Detailed description of the invention
Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
The present invention provides the schematic flow sheet of the method first embodiment that a kind of veneer automatically switches.
The schematic flow sheet of method first embodiment that a kind of veneer automatically switches is provided for the present invention with reference to Fig. 1, Fig. 1.
In the first embodiment, the method that described veneer automatically switches includes:
Step 101, standby board receives the photosphere warning signal of the detector transmission of primary veneer or the photosphere warning signal of the detector transmission of described standby board;
Concrete, when primary veneer detects that line side disconnects, then having and alert generation accordingly, alarm is filtered by primary road plate, only retains the alarm of light mouth, and by communication between plates port, is sent to standby road plate. After standby road plate receives alarm, it is notified that APS controller obtains alarm.
Step 102, described standby board sends, to executor, the backboard expense that switching intersects according to described photosphere warning signal.
Concrete; automatic protection switching (automaticprotectswitch; APS) controller carries out protocol processes after obtaining alarm; judge now to need to switch to standby road plate; then by backboard overhead notification controller, primary cross link can be switched to standby cross link, complete to switch.
Concrete, it is the method schematic diagram that a kind of veneer provided by the invention automatically switches with reference to Fig. 2, Fig. 2, as in figure 2 it is shown, when creating protection group, the communication between plates port of primary road plate and standby road plate is registered. Primary veneer and standby board receive the signal of the business that carries that circuit passes over simultaneously, and under normal circumstances, controller selects the intersection of connection client's plate and primary road plate, solves concrete service signal eventually through client's plate. When primary veneer detects that line side disconnects, then having and alert generation accordingly, alarm is filtered by primary road plate, only retains the alarm of light mouth, and by communication between plates port, is sent to standby road plate. After standby road plate receives alarm, it is notified that APS controller obtains alarm, APS controller carries out protocol processes after obtaining alarm, judge now to need to switch to standby road plate, then by backboard overhead notification controller, primary cross link can be switched to standby cross link, complete to switch, simultaneously, forward the message to webmaster by agent, update the switch status on network management interface. Being disconnected in the of short duration time that intersection has switched (lower than 50ms) in business, have service disconnection, after having switched, client's plate may proceed to the concrete service signal of transmission to client.
In 1+1 protection framework of the present invention, the standby board of all protection circuits, all as independent control unit, is all integrated with controller in service board software, and the corresponding protection group of self protected business is controlled management; Because all protection veneers are all as controller; so; the APS controller on every block protection veneer can be allowed only to be responsible for processing the alarm that the protected business of this protection veneer is correlated with, after namely detector detects alarm, be just transferred to the controller (protection veneer) corresponding to business.
The invention solves the disconnected fibre of single and produce a large amount of alarm problems, in original alarm report, if line side bandwidth is 100G, it is mapped as 80 collection optical fiber distributing unit (OracleDatabaseUnloader, ODU) 0, the disconnected fibre of single will produce 1 light mouth alarm, article 80, scheduled reception alarm, 80 service failure alarms, add up to 161, after adopting the alarm filtering rule of the present invention, it is only necessary to report a light mouth alarm, solve a plurality of line interruption, report the obstructing problem that a large amount of alarm is formed, in original alarm report, a plurality of circuit alarm concentration reports to same controller, easily form message blocking, in the present invention, each detector and controller pairing, form proprietary alarm detection and report passage, avoid message blocking to greatest extent, solve the execution efficiency problem of a large amount of alarm report, adopt the present invention, single reports 500 alarms, can when ensureing not packet loss, gather alarm and receive alarm to controller, total time is lower than 5ms, and then the switching time of satisfied protection system is lower than 50ms, and adopt original alarm transfer mode, under same case, time needs more than 100ms, total switching time of remote overproof requirement, the requirement lower than 50ms of total switching time cannot be met, ITU Telecommunication Standardization Sector (ITUTelecommunicationStandardizationSector, ITU-T) standard regulation protection switch time needs to meet lower than 50ms.
