Description
Technical field
The present invention relates to Inverse Multiplexing over ATM (IMA, the Inverse Multiplexing for ATM) technology of the communications field, relate in particular to the processing method and the device of the unstable link of quality in a kind of IMA transmission.
Background technology
Asynchronous transfer mode (ATM; Asynchronous Transfer Mode) the inverse multiplexing technology is that atm cell stream is gathered; With cell is that basic inverse multiplexing transmits in a plurality of low speed physical links; The cell flow that transmits on again with a plurality of low speed physical links at far-end is reduced to initial cell flow set, thus bandwidth that can multiplexing easily a plurality of low speed physical links.The IMA technology is to support a kind of practical approach of high-speed atm cell flow, is suitable on physical interfaces such as E1 and T1, transmitting ATM cell, to make full use of existing low speed chain circuit, for ATM at a high speed uses the condition of having created.
The IMA technology comprises the multiplexing and demultiplexing of atm cell stream.It is the logical links of a high speed with many low speed physical link clusters that the IMA technology is used the mode of load sharing polling, and the speed of this logical links approaches each physical link speed sum.In agreement; One group of physical link crowd is called as the IMA group; Physical link in the IMA group is called as the IMA link, and the IMA link is divided into reception and sends two independent, direction the processing of data, and the IMA link of transmit leg and recipient's IMA link be opposite end (far-end) each other.As shown in Figure 1; IMA group A and IMA group B be the opposite end each other; All comprise link 0, link 1, link 2 and link 3, the reception (RX) of each link of the corresponding IMA group of transmission (TX) B of each link of IMA group A, the transmission (TX) of each link of the corresponding IMA group of reception (RX) B of each link of IMA group A.
Ima protocol regulation link has five kinds of states; Be respectively not (Not In Group), unavailable (Unusable), available (Usable), activation (Active) and obstruction (Blocking) in group; Wherein, the state that the expression link does not dispose in the IMA group in group; Unavailable expression link dispose in IMA group and finishes, still owing to fault or disabled (Inhibit) and out of use state; Available expression link is ready for operation, but is waiting for the state of opposite end notice; The reception link that blocks the expression state of activation is owing to disabled causing can't use; Under state of activation, link transmission is from the cell of ATM layer.Fig. 2 is the transmission link state machine sketch map of agreement regulation, and Fig. 3 is the receiving link status machine sketch map of ima protocol regulation, and the available and activation of link need decide with reference to the state of far-end link.
The prerequisite of ima protocol regulation IMA group in running order (Operational) is to have the link that is no less than preset threshold number to be in state of activation in the group.This thresholding is called as " minimum active link number "; Defaultly be set to one; So just can guarantee in the IMA group between the multilink redundancy backup function for fault; Promptly in IMA group only part of links failover or other reasons be in unactivated state, the IMA group still can be in running order and can cell transmitting-receiving service be provided to the ATM layer.
The IMA link is carried out Synchronous Processing through IMA Control Protocol (ICP, the IMA Control Protocol) cell in the periodic monitoring ima frame, successfully is synchronously that IMA receives the prerequisite that link gets into activation or available attitude.Fig. 4 is the synchronous state machine transition sketch map of ima frame; As shown in Figure 4, be in the link of synchronous regime (IMA Sync), if receive the icp cell that several are invalid or make mistakes continuously or lose icp cell; Can step-out get into trapped state (IMA Hunt); Therefore the receiving terminal link can break away from activated state, and informs the opposite end through the icp cell that other activation or available link send in the ima frame, makes the opposite end send link and also breaks away from activated state.Because the fault of IMA link is the keep-alive through icp cell to be detected and realizes; In the receiving terminal link failure occurs to the time period of transmitting terminal Link State deexcitation; Can the instantaneous atm layer cell that is transmitted that causes lose, this is the switch protecting expense during the part of links fault in that ima protocol allows, the IMA group.After the physical link fault recovery, the IMA link of local terminal and opposite end need according to agreement regulation through receiving terminal success synchronously, receive and with processing procedure such as transmitting terminal hand shaking Link State, could get into activated state once more.
If part physical link transmission quality is unstable in the IMA group; For example the error rate is fluctuated, the frequent sudden strain of a muscle of physical link broken; The state machine of then corresponding IMA link will overturn between activated state and non-activated state repeatedly; Damage that causes in the Link State handoff procedure (like instantaneous cell loss concealment) and the extra performance expense (the frequent negotiation of two ends IMA link state machine) that causes to system will continue to exist, and so, can increase the weight of the load of IMA system; Reduce the efficient of MA system, influence the service quality of IMA.

Embodiment one
In the present embodiment, the stability status machine has been introduced in the judgement and the processing of IMA link transmission quality stability.
As shown in Figure 6, the stability status machine comprises " initially ", " steady quality ", " quality is unstable " and " punishment forbidding " four kinds of judgement states.
