Embodiment 1

[0048] The embodiment of the present invention separates the version download and activation process, and starts the activation task after the user ensures that the version file is downloaded normally. In the traditional network element version upgrade, the upgrade order is optimized according to the topology structure, and the remote end is upgraded in order, and the network management The server can schedule the version upgrade process of the network elements in real time. In the embodiment of the present invention, the network element upgrade method is implemented by the following modules. For the continuous relationship of each module, please refer to Figure 4 .

[0049] 1: M1 version management human-computer interaction module: This module is deployed on the network management client. This module provides a human-computer interaction interface. The user imports the version file to the M5 module, selects the network elements that need to be upgraded and sends them to th...

Embodiment 2

[0060] This embodiment is a specific embodiment of network element upgrade. In this example, the upgrade order of network element upgrade is determined by the network management server. The specific process is as follows Image 6 shown, including:

[0061] Step S602, the user configures parameters such as the upgrade task management list capacity of the network management server, the maximum concurrent number, etc. in the M1 module according to the software and hardware configuration resources of the network management server, and forwards these configured parameters to the M3 module; imports the version file in the M1 module, selects The network element that needs to be upgraded forwards the version information and the identifier of the network element to be upgraded to the M2 module, and starts the upgrade operation.

[0062] Step S604, the M2 module adopts the breadth-first sorting scheme (which can be weighted in combination with the bandwidth information of the link), sor...

Embodiment 3

[0067] In Embodiment 2, in S604, the upgrade sequence is optimized by the network management server automatically calculating the optimal upgrade sequence according to the network topology information. The difference between this embodiment and Embodiment 2 is that before upgrading the network element version, the user can The optimal upgrade sequence is formulated through file configuration, and the upgrade information is imported through the file. The information includes the upgrade sequence, and the upgrade is performed in accordance with the order specified in the file.

[0068] The specific process of this embodiment is as follows Figure 7 shown, including:

[0069] Step S702, the user configures parameters such as the upgrade task management list capacity of the network management server, the maximum concurrent number, etc. in the M1 module according to the software and hardware configuration resources of the network management server, and forwards these configured par...

Abstract

The invention discloses a method and a device for updating network elements. The method comprises performing upgrade version downloading on at least one designated network element needing updating; and activating the upgrade versions downloaded by the network elements after upgrade versions of the at least one network element are downloaded, and updating the network elements. By means of the method and the device for updating network elements, the problem of service interruption of far-end network elements with near-end networks as starting points caused by reboot operation in near-end network element updating in correlation techniques can be solved, and the network bandwidth is fully used.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network element upgrading method and device. Background technique [0002] In order to adapt to the current situation that operators have many and fast-changing requirements, equipment manufacturers have to frequently update network element software versions to meet new requirements. [0003] Regarding network element software version upgrades, the existing upgrade solution is to automatically restart and activate the version after downloading the version, that is, after the network element downloads the software version to be upgraded, it immediately restarts and activates. However, there is a big defect in this solution in the microwave transmission network: since the microwave equipment is connected through a wireless link, the restart of the near-end network element (NE) will cause the service interruption of all remote network elements starting from the NE. During the up...
