Description
Technical field
The present invention relates to optical communication field, when being specifically a kind of network management upgrading, save the method for line card internal memory.
Background technology
Along with the fast development of the communication technology, the weeding out the old and bring forth the new of communication facilities, business constantly expands, function constantly increases, and causes the binary file size of voice terminal device increasing, also continues to increase line card request memory during network management upgrading communication facilities.
At present, during light mouth network management upgrading software, the binary file of voice terminal device is first from NM server FTP (File Transfer Protocol, file transfer protocol (FTP)) on main control unit, treat that main control unit receives, main control unit by the whole binary file FTP that receives to line card, after line card receives, line card by binary file TFTP (Trivial File Transfer Protocol, TFTP) on voice terminal device.Because the userbase of Access Network constantly expands, operation, the maintenance and management workload of network also progressively rise, and also get more and more to the summation function that needs of voice terminal device.But the memory size of line card limits the binary file size of voice terminal device, and the time requirement of FTP and TFTP is very high, if batch upgrade voice terminal device, need to complete sequence of operations within the time of FTP and TFTP requirement, could successfully return, otherwise can as timeout treatment.In order to add function perfect as far as possible, the binary file of the voice terminal device therefore issued can be increasing, but also more and more higher to the rate request of webmaster batch upgrade.
Solved the problem following two methods at present:
1. strengthen line card internal memory, the internal memory of the voice terminal device that is used for by line card upgrading strengthens, and directly deals with problems.But this method cannot save internal memory, simultaneously because the size of binary file is increasing, line card internal memory along with the change of scale-of-two upgrade file large and increase, the network management upgrading time can be more and more longer, thus cannot improve the updating speed of webmaster.
2. progressively degree-raising approach, upgrades large binary file divided data, does not need to wait for that whole file transfer is complete.That is, a part of data from NM server FTP to main control unit, direct FTP is to line card, and line card again TFTP, to voice terminal device, returns to NM server after success again, by that analogy, until the upgrading of whole binary file is complete.But this process, larger for batch upgrade elapsed time, likely cause FPT or TFTP time-out, and each equipment of centre all can not power-off, once power-off, the binary file data before transmitted, because sufficiently complete, needs to roll back on original version, requires higher to stabilization of equipment performance.
Summary of the invention
For the defect existed in prior art, the object of the present invention is to provide a kind of method of saving line card internal memory during network management upgrading, save line card internal memory, improve the updating speed of webmaster, do not adopt and progressively upgrade, lower, easy to use to the requirement of stabilization of equipment performance and whether power-off.

On the basis of technique scheme, described upper level applications and DSP upper layer drivers merge, as the scale-of-two upgrade file that voice terminal device is new.
On the basis of technique scheme, described remote upgrade upper level applications and DSP upper layer drivers, then upgrade the binary file program of optical network unit, if be updated successfully, namely restart whole optical network unit, comprise and restart dsp chip; If upgrade unsuccessful, then the software version before the software version of optical network unit being rolled back to upgrading.
On the basis of technique scheme, described remote upgrade DSP edition data, when upgrading the DSP edition data of optical network unit, first read front 4 bytes of the DSP edition data of renewal, if front 4 bytes are newer than front 4 byte version numbers of the DSP edition data stored in optical network unit, then upgrade described DSP edition data.
On the basis of technique scheme, if upgrade the success of described DSP version, then restart dsp chip separately; If unsuccessful, then the DSP edition data of optical network unit inside is rolled back to original version.
On the basis of technique scheme, described in restart dsp chip after, then restart DSP upper layer drivers.
On the basis of technique scheme, described in restart dsp chip and will judge whether to read DSP edition data, if not, according to original flow startup dsp chip; If so, then read front 4 bytes of DSP edition data, if not up-to-date version number, then upgrade described DSP version.
On the basis of technique scheme, read the 2nd 4 byte content, the i.e. data length of DSP version of described DSP edition data, distribute the DSP edition data of space storage from described reading of equal length, then DSP edition data is sent to dsp chip.
Beneficial effect of the present invention is:
1. DSP edition data is separated, put into specific FLASH region, be equivalent to the scale-of-two upgrade file just reducing voice terminal device, line card internal memory need not continue to increase along with the increase of binary file, also the restriction of binary file size network management upgrading would not be become, thus when webmaster batch upgrade voice terminal device, save line card memory headroom.
2. DSP driver is divided into DSP upper layer drivers and DSP edition data (i.e. DSP Firmware), the DSP edition data that the manufacturer of dsp chip provides generally can be very large, and generally can not manufacturer's version of frequent updating dsp chip during remote upgrade program, whether therefore the present invention is separable programming, does not adopt and progressively upgrades, stablize each equipment during upgrading, the requirement of power-off is lower, hardware requirement is low, and realizes simple, solves the too high problem of stability requirement.
