Assume the workstation uses direct memory access (DMA) to move data in and out of its main memory, which has a bandwidth of 2 Gbps, and that the I/O bus has a bandwidth of 1 Gbps. At what packet size would the bus bandwidth become the limiting factor?Suppose you are designing a sliding window protocol for a 1-Mbps point-to-point link to a stationary satellite revolving around the earth at 3 x 104 km altitude.

Assume that both ACK and data frames have 320 bits of header information, and that ACK frames carry no data. What is the effective data throughput When using sliding windows with a sender window size of W = 5 data frames?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. R4: p = The image is being sent through a link of bandwidth 7 MBPS and device B is 3500 Km away from device A. The signal passes through the link at a speed of 2.5x10^8m/s. Considering there is no queuing time, calculate the total delay for this transmission.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?
