3. The fields in a PPP header are as follows (source: Point to Point Protocol Structure) (Alternate source: TCPI Guide.com) Using the correct data types (this is essential to the assignment), design a data structure in C++ language that would represent this frame. Please use 10 bytes for the information and 5 bytes for the padding. Name Number of bytes Description Flag 1 0x7E, the beginning of a PPP frame Address 1 0xFF, standard broadcast address Control 1 0x03, unnumbered...

Problem 14: Consider sending a 2400-byte datagram into a link that has an MTU of 800 bytes. Suppose that the original datagram is stamped with the identification number 228. How many segments are generated? What are the values in the length, ID, fragment flag, and fragment offset in each fragment? (Assume 20 bytes of IP header)

3. A client application generates 10000 bytes to be sent to a server. TCP adds 160 bits as header for each Layer 4 segment and creates 10 segments. Each TCP segment is carried by an IP datagram with a 160 bit header. The IP datagrams form the payload of Ethernet, which has a 176 bit header and a 32 bit CRC. How many bits of data are sent on the physical medium to complete the transmission of all of the...

Host A wants to transfer 5000 bytes of data to Host B. On the network path there are two routers. First router R1, has MTU(Maximum Transformation Unit) of 1900 bytes. Second router R2, has MTU of 900 bytes. How many packets will Router 1 will deliver to Router 2 ? Draw packet formats with More Flag and Offset values and data sizes for each datagram for R1 . How many packets will Router 2 will deliver to Host B ?...

Suppose the MAC layer frame is up to 500 bytes. Each header or trailer is 60 bytes: a) What is the overhead? b) Consider a message of 1 M byte. Suppose the frame drop probability is p=0.1. How many bytes have to be transported to deliver the 1 M bytes user message, considering only one hop? c) If not limiting frame size, what is the optimal frame size?
