Embodiment
For enabling above-mentioned purpose, the feature and advantage of the application more become apparent, below in conjunction with the drawings and specific embodiments, the application is described in further detail.
The main reason that Ethernet link storm produces is exactly there is loop in Ethernet link, if the processor of PC end or board sends broadcast packet in this case, this broadcast packet can forward with the exchanged chip of the speed be exceedingly fast in the loop.In theory, the speed of the shorter forwarding of length of broadcast packet is faster, and the burden caused processor is also larger.Thus the situation of packet obstruction can be formed, the control desk of base station also there will be and cannot connect the phenomenons such as board.
In order to adapt to the demand of external field environment, must accomplish that board slot can flexible configuration, this just may produce loop in Ethernet link.For this reason, present applicant proposes the method and apparatus that a kind of Ethernet link storm detects and suppresses, detected and suppress the generation of storm by exchange chip; When storm being detected, cut off the Ethernet link producing storm, open-loop, broadcast packet is made to circulate in Ethernet link, remove the address resolution logic list item (AddressResolutionLogic, ARL) that self study is arrived simultaneously, allow exchange chip relearn the MAC Address of clean culture, and the port static of telecommunication network processor and exchange chip being bound, guaranteeing to control exchange chip in Telnet base station when there is storm; The Ethernet link cut off before being communicated with again after storm disappears.The impact of broadcast storm on base station can be reduced by this mechanism, not hinder again the transmission of business datum simultaneously.
A kind of Ethernet link storm detection that the application proposes and the method and apparatus suppressed is introduced in detail below by enumerating several specific embodiment.
Embodiment one, introduces a kind of Ethernet link storm detection that the application proposes and the method suppressed in detail.
With reference to Fig. 1, show the method flow diagram that described in the embodiment of the present application one, a kind of Ethernet link storm detects and suppresses.
Step 11, arranges the forwarding rate threshold value of each forwarding port according to maximum bandwidth forwarding port each in exchange chip;
During broadcast storm in Ethernet link the forwarding rate of packet far away higher than transmission regular traffic data time speed, so can according to maximum bandwidth forwarding port each in exchange chip, forwarding rate threshold value is set to each forwarding port, guarantees that the forwarding rate of each forwarding port under regular traffic can not reach forwarding rate threshold value.
Such as, the maximum bandwidth forwarding port A is 1000Mbps, and the maximum bandwidth forwarding port B is 100Mbps, and can arrange the forwarding rate threshold value forwarding port A is 500Mbps, and arranging the forwarding rate threshold value forwarding port B is 50Mbps.
Step 12, detects the forwarding rate of each forwarding port;
In Ethernet link, the moment detects the forwarding rate of each forwarding port.
The forwarding rate of each forwarding port can be detected by third-party rate detection instrument or application program.
Such as, detect that the forwarding rate forwarding port A is 50Mbps; Detect that the forwarding rate forwarding port B is 50Mbps.
Step 13, judges whether described forwarding rate is more than or equal to the corresponding forwarding rate threshold value forwarding port;
After detection obtains the forwarding rate of each forwarding port in step 12, the forwarding rate threshold value of described forwarding rate with corresponding forwarding port is compared, judge whether described forwarding rate is more than or equal to the corresponding forwarding rate threshold value forwarding port.
The forwarding rate 50Mbps of the forwarding port A detected and the forwarding rate threshold value 500Mbps forwarding port A are compared, judges that the forwarding rate forwarding port A is not greater than or equal to, be namely less than the forwarding rate threshold value forwarding port A.
The forwarding rate 50Mbps of the forwarding port B detected and the forwarding rate threshold value 50Mbps forwarding port B are compared, the forwarding rate judging to forward port B equals the forwarding rate threshold value forwarding port B.
Step 14, when being more than or equal to, closes this forwarding port.
The forwarding rate of each forwarding port is once reach the corresponding forwarding rate threshold value forwarding port, namely the forwarding rate of each forwarding port is greater than or equal to the corresponding forwarding rate threshold value forwarding port, illustrate that in base station, abnormal conditions have appearred in Ethernet link, create broadcast storm.
