A Distributed CCMTS Management Method

Abstract

The invention discloses a distributed CCMTS management system and method. An optical line terminal (OLT) device arranged in a sub-headend room accesses the CCMTS of an optical node through an Ethernet passive optical network (EPON) cascade plate. An optical network unit (ONU) module of the CCMTS is connected with the OLT. A data over cable system interface specification (DOCSIS) module of the CCMTS is connected with the ONU module. The CCMTS is virtualized on the OLT into a radio frequency interface single plate. According to the distributed CCMTS management system, the OLT can directly configure and control the DOCSIS module of the CCMTS; when the CCMTS breaks down and is to be replaced or when software is upgraded, reconfiguration of the CCMTS can be realized automatically and the software is upgraded automatically. The CCMTS is simple and convenient to operate and maintain.

Description

technical field [0001] The invention relates to the field of radio and television technology, in particular to a distributed CCMTS management system and method. Background technique [0002] With the further implementation of the integration of three networks, there is a need to speed up the two-way upgrade and transformation of the cable television network in the radio and television industry in various places. CCMTS has become a new model for the two-way transformation of the broadcast and television network. [0003] CCMTS is based on PON and HFC network. PON technology is used for interconnection between sub-headends and optical nodes. Coaxial cables are used between optical nodes and users to enter the home. Network access is realized through CCMTS and CM equipment using the DOCSIS protocol. With the CCMTS solution, 100M broadband access can be easily realized without changing the existing HFC network, and it can adapt to future network development. It has the advantage...

AI Technical Summary

Problems solved by technology

Regardless of restarting the CCMTS or replacing the hardware of the CCMTS, it is necessary to back up and save the original configuration of the faulty CCMTS; after the replacement, it is still necessary to wait for its online registration, and manually reconfigure according to the original configuration parameters again, so that the CCMTS can Normal operation, it cannot be deployed offline, the operation and maintenance time is long, and the fault maintenance progress is seriously lagging behind

[0008] 2. The upgrade work needs to be carried out one by one

In the process of software version upgrade, the existing CCMTS management system must go to the site to load new software for each remote CCMTS one by one for upgrade, the upgrade workload is heavy and the efficiency is low

[0009] 3. IP address allocation is unreasonable

This causes the IP addresses of CCMTS with fast development of some users to be tight, while the IP addresses of CCMTS with slow development of other users are idle. It is necessary to check whether the IP address pool of each CCMTS is sufficient, and the IP addresses between CCMTS cannot be shared, which seriously reduces the IP Address utilization, resulting in waste of resources

[0010] 4. The network management topology is complex

In the distributed CCMTS network management system, each CCMTS is an independent network element. In the case of mass deployment, it will inevitably affect the collection performance of the entire network management system. At the same time, the topology diagram is also very complicated, making it difficult to find information

[0011] 5. The login procedure is cumbersome

The configuration process is repeated, and the user identity needs to be logged in and verified multiple times, and multiple interfaces need to be opened when logging in to different CCMTSs. Not only is the configuration work cumbersome, but it is also easy to cause confusion for the operation and maintenance personnel, and prone to configuration errors
