Abstract
A session-based dynamic bandwidth allocation applied to PON includes the steps of A) duplicating, under PON system, packets transmitted to a splitter from every ONU and filtering the packets as per session classification via a snooping agent of the ONU to get specific packets; B) making every ONU transmit the specific packets to a bandwidth analyzer via a tunneling; C) analyzing information of the specific packets or the relativities between every specific packet and the previous and next packets via the bandwidth analyzer to further generate a session state information and save it into a database; and D) making an OLT access the session state information in the database and applying an SDBA to the dynamic bandwidth allocation.
