Description

SDH network management method and client

Technical field

The present invention relates to the field of communications technologies, and in particular, to a Synchronous Digital Hierarchy (SDH) network management method and a client.

Background technique

At present, various protection structures are available on the network. The protected unit can be a single SDH multiplex section (such as linear multiplex section protection) or a part of the SDH end-to-end path (such as subnet connection). Protection), or the entire SDH end-to-end path. The physical implementation of these protections includes loops or linear node chains. Each protection topology is related to network nodes, switching conditions, protocols, and algorithm rules. At present, many device manufacturers have developed network devices suitable for different protection topologies. Therefore, in view of the ease of use of network management, in order to avoid the differences of these devices, a general protection switching setting operation and display method are designed. It seems very necessary.

In the traditional telecom network management software, for the protection switching setting of the user, the client cannot perform the detailed service restriction, but processes according to the information returned by the analysis server, and judges whether the current device supports the switching service from the information. If the device currently supports the switchover command, the service is delivered to the device; otherwise, the client prompts an error message. This method is relatively unintuitive, often leads to invalid operation of the user, and is easy to cause the network administrator to understand. For example, in the switching of the SDH two-fiber protection ring, the practice switching level is the lowest, followed by manual switching, forced switching, and blocking, etc., and the clearing switching level is the highest. If the user performs the forced switching command, the low-level switching commands such as practice or manual cannot be executed, but the traditional network management client software cannot handle the switching priority.

For the protection switching function of the traditional network management client software, the switching setting command cannot be executed in the protection switching status query interface. The switching status query operation cannot be performed in the protection switching setting interface. The two operation interfaces are independent and separate from each other. of. At the same time, the traditional network management client does not maintain the current switching command of the protection port. The user cannot directly learn the protection switching operation currently permitted by the device. Summary of the invention

The problem to be solved by the present invention is to provide an SDH network management method and a client to solve the problem that the protection switching of the existing SDH network management software is complicated, and the switching state and the switching command are not intuitive enough to be understood.

To solve the above problem, the present invention provides an SDH network management method, the method includes: when receiving a request for creating a protection group initiated by a user through a multiplex section configuration interface, the network management client provides a creation wizard for the user to set a protection group. a parameter, and after the user completes the parameter setting, sends a protection group command to the server, where the protection group command carries the relevant parameter of the protection group, and the relevant parameter of the protection group includes the protection group ID;

The server saves the related parameters of the protection group that are carried in the protection group command, and sends a notification to create a protection group broadcast notification to all clients that subscribe to the service, where the protection group broadcast notification carries the protection Group ID;

The client sends a query command to the server according to the protection group ID that is parsed from the created protection group broadcast notification.

Sending, by the server, the relevant parameters of the corresponding protection group to the client according to the protection group ID carried in the received query command;

After receiving the relevant parameters of the protection group, the client displays all relevant parameters in the same interface; and then, according to the protection group ID, issues a query command to query all protection relations in the protection group from the server. Switching state and maintenance state, and appearing in the interface;

Thereby implementing protection switching settings and display.

The related parameters of the protection group include: basic information of the protection group, protection attributes, protection parameters, protection relationships, and APS setting information. The protection group ID belongs to the protection group basic information, and the switching status and the maintenance status belong to the protection relationship.

The above method may also have the following features:

The step of the client displaying the related parameters of the protection group in the same interface includes: the client displays the basic information of the protection group in the main table, and the protection attribute, the protection parameter, the protection relationship, and the application support (Application) Support, APS) setting information is displayed separately Each sub-table is located in the same interface as the main table.

The above methods also include:

A switching command rule file is saved in the client, and the corresponding relationship between the device type, the protection group type, the protection unit type, the current switching command, and the executable switching command is defined in the switching command rule file;

When the user is selected to select a port as the switching operation object in the protection relationship sub-table, the client performs the following operations: According to the protection group type, protection unit type, maintenance status, and device type of the port, the file is searched for the switching command file. All the available switching commands are displayed and displayed to the user. After the user selects one of the available switching commands, the client sends a switching command to the server to set an operation message, and the switching command sets an operation message. Carry: the protection group ID, the protection group type, the operation port, and the switching command selected by the user;

After executing the switching command sent by the client, the server sends a switching command to the client to set a broadcast notification, where the switching command sets the device name, the protection group ID, the actual switching port of the device, and the corresponding maintenance state. ; as well as

The client parses the device name and the protection group ID from the received broadcast notification of the switch setting command. If it is determined that the resolved device name is the same as the client name, the server queries the server according to the protection group ID. The switching state, and refreshing the protection relationship sub-table according to the switching state data returned by the server.

