Method for carrying out topology association on optical network unit (ONU) and Ethernet over coax (EOC)

Abstract

The invention provides a method for carrying out topology association on an optical network unit (ONU) and Ethernet over coax (EOC). The method comprises the following steps that: S1) an EOC process establishes a topology structural table of a coaxial cable Ethernet device; S2) an ONU process on the optical network unit carries out network communication with the EOC process through a loopback address; S3) the ONU process on the optical network unit compares the CBATMAC with a media access control (MAC) address list of a user network interface according to the topology structural table transmitted by the EOC process; and S4) the topology structural table between the optical network unit and the coaxial cable Ethernet device is established according to the comparison result. By the method, the EOC and the Ethernet passive optical network (EPON) are associated, and a topology structure among the ONU, CBAT and CNU can be obtained from an EPON network management system.

Description

technical field [0001] The present invention relates to the field of communications, including Ethernet switches, EPON (Ethernet Passive Optical Network) systems, GPON (Gigabit Passive Optical Network) systems, and EOC (Ethernet over Coaxial Cable) systems, in particular to communication equipment integrated service optical The method of ONU (Optical Network Unit) and EOC topology association in nodes (including ONU and coaxial line terminal CLT). Background technique [0002] Defects of traditional EOC network management: [0003] (1) The EOC main control is a single board or a chip, and the main control is connected to 1 to 4 CBAT (coaxial cable broadband access network central office equipment) boards; when networking, ONU equipment must be deployed separately; [0004] (2) The EOC main control is connected to the ONU, which generally requires ONU multi-network ports or single-network port multi-VLAN (virtual local area network) management; [0005] (3) The network port...

AI Technical Summary

Problems solved by technology

[0005] (3) The network port where the EOC main control is connected to the ONU is designed and planned in advance, and no line connection errors are allowed;

[0006] (4) The EOC network has nothing to do with EPON, and it is impossible to know the EOC network deployed under it from the EPON network management
