Number of dropped packets
In order to be better understood from above-mentioned lost package constant current journey really, illustrate below in conjunction with preferred embodiment:
The preferred embodiment of the present invention is by the way of amendment LMM, LMR message format, by forwarding module in the network equipment
Data stream statistics on message CPU module calculate, thus calculate link circuit condition.Figure 12 is excellent according to the present invention
Select LMM, LMR process chart of embodiment, as shown in figure 12, network a and the mutual communication of network b, number
According to stream through network equipment a, network equipment b, after LM opens, corresponding interface can carry out message system to data stream
Meter.
Figure 13 is that the forwarding face according to the preferred embodiment of the present invention enters to Message processing flow chart, and Figure 14 is according to the present invention
The forwarding face of preferred embodiment goes out to Message processing flow chart, and acquiescence LM function is opened on network equipment a below, knot
Close Figure 10, Figure 13, Figure 14 and tell about the idiographic flow of the lower preferred embodiment of the present invention:
Step 101: with reference to Figure 14, data stream mails to network equipment b from network equipment a, message comes to enter from exchange
Row packet parsing, is the discovery that data message, finds a mouthful port attribute list (p+v in Figure 14) and obtains in exit list
LM enabler flags position and the counting index of LM carry out counting messages, platform issues LMM message and passes through simultaneously
Forwarding module packet parsing, finds mouthful port attribute list and obtains LM counting index, read the value in corresponding enumerator,
Numerical value is encapsulated in the TxFCf in LMM message, then mails to network equipment b；
Step 102: receive, with reference to Figure 13, network equipment b, the message that network equipment a comes, carry out packet parsing,
The when of being the discovery that data message, look into port attribute table and obtain LM enabler flags position and obtain counter address and count,
It is the discovery that LMM message is looked into port attribute table and obtained enumerator and the value that reads in enumerator is encapsulated in LMM message
In RxFCf, and transmitted to CPU；
Step 103: after platform CPU receives LMM message, builds LMR message, and by LMM message
TxFCf, RxFCf field values copies to be issued to forwarding face in TxFCf, RxFCf field in LMR message,
Forwarding face such as Figure 12 carries out looking into port attribute table after analytic message is the discovery that LMR message and obtains counter address, and will
The count value read mails to network equipment a after being encapsulated in TxFCb field；
Step 104: network equipment a receives the LMR message that opposite equip. comes, forwarding face such as Figure 13 carries out message
Resolve and look into port attribute table and obtain counter address, from counter address, obtain count value be encapsulated in LMR message
In RxFCb, above give CPU.
Platform is done as follows after receiving LMR message:
1, network equipment a is according to receiving the packet counting of current period in the LMR message in two adjacent cycles:
TxFCf[tc]、RxFCf[tc]、TxFCb[tc]、RxFCb[tc]；The LMR counting in previous cycle: TxFCf [tp],
RxFCf [tp], TxFCb [tp], RxFCb [tp], according to Y.1731 calculating this cycle this locality/far-end packet loss data:
FrameRemoteLoss:|TxFCb[tc]-TxFCb[tp]|-|RxFCb[tc]-RxFCb[tp]|
FrameLocalLoss:|TxFCf[tc]-TxFCf[tp]|-|RxFCf[tc]-RxFCf[tp]|
According to formula: max{a0, a1 ..., an}=max{max{a0, a1 ..., an-1}, an}
2, this locality/far-end before this cycle of CPU module (Pre_HighFrameLocalLoss,
Pre_HighFrameRemoteLoss) packet loss peak value is deposited in data base and is compared with current this locality/far-end value, calculates
Current this locality/far-end packet loss peak value:
HighFrameLocalLoss=max{Pre_HighFrameLocalLoss, FrameLocalLoss}；
HighFrameRemoteLoss=max{Pre_HighFrameRemoteLoss,
FrameRemoteLoss}；
3, giving out a contract for a project several FrameLocalSend=| TxFCf [tc]-TxFCf [tp] | according to this locality, far-end is transmitted messages number
FrameRemoteSend=| TxFCb [tc]-TxFCb [tp] | is further according to formula: ∑ an=∑ an-1+an,
CPU packet loss counting of always being given out a contract for a project by this locality/far-end before this cycle is stored in the data structure of this session respectively and is respectively as follows:
Pre_TotalFrameLocalSend、Pre_TotalFrameRemoteSend、Pre_
TotalFrameLocalLoss, Pre_TotalFrameRemoteLoss can calculate:
TotalFrameRemoteSend=Pre_TotalFrameRemoteSend+FrameRemot eSend
TotalFrameLocalSend=Pre_TotalFrameLocalSend+FrameLocalSe nd
TotalFrameLocalLoss=Pre_TotalFrameLocalLoss+FrameLocalLo ss
TotalFrameRemoteLoss=Pre_TotalFrameRemoteLoss+FrameRemot eLoss
4, always give out a contract for a project number according to this locality/far-end and this locality/far-end packet loss sum can count out the packet loss of local far-end:
FrameRemoteLossRatio=TotalFrameRemoteLoss
/TotalFrameRemoteSend*100/100；
FrameLocalLossRatio=TotalFrameLocalLoss/TotalFrameLocalS end*100/100.
In networking as shown in figure 12, network a forwards with network b mutual flow, and networking requirement can be by certain time
Interior number of dropped packets and overall packet loss are visible, and network a and network b sends out flow, mutually at network equipment a or the network equipment
Configuring EFT-LM on b, periodically there is data message statistical counting one end of configuration ETH-LM toward opposite end hair band
LMM message, opposite end responds LMR message after receiving message and the cycle is carried out.One end of configuration LM can be to LMR
Data in message calculate according to the algorithm of the present invention, and show the most on the display device, facilitate network
Attendant's real-time servicing to network.
It should be noted that for networking as shown in figure 12, both-end LOF can also be realized equally and measures.Respectively
In network equipment a, network equipment b configuration, LM function is opened, transmitting-receiving LMM, LMR report in both sides meeting cycle
Literary composition.Realize process according to above-mentioned, required LOF system can be demonstrated at network equipment a, network equipment b respectively
Meter.
In sum, the embodiment of the present invention has reached techniques below effect: solve in correlation technique, calculate local or
Have to participate in and the problem such as the process that causes is loaded down with trivial details by forwarding module during person's far-end lost package, facilitate forwarding module
Maintenance, greatly facilitate the process determining locally or remotely lost package.
