Realization of the present invention mainly depends on interface chip and switches the control logic chip, introduces this two aspects below in detail:
What data abandoned when 1, interface chip adopted the dual transmitting and receiving mode to realize switching is minimum
Master control borad and business board adopt equally or can realize the interface chip of said function; when master control borad need be with a plurality of business board simultaneously; can adopt the chip of the integrated a plurality of 1+1 protection links of monolithic; but basic principle all is the same, is the operation principle that example illustrates interface chip with the chip that has only a 1+1 protection link below.
As shown in Figure 3, interface chip mainly is made up of three big modules: data link is selected module, string and modular converter, cpu i/f module.Be respectively described below:
String and modular converter are finished the conversion that service bus arrives the backplane interface high speed serialization link in the plate, and each interface chip is supported at least one pair of high-speed link, and promptly at least one pair of is gone here and there and modular converter, and one main one is equipped with, support 1+1 protection function; String and modular converter are supported the transmission of management data and business datum simultaneously;
The cpu i/f module provides the function of communicating by letter with CPU.
Data link selects module to select for the business datum of receive direction.For management data, active and standby two links all can be handled, and do not abandon; For business datum, two high-speed links of sending direction send simultaneously, but data link selects module only to select the business datum of active link to transmit to Service Processing Module according to the link switchover signal when receiving, and the reserve link data directly abandon.
The key function of interface chip is main/slave link implementation dual transmitting and receiving function, management data has different signs with business datum, be designated differentiation with this both are carried out different processing, management data is is all received and dispatched with link simultaneously regardless of active and standby, but business datum is carried out dual transmitting and receiving according to the link switchover signal.
2, it is all very fast that switchover mode flexible and selectable and every kind of mode are switched speed
Switch the control logic chip as shown in Figure 4 on the master control borad, this logic chip mainly is made up of three big modules: link selection module, masterslave switchover module, cpu i/f module, wherein:
The masterslave switchover module receives the active and standby signal of using to plate, and send this plate active and standby with signal to plate and business board, finish the masterslave switchover function according to the state information of this plate with to the active and standby of plate with situation;
The cpu i/f module only provides a function of communicating by letter with CPU, will be to the active and standby information of using of plate, and active and standby usefulness/alarm signal that each business board is brought reports CPU, and the number order of simultaneously CPU being assigned is carried out, such as initiating masterslave switchover, link switchover etc.;
The link selection module is mainly finished the link switchover function, comprises following two kinds of situations:
1) finishes data link masterslave switchover function when business board self, be that business board itself is when having the masterslave switchover function, business board is given the active and standby of master control borad and is used as the active and standby index signal of using with indication/alarm signal, the link selection module of master control board switching control logic chip is active and standbyly carried out link selection with index signal according to what business board was brought, the output link switching signal is finished the link switchover of this plate corresponding interface chip, and link switchover is gone on working traffic plate link corresponding.This realizes only relating to simple a switching of hardware signal transmission and logic chip, and speed can be controlled at the 10ns rank, and is very fast;
2) do not realize the masterslave switchover function when business board self, be that business board itself does not have the masterslave switchover function, and just according to master control borad bring active and standby when selecting the active link of oneself with index signal, business board is given the active and standby of master control borad and is used as alarm signal with indication/alarm signal, low level represents that business board is working properly, and high level is represented the business board operation irregularity; When the link selection module of master control board switching control logic chip detects the business board state by normally becoming when unusual, just this situation is reported CPU with interrupt mode by the cpu i/f module, CPU can alarm on the one hand, can whether be in main operating state according to this moment master control borad interface chip and the high-speed link that connected of this piece business board on the other hand and judge whether needs initiation link switchover with state and active and standby each other another piece business board, initiate link switchover as needs, then finish the link switchover of this plate corresponding interface chip by link selection module output link switching signal.Finish with logic chip owing to detect, CPU handles with interrupt mode, so this time of switching is also very fast, the time of us level can finish.
Like this, during the master control borad fault, carry out masterslave switchover according to the state information of this plate with to the active and standby of plate with situation, and simultaneously the active and standby of master control borad sent to business board with signal, by the switching of switching control logic chip controls business board active link of business board.
Simultaneously, when the business board fault, the link selection module of master control board switching control logic chip is active and standbyly carried out link selection with index signal according to what business board was brought, and the output link switching signal is carried out link switchover; Or active and standbyly report CPU with alarm signal according to what business board was brought, by CPU control carrying out link switchover.
As shown in Figure 5 and Figure 6, on the business board switch on control logic chip and the master control borad to switch the control logic chip similar, what this logic chip on the business board was same mainly is made up of three big modules: link selection module, masterslave switchover module or alarm module, cpu i/f module.
The cpu i/f module only provides a function of communicating by letter with CPU, will be to the active and standby information of using of plate, active and standby usefulness/alarm signal that each business board is brought reports CPU, and the number order of simultaneously CPU being assigned is carried out, such as initiating masterslave switchover, link switchover, alarm etc.;
The link selection module is relatively simple, only need select to get final product according to the active and standby active link of finishing this plate with index signal of master control borad, and such as left side master control borad master usefulness, just the active link with interface chip switches on the master control borad link corresponding of the left side.Switch owing to only relate to hardware signal transmission and logic, speed can be controlled at the 10ns rank, and is very fast.
