Embodiment
Be described in further detail implementing the present invention below in conjunction with accompanying drawing:
Fig. 1 is a simple system group network schematic diagram.Node A and Node B are represented two data access units respectively, and always total between the two M+N bar E1 link links to each other, and wherein the M bar is the circuit of actual use, and the N bar is an extension wire.
Fig. 2 has described the step of line resource management.
Step 1 is carried out static programming to line resource, and starts the resource use;
Main consideration is come into operation and alternative two kinds of circuit purposes.Circuit to plan is come into operation divides into groups according to the actual requirements again.Because circuit is used to carry out broadband data transmission, data mode is an ATM cell, abides by new IMA (the Inverse Multiplexing for ATM) consensus standard of releasing of atm forum, and circuit is carried out preliminary grouping.
Step 2 is done Dynamic Programming to line resource
Line resource in using is rethought distribution, and possible purpose has two kinds: a kind of is active mode, promptly does suitably on lane assignment according to the traffic requirement of business datum and adjusts; A kind of is passive mode, uses when disconnected in the line, and this is a kind of emergency measures of reducing the loss.
The step 3 local network management is assigned the webmaster order;
The webmaster personnel issue an order according to the actual requirements, require to give assigned I MA group to increase a circuit, perhaps reduce by a circuit from assigned I MA group.The reason of issuing orders may be that the bandwidth that the data traffic rising causes originally distributing to certain IMA group can not continue to satisfy the demands, or resource redundancy appears in utilized bandwidth that data traffic decline causes originally distributing to certain IMA group now.When the circuit that is coming into operation unavailable for a certain reason, when can't recover rapidly again in the short time, in order business not to be caused excessive influence, minimization of loss, the webmaster personnel also can issue an order, and reinstate alternative circuit, are increased in the IMA group of generation problem to go temporarily.After the problem for the treatment of solves, recover original use configuring condition again.All be that remote operation is carried out as this step 1.
The step 4 resource management module is analyzed the webmaster order
Resource management module is received the webmaster order, at first distinguishes command type, sends the dynamic management request to far-end then, whether supports this resource management mode to determine opposite equip..The transmission of solicited message can be by network management system, also can be other reliably communication modes rapidly.If in preset time, received the support response of remote equipment, so next further analyze order, whether need to confirm pre-negotiation.If newly-increased circuit must be consulted in advance.If reduce by a circuit, must finish link analysis earlier.
Does the step 5 judgement add chain? still delete chain?
If step 6 adds chain, then add the pre-negotiation of chain, and implement to add the order of chain webmaster
The pre-negotiations process that increases link is as follows:
The negotiations process of IMA group itself, the IMA group state machine that has comprised the circuit two ends is unavailable from using, and returns to the process of upstate then again, though the needed time of this process is very short, the influence of business is more or less all existed.The operation that increases link must cause the negotiations process of an IMA group.The purpose of consulting is to confirm the availability of extension wire not disturbing under the professional situation in advance, guarantee for the order of successful implementation webmaster provides to greatest extent, thereby it is minimum to order enforcement to drop to the harmful effect that business is brought.
The circuit coupling is initiated by near-end, carries out successively at an extension wire.If circuit can be used, write down this line number, the match is successful, finishes pre-negotiations process.If circuit is unavailable, turns to and investigate next bar circuit, until having investigated all extension wires.
Fig. 3 is the state diagram signal that system adds the chain operation, and a circuit matching process of initiating with near-end A is an example, is described in detail:

4) IMA group in two ends begins to consult.
5) if consult successfully, to step 8).If the merit of failing to consultations, remote equipment are deleted interim IMA group, and order is selected next bar from the extension wire set, creates interim IMA group once more, gets back to step 4).If remote equipment has traveled through all extension wires, still not success, it fails to match for this secondary line, to step 6).
6) remote equipment sends to near-end that it fails to match replys.Interim IMA group is separately deleted at two ends respectively.
7) proximal device order from the extension wire set is selected next bar, gets back to step 1).If proximal device has traveled through all extension wires, still not success, then pre-negotiation failure, near-end notice local network management does not allow to increase link.
8) the match is successful for this secondary line, and remote equipment is write down the extension wire number of current use, sends to near-end that the match is successful replys.Proximal device is also write down the line number that this coupling is used.Interim IMA group is separately deleted at two ends respectively.
9) proximal device notice local network management allows to increase link, and reports this secondary line near-end that the match is successful uses, distal line number.Continue step 6.
It is as follows that enforcement adds the command operation of chain webmaster:
The A proximal device sends formal interpolation LINK request to far-end.Solicited message comprises: the group number and the IMA that formally add request flag, alternative line number, assigned I MA group are set up upright parameter.
The B proximal device adds the pre-circuit of consulting to obtain in the assigned I MA group to.
The C far-end is received request, extracts solicited message, and the selected circuit in front is added in the assigned I MA group.
D two ends IMA organizes negotiation.
E consults successfully, to local network management report command execution results, comprises the number of links of current configuration, the actual number of links that activates.
If step 7 is deleted chain, then delete chain link analysis process, and implement to delete the order of chain webmaster
The operation of deletion link can cause the negotiations process of an IMA group too.The purpose of link analysis is not disturb under the situation of regular traffic as far as possible, knows a link in the current use at the line number of two ends correspondence, thus will order implement to drop to the harmful effect that business is brought minimum.
Circuit analysis is initiated by near-end, and the current use circuit of organizing at an IMA carries out.
Fig. 4 is the state diagram signal that system deletes the chain operation, and a circuit analytic process of initiating with near-end A is an example, is described in detail:
1) proximal device is given far-end transmitting line analysis request information.Analysis request information comprises: circuit analysis request flag, current line number to be analyzed, the IMA group at this circuit place.
2) proximal device is the selected circuit confinement of analyzing.
3) far-end is received analysis request, extracts record request information.And the state of local IMA group analyzed.
4) if far-end is observed IMA group state to change (one of certain IMA group is used circuit to move to the confinement state by operating state), to step 6).If do not change, this circuit analysis failure of far-end notice near-end.Proximal device is removed the circuit confinement.
5) near-end order from the current use line set of assigned I MA group is selected next bar, gets back to step 1).If proximal device has traveled through all circuits in the set, still not success, then circuit analysis failure, near-end is removed the circuit confinement, and the notice local network management does not allow to carry out the deletion link operation.
6) far-end is noted the line number of the link that state transition takes place, and analyzes successful respond to the near-end transmitting line, reports the line number of this link at local terminal.
7) proximal device is removed the circuit confinement.Require far-end this link of being kept in detention simultaneously.
8) far-end this link of being kept in detention.
9) near-end is analyzed IMA group state, if find that this circuit is kept in detention, and then link analysis success.Near-end reports webmaster can carry out the deletion link operation.Continue step 7.
