Scheme that causes the most faults: a) First in First out b) LRU and FIFO are the same number of faults c) FIFO and Opitimal are the same number of faults d) All have the same number of faults e) Least Recently Used f) No faults occurs g) LRU and Optimal are the same number of faults h) Optimal NUMBER OF FAULTS CAUSED: a)Computer A uses the Go-back-N ARQ protocol to send a 110 Mbytes file to computer B with a window size of 15. Given each frame carries 100K bytes data. How long does it take to send the whole file (the total time taken from A sending the first bit of the file until A receiving the last acknowledgment)? Given that the transmission rate of the link is 500 Mbps and the propagation time between A and B is 15ms. Assume no data or control frame is lost or damaged and ignore the overhead due to header and trailer.Compare and contrast the following four mechanisms for breaking up a bitstream into frames (make sure to give the pros and cons for each and provide examples of each schema in the context of transmitting the message "A B ESC FLG FLG A": byte count flag bytes with bit stuffing flag bytes with byte stuffing physical layer coding violations
- The following bit stream : 0111110001010011111111100101111111111110 represents data that needs to be framed by the link layer on the sender’s side. Derive the resultant bit stream by adding necessary flag bits and performing bits stuffing. assume that the link layer uses the flag bits with bit stuffing approach for framing, with the following details: The beginning and end of a data frame are indicated by the special flag bits 01111110 (i.e., 0x7E). To handle accidental occurrence of the flag bits within the data, a 0 bit is stuffed every time 5 consecutive 1s are found in the data. For simplicity, assume that no other header/trailer information is added to the data. I got this answer below but it is wrong. 0111111001111100001010011111011110010111110111111011001111110Can you describe the differences between asynchronous, synchronous, and isochronous connections and provide some instances of each? Can you also address whether or not there is a significant difference between these connections?Computer Science To answer this question, you may need to write a small program. Consider the following case: current cwnd value is 1000 bytes and 1 MSS is 10 bytes (=1 TCP packet carries 10 bytes of payload). With the basic formula, after 1 RTT, the congestion window would be updated to 1010 bytes (1000 + 10). What would be the value of window if ACK clocking is used? It would be a non-integer number, so give value including only two digits after comma

Assume that the web page consists of N = 20 inline objects each of size S2 = 100 KB. Assume that the round-trip time to the web server is T = 100 ms and the bottleneck capacity is C = 10 Mbps. Ignore any packetization delays and header overhead.a. Assuming non-persistent HTTP is used with a single TCP connection, how long does it take to download the web page?b. Assuming non-persistent HTTP is used with 4 parallel TCP connections, how long does it take to download the web page?c. Assuming pipelined, persistent HTTP is used, how long does it take to download the web page? ”Pipelined” means requests for multiple objects can be sent back-to-back on the same connection.d. Assuming non-pipelined, persistent HTTP with 2 parallel TCP connections is used, how long does it take to download the web page? Assume that the 2 parallel connections equally share the total available bandwidth C.
