Abstract:
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.

Abstract:
A method for dispersing a terminal race in the contention access section of superframe for improving the stability of network is provided to reduce the number of frames by reducing the number of terminals. An association request command is transmitted to a PAN coordinator(S5). It confirms whether the PAN coordinator approves the participation of the terminal with reference to macAccessPermit(S8). It senses whether there is a resource according to a request. If a partitioned contention access mechanism support field is one, the PAN coordinator allocates a sub period to the terminal with reference to the information about the number of terminal. The PAN coordinator produces a participation success response message including the combination state field data(S16).
