For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
The present invention is the circuit distributing method in a kind of resource management system, main thought is as follows: by the configuration of the condenser circuit (Bearer) that carries out in advance, when receiving client's business, set up transmission circuit according to pre-configured condenser circuit and circuit resource for the client, transmit data for the client thereon then; When the client cancels business, the transmission circuit of setting up is deleted.Wherein, condenser circuit is meant one group of Service Circuit, can comprise circuit and other condenser circuit.
As shown in Figure 2, be the flow chart of the circuit distributing method of the specific embodiment of the invention, its concrete steps are as follows:
Condenser circuit comprises attribute: source, Su Duandian, and capacity, route, state and protected mode etc., wherein capacity can be the ITU-T capacity of standard, also can be to divide off-gauge capacity that is defined as by time slot; Route, i.e. the routing information of this condenser circuit, when setting up condenser circuit, choosing of route can be for manually choosing, also can be for choosing automatically by system configuration; State comprises activated state and deactivated state, is used for showing whether current condenser circuit is used; Protected mode can not have, and can be 1: 1 protected mode or 1+1 protection pattern yet.
Wherein, protected mode was come transport service for using two operating circuits with same other attributes in 1: 1; but two operating circuit has active and standby branch; the high main business of main operating circuit transmission priority; the standby business that standby operating circuit transmission priority is low; when main operating circuit breaks down, abandon standby business, on standby operating circuit, transmit main business.The 1+1 protection pattern is " concurrent choosing receipts ", promptly uses two identical business of operating circuits transmission with same other attributes simultaneously, at receiving terminal, selects that transmission signals receives preferably in two operating circuits.
Condenser circuit can be crossed over polytype network, comprises SDH, PDH and DWDM.In the SDH network, if between two SDH ports, created an optical fiber, then it is created condenser circuit, and the division by frame structure and time slot, further create the condenser circuit of some low capacities; In the PDH network, the PDH passage is created into condenser circuit; In addition, can also cross over different network types, create condenser circuit according to demand to business.For example, need between A end and C end, create a condenser circuit, because process B between A end and the C end, wherein, A is the SDH type to the network between the B, and B is the PDH type to the network between the C, then arrive B at A, B selects suitable SDH port and PDH passage respectively to C, and distribution configuration command is finished and created a condenser circuit then.
Condenser circuit is divided into senior condenser circuit and rudimentary condenser circuit by measure, and senior condenser circuit can comprise several rudimentary condenser circuits, but the capacity that is included in the rudimentary condenser circuit in the senior condenser circuit can not surpass this senior condenser circuit.Senior condenser circuit can as a SDH optical fiber, also can be the condenser circuit that many combination of circuits constitute larger capacity for an existing circuit.
When level circuit is an existing circuit, divide by time slot, it can be divided into some low level circuitry.For example, the circuit of a 2M can be divided by time slot, forms the circuit of 32 64K, divides timing at circuit like this, can be that least unit is carried out capacity allocation with 64K.

If source, place terminal point information for customer requirement, the condenser circuit that has not configured, but, have with work order in source, the condenser circuit that the place terminal point information is partly mated, then select part to mate the condenser circuit of above-mentioned information, then it is combined with other circuit or other condenser circuits, be configured to satisfy the operating circuit of work order requirement, and issue configuration information to implementing webmaster department, carry out the configuration of real network by implementing webmaster department by configuration information, set up operating circuit.For example, customer requirement be A to C, A can realize to B to C by A to the connection of C, and had condenser circuit between A and the B, then only needs to select B to the path between the C, and itself and condenser circuit connected gets final product.
If information for the work order requirement, there is not condenser circuit with its coupling, then select suitable circuit, be configured to satisfy the operating circuit of work order requirement, and issue configuration information to implementing webmaster department, carry out the configuration of real network by implementing webmaster department by configuration information, set up operating circuit.
In this step, for the condenser circuit of customer selecting should be a deactivated state, the condenser circuit that is in deactivated state can be divided by time slot at any time, set up the condenser circuit of a low capacity therein.
In this step, also should carry out the selection of condenser circuit to the flow direction of business according to the client, if the flow direction of customer requirement is unidirectional, then for the condenser circuit of its selection also is unidirectional, and direction is identical; If the flow direction of customer requirement is two-way, then for the condenser circuit of its selection also is two-way, comprise two independently condenser circuits in the two-way condenser circuit, two independently the condenser circuit direction is opposite, thereby realizes two-way services.
In this step, between the condenser circuit and the protected mode between condenser circuit and the circuit need the coupling, matching principle comprises:
Protected mode is that 1: 1 rudimentary condenser circuit can be to create in the senior condenser circuit of 1: 1 or 1+1 or the circuit in protected mode;
Protected mode is that the rudimentary condenser circuit of 1+1 can be to create in the senior condenser circuit of 1+1 or the circuit in protected mode, needs the condenser circuit of markers work and the condenser circuit of protection simultaneously;
Do not have protected mode rudimentary condenser circuit can any protected mode do not have the senior condenser circuit of protected mode or circuit in create, and the condenser circuit or the circuit that are included under the rudimentary condenser circuit that does not have protected mode all do not have protected mode.
Owing to comprised the information of condenser circuit in the circuit information of storing in the database, when carrying out circuit arrangement, preferentially selected condenser circuit; And, no longer need to carry out site operation, so solved the time of this step greatly because condenser circuit is the circuit of having set up.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being made within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
