cross matrix that generates when resetting can with reset before in full accord.

In addition; after the aforementioned calculation process is finished; because all being protection, all link informations of calculating switch preceding original state; if overprotection takes place before host software resets switches; if directly the link information of calculating is issued to veneer; wait for then after veneer reports and select standby connection again, then might cause professional hit because the switching of connection is arranged in the centre.Therefore, the present invention also protects the situation of switching to take further step to occurring.Fig. 4 is a synoptic diagram of preserving switch status.As shown in Figure 4; when business generation protection is switched; protection is switched processing module and will be saved in selected connection (switch status information) in real time in the middle of the device that can write down switch status information of a crucial veneer (as cross board); this device can adopt FPGA (field programmable gate array); also can adopt database etc., that adopt in an embodiment of the present invention is FPGA.Because described crucial veneer is bad or power down occurs, then business will be damaged, and does not have the non-volatile characteristic of power down so this type of save set requires, as for the backup protection of crucial veneer then not within the discussion scope of this paper.When host software reset appear at the protection switch after the time; the business configuration module can be in the process of above-mentioned generation cross matrix; read the switch status information of preserving in the described pen recorder with choose reset before the selected connection of protection turning protocol module; even taking place to reset the back non-interrupting service of also can accomplishing to reset under the situation that service protection switches like this.

Though should be noted that explanation of the present invention is carried out according to its specific embodiment, it does not also mean that limitation of the present invention.To those skilled in the art, under the situation that does not break away from the spirit and scope of the present invention, can make various modifications and conversion to it.For example, though the device of the preservation switch status information of Cai Yonging is FPGA in the crucial veneer in the present invention, also can adopt other memory storage or database.In addition, described connection resource uses information not only can be kept in the backup database with connecting configuration information, also can be kept at separately among the FPGA of crucial veneer or in other memory storages.In a word, do not deviate from the various remodeling of spirit of the present invention all within the protection domain of the appended claim of the present invention.
