Embodiment 1

[0019] Embodiment 1, this embodiment is a method for upgrading multiple devices among passive optical network devices. The networking involved in this method is as follows: figure 1 shown. A multicast upgrade server is an ordinary PC, which realizes batch distribution of upgrade files and management of terminal software versions. The intermediate network is OLT (Optical Line Terminal), which realizes the connection between the multicast upgrade server and multi-terminal devices. The multicast upgrade server and OLT are connected through WAN, and the necessary switch. The EPON terminal equipment is the passive optical network equipment ONU.

[0020] In this embodiment, through the network protocol of the second layer, the multicast upgrade server will issue the upgrade file and perform transparent transmission through the OLT. After the EPON terminal ONU receives the upgrade file, it will perform the upgrade. The literal meaning of transparent transmission is transparent tran...

Abstract

The invention provides a method for upgrading multiple devices between passive optical network devices. The method solves the problem of constraint on multi-terminal large-batch upgrade in a passive optical network. According to the technical scheme, a multicast upgrade server uniformly manages the versions of multiple terminals and realizes multi-terminal batch upgrade. The method has the advantages that networking is simple because communication is realized through two layers of network protocols; the multicast upgrade server and the terminals are in a two-layer network, upgrade files are transmitted through the multicast upgrade server and transmitted to the terminals through an optical line terminal (OLT), and the upgrade files are automatically processed for upgrading by the terminals; and the upgrade of the conventional network terminals is not limited by an OLT manufacturer, and the upgrade of storage terminals is not limited by terminal managed IP.

Description

technical field [0001] The invention relates to the application field of passive optical network terminal equipment (ONU), in particular to a method for upgrading each terminal equipment in a passive optical network equipment room. Background technique [0002] Passive optical network is a point-to-multipoint optical fiber access technology. This optical fiber access technology cancels the active equipment between the central office and the client. It can well avoid the electromagnetic interference of external equipment and reduce the number of lines. and the failure rate of external equipment, which improves the reliability of the system and saves maintenance costs. In recent years, related technical products have become more and more popular in the market, and will gradually replace traditional active network communication equipment. [0003] At present, the domestic passive optical network technology is widely used as EPON (Ethernet Passive Optical Network Ethernet Passi...
