Problems solved by technology

With the large-scale application of CBAT, manual configuration of IP is not effective for network maintenance and management. Due to human operation factors, sometimes there will be errors in the management IP and management VLAN settings of these data, which will cause CBAT to be unable to use and manage normally. Even if the management IP settings are the same, it cannot be detected, resulting in a decrease in the accuracy of management data; on the other hand, in order for the OLT to monitor whether the CBAT is online at all times, the CBAT is required to periodically (1 minute by default) send a discovery message to the OLT, even if the CBAT already exists in the CBAT entry of the OLT
Since the payload field payload of the discovery message is composed of multiple TLV (Type-Length-Value) formats, when the OLT system is fully configured with CBATs, each CBAT periodically sends self-discovery messages, which will increase the entire EPON / GPON+CBAT system load

Embodiment 1

[0038] see figure 1 As shown, the embodiment of the present invention provides a kind of CBAT management method, based on Ethernet coaxial technology, is used for managing CBAT, realizes automatic registration and configuration of CBAT, comprises the following steps:

[0039] S1. The coaxial cable broadband access network device CBAT periodically sends an extended self-discovery ECDBP message to the optical line central office OLT through the optical network unit ONU; the ECDBP message includes an identifier indicating the message type. Specifically, the ECDBP message includes an extension field with an identifier, and the identifier includes a registration identifier, a heartbeat identifier, a heartbeat response identifier, and a configuration identifier.

[0040] S2. The OLT will judge the message type of the received ECDBP message according to the identifier. When the ECDBP message received by the OLT is a registration message for CBAT to report its own information, and the...

Embodiment 2

[0054] On the basis of embodiment 1, see Figure 5 As shown, it is the detailed processing flow of the OLT receiving the ECDBP message, which specifically includes the following steps:

[0055] a201. The OLT receives the ECDBP message and judges the message type;

[0056] When the ECDBP message received by the OLT is a registration message, turn to a202;

[0057] When the ECDBP message that OLT receives is a heartbeat message, detect the online state of CBAT by this heartbeat message, and turn to a204;

[0058] a202. judging whether the same CBAT entry exists locally in the OLT, if yes, then turn to a204, if not, then turn to a203;

[0059] a203. The OLT requests the extended self-configuration of the CBAT from the EMS or the NMS, and sends it to the CBAT through the ONU, and ends.

[0060] a204. The OLT sends the ECDBP message carrying the heartbeat response identifier to the CBAT through the ONU, notifying the CBAT that the entry already exists on the OLT, and there is no...

Embodiment 3

[0063] On the basis of embodiment 1, EMS or NMS pre-sets at least one IP distribution strategy, and includes multiple address pools in each IP distribution strategy; When EMS or NMS receives the configuration request message of OLT, selects the IP distribution corresponding to CBAT Find the corresponding address pool in the IP allocation policy; then send the address segment of the corresponding address pool to the OLT as an extended self-configuration.

[0064] If there is no IP allocation policy or address pool corresponding to the CBAT in the EMS or NMS, a default address segment is allocated and sent to the OLT as an extended self-configuration.

[0065] In the actual process, after the EMS or NMS receives the creation or update event message sent by the OLT, the user only needs to select the CBAT to be configured on the EMS or NMS, and the EMS or NMS will assign a unique IP to the CBAT according to the IP allocation policy and VLAN, as well as gateway address and subnet m...

Abstract

The invention discloses a CBAT management method and system, and relates to the field of integration of three networks. The method comprises the following steps: a CBAT periodically sends an extensionself-discovery ECDBP message to an OLT through an ONU, wherein the ECDBP message comprises an identifier indicating a message type; when the ECDBP message received by the OLT is a registration message and the OLT does not have the same CBAT entry locally, the OLT requests extension self-configuration of the CBAT from a network element management system EMS or the NMS, and sends the extension self-configuration to the CBAT through the ONU; and the CBAT makes the extension self-configuration take effect. By adoption of the CBAT management method and system disclosed by the invention, automaticregistration and configuration of the CBAT are achieved, the load of an EPON / GPON+CBAT system can not only reduced, effective real-time monitoring of the CBAT can also be achieved, and the efficiencyof EPON / GPON+CBAT network maintenance and management is improved.

Description

technical field [0001] The invention relates to the field of triple network integration, in particular to a CBAT (Coaxial Broadband Access Terminal, coaxial cable broadband access network equipment) management method and system. Background technique [0002] In the early stage, the network topology of G / EPON (Gigabit / Ethernet Passive Optical Network, Gigabit / Ethernet Passive Optical Network) + EOC (Ethernet Over Cable, Ethernet signal coaxial transmission) system can only be maintained and managed manually. When installing the CBAT of the EOC system, you must first turn on the CBAT all-in-one device, configure the management IP and management VLAN (Virtual Local Area Network, Virtual Local Area Network); due to the large number of CBAT, after investigation, it is found that these data information cannot be entered manually. Waste of resources, low efficiency and very high error rate, so manual methods cannot carry out effective network maintenance and management. [0003] A...
