The main network elements of the whole system comprise: OLT (Optical line terminal), ONU (Optical Network Unit), eoC office, eoC terminal.
In order to improve user experience, function addition and function optimization of the EoC terminal are required to be performed frequently, and continuous upgrading of the software version of the EoC terminal is inevitable. As shown in the PON + EoC network architecture diagram depicted in fig. 1, each OLT may have multiple ONUs connected downstream, each ONU may have multiple EoC central offices connected downstream, and multiple EoC terminals may be connected downstream below each EoC central office, where the number of terminals in such a network reaches 4K or more. At present, a terminal is upgraded by issuing an upgrade command to the terminal through a network management server, and the terminal initiates an upgrade request to the network management server and downloads an upgrade version from the network management server to a local for upgrading.
In a network with a large number of terminals, in the process of downloading an upgrade version from a network management server by the terminals, multiple concurrent requests often cause terminal upgrade failure due to insufficient performance of the network management server and bottleneck of uplink bandwidth of a local side. The terminal which fails in the upgrade continuously repeats the download request, which further aggravates the congestion of the whole network, so that the upgrade process of the whole network is slow, and the upgrade process influences the normal service access.