The invention also provides a client, the client is set as:

When the request for creating a protection group initiated by the user through the multiplex section configuration interface is received, a creation wizard is provided for the user to set the relevant parameters of the protection group, and after the user completes the parameter setting, the user creates a protection group command, The protection group command carries the relevant parameters of the protection group, and the related parameters of the protection group include the protection group ID; and the server saves related parameters of the protection group carried in the creation protection group command;

BRIEF abstract

FIG. 1 is a flowchart of an SDH network management method according to an embodiment of the present invention.

Preferred embodiment of the invention

As shown in FIG. 1 , the SDH network protection switching setting and display method of the present invention includes: Step 1: When receiving a request for creating a protection group initiated by a user through a multiplex section configuration interface, the network management client provides a creation wizard for the user. Set the related parameters of the protection group, including: basic information of the protection group (including identification of the protection group (ID), protection attributes, protection parameters, protection relationship, and APS setting information. These data configuration items are existing network management. Basic information that needs to be configured. After the user completes the parameter setting, the client sends a protection group command to the server, which carries the above parameters.

Step 2: After receiving the command to create a protection group sent by the client, the server saves the parameters carried in the command, and then sends a notification to create a protection group broadcast to all clients that subscribe to the service, where the command includes Protection group ID;

Step 3: The client parses the received protection group broadcast notification, and sends a query command to the server according to the parsed protection group ID. Step 4: After receiving the query command, the server sends the relevant parameters of the corresponding protection group to the client according to the protection group ID carried in the server;

Step 5: After the client receives it, display all relevant parameters on the same interface. The protection group basic information is displayed in the main table, and the protection attribute, the protection parameter, the protection relationship, and the APS setting information are respectively displayed in each sub-table that is located on the same interface as the above-mentioned main table, and the protection relationship sub-list includes The protection relationship name, the protection unit type, the port information, the switch status, and the maintenance status (also called the switch command). The maintenance status refers to the current user's switch command, and the switch status refers to the corresponding port pair switch command. Response result;

Step 6: The client then queries the server to query the switching status and maintenance status of all protection relationships in the protection group according to the protection group ID, and then displays the information on the above interface. If the protection relationship is displayed by the sub-table, the switching state of each protection relationship is displayed in the protection relationship sub-list corresponding to the maintenance status.

After that, when the user selects a protection group in the primary table, in the following sub-tables, the protection information, protection parameters, protection relationship, and APS settings of the current protection group can be viewed, that is, only one interface can be used. Intuitively display complete information on all protection groups of the device.

When the user is informed that a port is selected as the switching operation object in the protection relationship sub-table, the client needs to perform the following operations:

1. Obtain related data of the operation object, including: protection group type, protection unit type, and switching command of the port (that is, maintenance status)

2. Using the above three data and the device type (the type of the node device currently operated by the user) to perform a matching search to the switching command rule file to retrieve all available switching commands and display them to the user;

The switch command rule file is pre-existing in the client, and its data structure is defined by the Extensible Markup Language (XML) specification. The nodes defined in the file are: device type, protection group type, protection unit type, current switching command, and executable switching command. The value range of the user-executable switching command depends on the values of the other four nodes. The file takes different values of the device type, protection group type, protection unit type, and current switching command. All possible scenarios are defined, and the values of valid executable swap commands are defined according to different scenarios. This file supports all devices and protection group types. This file can be used to easily upgrade software for network management services. This is different from other network management systems.

3. After the user selects one of the above-mentioned available switching commands, the client sends a switching command to the server to set an operation message, which carries: a protection group ID (to inform the server which protection group to switch, because one device There may be multiple protection groups), protection group types (different protection group types perform different switching protocol algorithms), operation ports, and user-selected switching commands;

After the server executes the switchover command sent by the client, the client sends a switchover command to set the broadcast notification, which carries the device name, the protection group ID, the actual switchover port of the device, and the corresponding switchover command. The event, the amount of reported information should not be too large, otherwise it will easily cause network congestion. The switching port reported here is the operation port object for the user to switch in the protection relationship;

5. The client parses the received broadcast setting command broadcast notification, and obtains the device name and the protection group ID from the packet. If the resolved device name is the same as the client name, the client uses the protection group ID as the protection group ID. Querying the unique condition of the protection group switching state to construct a query message. The device returns the switching status of all the ports in the protection group according to the protection group ID sent by the client. The slave server queries the switching status of the protection group (that is, The protection group's protection relationship is the switching state of all ports). Finally, the client refreshes the protection relationship interface according to the port switching status data returned by the server.

In summary, the design idea of the present invention is quite different from the traditional network management for setting the priority of the protection switching. The traditional network management client provides the user with a fixed set of switching commands. Regardless of the type of protection group, the user can configure any switching command for any port of the protection relationship, and then correct the error by executing the switching command. The user's operation, and the problem of switching priority cannot be handled. The present invention directly filters out the switching command that does not conform to the actual working service by using the switching command rule file, and enables the user to have a clearer understanding of the switching service setting operation that can be performed in the next step, thereby enhancing the ease of use of the network management.

