Embodiment
Be described in detail as follows with regard to the preferred embodiments of the present invention below in conjunction with accompanying drawing:
Optical Fiber Interface Board is monitored the SNCP monitoring point, because after multiplex section rearrangement took place, the monitoring point can change.To simplify the process, the monitoring point is managed according to the multiplex section rearrangement page.Being that the page is equivalent to container, all is to get from receptacle when software needs the monitoring point.Organize according to the light mouth and the page monitoring point, behind the generation multiplex section rearrangement, because the monitoring point transfer, so the monitoring point of the different pages is different.Backward when service condition, during perhaps by bad improving, just report protection module to handle.This monitoring can carry out 1 in two ways: patrol and examine pattern; 2: interrupt mode.The processing speed of wherein patrolling and examining pattern is slower, do not reach SDH network switching time requirement (switching time of general SDH network requires＜=50ms), and relatively consume cpu resource.And interrupt mode has speed fast, to characteristics such as CPU usage are low.So using, great majority all adopt interrupt mode to monitor.We see Fig. 1 at existing handling process, and its detailed process is: at first, and the initialization main task.Then, professional when good, enable to interrupt; When business degenerated, at this moment hardware reported interruption, and notice software, software just at once shielding interrupt, because business when degenerating, shake occurs probably, that is, business is not the very stable bad state that is in, and bad during fashion.If do not shield interruption, just may cause the software interrupt service routine frequently to be called, and then cause the software reset; Report the protection module on upper strata then.And the task of patrolling and examining exactly the business of monitoring improve, it is still good to wait after continuing for some time, and just enables to interrupt, and reports the protection module on upper strata.Because professional do not had to be strict with to the time by bad improving, can be competent at so patrol and examine.
Fig. 2 is the two-fibre two-way multi-section rotating loop of one 4 website, considers to go up to network element C business from network element A.The convenience of be discussing establishes that professional the left side light mouth of establishing the C network element is an east orientation on 1 passage, and it is western to receipts that be the west be to, main business that east orientation is sent out on the right.If on network element C, this business has been carried out SNCP monitoring (at this moment its pairing light mouth passage is exactly a SNCP monitoring point), so its SNCP monitoring point just in the west on 1 passage.At this moment, disconnected fibre takes place between network element B, C, multiplex section protection just begins to work.By the multiplex section agreement, we know that this business forwards to from A-＞B-＞A-＞D-＞C.Concerning network element C, the business of just can not on 1 passage, monitoring in the west, monitor and should arrive on east orientation 1 passage.In the multiplex section agreement, mainly contain three kinds of states: normal state, break-through attitude, switch attitude.And multiplex section is divided into agreements such as two fine unidirectional, two-fibre two-ways, four-fiber bidirectional.The original residing multiplex section direction in monitoring point difference, perhaps agreement difference, perhaps state difference, the transfer case of monitoring point is also inequality so.
The present invention is with in the various multiplex section rearrangement states, the monitoring point situation is listed as into a two-dimensional matrix structure, the subscript of matrix is respectively: passage is present position, multiplex section rearrangement state in multiplex section, can obtain to shift the residing page in monitoring point, back by these two parameters then, and which monitoring point is shielded.According to page number, software can be known for which monitoring point, and shields which monitoring point.The page divides homepage, the ring page and the span switching page, and passage divides the work passage, the passage in protection passage and the non-multiplex section.
Like this in the transfer processing process of whole monitoring point, wholwe-hearted the enabling, shield of handling interrupt, and to where specifically transferring to, then in matrix structure, realize.Improved the readable and maintainable of software.
Be that example in conjunction with the two-fibre two-way multi-section ring describes below, see accompanying drawing 3 for details:
Two wiring board A, B.A light mouth is arranged respectively, and speed is 2.5G, promptly is divided into 16 VC4 passages (later passage all refers to the VC4 passage).The user disposes multiplex section protection, makes the 1-4 passage of A plate 1 light mouth be in the position, east 1 (E1) of multiplex section, and B plate 1 light mouth 1-4 passage is in the position, west 1 (W1) of multiplex section.The user disposes SNCP protection then, makes the 1st, 5 passage on the A plate 1 light mouth, and the 1st, 5 passages respectively have a SNCP monitoring point on the B plate 1 light mouth, and relevant configuration is stored in the homepage.
When the wiring board software startup, the upper strata host software has issued the configuration of SNCP monitoring point earlier and has given wiring board software, comprises the monitoring point of homepage, the ring page, the span switching page.Wherein homepage is exactly the monitoring point information that is directly issued by the user: 1,5 passages of 1 light mouth of A, B plate respectively have a SNCP monitoring point, totally 4 monitoring points.And the ring page and the span switching page will be done a calculation process, and the monitoring point of the passage on the ring page and the span switching page in service aisle and the non-multiplex section is that this monitoring point, position by board software copy homepage forms; Monitoring point on the protection passage is issued the monitoring point on the corresponding service aisle on the plate homepage by the main frame basis.With the ring page is example, and the monitoring point on the service aisle should be in the monitoring point of this position and corresponding protective position copy homepage; In this example, 1 passage on A, the B plate all belongs to the service aisle on the multiplex section, so should be a at this position copy, and should correspondence protect on the passage copy a (for A plate 1 light mouth 1 passage, be exactly on B plate 1 light mouth 9 passages copy a with the same monitoring point of A plate 1 light mouth, 1 passage; To the B plate in like manner).Like this, on the ring page, A plate 1 light mouth 1 passage, 9 passages are just arranged, B plate 1 light mouth 1 passage, 4 monitoring points of 9 passages.
Below this matrix be after multiplex section rearrangement takes place, the operation that wiring board is done:
So that multiplex section east to take place is example, analysis according to Fig. 2, should arrive the monitoring point is 4: 5 passages of A, B plate 1 light mouth are not in multiplex section, so still exist, the monitoring point of A plate light mouth 1 passage is because professional the transfer, be transferred on B plate 1 light mouth 9 passages, and B plate 1 light mouth 1 passage still keeps.
According to this matrix table, investigate the monitoring point on the B plate 1 light mouth because B plate 1 light mouth be the west to, fall in multiplex section east, so should be to enter the ring page, the B plate 1 light mouth on the ring page has two monitoring points: 1 passage and 9 passages.Investigate the monitoring point on the A plate 1 light mouth, because A plate 1 light mouth is an east orientation, so should be to enter homepage, homepage be that two monitoring points of 1,5 passages are arranged, and shields eastern 1 monitoring point (i.e. 1 passage) then, so only remaining 1 monitoring point of plate 5 passages.We as can be seen, the calculating by matrix is consistent with the analysis of beginning.
In sum, the present invention describes the preferred embodiments of the present invention in conjunction with the accompanying drawings in detail, however description of the invention, describe in detail and above-mentioned accompanying drawing be not be used for limiting of the present invention.To those skilled in the art, can carry out various corresponding modification and can not exceed the spirit and scope of the present invention under instruction of the present invention, therefore this variation should be included within claim of the present invention and the equivalent scope thereof.
