## P2PSP (Peer-to-Peer “Straightforward” Protocol)

#### Block rate

The stream $\mathsc{𝒮}$ $St$ is divided into an inﬁnite number of orthogonal? blocks ${\mathsc{𝒮}}_{i}$ $S{t}_{i}$ of size $\alpha$ such as $St={\bigcup }_{i=1}^{\infty }S{t}_{i}$, where $S{t}_{i}\cap S{t}_{j}=\varnothing$. The block rate is deﬁned by

 $Bs\left(t\right)=\frac{\alpha }{bs\left(t\right)}.$ (15)
