Abstract
Disclosed is a system and a method for polling in an Ethernet Passive Optical Network (EPON). The system includes: multiple Optical Network Units (ONUs) for sharing optical channels of the EPON with one another and transmitting traffic; and an Optical Line Terminal (OLT) for discriminating a plurality of ONUs gaining access to the EPON among the multiple ONUs and then collecting routing information on the plurality of ONUs gaining access to the EPON, and for classifying the plurality of ONUs gaining access to the EPON into two or more ONU groups according to the collected routing information and then carrying out forming a polling cycle and allocating bandwidth on each ONU group. Therefore, a transmission idle period in a traffic channel is not only minimized, but an availability ratio of traffic channels can also be maximized.
