Abstract
The invention discloses a kind of centralized management system of co-axial cables transport Ethernet data product (EOC product), do you solve EOC? the incompatibility problem that AP manufacturer is too many brought, solve the problem that interconnects of each EOC terminal, reduce the cost of AP, provide better service quality, and effectively reduce the input of operator in operation maintenance.Its technical scheme is: system comprises Central Management Server and the headend AP of co-axial cables transport Ethernet data EOC product, Central Management Server by switch SWITCH or optical line terminal OLT MAC layer directly and headend AP carry out communication, by Central Management Server, in MAC layer, unified management is carried out to the EOC module in connected headend AP.
Description
Technical field
The present invention relates to a kind of by co-axial cables transport Ethernet data (EOC, EthernetOverCoax) related system of product, particularly relate to the system of multiple EOC headend AP (AccessPoint, headend) being carried out to centralized management.
Background technology
EOC product technology standard is very many, As time goes on and the progress of technology, and the standard on Homeplug (domestic electric mains) product comes true gradually.EOC product origin is for home network, and afterwards because it can provide high bandwidth, and price has more advantage relative to other access waies, and increasing operator selects EOC as the access way of last one kilometer.
EOC product, owing to starting to be positioned home network, its way to manage has inborn defect.The management of EOC is distributed management.An AP is in charge of one or several EOC module, and provides the interface of the management of a SNMP (SimpleNetworkManagementProtocol, simple NMP), and the server of catching up with the webmaster of layer communicates.
This way to manage has following shortcoming:
The producer of 1.EOC is too many, there is oneself software in each producer, although each manufacturer of Carrier Requirements will provide the interface of identical SNMP, but due in equipment self implementation, and equipment vendors are for MIB (ManagementInformationBase, management information bank) support dynamics on be all have certain difference, so cause the management for each AP very difficult.
2. can not accomplish real interconnecting.In the EOC network system except normal AP, each manufacturer also provides EP (EndPoint, terminal).Because each EP architecture and software are not quite similar, often can not communicate between EP and the AP of different manufacturers.In addition operator will spend great energy to safeguard the equipment that numerous manufacturers provides, to ensure that they can interconnect.
The cost of 3.AP remains high.In EOC network, AP and EP is the entity of equity, is duplicate from their function of angle of network.But because AP will bear too much management function, equipment vendors often configure the stronger CPU of performance and peripheral components to AP, so virtually add the cost of equipment.
4. can not provide good service quality.Because AP itself does not possess the function of backup, so the network outage that whole AP manages when the software crash of AP time, user network can be caused like this to interrupt.
5. increase the maintenance cost of operator.Because operator will be responsible for safeguarding all AP, and bear now too much management role, so operator will spend very large manpower, material resources and financial resources to go to safeguard existing product due to AP.
Summary of the invention
The object of the invention is to solve the problem, provide a kind of centralized management system of co-axial cables transport Ethernet data product (EOC product), solve the incompatibility problem that EOCAP manufacturer is too many brought, solve the problem that interconnects of each EOC terminal, reduce the cost of AP, provide better service quality, and effectively reduce the input of operator in operation maintenance.
