Method and system for realizing SNMP management of optical-fiber coaxial cable access network terminal equipment

Abstract

The invention discloses a method and system for realizing the SNMP management of optical-fiber coaxial cable access network terminal equipment, comprising the following steps: the terminal equipment requests a master-control exchange board to allocate an intranet IP address; the master-control exchange board receives the requests of the terminal equipment and allocates the intranet IP address to the terminal equipment; a backend system sends an SNMP management message to the master-control exchange board; the master-control exchange board receives the SNMP management message; and the master-control exchange board transmits the SNMP management message to the corresponding terminal equipment of the access network at the IP layer. In the invention, main Agent transmits the SNMP management message to the corresponding sub Agent of the terminal equipment on the IP layer instead of the application layer; not only the advantages that the SNMP management mode is efficient and fast are fully used, but also a large amount of public network IP addresses are saved, and the management efficiency of SNMP is increased. The invention can realize the network with manageability and maintainability,and satisfy the normal topology discovery and the allocation and maintaining of daily networks of users, thereby improving the operation reliability of networks and reducing the fault rate of networks.

Description

technical field [0001] The invention belongs to the technical field of Ethernet passive optical network (EPON), relates to a method for SNMP management, in particular to a method for realizing SNMP management of optical fiber coaxial cable access network terminal equipment by using management IP address conversion. Background technique [0002] Applying EPON and Ethernet data transmission technology based on the coaxial cable medium to the two-way transformation of the cable TV network, the original cable TV HFC (Hybrid Fiber Coax, optical fiber / coaxial hybrid) network can be used to integrate traditional TV services, voice It is a trend in the development of cable TV network to realize the integration of three networks through IP technology for business and broadband Internet access. 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 the coaxial h...

Problems solved by technology

[0005] 1. Since the SNMP management information of the access network terminal equipment needs to be parsed by the main Agent program of the OLT main control board and forwarded to each sub-Agent, the message forwarding efficiency will increase with the increase in the number of terminal equipment. Greatly reduced, especially when the background network management system of the access network updates the topology for device discovery, the topology discovery may not be completed due to timeout

[0006] 2. Each terminal device needs to manually configure the IP address, and the large number of terminal devices increases the difficulty of network maintenance.

At the same time, it will also occupy a large number of public network IP address resources, making the access network an extremely difficult network to maintain

[0007] 3. When the requirements of the network management change, not only the sub-Agent function of the terminal equipment needs to be updated, but also the main Agent function of the main control board needs to be modified appropriately, which is not conducive to the maintainability and relative independence of the software version

However, these implementation methods are based on application layer forwarding, and the performance of the SNMP message forwarding module is the bottleneck to improve the management efficiency of the entire access network

Especially when the number of terminal devices is large, this bottleneck will affect network management
