Homework #5 Answers Each problem/question worth 20 points Page 501-508 (Kurose and Ross) Review Questions: 2, 11 and 14 Problems: 5 and 17 Review Question : 2 Although each link guarantees that an IP datagram sent over the link will be received at the other end of the link without errors, it is not guaranteed that IP datagrams will arrive at the ultimate destination in the proper order. With IP, datagrams in the same TCP connection can take different routes in the network, and therefore arrive out of order. TCP is still needed to provide the receiving end of the application the byte stream in the correct order. Also, IP can lose packets due to routing loops or equipment failures.

Unformatted text preview: Review Question: 11 No, it is not possible. Each LAN has its own distinct set of adapters attached to it, with each adapter having a unique LAN address. Review Question: 14 After the 5th collision, the adapter chooses from {0, 1, 2,…, 31}. The probability that it chooses 4 is 1/32. It waits 204.8 microseconds. Problem: 5 If we divide 10011 into 1010101010 0000, we get 1011011100 , with a remainder of R= 0100. Note that, G=10011 is CRC-4-ITU standard. Problem: 17 Wait for 51,200 bit times. For 10 Mbps, this wait is (5.12 * 10 3 ) bits / (10 * 10 6 ) bps = 5.12 ms (millisecond) For 100 Mbps, the wait is 512 μs (microsecond)....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
