Embodiment
Functional overview
Consider in the correlation technique that the embodiment of the invention provides the detection method and the device of link performance to the problem of the Performance Detection more complicated of link, this method comprises: gather the performance parameter on the link; Judge according to described performance parameter whether link exists fault.
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
Method embodiment
According to embodiments of the invention, provide a kind of detection method of link performance.
Fig. 3 is the flow chart according to the detection method of the link performance of the embodiment of the invention.
As shown in Figure 3, this method comprises that following step S302 is to step S304:
Step S302 gathers the performance parameter on the link;
Step S304 judges according to described performance parameter whether described link exists fault.
Be described in detail below in conjunction with the implementation procedure of example the embodiment of the invention.
For realize to virtual bridge local area network (LAN) check, the report of isolation and connectivity fault, have following mechanism:
1, by a plurality of nested maintenance fields of the network configuration of a bridge network or a bridge network (Maintenance Domains abbreviates MD as).
2, in given arbitrarily bridge and one group of VLAN, dispose the maintenance associating (Maintenance Association abbreviates MA as) that identifies with an independent MD.
3, the agreement, flow process and the CFM protocol massages form that are used for detecting, isolating the connectivity fault report.
4, the allocative abilities of configuration and management maintenance point (Maintenance Point abbreviates MP as) in MA, MP is used for producing corresponding CFM message.
5, order MPs carries out the Fault Isolation operation of determining and checks (inspect) result.
The type of data packet that defines in CFM is as follows:
1, continuity check message (Continuity Check Message abbreviates CCM as): the CFM protocol Data Unit of a multicast.It is periodically sent to confirm the continuity on this MA passed through of MEP that MA has by a MEP.The MP that receives CCM does not respond this message.
2, the CFM PDU that link trace message (Linktrace Message abbreviates LTM as): MEP initiates is used for following the trail of the path that arrives a destination-mac address from MIP to MIP, arrives its purpose MP or can not be forwarded again up to LTM.Each produces a LTR to the MP in the path of target.
3, link trace response (Linktrace Reply abbreviates LTR as): MP receives LTM and sends to the unicast message of this MEP from MEP in response.
4, loopback message (Loopback Message abbreviates LBM as): a MEP sends to the clean culture CFM PDU of the MP of an appointment, and expectation receives LBR.
5, loopback response (Loopback Reply abbreviates LBR as): the LBM that MP receives from MEP in response and the unicast message that sends to this MEP.
By the packet sending and receiving of above definition, can be achieved as follows function:
1, path discovery: MEP uses LTM/LTR message to find, follows the tracks of a MEP arrive between another one MEP or the MIP the path of process;
2, fault-finding: the CCM message that the MEP life cycle sends and receives is come the detection of connectivity to network, mainly can detect to be communicated with failure and connectedness (situation of incorrect link) unwillingly.
3, fault recognition and isolation: this function belongs to managerial behavior, and the keeper carries out the affirmation of Trouble ticket by LBM/LBR.Carry out certain isolated operation then.
4, fault notification: when the MEP direction has failure of connectivity, can send the management system (NMS, TRAP etc.) of relevant report information to appointment.
Fig. 4 is the flow chart according to the detection method of the preferred link performance of the embodiment of the invention.
As shown in Figure 4, the detection method according to the preferred link performance of the embodiment of the invention can may further comprise the steps:
Step S401, the overall CFM enable switch of all devices is opened in the network that the needs of selecting are detected, so that the transmission of message.
Step S402 according to network size, marks off MD.
Step S403, the maintenance field MD that selects needs to detect according to the difference of VLAN, creates and safeguards associating MA.
Step S404 selects a MA, thereon according to being edge device or internal unit, creating MEP and MIP respectively and is tied on the concrete equipment physical port.
Step S405 on the MEP that creates, opens LM, DM and enables.
Through above step, in network environment, the environmental structure of CFM to be got up, this moment, MEP can periodically send the LMM frame to the MA at its place, and frame LMR is returned in reception in real time.After MEP receives the LMR frame, among the MIB of the equipment that records that the time stamp link datas such as (TxTimestampf) when this MEP can send: far-end time of reception (RxTimef) that counting (TxFCf), far-end count pick up (RxFCb), local terminal send counting (TxFCb), local terminal count pick up (RxFCl), DM frame, DM transmission is real-time.
Step S406 opens the SNMP NM server, can pass through webmastering software control operation network element device like this, reaches the purpose of management, monitoring.
Step S407, the unlatching link data is gathered, property program loop from the MIB database of the MEP node of network element device configuration, read performance parameter on the current link, the time stamp (TxTimestampf) when comprising time of reception (RxTimef) that far-end sends counting (TxFCf), far-end count pick up (RxFCb), local terminal and send counting (TxFCb), local terminal count pick up (RxFCl), DM frame, DM transmission etc.
Step S408, link data filters and gathers, this MEP that system will collect goes up the counting that sends and receive bag, calculates local terminal packet loss ((TxFCb-RxFCb)/TxFCb), far-end packet loss ((TxFCf-RxFCl)/TxFCf), frame time delay (RxTimef-TxTimeStampf).Performance numbers such as the local terminal packet loss that calculates, far-end packet loss, frame time delay are stored in the network management data storehouse.During the maximum packet loss that is provided with greater than system when the packet loss that calculates (local terminal packet loss or far-end packet loss) (for example 30%), perhaps, show that fault has appearred in current link when the frame time delay of calculating during greater than the threshold value preset.Realize the function of link failure detection;
Preferably, in the present invention, also can judge directly whether link exists fault by the performance parameter of gathering on the link, such as receiving counting and local terminal transmission counting by distant termination, perhaps relatively the relation between local terminal count pick up and the far-end transmission counting is judged, if far-end count pick up and local terminal send counting, perhaps relatively the difference between local terminal count pick up and the far-end transmission counting surpasses default threshold value, judges that then there is fault in link.
Step S409 when maximum packet loss that packet loss is provided with greater than system, sends an alarm for immediately the SNMP webmaster,
Step S410, link performance show, with the link performance data that collection gathers, are latitude with time, with one hour, one day, different cycles such as a week, a year, show with the form of tendency chart, are presented in the performance trend of link in this cycle.Realize the function that link performance detects.
As can be seen from the above description, the present invention has realized that quicklook ground detects the effect of link performance.
