Equipment unified management method for Ethernet passive optical network and Ethernet over coax (EPON+EoC) two-way cable access network

Abstract

The invention provides an equipment unified management method for an Ethernet passive optical network and Ethernet over coax (EPON+EoC) two-way cable access network. The method comprises the following steps that: an Ethernet over coax (EoC) high performance switch transmits a registration request to Ethernet passive optical network (EPON) local side optical line terminal equipment based on a group management protocol; after receiving the registration request, information transfer equipment attaches identification information and the physical connection topology information of equipment managed by the information transfer equipment to the registration request and uploads the registration request; and after the EPON local side optical line terminal equipment receives the registration request attached with the physical connection topology information, the EPON local side optical line terminal equipment calculates a corresponding management address according to the physical connection topology information comprised by the registration request and a preset address calculation method, and transmits the management address to the EoC high performance switch, so that the EoC high performance switch correspondingly sets the management address of the EoC high performance switch; therefore, the unified management of the EPON local side optical line terminal equipment is realized, and the physical connection topology of high performance switch (HS) equipment can be automatically discovered.

Description

technical field [0001] The invention relates to a method for unified management of equipment, in particular to a method for unified management of equipment used in an EPON+EoC wired bidirectional access network. Background technique [0002] Applying Ethernet passive optical network (EPON) and Ethernet data transmission technology (EoC) based on coaxial cable medium to the two-way transformation of cable TV network, the original cable TV HFC (Hybrid Fiber Coax, optical fiber / coaxial Mixed) network, the traditional TV service, voice service, broadband Internet service, through IP technology to achieve triple play, is a trend in the development of cable television networks. Without abandoning the original HFC network resources of cable TV, the EPON optical link is used to provide high-speed optical fiber access from the front end to the corridor, and then the coaxial high-speed Ethernet transmission technology is used to realize the high-speed copper axis cable access in the c...

Problems solved by technology

[0005] The first aspect: the deficiency of the discovery of the physical connection topology between the OLT device and the HS device is that when checking the MAC address learned by the PON port, there will be a lot of MAC address information, most of which are not managed by the HS device, and cannot be quickly Determining which MAC addresses are the management MACs of HS devices makes viewing the physical connection topology of HS devices very inefficient and error-prone

[0006] The second aspect: the shortcomings of configuring the internal management IP address locally through the HS device are: (1) There are many steps to configure the IP address of the HS device, and the operation is cumbersome, and it is not suitable for large-scale HS device operations; (2) Each operation can only be configured locally on the HS device, and cannot support remote configuration management before obtaining the management IP address

[0007] The third aspect: the shortcomings of obtaining the internal management IP address through the DHCP method are: (1) need to configure the DHCP server, and ensure that the intermediate network between the HS device and the DHCP server is connected; (2) the physical connection topology of the HS device There is no direct correlation between discovery and assigned internal management IP addresses, and unified management cannot be formed

Due to the various deficiencies mentioned above in these solutions, it will be difficult to manage access devices when performing unified management of large-scale HS devices