In the protection relationship sub-list, the last two columns of data (switching state, maintenance state) of the protection relationship are fully integrated with the protection relationship, and the switching state and maintenance state of the protection relationship port can be directly seen, and the user operates the switching button. When you can clearly see the next available reversal Order. After the user selects a switching command to execute, the client can directly refresh the current switching state without switching any interface. The actual operation of the protection switching service after the switching can be seen without any additional actions. From the perspective of the ease of use of the network management system, the present invention greatly improves the ease of use of the network management protection switching service function.

The protection group includes a protection group index summary table and basic attributes (protection group ID, user label, protection group type, and the like), and the classification information of the currently selected protection group includes: a protection attribute table, a protection parameter table, a protection relationship table, APS setting table, etc. The last two columns in the protection relationship table are the Maintenance Status (Switching Command) column and the Switch Status column. If the user selects a row, it indicates that the port of the currently selected row is switched. The user can select an available switching command from the switching pull-down button. The available switching command is that the client switches from the data selected by the current user. The query is obtained from the rule file.

The protection relationship status (switching status and maintenance status) and the switching command setting display include: First, the user has created a protection group and navigated to the protection relationship sub-panel:

Step 1: Select a protection group in the primary table of the protection relationship status and the switch command settings display.

ID, all sub-tables (protection attributes, parameters, protection relationships, APS settings, etc.) will present the classification information of the protection group. When the user selects a row of data of the protection relationship sub-table as the operation object, the client obtains the switching command of the selected port, the protection group type, the protection unit type, and the current port, and then matches the data according to the current device type. The query is performed in the command file of the switch, and is displayed to the user after obtaining the legal switch command (for example, forced switching, manual switching, etc.);

Step 2: After the user selects the switching command to be performed, the client constructs a switching command to set the operation packet and sends the packet to the server. The packet carries the protection group ID, protection group type, operation port, and selected switching. Command

Step 3: After receiving the server, issue the switch setting command. Because it involves multiple client synchronization responses, it does not use the server response method, but broadcasts all the clients that subscribe to the current service.

Step 4: After the client receives the switch command issued by the server to set the broadcast notification, parse The notification message obtains the protection group ID, and the client starts to query the server for the protection status task of the ID (the server directly answers the query command), and parses the server response message (the response message includes: all the switching ports and The corresponding status information and the protection group ID) traverse each of the switching ports, and according to the protection group ID and the port information, construct a key (the protection group ID and the port value string are superimposed), and match a status data. Then form a mapping table to fill the memory container, and after the execution is completed, notify the protection relationship table interface to refresh;

Step 5: After receiving the refresh interface command, the protection relationship sub-panel traverses each row record in the table in the panel, and generates a keyword (protection group ID and port value according to the port value of each row and the currently selected protection group ID. String superposition), and then query the corresponding state information from the memory container mapping table according to the keyword, and finally refresh the interface.

The invention also provides a client, the client is set as:

And sending a query command to the server according to the protection group ID that is parsed from the creation of the protection group broadcast notification;

And receiving, by the server, a related parameter of the corresponding protection group, where the related parameter of the corresponding protection group is sent by the server according to the protection group ID carried in the received query command; and receiving the protection group After the parameter is displayed, all related parameters are displayed in the same interface. Then, according to the protection group ID, the query command is sent to query the switching state and maintenance state of all protection relationships in the protection group from the server, and in the interface. show out;

Thereby implementing protection switching settings and display.

The related parameters of the protection group include: protection group basic information, protection attributes, protection parameters, protection relationships, and APS setting information, etc., wherein the protection group ID belongs to the protection group basic information, and the switching The status and maintenance status are protected.

The client is also set to:

The device name and the protection group ID are parsed from the received broadcast notification of the switch setting command. If it is determined that the resolved device name is the same as the client name, the server is queried for the switching of the protection group according to the protection group ID. Status, and refresh the protection relationship sub-table according to the switching state data returned by the server.

It is a matter of course that the invention may be embodied in various other forms and modifications without departing from the spirit and scope of the invention.

Industrial applicability The method of the present invention adopts a general configuration technology, and reasonably integrates the basic configuration data (protection relationship name, port, protection unit type, APS usage byte, etc.) of the protection relationship with the port switching state and the port switching command. Together, it is displayed in a table, which provides a data environment for the protection switching setup. It is very intuitive, which not only facilitates the user to easily and clearly perform the switching setting operation, but also integrates well with the switching query operation. The exchange information can be clearly and intuitively expressed. This allows the staff to easily and clearly understand the working status of the current service port, especially in the case of complex network configuration, which helps the staff to quickly locate the problem on the same interface and improve the work efficiency to a certain extent.
