Assume that you are working for an International company that headquarters is in New York and your branch office is in Girne. You want to setup VPN connection from Girne to New York. You have four different paths along the way. First path (Girne-Anamur) that uses radio link, distance is about 80 km and bandwidth is 40Mbps. Next part (Anamur-Istanbul) uses fiber optic line distance is about 700 km and this part bandwidth is 20Mbps. Other part of this path (Istanbul - London) also uses fiber-optic link that distance is about 2500 km and bandwidth is 8Mbps. Last part of this path (London-New York) connects via GEO Satellite and bandwidth is 4Mbps, Assume that you want to send 800 Mbyte video file from Girne to New York. Calculate total nodal delay with following values No queuing delay, all nodes have VPN processing delay 4 msec/MByte, geostationary satellite altitude 36000 km, free space propagation speed 2.5x108 m/sec propagation speed 3x108 m/sec
