Abstract
The invention discloses a centralized management system for Ethernet over coax (EOC) products. The problem of incompatibility caused by the great number of EOC access point (AP) manufacturers and the problems of interconnection and intercommunication of each EOC terminal are solved, the cost of APs is lowered, better quality of service is provided, and the investment of an operator in operation and maintenance is effectively lowered. According to the technical scheme, the system comprises a centralized management server for the EOC products and the APs, wherein the centralized management server directly communicates with the APs through a switch or an optical line terminal (OLT) in a media access control (MAC) layer, and is used for performing unified management on EOC modules in the APs connected with the centralized management server in the MAC layer.
Description
Technical field
The present invention relates to a kind ofly transmit Ethernet data (EOC by coaxial cable, Ethernet Over Coax) related system of product, relate in particular to the system that a plurality of EOC headend AP (Access Point, headend) are carried out 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 (family's power network) product comes true gradually.EOC product origin is for home network, and afterwards because it can provide high bandwidth, and price has more advantage with respect to other access waies, and increasing operator selects EOC as the access way of last kilometer.
The EOC product has inborn defective owing to beginning to be positioned home network on its way to manage.The management of EOC is distributed management.An AP is in charge of one or several EOC module, and the interface of the management of a SNMP (Simple Network Management Protocol, simple NMP) is provided, and the server of catching up with the webmaster of layer communicates.
This way to manage has following shortcoming:
1.EOC producer too many, there is the software of oneself in each producer, although each manufacturer of Carrier Requirements will provide the interface of identical SNMP, but on equipment self implementation, and equipment vendors are for MIB (Management Information Base, all that certain difference is arranged on the dynamics of support management information bank), so cause for the management of each AP very difficult.
2. can not accomplish real interconnecting.In the EOC network system, except normal AP, each manufacturer also provides EP (End Point, terminal).Because each EP architecture and software are not quite similar, often can not communicate by letter between the EP of different manufacturers and AP.Operator will spend great energy to safeguard the equipment that numerous manufacturers provides in addition, can interconnect to guarantee them.
3.AP cost high.In the EOC network, AP and EP are the entities of equity, are duplicate from their function of angle of network.But because AP will bear too much management function, equipment vendors tend to so virtually increase the cost of equipment to CPU and peripheral components that performance is stronger of AP configuration.
4. can not provide service quality preferably.The function that does not possess backup due to AP itself is so the network outage that whole AP manages in the time of the software crash of AP can cause user network to interrupt like this.
5. increase the maintenance cost of operator.Because operator will be responsible for safeguarding all AP, and because AP bears too much management role now, so operator will spend very large manpower, material resources and financial resources to remove to safeguard existing product.
Summary of the invention
The object of the invention is to address the above problem, the centralized management system of a kind of coaxial cable transmission Ethernet data product (EOC product) is provided, solved the too many incompatibility problem of bringing of EOC AP manufacturer, solved the problem that interconnects of each EOC terminal, reduced the cost of AP, better service quality is provided, and has effectively reduced the input of operator in operation maintenance.
