Exercise2. Imagine you have been given the following scenario: - A files of size : F=20 Gbits - F is present in servers S1 and S2 respectively. S1 and S2 have upload speeds us=100 Mbps respectively, N=5, number of peers ui={12,17,18,27,16}, peer upload capacities in Mbps di={10,15,40,18,20}, peer download capacities in Mbps Assume the S1 and S2 are in consensus that they will share the load of distributing the file among all peers and all network communications are being done solely to send/receive the file, calculate the minimum (lower bound) time needed for distributing a file using the P2P architecture
