Question
long will it take the IDENT field of the IPv4 header to wrap around, if the sender (3.0) How host A sends a stream of packets to host B as fast as possible? Assume the packet size is 1500 bytes and the bandwidth is 600 Mbps. (4.0) The following diagram has routers A, B, C, D and E: E is the "border router connecting the site to the Internet. All router-to-router connections are via Ethernet-LAN /24 subnets with addresses of the form 200.0.x. Give forwarding tables for each of Ao, B, C and D. Each table should include each of the listed subnets and also a default entry that routes traffic ter E. Directly connected subnets may be listed with a next hop of "direct 200.B. 8 -E" Internet 209.0.9 200.0.18Explanation / Answer
3.0 IP identification field value is 16 bit. and this field describes the how many number of packets can be sent with identification number. so there are total 2^16 packets can be sent to wrap around identification field.
time to send 1 packet = 4000*8/600*2^20 , time to send 2^16 packets = (2^16*4000*8)/(600*2^20) = 3.33 seconds
