Description

Setting method of full routing circuit

The invention relates to the circuit setting of the telecommunication network, in particular to the network management system, after the resource management system completes the circuit planning, setting the circuit full routing, and when the network management unit device fails to be set, the error condition can also be processed to further improve. The circuit is set to success rate.

In the process of circuit establishment in the traditional telecommunication network, the resource management system firstly performs circuit planning, selects all available network management unit devices, that is, circuit routes, and then performs setting work one by one according to the form of the operator. . In order to improve the setting efficiency and reduce human error, in recent years, the network management system has been used to set up the equipment.

In the medium and large-scale telecommunication network, when the user applies for the circuit, the resource management system will allocate resources to the circuit, such as available devices, interfaces, VLANs (Virtual LAN), COS (Class of Service), etc., that is, circuit routing information. Then, according to the planned circuit routing information, the network management system separately sets the automatic circuit opening for the network unit devices of different brand models.

However, the automatic circuit setting process will inevitably fail, and the network management system will feedback the setting failure error message to the operator, so that the operator can judge and correct according to the error message. For the network management system, it can only respond to the failure message, and it cannot automatically judge and process the device setting failure status.

When setting a single network unit device, when the setting error occurs, it is excessively dependent on the manual processing. Whether it is correcting the setting error or manually resetting the set device, the resource reallocation can be performed again, and the fully automatic setting cannot be achieved.

In view of the shortcomings derived from the above-mentioned conventional methods, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally successfully developed a method for setting up a full routing circuit, which can greatly improve the success rate of circuit setting. And reduce manpower and time.

The object of the present invention is to propose a fast automatic circuit setting method, which replaces the setting of a single network unit device by the existing network management system with the overall concept of the circuit, and clearly defines conditions such as setting completion, setting failure, requesting reallocation of resources, and the like, and combining the resource allocation system. The automatic circuit setting mechanism can be completed, which can greatly improve the circuit setting success rate and reduce the manpower and time of operation.

A method for setting a full routing circuit that achieves the above object is mainly to perform different processing on the circuit setting status, and to distinguish the execution result into a successful setting, a failure of a non-device problem, a resource has been occupied (re-planning), and a setting failure. (cannot be processed by the system), etc., and summarize the corresponding processing mechanism of the circuit setting state, including the reset processing mechanism, the circuit resource reallocation processing mechanism, and the device response setting failure processing mechanism, etc., so that the circuit planning needs to be re-executed. Quickly and automatically respond. In all kinds of error situations, the network management system can be fully automated, without human intervention.

Referring to FIG. 1 , an automatic routing architecture diagram of a full routing circuit for implementing a full routing circuit setting method of the present invention is shown, and a medium and large network management system is displayed. There are several necessary components: network unit device 3, resource management and control. System 1, network management system 2 and operator 4. The resource management system 1 manages network resources, retains the available state and network topology of all current network components, and performs network resource assignment, that is, circuit routing information, when the user rents a circuit. Then, the network management system 2 performs setting and state extraction on the network unit device 3 according to the routing information allocated by the resource management system 1. The network unit device 3 may include an L2/L3 Switch, a Router, a VDSL/VDSL2, a PON, and the like.

In order to achieve automatic routing, the network management system should be set in full routing mode instead of the single device mode. The circuit routing setting process is shown in Figure 2. The setting steps include:

(1) Obtaining circuit routing information and setting network unit equipment, and the resource management system obtains circuit routing information and setting parameters, such as available devices, interfaces, bandwidths, VLANs, COS, etc., for user circuit resource assignment; The allocation method is that the network management system obtains the full routing information of the circuit from the resource management system, and sets the equipment included in the routing. The setting method can adopt SNMP or Telnet, and execute setting instructions according to the model and characteristics of the equipment brand;

(2) Obtaining the network unit device setting state, the network management system must further process the circuit setting status, and the circuit setting status is summarized by the setting status of each device included in the circuit routing. The network management system determines the device setting status and confirms whether the setting item is successfully set. The setting status of the determining device may include:

(2a) Setting success: normal execution for circuit setup and setting;

(2b) Non-device problem barrier: An error occurred during the setup process, but the cause of the error is that the mediation network problem is not a device problem, such as the device unreachable, or the high packet loss rate (High Packet Loss Rate). Causing a slower response from the device;

(2c) The resource is occupied: the resource allocated by the device response resource management system has been occupied by other circuits, such as the VLAN or the interface has been used;

(2d) Command execution failure: When the network management system executes the circuit setting command, it finds that the setting fails, and cannot be solved and processed by the network management system, such as parameter setting failure.

In the process of confirming the setting failure, the network management system can determine that the error is an intermediary network error, a resource occupation error, or a device instruction execution failure.

(3) Inductive circuit setting state and processing mechanism. Since the circuit full routing setting has integral characteristics, the circuit setting state must be determined according to the state of all circuits including the device. The circuit setting state summarized by the above device state and its processing method are as follows:

(3a) The circuit setting is successful, confirming that all the devices included in the circuit routing are set, and the return circuit setting is completed;

(3b) Need to be reset. In the case of circuit setting (2b), the network management system will wait for a while before attempting to set the device. However, if the number of retry attempts has reached the upper limit of the number of re-sets, for example, the maximum number of retry attempts is three times, the setting cannot be completed. If it is determined that the device cannot be set, the same processing method as in case (3c) will be taken, and the occupied resources will be released and returned. Re-plan the circuit for the resource management system and notify the operator to investigate and deal with the problem of the intermediary network or equipment;

(3c) Circuit resource reallocation, in the case of circuit setting (2c) (2d), the occupied resources will be released and returned to the resource management system for circuit planning. Due to the complete circuit routing and setting information, the network management system will perform circuit removal setting for the set device, that is, perform circuit reverse installation to ensure that resources are not occupied;

(3d) The device response fails to be set. The device fails to be resolved by the network management system. The processing mode can be similar to the situation (3c). The network management system will release the occupied resources and return it to the resource management system. Conduct circuit planning and notify operators to investigate and deal with equipment problems.

(4) Further processing according to the circuit setting failure condition, when the resource management system receives the circuit re-planning request of the state (3b) (3d), the resource assignment of the problem device or interface will be avoided until the operator returns the repair completion. . And complete the routing circuit setting by process (1).

Since the circuit setting state is clearly defined, the network management system can perform error determination and processing when the network unit is set incorrectly, and the entire circuit setting failure will not be caused due to a single device or interface obstacle, and a fast automatic circuit setting can be achieved.

The method for setting a full routing circuit provided by the present invention has the following advantages when compared with other conventional technologies:

1. The method for setting the full-route automatic circuit proposed by the present invention has more circuit integrity than the conventional single-device angle setting, and automatically releases the occupied resources for the circuit that fails to be set.

2. The method for setting a full-route automatic circuit proposed by the present invention clearly defines a circuit setting state and an automatic processing method, and replaces an operator's processing mode excessively in place of a conventional device setting error, and aims to reduce the time of human operation in the circuit setting process.

3. The full routing automatic circuit setting method proposed by the invention can feed back the state to the resource management system when the device is wrong, so that the circuit is re-planned, and the circuit is established without being affected by device errors.

4. The full routing automatic circuit setting method proposed by the invention can greatly improve the success rate of the automatic setting circuit and shorten the time required for circuit setting.

The above description is intended to be illustrative of the preferred embodiments of the present invention, and is not intended to limit the scope of the present invention. range.
