Selecting in debit's case of said system cross board or service processing board, the port protection protocol process module needs according to switching trigger condition the business of active and standby port to be selected receipts.Saidly switch the condition that trigger condition promptly triggers Port Protection Switching.Said port protection protocol process module comprises the host port protection protocol process module of system's cross board or the veneer port protection protocol process module of service processing board.According to the difference of switching the trigger condition source, the present invention will switch trigger condition and be divided into following three types:
The first kind is that order is switched in the outside, and this type of order is to switch trigger condition by what manual work issued, is divided into: remove, switch locking, Forced Switch to main, Forced Switch to be equipped with, Manual Switch to main, Manual Switch to being equipped with etc. six kinds.
The port protection protocol process module to six kinds of result specific descriptions of switching trigger condition of the above-mentioned first kind is:
(1) result to clear command is: remove all external commands and intermediateness, get back to IDLE (free time) state or auto switching state according to active and standby port status;
(2) to the result of switching lock command be: the working port of port protection is switched on the main port, and the residing state of working port this moment is marked as lock-out state;
Lock-out state in said (2) can be seized following five kinds of states: Forced Switch attitude, Manual Switch attitude, auto switching attitude, IDLE attitude, WTR (Wait-to-Restore) attitude.
Said seizing promptly when working port is in certain state, this moment, working port did not respond the switching request of being seized by this state corresponding with other states.
(3) to Forced Switch be: the working port of port protection is switched on the main port, and the residing state of working port this moment is marked as the Forced Switch state to the result of main command;
Forced Switch in said (3) is effective under the non-recovery Switch mode at port protection only to main command.
(4) to Forced Switch be: the working port of port protection is switched on the standby port, and the residing state of working port this moment is marked as the Forced Switch state to being equipped with the process of commands result;
Following four kinds of states can be seized with (4) middle residing Forced Switch state of working port in said (3): Manual Switch attitude, auto switching attitude, IDLE attitude, WTR attitude.
(5) to Manual Switch be: the working port of port protection is switched on the main port, and the residing state of working port this moment is marked as the Manual Switch state to the result of main command;
With Forced Switch in said (3) to main command only port protection be under the non-recovery pattern effectively in like manner; Manual Switch is effective under the non-recovery pattern at port protection only to main command in said (5); And will cause thus if main with or standby port among both arbitrary port down state appears, it is invalid that so said Manual Switch arrives main command.
(6) to Manual Switch be: the working port of port protection is switched on the main port, and the residing state of working port this moment is marked as the Manual Switch state to being equipped with the process of commands result.
It is thus clear that, in said (6) as long as main with or standby port among both arbitrary port down state appears, said Manual Switch is invalid to ordering fully.
The residing Manual Switch state of active and standby port can be seized following two states in said (5) and (6): IDLE attitude, WTR attitude.
Provide of the present invention second type switch trigger condition before, need earlier not having under the situation of external command, the residing state of primary and backup port is done explanation.Do not having under the situation of external command, the residing upstate of primary and backup port can influence the port status at port protection control protocol and work at present port place, main with or standby port state of living in can be divided into three kinds of situations, specifically describe and be:
(7) the service processing board veneer is in off-line state, and promptly the port status test point can't the monitoring port access service, as board software crash, veneer is not on the throne or power down etc.The priority value of this state is 1.
The situation that said (7) are described is equal to port in the ordinary course of things and is in down state.
(8) port is in down state, promptly port break down or access service unavailable, LOS (dropout) or AIS (alarm indication signal) appear like port.The priority value of this state is 1.
(9) port is in state good for use (NR attitude), and promptly the port monitoring function is normal and the port access service is normal.The priority value of this state is 0.
Based on the above-mentioned priority value of leading usefulness or the residing state of standby port, can second type of auto switching trigger condition be divided into following four kinds of auto switching requests:
(10) primary and backup port all is in (9) good for use state, and promptly the priority value of primary and backup port is 0;
(11) primary and backup port all is in down state, and promptly the priority value of primary and backup port is 1;
(12) main port can be used, and standby port is unavailable, and promptly the main port priority value is 0, and the standby port priority value is 1;
(13) main port is unavailable, and standby port can be used, and promptly the main port priority value is 1, and the standby port priority value is 0.
Because outside Manual Switch order of switching in the order is invalid under the arbitrary situation that down state occurs of active and standby port, so back three kinds in four kinds of top auto switching requests can be seized the Manual Switch state.But the auto switching request can not be seized and switched locking, Forced Switch is switched attitude for two kinds.
The port protection protocol process module to the result specific descriptions of above-mentioned four kinds of auto switching trigger conditions is:
(10a) working port remains unchanged, and is marked as IDLE or WTR attitude
(11a) working port remains unchanged, and is marked as auto switching SF attitude
(12a) working port switches to main port by standby port, and is marked as auto switching SF attitude
(13a) working port switches to standby port by main port, and is marked as auto switching SF attitude.
It is thus clear that the result of port protection protocol process module auto switching request is: auto switching SF attitude, IDLE attitude, three kinds of states of WTR attitude.
Remove above-mentioned two types and switch trigger condition; Also exist other to switch trigger condition; Promptly by WTR timer timing termination event; Said incident is the business of leading on usefulness or the standby port and connects, and this switches trigger condition is the recovery pattern at port protection only, and working port must occur under the WTR state.When this trigger condition occurring, the port protection protocol process module can switch to main port with working port, and the state that is provided with is the IDLE attitude.
In sum; The realization of device level port protection provided by the invention technology can solve user side to telecommunications company's local side apparatus between or the problem of service interruption that causes when breaking down of the line attachment between telecommunications company's local side apparatus, and the while can be realized the protection to ports such as PDH port, ethernet port, atm ports.