In step 13, judge that the forwarding rate forwarding port A is less than the forwarding rate threshold value forwarding port A, illustrate in Ethernet link and do not produce broadcast storm, do not close and forward port A.
In step 13, the forwarding rate judging to forward port B equals the forwarding rate threshold value forwarding port B, illustrates in Ethernet link and produces broadcast storm, then close and forward port B, suppress the broadcast storm produced.
In sum, the method that a kind of Ethernet link storm that the embodiment of the present application one proposes detects and suppresses, compared with prior art, has the following advantages:
The method that a kind of Ethernet link storm that the embodiment of the present application one proposes detects and suppresses, by arranging the forwarding rate threshold value of each port of exchange chip, when the forwarding rate of port is more than or equal to forwarding rate threshold value, close this port, cut off redundant link; By suppressing storm to the dynamic cut-out of Ethernet link, making the configuration of Ethernet link more flexible, certain Ethernet link can be closed according to the concrete condition of base station, better meet the demand of practical application.
Embodiment two, introduces a kind of Ethernet link storm detection that the application proposes and the method suppressed in detail.
With reference to Fig. 2, show the method flow diagram that described in the embodiment of the present application two, a kind of Ethernet link storm detects and suppresses.
Step 21, arranges the forwarding rate threshold value of each forwarding port according to maximum bandwidth forwarding port each in exchange chip;
According to maximum bandwidth forwarding port each in exchange chip, forwarding rate threshold value is set to each forwarding port, guarantees that the forwarding rate of each forwarding port under regular traffic can not reach forwarding rate threshold value.
Arranging each forwarding rate threshold value forwarding port in exchange chip is 1/2nd of each forwarding port maximum bandwidth.
Because Ethernet link packet forwarding rate during broadcast storm is close to the maximum bandwidth forwarding port, respectively forward the forwarding peak speed of port in conjunction with base station when real work, the forwarding rate thresholding of each forwarding port is set to correspondingly forward 1/2nd of the maximum bandwidth of port.So both ensure that the transfer of data of regular traffic, in turn ensure that and broadcast storm can be detected in time.
Such as, the maximum bandwidth forwarding port A is 1000Mbps, and can arrange the forwarding rate threshold value forwarding port A is 500Mbps; The maximum bandwidth forwarding port B is 100Mbps, and can arrange the forwarding rate threshold value forwarding port B is 50Mbps.
Step 22, detects the forwarding rate of each forwarding port;
The forwarding rate of each forwarding port can be detected by third-party rate detection instrument or application program; If exchange chip can detect the forwarding rate of each forwarding port automatically, then directly can read out the forwarding rate of each forwarding port from exchange chip.
Such as, detect that forwarding port A is 200Mbps at the forwarding rate in T1 moment; Forwarding port B is 60Mbps at the forwarding rate in T2 moment.
Step 23, judges whether described forwarding rate is more than or equal to the corresponding forwarding rate threshold value forwarding port;
The forwarding rate of the forwarding port A detected in step 22 and the forwarding rate threshold value forwarding port A are compared, judges whether the forwarding rate forwarding port A is greater than or equal to the forwarding rate threshold value forwarding port A.
The forwarding rate of the forwarding port B detected in step 22 and the forwarding rate threshold value forwarding port B are compared, judges whether the forwarding rate forwarding port B is greater than or equal to the forwarding rate threshold value forwarding port B.
Forward port A and be less than the forwarding rate threshold value 500Mbps forwarding port A at the forwarding rate 200Mbps in T1 moment;
Forward port B and be greater than the forwarding rate threshold value 50Mbps forwarding port B at the forwarding rate 60Mbps in T2 moment.
Step 24, when being more than or equal to, closes this forwarding port;
Judge in step 23 that forwarding port B is greater than the forwarding rate threshold value 50Mbps forwarding port B at the forwarding rate 60Mbps in T2 moment.
When the forwarding rate forwarding port is greater than the forwarding rate threshold value forwarding port, broadcast storm will be produced, suppress broadcast storm if do not taken measures, in Ethernet link, ceaselessly with close to the speed forwarding data bag forwarding port maximum bandwidth, network blockage will be caused.
