Let a stream of packets from Host A and Host B using IPSec. Then a new SA will be established for each packet sent in the stream.True or False.

Using tcpdump,read the packets from tcpdump.pcap and filter packets to include ip address 184.107.41.72 and port 80 only. Write these packets to a new file and md5sum that file. what is the md5sum shown?

Consider sending a large file of F bits from Host A to Host B. There are three links (and two switches) between A and B, and the links are uncongested (that is, no queuing delays). Host A segments the file into segments of S bits each and adds 80 bits of header to each segment, forming packets of L=80+ S bits. Each link has a transmission rate of R bps. Find the value of S that minimizes the delay of moving the file from Host A to Host B. Disregard propagation delay.

What does it mean when an HTTP query has a header field of "Connection: keep-alive"? a. The client can keep the TCP connection open for future requests/responses if this is supported by the server. O b. Use UDP for additional connections to the server. c. Continually send an object from the server to the client until the client has acknowledged receipt of the requested object. O d. Use the QUIC protocol for this connection.
