Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Fig. 2 shows the flow chart according to the binding chain circuit state dynamic adjusting method of the embodiment of the invention, and it may further comprise the steps:
Step S10 continues the transmission quality state of the Member Link of monitoring bundle link, and the state of Member Link is set in view of the above; And
Step S20 is provided with the state of bundle link according to the state of Member Link.
As can be seen, by technique scheme, realized adjusting the state of bundle link according to the transmission quality state of Member Link.
Continue monitoring Member Link transmission quality state and its operating state is set in view of the above, FCS that can be by paying close attention to message transmission (Frame CheckSum, frame check and) frame check mistake realizes.
Obviously, monitor the link transmission quality state by the FCS frame check mistake of paying close attention to message transmission, the Member Link transmission quality status monitoring that not only can be used for bundle link can also be applied to other links of non-bundle link, such as common single-core fiber link etc.
According to the embodiment of the invention, a kind of Link State dynamic adjusting method is provided, may further comprise the steps: monitor the FCS of link transmission message, and the state of link is set in view of the above.
In the prior art, some transmission link error rate is higher (for example, microwave link is influenced by weather etc. can produce higher bit error rate), and these mistakes (for example not necessarily can be reflected on the Interface status of the network equipment, may not produce transmitting warning or be not enough to influence the survival inspection of link layer protocol), but the user data that these mistakes may cause transmitting can not use, to user data very big infringement beyond doubt.Though can do certain improvement by raising survival inspection frequency to this, raising survival inspection frequency just means will consume the more bandwidth resource, and this expense concerning low speed chain circuit is too big.By monitoring FCS, the corresponding state of link can be set according to the transmission quality of link, be convenient in time flow be sent from backup link, reduce and avoid user's transmission quality to descend.
Monitoring FCS specific implementation process is described below:
(1) mistake bag detection time that Member Link is set t at interval, patient maximum FCS Packet Error Rate A (threshold value A, surpass this threshold value and think that link is unavailable), the FCS Packet Error Rate B that link-recovery can be used (threshold value B, link Packet Error Rate be lower than this threshold value think link-recovery can with) and the FCS Packet Error Rate whether link with Link State.
(2) suppose certain constantly certain Member Link on network equipment R1 at t 0Shi Keyou N 0The bag of individual fcs error, the bag number of fcs error is N behind the elapsed time t t, then interior during this period of time mean F CS error rate is: E t=(N t-N 0)/t;
(3) if E t>=A and disposed link linkage, this Member Link then is set is non operating state (promptly unavailable) and send network management information (if there is not the configuration link interlock, only send network management information), it is unavailable that Member Link is set, for PPP, can interrupt PPP and connect, and behind certain hour, initiate heavily to consult.
(4) behind the Link State on this equipment of setting, in time pass through the variation of message or alarm information noticing opposite equip. Link State, for PPP, (X is configurable can to send X Terminate (termination) message continuously, opposite equip. can detect the Member Link fault according to Packet Error Rate when fcs error was dropped if its value needs to guarantee Terminate message, if receive the negotiation packet again of opposite end then stop to send the Terminate message during sending the Terminate message).
(5) after this Member Link is consulted success again, send M detection messages (M is configurable) fast and detect link transmission quality (for PPP, can send the Echo-Request message, opposite equip. can be responded Echo-Reply, can reach the effect of two-way detection like this), (t ' configurable and t '>=t) determine according to corresponding transmission Packet Error Rate whether this link becomes are available: if Packet Error Rate E<=B after waiting for t ' time, then link-recovery can be used, otherwise interrupts this link and consult again.
Preferably, step S20 is provided with the threshold value that member's Link State exerts an influence to binding chain circuit state to bundle link, and the state of bundle link is set according to the state of Member Link.Specific implementation process is described below:
Bundle link such as MP are provided with two threshold values: minimum active members is counted C, maximum fault number of members D, when disabled Member Link number in the bundle link>=D, whole bundle link (is for example done unavailable processing, state that can bundle link is set to DOWN), when available member's number of links order in the bundle link of down state>=C, bundle link recovers available (the Member Link state can be provided with the method in (1) here, also can be to be provided with such as physical alert, survival inspection with prior art).
Obviously, the above embodiments can be provided with the corresponding state of link according to the transmission quality of link, are convenient in time flow be sent from backup link, reduce and avoid user's transmission quality to descend; The above embodiments can also be provided with the state of MP link according to the state of MP bundle link Member Link, are convenient in time not send flow, reduce and avoid user's transmission quality to descend from backup link when whole M P bundle link transmission bandwidth/quality does not meet the demands.
