Problems solved by technology

[0006] (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;
[0007] (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

Embodiment Construction

[0043] Such as image 3 As shown, the system structure of the present invention is: PC network management (EPON network management) runs on the OLT, and the OLT is connected to multiple ONUs through an optical splitter. Each ONU contains multiple UNIs, and a CBAT is connected to the UNIs. The CBAT is connected to multiple CNUs through an electrical splitter. One coaxial cable card of CBAT is used as CLT. ONU and CLT are integrated in an integrated service optical node device, such as VISTA-B05-224 of Guangdong Dongyan Network Technology Co., Ltd. VISTA-B05-224 is a three-in-one terminal product launched for FTTC (fiber to the curb) + EOC networking, providing radio and television users with EPON\EOC\HFC (hybrid fiber coaxial cable) comprehensive business solutions. Multiple processes can run on the CPU of the optical network unit device, such as: ONU APP (application program) and EOC APP. UDP network communication is performed between ONU APP and EOC APP, and ONU and EOC p...

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

[0001] technical field [0002] 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 [0003] Defects of traditional EOC network management: [0004] (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; [0005] (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; [0006] (3) The net...
