  23. Conclusion • Proposed PSC-WDM PON Architecture and Multicast Algorithm with priority. By using simulation result ,compare the achieved performances with those from AWG-WDM PON, TDM PON (four PON combined) architectures . • Propose three different multicast access protocols, called LBQAP Protocol、STTLF Protocol and PSTTLF Protocol, for be employment in an asynchronous slotted optical star network with priority.

  24. Feature works • Many fixed receivers composed an receive array. • A proper scheduling to transmit unfixed length packets. • Extension PSC Star PON .
