A packet switching router receives a packet and determines the outbound link to which the packet should be forwarded. When the packet arrives, one other packet is halfway done being transmitted on this outbound link and four other packets are waiting to be transmitted. Packets are transmitted in order of arrival. All packets are 1500 bytes and the link speed is 2 Mbps. Signal propagates on the link at the speed of 2.5*10^8 m/sec and the length of the link is 100km. a. How long does the new packet wait before its first bit is transmitted?
b. How long does it take this packet to be completely received at the node on the other end of the link?
