An EOC energy-saving method based on epoc

Abstract

The invention provides an Ethernet over coax (EOC) energy saving method based on an Ethernet passive network over coax (EPOC). The EOC energy saving method includes that: a communication line terminal (CLT) is used for detecting uplink data and downlink data flow information of a CNU to determine whether the CNU can enter the energy saving state; when the CNU enters the energy saving state under control of the CLT, the CNU closes a transceiver arranged between the CNU and the CLT; after the CNU reaches a dormancy interval, the CNU automatically enters an awakening state and waits awakening authorization transmitted by the CLT; and when the CLT detects that the CNU should quit the energy saving state, the CLT transmits the awakening authorization to the CNU and then receives uplink data of the CNU. The EOC energy saving method is based on unified management and scheduling on the CNU carried out by the CLT, achieves automatic adjustment of the CNU state, and achieves the purpose of energy saving.

Description

technical field [0001] The invention belongs to the field of access network, and specifically relates to an energy-saving technology for access products based on EOC (Ethernet Over Coax, Ethernet over coaxial cable). Background technique [0002] With the rapid growth of telecommunication network bandwidth and the rapid expansion of scale, the energy consumed by the entire network is also increasing. Whether it is from the perspective of energy saving and emission reduction or reducing operating costs, energy saving in telecommunication networks is very important. . In the telecommunications network, the broadband access system has a large number of communication devices, and the energy consumption is much higher than that of the core network and the metropolitan area network. If the energy consumption of the broadband access network can be reduced, it will undoubtedly be beneficial to the energy saving of the telecommunications network. very significant.

Problems solved by technology

[0003] EOC technology does not have a unified technical standard, and there is a big gap between various solutions from definition to implementation; the definition of the MAC layer is not detailed, there is no MPCP (Multi-point Control Protocol, multi-point control protocol) control sublayer, and there is no OAM (Operation, Administration&Maintenance, operation, management and maintenance) control sublayer, even without clock synchronization

Moreover, various technical solutions have their limitations, and cannot guarantee the high-demand QOS (Quality of Service)

The above reasons increase the difficulty of implementing energy-saving technology on EOC
