Embodiment
For above-mentioned purpose, the feature and advantage that make the application can become apparent more, below in conjunction with the drawings and specific embodiments the application is described in further detail.
The main reason that the Ethernet link storm produces is exactly to have loop in the Ethernet link, if the processor of PC end or integrated circuit board sends broadcast packet in this case, this broadcast packet can be transmitted with the exchanged chip of the speed that is exceedingly fast in loop.In theory, the speed of the shorter forwarding of length of broadcast packet is just faster, and the burden that processor is caused is also just larger.Thereby can form the situation that packet blocks, the phenomenons such as integrated circuit board also can appear connecting in the control desk of base station.
In order to adapt to the demand of external field environment, must accomplish the enough flexible configuration of integrated circuit board groove potential energy, this just may produce loop in Ethernet link.For this reason, the application has proposed the method and apparatus that a kind of Ethernet link storm detects and suppresses, and detects and suppress the generation of storm by exchange chip; When detecting storm, cut off the Ethernet link that produces storm, open-loop, make broadcast packet in Ethernet link, circulate, remove simultaneously the address resolution logic list item (Address Resolution Logic, ARL) that self study is arrived, allow exchange chip relearn the MAC Address of clean culture, and with the port static binding of telecommunication network processor and exchange chip, guarantee when storm occurring, can control exchange chip in the Telnet base station; The Ethernet link of cutting off before after storm disappears, being communicated with again.Can reduce broadcast storm to the impact of base station by this mechanism, not hinder again the transmission of business datum simultaneously.
Introduce in detail a kind of Ethernet link storm detection of the application's proposition and the method and apparatus that suppresses below by enumerating several specific embodiments.
Embodiment one, introduces in detail a kind of Ethernet link storm detection of the application's proposition and the method that suppresses.
With reference to Fig. 1, show the method flow diagram that the embodiment of the present application one described a kind of Ethernet link storm detects and suppresses.
Speed when the forwarding rate of packet is higher than transmission regular traffic data far away in the Ethernet link during broadcast storm, so can be according to the maximum bandwidth of respectively transmitting port in the exchange chip, transmit port to each the forwarding rate threshold value is set, guarantee respectively to transmit the forwarding rate of port under regular traffic and can not reach the forwarding rate threshold value.
For example, the maximum bandwidth of transmitting port A is 1000Mbps, and the maximum bandwidth of transmitting port B is 100Mbps, and it is 500Mbps that the forwarding rate threshold value of transmitting port A can be set, and it is 50Mbps that the forwarding rate threshold value of transmitting port B is set.
In Ethernet link, constantly detect the forwarding rate of respectively transmitting port.
Can detect the forwarding rate of respectively transmitting port by third-party rate detection instrument or application program.
For example, detecting the forwarding rate of transmitting port A is 50Mbps; Detecting the forwarding rate of transmitting port B is 50Mbps.
When in step 12, detect respectively transmitted the forwarding rate of port after, described forwarding rate is compared with the forwarding rate threshold value of corresponding forwarding port, judge that described forwarding rate is whether more than or equal to the forwarding rate threshold value of correspondence forwarding port.
The forwarding rate 50Mbps of the forwarding port A that detects is compared with the forwarding rate threshold value 500Mbps that transmits port A, judge that the forwarding rate of transmitting port A is not greater than or equal to, namely less than the forwarding rate threshold value of transmitting port A.
The forwarding rate 50Mbps of the forwarding port B that detects is compared with the forwarding rate threshold value 50Mbps that transmits port B, judge that the forwarding rate of transmitting port B equals to transmit the forwarding rate threshold value of port B.
In a single day each forwarding rate of transmitting port reaches the corresponding forwarding rate threshold value of transmitting port, the forwarding rate of namely respectively transmitting port is greater than or equal to the corresponding forwarding rate threshold value of transmitting port, illustrate that abnormal conditions have appearred in Ethernet link in the base station, produced broadcast storm.
In step 13, judge that the forwarding rate of transmitting port A less than the forwarding rate threshold value of transmitting port A, illustrates not produce broadcast storm in the Ethernet link, do not close and transmit port A.
In step 13, judge that the forwarding rate of transmitting port B equals to transmit the forwarding rate threshold value of port B, illustrate to produce broadcast storm in the Ethernet link, then close and transmit port B, suppress the broadcast storm that produces.
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 the forwarding rate threshold value of each port of exchange chip is set, when the forwarding rate of port during more than or equal to the forwarding rate threshold value, close this port, cut off redundant link; Suppress storm by the dynamic cut-out to Ethernet link, so that the configuration of Ethernet link is more flexible, can close certain bar Ethernet link according to the concrete condition of base station, better meet the demand of practical application.
Embodiment two, introduce in detail a kind of Ethernet link storm detection of the application's proposition and the method that suppresses.
With reference to Fig. 2, show the method flow diagram that the embodiment of the present application two described a kind of Ethernet link storms detect and suppress.
According to the maximum bandwidth of respectively transmitting port in the exchange chip, transmit port to each the forwarding rate threshold value is set, guarantee respectively to transmit the forwarding rate of port under regular traffic and can not reach the forwarding rate threshold value.
The forwarding rate threshold value of respectively transmitting port in the exchange chip is set transmits 1/2nd of port maximum bandwidth for each.
Because the Ethernet link package forward speed during broadcast storm approaches the maximum bandwidth of transmitting port, respectively transmit the forwarding peak speed of port when the real work in conjunction with the base station, each forwarding rate thresholding of transmitting port is set to 1/2nd of the corresponding maximum bandwidth of transmitting port.So both guaranteed the transfer of data of regular traffic, and guaranteed again in time to detect broadcast storm.
