A device upgrade method

Abstract

The invention provides a device upgrading method. The method comprises: step one, utilizing a BCMP protocol to dynamically assign an IP (internet protocol) address to each device accessed a network, and collecting the network physical location information of the devices; and step two, utilizing an SNMP message to obtain current software version numbers of the devices and upgrading the devices to be upgraded. The device upgrading method is based on the BCMP, the FTP and the SNMP to upgrade software versions of the devices in a cluster. The BCMP is used for assigning and managing the IP addresses and collecting device topological information; the FTP is utilized for providing the downloading of upgrade files; and the SNMP is used for giving upgrade parameters and upgrade instructions, so that rapid and simple IP address assignment and management and device upgrading implementation of the devices accessed the network can be achieved. Devices in abnormal conditions in the upgrading process can be rapidly positioned through the device physical topological information to help technicians to check problems during the upgrading process, so that the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of triple-network fusion communication, and relates to an equipment upgrading method. Background technique [0002] EOC (Ethernet over Coax, Ethernet data transmission through coaxial cable) is one of the most popular technologies in the current two-way network transformation, that is, to transmit Ethernet data signals in coaxial cables. For data transmission in the cable, its frequency does not occupy the cable TV frequency band, and coexists with the cable TV frequency. It has become the darling of the two-way network transformation technology due to its simplicity, stability, safety, and low cost. [0003] With the continuous advancement of science and technology, the scale of network development is getting larger and larger, and more and more devices are connected to the network. During the operation and maintenance of access network devices, EOC devices may have multiple different software versions at ...

AI Technical Summary

Problems solved by technology

[0005] 1. The IP address assigned by the DHCP protocol to the EOC device cannot guarantee physical continuity, and the EOC device cannot be divided into several subnet management domains according to the physical topology and location information, and an independent IP address segment is assigned to each management domain. Therefore, it is inconvenient to manage and upgrade equipment in a certain area

[0006] 2. If an abnormal EOC device is found during the upgrade process, the upgrade personnel can only check one by one according to the MAC address of the upgraded EOC device to find the abnormal device, and cannot quickly locate the physical location of the abnormal EOC device

[0007] 3. The management IP address assigned by PON+EOC access network equipment is usually fixed, and there is no lease period restriction and the need to obtain an IP address again

However, the DHCP protocol needs to bind the fixed IP address with the MAC address, which needs to be configured separately for each device, and the operation is more complicated; the DHCP protocol has the concept of a lease period, and the assigned IP address needs to be reassigned after the lease period expires.
