Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a system, and a storage medium for port migration.

Background

As more and more business applications are run on the network architecture, the continuous, efficient and safe operation of the network is guaranteed, which becomes a great challenge for the network administrator. Although the investment in network management is increasing, and careful deployment and configuration of strict security policies are made, the problems of the network still come up endlessly, such as port damage, board damage, port bottleneck, and the like.

When the network problem occurs, on the premise of not interrupting the service (if protection is provided, the service is guaranteed not to be interrupted), the service needs to be switched from the port a to the port B, so as to realize port migration.

In the prior art, when a port, a board, or a port bottleneck occurs in a network, a network operation and maintenance worker needs to perform one-by-one configuration of a destination port in modules of a network manager, such as port configuration, interface configuration, protocol configuration, and service configuration, to implement port migration. However, due to the fact that the data configured on the port is numerous, the port migration mode is large in workload, long in time consumption, high in configuration error probability and quite large in configuration omission, network smoothness is seriously affected, and user experience is affected. Meanwhile, the port migration method has extremely high requirements on skills of network operation and maintenance personnel, and the network operation and maintenance personnel need to deeply understand the modules and the dependency relationship among the modules.

Meanwhile, the technical requirement of network maintenance personnel is reduced, so that operators are helped to save the cost of human resources.

Based on the foregoing embodiment, a third embodiment of the present invention provides another method for port migration, and this embodiment takes User Network Interface (UNI) migration as an example, and details the present invention with reference to a specific scenario. It should be noted that, for convenience of description, the method flow of port migration is described by dividing into two parts, namely data processing and warehousing of the migration port and data downloading.

Referring to fig. 4, the method flow of data processing and storage includes:

s401, when a user selects a network element, the network management client starts a port migration function according to the operation of the user.

In practical applications, the starting of the port migration function includes: and triggering service and TNP automatic discovery, inquiring a port migration plan, and if an unfulfilled port migration plan exists, prompting a user to implement existing port migration and then select an original port and a target port for migration.

Specifically, when the user clicks the menu function, the user may be guided to trigger the service and TNP auto discovery. For example, when a User Network Interface (UNI) migrates, when the User selects NE1, the User can be guided to trigger the above actions by clicking the UNI port migration start function of the menu, then the network management client builds a port migration query message, issues a query command to query a port migration Plan from the database, and if an unfeasible port migration Plan1 exists, prompts the User to implement the existing port migration Plan1 first.

S402, when the user selects the original ports and the target ports to be migrated in batch, checking whether the original ports and the target ports of each pair of migration ports meet the migration condition, if so, executing a step S403, otherwise, forbidding the migration, and ending the process.

Specifically, the verification method is as follows:

checking whether the original port SPortN and the destination port DPortN in each pair of ports are the same type of ports, and if not, prompting a user that the port of the current pair does not meet the port migration condition and needs to reselect the port;

and if the DPortN is occupied by the service or the transfer relationship between the SPortN and the DPortN is looped or the end point has the service, the transfer is prohibited, and the service is prevented from being broken.

S403, the network management client obtains data of all network elements (i.e. related network elements) on the display path passing through the migration network element according to the migration network element, and sends the data of the related network elements to the network management server.

S404, the network management server locks the relevant network elements and returns the marks to the network management client.

In this embodiment, the network element NE1 obtains the data of the network elements, such as the network elements NE2, NE3, NE4, etc., where the display route that the network element NE1 passes through is located, and constructs the locking message R with the network element data and sends the locking message R to the network management server, and the network management server locks the relevant network elements according to the received network element data and returns the locking flag L to the client for storage.

S405, the network management client sends the related data of the migration port to the network management server;

s406, the network management server processes the received related data and returns a processing result to the network management client.

In practical application, the related data includes at least one of a migration port type, a port attribute, interface data, quality of service data, operation maintenance management data, two-layer and three-layer protocol data, service data, and protection relationship data of the migration port.

Specifically, according to different data sent from the network management client to the network management server, the network management server has different processing modes for the data, and the returned processing results are different. The method comprises the following steps:

1. and calculating switching action data.

In practical application, a network management client sends migration port type data to a network management server, and the network management server is divided into a logic port and a non-logic port according to the migration port SPortN type. And the logic port calculates to obtain switching action data according to the MC-LAG main/standby state. And the non-logic port calculates to obtain switching action data according to the MC-MSP and the information of whether the original port works or is a protection port. And returning the processing result to the client for storage.

2. Port attributes of the migration port are calculated.

The port attribute calculation strategy is that the network management client divides the port attributes into three types of directly-copied attributes (Attr 1), indirectly-copied attributes (Attr 2) and inter-port exclusive attributes (Attr 3). The attribute (Attr 2) which can not be directly copied is displayed in the form of a port attribute configuration interface, and is issued to the network management server after the user selects the attribute value.