For example, the maximum bandwidth of transmitting port A is 1000Mbps, and it is 500Mbps that the forwarding rate threshold value of transmitting port A can be set; The maximum bandwidth of transmitting port B is 100Mbps, and it is 50Mbps that the forwarding rate threshold value of transmitting port B can be set.
Can detect the forwarding rate of respectively transmitting port by third-party rate detection instrument or application program; If exchange chip can detect the forwarding rate of respectively transmitting port automatically, then can directly from exchange chip, read out the forwarding rate of respectively transmitting port.
For example, detecting forwarding port A is 200Mbps at T1 forwarding rate constantly; Transmitting port B is 60Mbps at T2 forwarding rate constantly.
The forwarding rate of detected forwarding port A in the step 22 is compared with the forwarding rate threshold value of transmitting port A, judge whether the forwarding rate of transmitting port A is greater than or equal to the forwarding rate threshold value of transmitting port A.
The forwarding rate of detected forwarding port B in the step 22 is compared with the forwarding rate threshold value of transmitting port B, judge whether the forwarding rate of transmitting port B is greater than or equal to the forwarding rate threshold value of transmitting port B.
Transmit port A at the forwarding rate threshold value 500Mbps of T1 forwarding rate 200Mbps constantly less than forwarding port A;
Transmit port B at the forwarding rate threshold value 50Mbps of T2 forwarding rate 60Mbps constantly greater than forwarding port B.
Judge in the step 23 and transmit port B at the forwarding rate threshold value 50Mbps of T2 forwarding rate 60Mbps constantly greater than forwarding port B.
When the forwarding rate of transmitting port when transmitting the forwarding rate threshold value of port, will produce broadcast storm, if do not take measures to suppress broadcast storm, will ceaselessly to approach the speed forwarding data bag of transmitting the port maximum bandwidth, cause network blockage in the Ethernet link.
Fig. 3 is with wireshark(network package analysis software when occurring the Ethernet link storm in the base station) schematic diagram of crawl inside of base station ether bag.
By shown in Figure 3, when having broadcast storm in the Ethernet link, exchange chip can be transmitted broadcast data packet with the fastest forwarding rate, and the interval between two broadcast data packet approximately only has 10us; Owing to ceaselessly transmitting broadcast data packet with the fastest forwarding rate in the Ethernet link, cause base station control station to disconnect with the connection of integrated circuit board, the PC end obviously slack-off situation of the speed of service can occur owing to utilizing wireshark to grab a large amount of broadcast data packet simultaneously.
When judge to transmit in the step 23 port B at T2 forwarding rate 60Mbps constantly when transmitting the forwarding rate threshold value 50Mbps of port B, close and transmit port B.
The Ethernet link storm appears in Fig. 4 in the base station, and when the Ethernet link storm suppressed, with the schematic diagram of wireshark crawl inside of base station ether bag.
By shown in Figure 4, after detecting broadcast storm and broadcast storm suppressed, the broadcast data packet of transmitting with the fastest forwarding rate in Ethernet link can exchanged chip port be blocked also and is thrown away, thereby normal packet can be transmitted in Ethernet link.When broadcast storm occurring, only close the forwarding port that produces broadcast storm place Ethernet link, other forwarding ports that are in the regular traffic state still carry out the forwarding of normal data packet.
When forwarding port B closes more than or equal to its forwarding rate threshold value owing to its forwarding rate, still detect the forwarding rate of transmitting port B.
For example, detecting the forwarding rate of transmitting the T3 moment of port B after closing is 30Mbps; Forwarding rate in the T4 moment is 20Mbps.
Forwarding rate and its forwarding rate threshold value of the forwarding port B that detects in the step 25 are compared, judge that whether the forwarding rate of transmitting port B is less than its forwarding rate threshold value.
Transmit port B at T3 forwarding rate 30Mbps constantly less than its forwarding rate threshold value 50Mbps; Transmit port B at T4 forwarding rate 20Mbps constantly less than its forwarding rate threshold value 50Mbps.
When the forwarding rate of transmitting port B during less than its forwarding rate threshold value, open and transmit port B.
Just for as far as possible in broadcast storm by the forwarding port of closing before opening after suppressing fully, can work as described forwarding rate and during greater than the predefined time, open this forwarding port less than time of this forwarding port repeat speed threshold value.
For example, the predefined time is 10s, also can preset according to actual conditions other time.When transmit port B at T3 and the T4 forwarding rate between constantly all the time less than its forwarding rate threshold value, and T3 and T4 time period between constantly during greater than 10s, open and transmit port B.
Simultaneously, can the Telnet base station in order to adapt under the external field environment, the exchange chip in the integrated circuit board is carried out associative operation, especially when broadcast storm occurring, can orientation problem, adjust the software configuration, extract base station information etc.Static binding can be carried out in the network address of Telnet base station and the port of exchange chip.When being remotely logged into the base station, by the binding relationship of the network address and switching chip port, can directly carry out associative operation to exchange chip.

Judge that transmitting port A surpasses its forwarding rate threshold value 500Mbps at T6 forwarding rate 600Mbps constantly; Judge that transmitting port A does not surpass its forwarding rate threshold value 500Mbps at T7 forwarding rate 300Mbps constantly.
And when forwarding rate does not surpass its forwarding rate threshold value, continue to detect its next moment forwarding rate.
Step 34 if forwarding rate surpasses its forwarding rate threshold value, is closed this forwarding port;
Transmit port A and surpass its forwarding rate threshold value 500Mbps at T6 forwarding rate 600Mbps constantly, will transmit port A and close.
Step 35 is treated forwarding rate less than its forwarding rate threshold value, and keeps a period of time, reopens this forwarding port.
