Journal of Internet Services and Applications

Table 2 Port behavior zones

Zone ID	Port role	Port zones
1	Client Port	$\begin{array}{l} - δ \leq B_{i} \leq β, - ϕ \leq A_{i} \leq φ \\ - δ \leq B_{i} \leq β, φ < A_{i} \leq 2 - γ \\ - δ \leq B_{i} \leq β, 2 - γ \leq A_{i} \leq 2 \\ - δ \leq B_{i} \leq β, A_{i} < - ϕ \\ B_{i} < - δ \\ B_{i} > β \end{array}$
2	Service Port
3	P2P Port
4	Overlay Port