As shown in Figure 5, when business board needs self to finish data link masterslave switchover function, be that business board itself is when having the masterslave switchover function, all be used as the active and standby index signal of using to plate is active and standby with indication/alarm signal and the active and standby indication/alarm signal of using of this plate, the masterslave switchover module is mainly finished the masterslave switchover function according to the state information of this plate with to the active and standby of plate with situation, give master control borad with the active and standby of this plate with information simultaneously, master control borad is selected the switching of respective links according to this signal;
As shown in Figure 6, when business board self is not realized the masterslave switchover function, be that business board itself does not have the masterslave switchover function, and just according to master control borad bring active and standby when selecting the active link of oneself with index signal, active and standby usefulness/alarm signal of plate and the active and standby usefulness/alarm signal of this plate all are used as alarm signal, at this moment do not need the masterslave switchover module, and be alarm module, have alarm function and get final product.Alarm module can not detect the alarm signal that plate is brought, just according to cpu i/f module announcements self working condition determine whether to send alarm signal.At this moment can not need to carry out any communication between the business board, promptly switching between the control logic chip between the business board can not interconnect.
Situation when respectively business board itself being had the masterslave switchover function and not having the masterslave switchover function below describes respectively:
(1) reduces in the application of master control borad burden for needs as far as possible, can select for use switching of business board to be independent of the mode of master control borad, described business board self is finished the masterslave switchover function promptly, and the state that this moment, business board was given master control borad is indicated the active and standby with indicating of business board just itself.Active and standby decide the active link of oneself the same with business board according to what master control borad sent with index signal, master control borad is according to the active and standby active link of determining own interface chip with index signal that send on the business board too, both sides are to do selection with active and standby logical relation with index signal too, the speed of switching is very fast, and logical relation is listed as follows:
Table one business board is active and standby active link with index signal decision interface chip according to master control borad sent
| The active and standby index signal of using of master control borad L | The active and standby index signal of using of master control borad R | Business board XL interface chip active link | Business board XR interface chip active link |
| 0 | 1 | The link 1 of business board XL | The link 1 of business board XR |
| 1 | 0 | The link 2 of business board XL | The link 2 of business board XR |
Table two master control borad is active and standby active link with index signal decision interface chip according to business board sent
| The active and standby index signal of using of business board XL | The active and standby index signal of using of business board XR | Master control borad L interface chip active link | Master control borad R interface chip active link |
| 0 | 1 | The link 1 of master control borad L | The link 1 of master control borad R |
| 1 | 0 | The link 2 of master control borad L | The link 2 of master control borad R |
Business board to switch principle also consistent with master control borad, all be to switch by hard-wired, such as, when the light mouth of business board breaks down, light mouth PHY chip adopts interrupt mode to report CPU, CPU initiatively reduces to oneself standby by the masterslave switchover module, plate (opposite end business board) active and standbyly promptly is upgraded to this plate main using with index signal according to what receive in logic chip, two plates are all sent the active and standby of oneself by active and standby with situation with the index signal line simultaneously, the active and standby index signal of using that master control borad is sent according to two business boards, by link selection module output link switching signal, the active link of switching interface chip, whole handoff procedure adds software interrupt by hardware finishes dealing with, and speed is very fast.
(2) occasion that reduces business board software processes amount as far as possible, reduces cost for needs, can select the mode of the active and standby usefulness of master control borad specified services plate for use, be that business board self is not carried out the masterslave switchover function, can not need to carry out any communication between the business board, promptly switching between the control logic chip between the business board can not interconnect.Business board only needs independently to report the state of oneself and select active link to get final product according to master control borad is active and standby with the index signal line, and this time, the speed of switching depended on the speed that responds when business plate report speed and master control borad are switched for the business board state when breaking down.Such as, when the light mouth of business board breaks down, light mouth PHY chip adopts interrupt mode reporting service plate CPU, CPU control logic chip at once is changed to fault with single board state, and by alarm line AL_ACT or AR_ACT notice master control borad, logic chip has carried out real-time monitoring to the alarm line of business board on master control borad, and reports CPU by the link selection module by interrupt mode when state switches, and is come the active link of switching main-control board interface chip by CPU control link selection module.
The present invention provides a kind of simultaneously and, can accomplish when carrying out the service link switching and will reduce to minimum owing to switch the data of losing the implementation that management data is received and dispatched simultaneously the business datum dual transmitting and receiving on master control borad and business board.Owing to switch the state of all knowing the other side by hardware realization and master control borad and business board, so the present invention switches the very fast and switchover mode flexible and selectable of speed, be applicable to different application scenarios, and master control board switching or business board when the mode that the present invention cooperatively interacts by software and hardware realizes breaking down situation are switched, and can shorten switching time greatly.
Those skilled in the art do not break away from essence of the present invention and spirit, can there be the various deformation scheme to realize the present invention, the above only is the preferable feasible embodiment of the present invention, be not so limit to interest field of the present invention, the equivalence that all utilizations specification of the present invention and accompanying drawing content are done changes, and all is contained within the interest field of the present invention.