Wherein, " initially " state gets into the IMA group for the IMA link is configured, and the link that is in " initially " state unconditional jump at once arrives " steady quality " state.
" steady quality " state is meant link overturns in the IMA group number of times less than preset upset thresholding between activated state and non-activated state in a last monitoring periods, or link current be in activated state and belong to IMA organize the inherence before minimum active link count the optimum link within the n.
" quality unstable " state is meant that the number of times that link overturns is not less than said upset thresholding between activated state and non-activated state in a last monitoring periods, and this link do not belong to IMA yet and organize the inherence before minimum active link count the optimum link within the n; Perhaps, the number of times that link overturns between activated state and non-activated state in a last monitoring periods is not less than said upset thresholding, and this link is current is in non-activated state.
After the link administer doses of punishment property deactivation operation of local terminal active to " quality is unstable " state; The state of this link will migrate to " punishment forbidding " state; Be in the link of this " punishment forbidding " state; Only overtime in punishment, local terminal just can get into " steady quality " state after initiatively removing the forbidding of said link once more.
Here, minimum active link count n be the IMA group of ima protocol regulation get into operating conditions the active link that must possess count lower limit.Influence the principle that current I MA organizes availability for guaranteeing when screening, must not observe with the unsettled link of disable transmission quality; Before minimum active link count the optimum link within the n; Even its upset number of times is not less than preset upset thresholding k, the state of this link also remains " steady quality ".
In the present embodiment; Begin from IMA group initial configuration; Be provided for controlling the cycle timer of monitoring periods; Periodically monitor the upset of state machine between activated state and non-activated state that IMA organizes interior each link through said cycle timer, when a monitoring periods expired, statistics obtaining the upset number of times of state machine between activated state and non-activated state of each link in the IMA group; And according to upset number of times from small to large the order of state machine between activated state and non-activated state of each link in the current monitoring periods; All links that are in activated state in the IMA group are carried out the quality ordering of transmission quality stability, and what the upset number of times was minimum be transmission quality stability optimum link, upset number of times maximum be the poorest link of transmission quality stability; Wherein, with rank preceding minimum active link count n link within the n confirm as said before minimum active link count the optimum link within the n.
In the present embodiment, also can join flexibly, but monitoring periods should be not less than link from unavailable attitude to activated state four times of the longest transit time, is recommended as 4 minutes for the setting of the monitoring periods of IMA link transmission quality stability; For upset thresholding k, recommending value is 1, promptly means and carries out strict examination: need only in 1 upset of monitoring period internal state existence, just assert to have the unsettled possibility of transmission quality.
As shown in Figure 7 for the handling process of each link in the IMA group (comprise and receive link and send link) when a monitoring periods finishes, comprise the steps:
Step 704 is updated to " steady quality " with the stability status machine of said link, and changes step 711 and handle.
Whether step 705 for there being the unstable possible link of transmission quality, further judges said link current states machine in activated state, if then change step 706, otherwise changes step 707.
Step 706, to the current link that is in activated state, judge said link whether belong to before minimum active link count the optimum link within the n, if then change step 709, otherwise change step 708.
Step 708 is updated to the stability status machine of said link " quality is unstable ", changes step 710 then.
Step 709 is updated to " steady quality " with the stability status machine of said link, changes step 711 then.
Step 711 is the link of " steady quality " to the stability status machine, and the continuous disabled number of times zero clearing with said link finishes current handling process.
In the present embodiment, also comprise in the step 710: when being expired by the punishment timer of punishment link, carry out following handling process, as shown in Figure 8, step comprises:
Step 802 is carried out releasing forbidding (Not Inhibiting) operation to the state machine of said link punishment link that timer is controlled, and the stability status machine of said link is updated to " steady quality ".
Step 803 is increased progressively 1 also preservation with the continuous of said link by the punishment number of times.
In the step 710 of present embodiment, will be with reference to three factors for the calculating of punitive forbidding duration: punishment duration lower limit, the punishment duration upper limit and current saved continuous by the punishment number of times.The punishment duration lower limit and the upper limit can be carried out flexible configuration as required, and generally speaking, punishment duration lower limit is defaulted as 2 minutes, and the punishment duration upper limit is defaulted as 4 hours.In the practical application; Punitive forbidding duration during for the first time by punishment is set to dispose lower limit; For being punished that repeatedly stability does not still have the link that improves continuously; Current punitive forbidding duration can and be calculated by the punishment number of times based on last punitive forbidding duration continuously, and the specific algorithm of calculating can be configured according to actual needs, for example; The specific algorithm that calculates may be selected to be: on the basis of last once punitive forbidding duration, with the relation of being punished that continuously the linear ratio of number of times increases progressively or exponent function relation increases progressively.
In the present embodiment, can fast and effeciently screen and limit the use of the unsettled link of transmission quality in the IMA group, reduce of the negative effect of the frequent local fault that takes place whole QoS.
The present invention also can have other various embodiments, and under the situation that does not deviate from spirit of the present invention and essence thereof, those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.