Fig. 3 is with wireshark(network package analysis software when there is Ethernet link storm in base station) capture the schematic diagram of inside of base station ether bag.
As shown in Figure 3, when there is broadcast storm in Ethernet link, exchange chip can forward broadcast data packet with the fastest forwarding rate, and the interval between two broadcast data packet approximately only has 10us; Owing to ceaselessly forwarding broadcast data packet with the fastest forwarding rate in Ethernet link, base station control station is caused to disconnect with the connection of board, PC end is owing to utilizing wireshark to grab a large amount of broadcast data packet simultaneously, there will be the situation that the speed of service is obviously slack-off.
When judging in step 23 that forwarding port B is greater than at the forwarding rate 60Mbps in T2 moment the forwarding rate threshold value 50Mbps forwarding port B, closing and forwarding port B.
There is Ethernet link storm in Fig. 4, and when suppressing Ethernet link storm, captures the schematic diagram of inside of base station ether bag with wireshark in base station.
As shown in Figure 4, when broadcast storm being detected and after suppressing broadcast storm, the broadcast data packet forwarded with the fastest forwarding rate in Ethernet link can be blocked and throw away by exchanged chip port, thus enables normal packet transmit in Ethernet link.When there is broadcast storm, only close the forwarding port producing broadcast storm place Ethernet link, other forwarding ports being in normal traffic state still carry out the forwarding of normal data packet.
Step 25, when forwarding port shutdown, detects the forwarding rate of this forwarding port;
When forwarding port B and closing because its forwarding rate is more than or equal to its forwarding rate threshold value, still detect the forwarding rate forwarding port B.
Such as, detect that the forwarding rate forwarding the T3 moment of port B after closedown is 30Mbps; Be 20Mbps at the forwarding rate in T4 moment.
Step 26, judges whether described forwarding rate is less than this forwarding port repeat rate threshold value;
The forwarding rate of the forwarding port B detected in step 25 and its forwarding rate threshold value are compared, judges whether the forwarding rate forwarding port B is less than its forwarding rate threshold value.
Forward port B and be less than its forwarding rate threshold value 50Mbps at the forwarding rate 30Mbps in T3 moment; Forward port B and be less than its forwarding rate threshold value 50Mbps at the forwarding rate 20Mbps in T4 moment.
Step 27, when being less than, opens this forwarding port.
When the forwarding rate forwarding port B is less than its forwarding rate threshold value, opens and forward port B.
Just in order to the forwarding port of closing before opening after broadcast storm is totally constrained as far as possible, time that described forwarding rate is less than this forwarding port repeat rate threshold value can be worked as when being greater than the time preset, open this forwarding port.
Such as, the time preset is 10s, also can preset other time according to actual conditions.When the forwarding rate of forwarding port B between T3 and the T4 moment is less than its forwarding rate threshold value all the time, and when the time period between T3 and the T4 moment is greater than 10s, opens and forward port B.
Meanwhile, in order to adapt under external field environment can Telnet base station, associative operation is carried out to the exchange chip in board, especially when there is broadcast storm, can orientation problem, adjustment software merit rating, extract base station information etc.The port of the network address of Telnet base station and exchange chip can be carried out static binding.When being remotely logged into base station, by the binding relationship of the network address and switching chip port, directly associative operation can be carried out to exchange chip.

Judge that forwarding port A exceedes its forwarding rate threshold value 500Mbps at the forwarding rate 600Mbps in T6 moment; Judge that forwarding port A does not exceed its forwarding rate threshold value 500Mbps at the forwarding rate 300Mbps in T7 moment.
And when forwarding rate does not exceed its forwarding rate threshold value, continue to detect its subsequent time forwarding rate.
Step 34, if forwarding rate exceedes its forwarding rate threshold value, closes this forwarding port;
Forward port A and exceed its forwarding rate threshold value 500Mbps at the forwarding rate 600Mbps in T6 moment, port A will be forwarded and close.
Step 35, speed to be forwarded is less than its forwarding rate threshold value, and keeps a period of time, reopens this forwarding port.
