2. (a) Suppose an end device A wants to send a frame containing a black and white image to another end device B. There are a total of 4 routers(R1,R2,R3,R4) in between them. The image being sent is a 1080*1920 pixel image. Every pixel is represented with 1 bit. The processing time(p) of each router in given below: I. R1: p = 1µs II. R2: p = 1.5μs III. R3: p = 2µS IV.

Problem 3 Consider the problem of deciding whether to implement a virtual- circuit or a datagram network. Assume a network protocol that allows the system to operate as either a virtual circuit network or a datagram network. That is, its packet header format is specified such that it incorporates both a VCI (Virtual Circuit Identifier) and an arbitrary source/destination addresses. When operating as a virtual circuit, it requires a 4-byte header. When operating as a datagram network, it requires a 40-byte header. Assume that there are 4 hops from source to destination, and that a set up or tear down request packet is 80 bytes (including the header). The total message length is 4096 bytes, the data rate is 9600 bps on all links and the packet size is 256 bytes (including the header). i) If we operate in the datagram mode, how long does it take for the first packet to reach the destination? If we operate in virtual-circuit mode, how long does it take for the first packet to reach the…
In a flooded frame, an unknown destination address is frequently utilized.
Discuss the invocation semantics that can be achieved when the request-reply protocol is implemented over a TCP/IP connection, which guarantees that data is delivered in the order sent, without loss or duplication. {Note: Take into account all of the conditions causing a connection to be broken}
Problem 5: Draw a Mealy FSM to model a LAN adapter. Serial data packets entering the FSM are analyzed. The start of a packet is indicated by the arrival of two consecutive 0's on the input line . The next three bits are the machine address. The targeted addresses are 100 or 110 where an output = 1 is generated. Any other addresses produce a zero at the output. A separate reset mechanism will put the machine in the initial state (i.e, you should never return to the initial state in your design).
