Embodiment
Hereinafter will describe the present invention with reference to the accompanying drawings and in conjunction with the embodiments in detail.Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.
Loopback is meant that on the loopback place direction directly sent and goes back when the service signal edge was come.Can realize loop fuction on each subsystem element (veneer) in the backboard cross system, and, also can realize loop fuction in a plurality of places of the inside of some subsystem element.The embodiment of the invention is utilized the loop fuction in the backboard cross system, and the fault of backboard cross system is positioned.
Embodiment one
Fig. 2 is the flow chart according to the Fault Locating Method of the backboard cross system of the embodiment of the invention one, and this method mainly may further comprise the steps:
Step S202, network management system receives the warning information from the indicating services signal transmission failure of first test point;
For example, in Fig. 3, suppose that the downstream of line side T port is provided with a test point, this test point detects the service failure of direction of transfer for client side → line side, sends a warning message to network system.
Step S204, network management system toward back plate cross system sends the loopback order, indicates above-mentioned service signal to carry out the loopback order on the transmission line of this service signal, and locatees the subsystem element that breaks down according to the execution result of loopback.
For example, in Fig. 3, if network management system receives the warning information that the test point in T port downstream, line side sends, then the toward back plate cross system sends the loopback order, the client side system rear end loopback of indicating services signal in Fig. 3, backboard cross system are after receiving this loopback order, and loopback is carried out in the client's side system rear end in Fig. 3, if loopback link tester (being that network management system does not receive warning information), then network management system determines that fault occurs in line unit.
In the prior art when detecting backboard cross system and break down, need manually fault location step by step, thereby problems such as the efficient that causes fault location is lower, maintenance cost height, and in the said method that the embodiment of the invention one provides, network management system is when receiving warning information, carry out the subsystem element that breaks down in the loopback location by the indication backboard cross system, thereby simplified the process of fault location, shortened positioning time, reduced the density that alarm detection point is provided with, save equipment cost, reduced the difficulty and the maintenance cost of fault location.
In above-mentioned steps S204, network management system can be selected the loopback port of service signal loopback on the transmission line of service signal, and the toward back plate cross system sends the loopback order then, and the indicating services signal is carried out loopback at this loopback port.At service signal after this port is carried out loopback, if network management system receives the warning information of test point (i.e. second test point), can determine that then fault occurs on the subsystem element on the current loopback circuit, otherwise, network management system can determine fault occur in backboard cross system on the subsystem element outside the current loopback circuit.For example, in Fig. 3, if network management system indication from the service signal in client side → line side at client's side system rear end loopback, then service signal is carried out loopback at the arrival end of line unit, flow to the T port of client unit, if the T port is provided with test point, this test point detects warning information, current loopback service interruption then is described, fault occurs on cross unit or the client unit, if this test point does not detect warning information, current loopback link tester then is described, fault occurs on the line unit.
In actual applications, network management system can be according to the arbitrary port on the transmission line of concrete this service signal of application choice as the loopback port, with the efficient of further raising fault location.For example, rule of thumb, the client is broken down the unit easily in Fig. 3, then network management system is behind the warning information of the test point that receives T port downstream, line side, send of the loopback instruction of indicating services signal at client's side system front end loopback shown in Figure 3, backboard cross system is after receiving this loopback instruction, service signal is at client's side system front end loopback, if detecting service signal, the test point of client's side T port lost efficacy, and send a warning message to network management system, then network management system can determine that the client unit breaks down.Perhaps, network management system also can select to comprise the loopback circuit of maximum subsystem element, and for example, the indication service signal is at FTP client FTP rear end loopback in Fig. 3.
When if network management system determines that fault occurs on the subsystem element on the current loopback circuit, if the subsystem element on the current loopback circuit is a plurality of, then further toward back plate cross system transmission loopback order of network management system, dwindle current loopback circuit, the indicating services signal (can be adjacent at the last upstream port of once carrying out the loopback port of loopback, also can be non-conterminous) carry out the subsystem element of loopback to determine to break down, particularly, can carry out following steps:
Step 1, network management system toward back plate cross system sends the loopback order, and the indicating services signal is carried out loopback at the last upstream port of once carrying out the loopback port of loopback;
For example, in Fig. 3, if service signal is carried out loopback in client's side system rear end, network management system receives warning information, determines that then fault occurs on client unit or the cross unit, then network management system further sends the loopback order, the indicating services signal is carried out loopback at the R of client's side port, if still produce warning information, determines that then the client unit breaks down, otherwise, determine that cross unit breaks down.
If in above-mentioned steps 2, subsystem element between current loopback port and the last loopback port of selecting is a plurality of, then network management system toward back plate cross system continues to send the loopback order, the indicating services signal current loopback port and on once the loopback port between the loopback port carry out loopback, until determining the subsystem element that specifically breaks down according to the loopback execution result.
Determining fault when network management system occurs on the subsystem element outside the current loopback circuit, and the outer subsystem element of current loopback circuit is when being a plurality of, network management system further indicating services signal all the other loopback ports outside current loopback circuit is carried out loopback, concrete subsystem element to determine to break down specifically can may further comprise the steps:
Step 1, network management system toward back plate cross system send the loopback order, and the indicating services signal is once carried out the downstream port (can be adjacent, also can be non-conterminous, be preferably adjacent) of the loopback port of loopback and carried out loopback on the backboard cross unit;
In above-mentioned steps 2, if the subsystem element between the loopback port of current loopback port and last execution loopback is a plurality of, then network management system continue the indicating services signal current loopback port and on once carry out on the loopback port between the loopback port of loopback and carry out loopback, until the subsystem element that can determine according to the loopback result to break down.
In actual applications, when the normal transmission circuit of certain service signal via subsystem element more for a long time, network management system is when the first time, the indicating services signal was carried out loopback, can the indicating services signal the subsystem element of the centre that is positioned at the normal transmission circuit go into and/or outbound port is carried out loopback, can further improve the efficient of fault location like this.
In actual applications, the loopback port that network management system indicating services signal is carried out loopback can be positioned at the inbound port of this service signal in each subsystem element of backboard cross system, as the loopback port of client's side system rear end loopback among Fig. 3 inbound port at line unit, also can be positioned at the outbound port of subsystem element unit, as the loopback port of client's side system front end loopback among Fig. 4 outbound port at cross unit, perhaps, also can all carry out loopback, thereby can determine that fault is front end or the rear end that certain subsystem element takes place at the inbound port and the outbound port of certain line unit.
In actual applications, if each module of certain subsystem element inside also can realize loop fuction, then after definite this subsystem element breaks down, network management system can also send the loopback order by toward back plate intersection subsystem, the indicating services signal is carried out loopback at each module place of the inside of this subsystem element respectively, with the module of determining to break down.For example, in Fig. 5, certain subsystem element comprises A, B, C and four modules of D, each module can realize loopback, then for business from client's side to the line side, backboard intersection subsystem can the indicating services signal (also can be modules A or B at module C at first, specifically can determine according to demand) locate to carry out loopback, if loopback link tester, then determination module D breaks down, otherwise network management system can continue the indicating services signal and carry out loopback at module B place, until determining the module that breaks down.
