SYSTEM AND METHOD FOR POLLING IN ETHERNET PASSIVE OPTICAL NETWORK

摘要

A system and a method for polling in an Ethernet passive optical network are provided to increase the available rate of a traffic channel by minimizing an upper channel idle section caused by a rapid allocation of bandwidth and a pause interleave polling method. A polling system in an Ethernet passive optical network includes plural ONUs(Optical Network units)(200,300) and an OLT(Optical Line Terminal)(100). The plural ONU transmits a traffic by sharing an optical channel of the Ethernet passive optical network. The OLT collects the routing information about the ONUs by identifying plural ONUs. The OLT classifies the plural ONUs into at least two groups based on the routing information, and executes the allocation of the bandwidth and the formation of polling cycle for each group.
