 In the past one decade explosive growth has been seen in internet traffic. This growth has demanded for more and more bandwidth of communication media, and very fast configurability of connecting devices. To meet these requirements optical fiber communication can be used. In the similar context optical burst switching (OBS) is considered as good alternative for current electronic system. In OBS, for contention resolution deflection routing is preferred choice, but burst loss performance in deflection routing is very poor. As an alternative, buffering of contending burst can be used, but as the size of bursts is random thus buffer size cannot be fixed in advance. To solve such problem, in this paper, a burst length estimation analysis is presented, while keeping both over-reservation and average waiting time at minimal. And using the asymptotic analysis burst length is fixed. For the fixed burst length buffer can be designed very easily to obtain required burst loss probability.