The network management server synthesizes the attribute value of the target port according to the value (Attr 2) of the non-replicable attribute issued by the network management client, the attribute (Attr 1) which can be directly copied and all the attribute values of the original port, synthesizes the modified attribute value of the original port according to all the attribute values of the original port and the exclusive attribute (Attr 3) between the ports, and returns the attribute value calculated by the original port and the target port to the client for storage.

3. Calculating the interface data of the migration port.

The interface information calculation strategy is that a network management client side issues a network management server of a migration port, the network management server comprehensively obtains an interface of a target port according to the non-duplicable attribute, the duplicable attribute and an interface value of an original port, and comprehensively obtains a modified value of the original interface according to the exclusive attribute and the interface value of the original port. And returning the processing result to the client for storage.

Specifically, the Network management client sends interface data of the migration port to the Network management server, and the Network management server obtains a VLAN interface value, a three-layer interface value and a three-layer sub-interface value of the destination port DPortN by synthesizing the non-replicatable attribute (Attr 2), the replicatable attribute (Attr 1) and a Virtual Local Area Network (VLAN) interface value, a three-layer interface value and a three-layer sub-interface value of the source port sport n, and obtains a VLAN interface value, a three-layer interface value and a three-layer sub-interface value of the source port sport n after modification by synthesizing the exclusive attribute (Attr 3) and the VLAN interface value, the three-layer interface value and the three-layer sub-interface value of the source port sport n. And returning the processing result to the client for storage.

4. Quality of Service (QoS) data of the migration port is calculated.

The QoS calculation includes eight parts of port Access List (ACL), port domain, flow queue, port speed limit, port shaping, port storm suppression, port Access Control (CAC), and port Per-Hop Behavior remapping (Per Hop Behavior, PHB).

The calculation strategy is that a network management client sends QoS data of a migration port to a network management server, after the network management server obtains the QoS data of the migration port, the QoS data of a target port (including port ACL, port domain, flow queue, port speed limit, port shaping, port storm suppression, port CAC and port PHB remapping data of DPortN) is deleted, and then the QoS data of an original port (including ACL, port domain, flow queue, port speed limit, port shaping, port storm suppression, port CAC and port PHB remapping data) is configured to the target port. And returning the processing result to the client for storage.

5. Operation Administration and Maintenance management (OAM) data of the migration port is calculated.

The OAM calculation includes three parts of Maintenance End Point (MEP), maintenance Intermediate Point (MIP), and last Mile Ethernet (EFM). The calculation strategy is that a network management client sends a network management server of a migration port, the network management server obtains OAM data of the migration port, modifies related ports of MEP, MIP and EFM, and replaces an original port with a target port. And returning the processing result to the client for storage.

6. And calculating protocol data of two layers and three layers of the migration port.

The two-three layer protocol calculation comprises ten parts of calculation of PIM-DM protocol, PIM-SM protocol, IGMP, spanning tree protocol, LDP, RSVP-TE, ISIS protocol, OSPF protocol, DHCP and VRRP.

The calculation strategy is that the network management client side issues two-layer and three-layer protocol data and interface calculation data of the migration port to the network management server, the network management server obtains the two-layer and three-layer protocol data of the migration port, modifies the associated port and the interface in the protocol, replaces the original port with the target port, and replaces the original interface with the target interface. And returning the processing result to the client for storage.

Specifically, the network Management server obtains a Dense Mode Independent Multicast Protocol (PIM-DM) of the migration source port spirtn, a Sparse Mode Independent Multicast Protocol (PIM-SM), an Internet Group Management Protocol (IGMP), a spanning tree Protocol, a Label Distribution Protocol (LDP), a Resource ReSerVation Protocol (Resource ReSerVation Protocol-Traffic Engineering) based on Traffic Engineering extension, RSVP-TE), intermediate system to Intermediate system Protocol (ISIS), OSPF Protocol, dynamic Host Configuration Protocol (DHCP), virtual Router Redundancy Protocol (VRRP), etc., modifying associated ports and interfaces in PIM-DM Protocol, PIM-SM Protocol, IGMP, spanning tree Protocol, LDP, RSVP-TE, ISIS Protocol, OSPF Protocol, DHCP, VRRP, replacing original port SPortN with destination port DPortN, and replacing the interface of original port SPortN with the interface of destination port DPortN. And returning the processing result to the client for storage.

7. And calculating the service data of the migration port.

The calculation strategy is to inquire the service related to the original port, present the inquired service on the interface, select the migration service by the user, then configure all the selected services on the destination port, the service calculation ensures the validity and consistency of the service, if the destination port does not satisfy the service logic, the migration is stopped.

8. And calculating the protection relation data of the migration port.

The calculation strategy is that the network management client side issues the migration port to the network management server, the network management server obtains the protection relation data of the migration port, modifies the associated port in the protection, and replaces the original port with the target port. And returning the processing result to the client for storage.

In practical applications, the step S406 may be performed by a processing module of the network management server, and the calculation steps of the above data may be respectively implemented by calculation sub-modules of the processing module.

S407, the network management client classifies the relevant network elements according to the uploading and downloading modes of the relevant network elements, and sends the classifications of the relevant network elements to the network management server;
