IV. CONCLUSION
In this paper, firstly the broadband access technology including optical access technology, wireless access technology and FiWi technology is discussed. The placement of ONU is such that it support the internet traffic as well as p2p traffic. For that a different ONU placement algorithms considering both internet traffic and p2p traffic is studied. For ONU placement in internet traffic we study random, greedy and SA algorithm. From literature survey it is examined that greedy algorithm performs very well but at higher deployment cost than SA. The LBOP algorithm discussed in the literature considered both internet traffic and p2p traffic which minimizes the number of ONUs required in the network. From literature it is examined that the performance of LBOP algorithm is less than Tabu search algorithm but LBOP algorithm is cost efficient.
