Problems solved by technology

[0007] Aiming at the above defects or improvement needs of the prior art, the present invention provides a method and system for upgrading ONU based on point-to-group mode. Compared with the traditional OMCI / OAM unicast method, it improves the data transmission efficiency and reduces the time spent on file transmission; moreover, most of the data transmission is between ONU and ONU, which is not limited by the characteristics of the OLT protocol stack and also There will be no excessive waste of CPU resources, thereby solving the technical problems of low upgrade efficiency, long upgrade time, and OLT memory / CPU resources being occupied by too many upgrade files

Embodiment 1

[0055] refer to figure 1 , the present embodiment provides a system for upgrading ONUs based on a point-to-group method, the PON system includes an OLT and a plurality of ONUs, the OLT is configured as a scheduling server, and the ONU is configured as a client, wherein the PON system includes EPON system or GPON system, whether it is an EPON system or a GPON system, the implementation mechanism of upgrading the ONU in the point-to-group mode is the same. In the EPON system, an independent OMCI protocol stack is usually used for information exchange, and in the EPON system, an independent OAM protocol stack is usually used for information exchange. Among them, the point-to-group refers to the use of multicast to transmit data between the client and the client group, and the client group refers to all clients in the same multicast group, that is, when a certain client is used as the transmission source , you can transfer data to all clients under the client group.

Embodiment 2

[0070] refer to Figure 4 , the present embodiment provides a method for upgrading an ONU based on a point-to-group method, the method is applied to a PON system, the PON system includes an OLT and a plurality of ONUs, the OLT is configured as a scheduling server, and the ONU is configured as Client, described method comprises the steps:

[0071] Step 10: The scheduling server receives a preset multicast address preset table, and determines the multicast group to which each client under the OLT belongs based on the multicast address preset table.

[0072] In actual application scenarios, you can create Tracker services in the OLT to configure the OLT as a scheduling server (Tracker), and create a Peer service in the ONU to configure the ONU as a client (Peer).

[0073] In this embodiment, the upgrade file is transmitted in a multicast manner, wherein one multicast group includes multiple clients. Wherein, the way of establishing the multicast group is: the scheduling server ...

Embodiment 3

[0107] Combine below Figure 5 , briefly explain the implementation process of the foregoing embodiment 2:

[0108] Step S1: OLT initiates ONU batch upgrade operation:

[0109] Wherein, step S1 specifically includes the following steps:

[0110] Step S101: the OLT downloads the upgrade file from the server to the local;

[0111] Step S102: OLT registers itself as the first seed to all Trackers in the system;

[0112] Step S2: The OLT notifies all eligible ONUs to be upgraded;

[0113] Wherein, step S2 specifically includes the following steps:

[0114] Step S201: the OLT sends a control message to the ONU to start upgrading;

[0115] Step S202: The ONU registers itself as a Peer to the Tracker of the board to which it belongs;

[0116] Step S3: Tracker periodically polls the local Peer list;

[0117] Wherein, step S3 specifically includes the following steps:

[0118] Step S301: Select the multicast group A to which the Peer with fragmentation missing belongs as the tr...

Abstract

The invention discloses a method and system for upgrading an ONU based on a point-to-group mode. The method comprises the steps: receiving a multicast address preset table, and determining a multicastgroup to which each client under an OLT belongs based on the multicast address preset table; acquiring the upgrading file via the OLT , and analyzing the upgrading file to determine a target client matched with the upgrading file; establishing a client list based on the target client, the multicast group to which the target client belongs and the downloading progress of the target client; dividing the upgrade file into a plurality of file fragments, scheduling a server to periodically poll a client list, taking a multicast group to which a first client lacking the file fragments to be transmitted belongs as a transmission target, taking a second client having the file fragments to be transmitted as a transmission source, and notifying the second client to transmit the to-be-transmitted file fragment to the multicast group to which the first client belongs in a multicast mode. According to the method disclosed in the invention, file transmission is carried out in a point-to-group and multicast combination manner, and therefore the data transmission efficiency is improved.

Description

technical field [0001] The invention belongs to the field of optical communication, and more specifically relates to a method and a system for upgrading an ONU based on a point-to-group method. Background technique [0002] In the PON (Passive Optical Network, abbreviated as PON) access system, the Optical Network Unit (Optical Network Unit, abbreviated as ONU) equipment is connected to the Optical Line Terminal (Optical Line Terminal) through the Optical Distribution Network (Optical Distribution Network, abbreviated as ODN) Terminal, abbreviated as OLT) equipment, OLT equipment manages and maintains the ONU equipment attached to it; when the ONU software function needs to be changed, the ONU needs to be upgraded; ONU is divided into SFU (Single Family Unit, abbreviated SFU), MDU (Multiple Dwelling Unit, abbreviated as MDU) and HGU (Home Gateway Unit, abbreviated as HGU) and other types; for MDU / HGU equipment, you can use the IP method (such as TR069) to upgrade from an ext...
