Alarge ipv4 datagram carrying a 20 byte header and 2500 bytes of payload data (total packet length is 1520 bytes) is fragmented to pass over a network where the mtu is 1500 bytes. assume the identification of the original datagram is 123. for each fragment, show the contents of the identification field, the offset field, the total length field, and the more fragments flag in the ip header. 3. an ipv6 packet has a 40 byte base header, a 20 byte destination options extension header (which is not used for routing) and 2000 bytes of payload data (total packet length is 2060 bytes). this is to be fragmented to travel over a network with a mtu of 840 bytes. considering the fragmentable and unfragmentable parts of this packet, create a sketch showing the headers and data in each fragment, including the number of bytes. don’t forget the fragmentation header, which is 8 bytes. 4. a large ipv4 datagram is fragmented into 3 fragments at router 1 to pass over a network with an mtu of 1500 bytes. assume each fragment is larger than 900 bytes. then, each fragment arrives at router 2, which wants to forward the fragments over a network with an mtu of 900 bytes. how many fragments will arrive at the destination host

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx,fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx,fs) does automatic scaling and then calls sound(xx,fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2
