Reverse Engineering – Recent Advances and Applications
One can easily find that all peers in such a system will have the same offset lag L�Wtk. Buffer
width is an important design parameter involving playback performance. Larger buffer can
improve playback continuity, but does no good to a tracker for consuming more memories.
Thus, FP can’t fulfill two design goals at same time: large buffer of peer but small buffer of
tracker.
Let’s consider a more practical scheme named as proportional placement (PP) based on offset
lag, i.e., �=fp(t0)+�Lp, where � is constant placement coefficient less than 1, and Lp is the first
neighbor’s offset lag. Since the first neighbor must have been a new peer when it entered the
system, we can refer to a very familiar formula xn+1=bxn+c, which is a contraction mapping
when the Lipschitz condition satisfies b
