Embodiment
Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
Loopback refers on loopback place, is directly sent back by service signal along direction when coming.Subsystems unit (veneer) in backboard cross system can realize loop fuction, and, also can realize loop fuction in multiple places of the inside of some subsystem element.The embodiment of the present invention utilizes the loop fuction in backboard cross system, positions the fault of backboard cross system.
Embodiment one
Fig. 2 is the flow chart of the Fault Locating Method of backboard cross system according to the embodiment of the present invention one, and the method mainly comprises the following steps:
Step S202, network management system receives the warning information that the indicating services Signal transmissions from the first test point lost efficacy;
Such as, in figure 3, suppose that the downstream of line side T port is provided with a test point, this test point detects that direction of transfer is the service failure in customer side → line side, sends a warning message to network system.
Step S204, network management system sends loop-back command to backboard cross system, indicates above-mentioned service signal to perform loop-back command on the transmission line of this service signal, and locates according to the execution result of loopback the subsystem element broken down.
Such as, in figure 3, if the warning information that the test point that network management system receives T port downstream, line side sends, then send loop-back command to backboard cross system, indicating services signal client-side system rear end loopback in figure 3, backboard cross system is after receiving this loop-back command, and client-side system rear end in figure 3 performs loopback, if loopback circuit leads to (namely network management system does not receive warning information), then network management system determination fault occurs in line unit.
In the prior art when detecting that backboard cross system breaks down, need artificial localizing faults step by step, thus the efficiency of causing trouble location is lower, maintenance cost is high etc. problem, and in the said method that the embodiment of the present invention one provides, network management system is when receiving warning information, perform loopback by instruction backboard cross system and locate the subsystem element broken down, thus simplify the process of fault location, shorten positioning time, reduce the density that alarm detection point is arranged, save equipment cost, reduce difficulty and the maintenance cost of fault location.
In above-mentioned steps S204, network management system can select the loopback port of service signal loopback on the transmission line of service signal, then sends loop-back command to backboard cross system, and indicating services signal performs loopback at this loopback port.At service signal after this port performs loopback, if network management system receives the warning information of test point (i.e. the second test point), then can determine in the subsystem element that fault occurs on current loopback circuit, otherwise network management system can determine that fault occurs in the subsystem element outside current loopback circuit of backboard cross system.Such as, in figure 3, if network management system instruction from the service signal in customer side → line side at client-side system rear end loopback, then service signal performs loopback at the arrival end of line unit, flow to the T port of customer unit, if T port is provided with test point, this test point detects warning information, current loopback service interruption is then described, fault occurs on cross unit or customer unit, if this test point does not detect warning information, then illustrate that current loopback circuit leads to, fault occurs on line unit.
In actual applications, network management system can select arbitrary port on the transmission line of this service signal as loopback port, to improve the efficiency of fault location further according to embody rule.Such as, rule of thumb, customer unit easily breaks down in figure 3, then network management system is after the warning information of test point receiving T port downstream, line side, send the loopback instruction of the client-side system front end loopback of indicating services signal shown in Fig. 3, backboard cross system is after receiving this loopback instruction, service signal is at client-side system front end loopback, if the test point of customer side T port detects that service signal lost efficacy, and send a warning message to network management system, then network management system can determine that customer unit breaks down.Or network management system also can select the loopback circuit comprising maximum subsystem element, such as, indicating services signal is at FTP client FTP rear end loopback in figure 3.
If when network management system determination fault occurs in the subsystem element on current loopback circuit, if the subsystem element on current loopback circuit is multiple, then network management system can send loop-back command to backboard cross system further, reduce current loopback circuit, indicating services signal (can be adjacent at the upper upstream port once performing the loopback port of loopback, also can be non-conterminous) perform loopback to determine the subsystem element broken down, particularly, can following steps be performed:
Step 1, network management system sends loop-back command to backboard cross system, and indicating services signal performs loopback at the upper upstream port once performing the loopback port of loopback;
Step 2, network management system judges whether the warning information receiving test point, if, then determine that fault occurs in the subsystem element of current loopback circuit, if the subsystem element of current loopback circuit only has one, then fault occurs in this subsystem element, otherwise, return and perform step 1; If network management system does not receive warning information, then determine in the subsystem element that fault occurs between current loopback port and the last loopback port selected.
Such as, in figure 3, if service signal performs loopback in client-side system rear end, network management system receives warning information, then determine that fault occurs on customer unit or cross unit, then network management system sends loop-back command further, indicating services signal performs loopback at the R port of customer side, if still produce warning information, then determines that customer unit breaks down, otherwise, determine that cross unit breaks down.
If in step 2 above, subsystem element between current loopback port and the last loopback port selected is multiple, then network management system continues to send loop-back command to backboard cross system, indicating services signal current loopback port and on loopback port once between loopback port perform loopback, until the subsystem element specifically broken down can be determined according to loopback execution result.
When network management system determination fault occurs in the subsystem element outside current loopback circuit, and the subsystem element outside current loopback circuit is when being multiple, network management system can perform loopback by indicating services signal all the other loopback ports outside current loopback circuit further, to determine the concrete subsystem element broken down, specifically can comprise the following steps:
Step 1, network management system sends loop-back command to backboard cross system, and the downstream port (can be adjacent, also can be non-conterminous, be preferably adjacent) that indicating services signal once performs the loopback port of loopback in backboard cross unit upper performs loopback;
Step 2, network management system judges whether to receive warning information, if, then network management system determination fault occurs in the subsystem element between current loopback port and the last loopback port performing loopback, otherwise, network management system determination fault occurs in the subsystem element outside current loopback circuit, if the subsystem element outside current loopback circuit is multiple, then returns and performs step 1.
In step 2 above, if the subsystem element between current loopback port and the last loopback port performing loopback is multiple, then network management system continue indicating services signal current loopback port and on once perform loopback loopback port between loopback port on perform loopback, until the subsystem element broken down can be determined according to loopback result.
In actual applications, when certain service signal normal transmission circuit via subsystem element more time, network management system is when first time, indicating services signal performed loopback, can indicating services signal be positioned at normal transmission circuit centre subsystem element enter and/or outbound port perform loopback, the efficiency of fault location can be improved so further.
In actual applications, the loopback port that network management system indicating services signal performs loopback can be positioned at the inbound port of this service signal at the subsystems unit of backboard cross system, if the loopback port of client-side system rear end loopback in Fig. 3 is at the inbound port of line unit, also the outbound port of subsystem element unit can be positioned at, if the loopback port of client-side system front end loopback in Fig. 4 is at the outbound port of cross unit, or, also all loopback can be carried out at the inbound port of certain line unit and outbound port, thus can determine that fault is front end or rear end that certain subsystem element occurs.
In actual applications, if the modules of certain subsystem element inside also can realize loop fuction, then after determining that this subsystem element breaks down, network management system can also to backboard intersect subsystem send loop-back command, indicating services signal performs loopback, to determine the module broken down at the modules place of the inside of this subsystem element respectively.Such as, in Figure 5, certain subsystem element comprises A, B, C and D tetra-modules, each module can realize loopback, then for the business from customer side to line side, first backboard intersects subsystem can indicating services signal (also can be modules A or B at module C, specifically can determine according to demand) place's execution loopback, if loopback circuit leads to, then determination module D breaks down, otherwise network management system can continue indicating services signal and perform loopback at module B place, until determine the module broken down.
