Expert Solution & Answer
Chapter 9, Problem P16P
a)
Program Description Answer
The video that is streamed directly from web server to media player will use TCP as the underlying protocol.
Hence the given statement is “True”.
b)
Program Description Answer
The user is capable of changing the encoding in the middle of the session to change the payload type of the RTP stream.
Hence the given statement is “True”.
c)
Program Description Answer
The application that uses the RTP can use any port to send and receive through any port numbers.
Hence, the given statement is “False”.
d)
Program Description Answer
The session that has a separate audio and video stream for each sender, the audio and video streams uses different SSRC.
Hence, the statement is “False”.
e)
Program Description Answer
Per-hop behavior defines the difference in the performance among the classes of traffic present in the diffserv network.
Hence, the given statement is “True”.
f)
Program Description Answer
According to the example given in the text, Alice indicates that the message to receive the audio from the bob.
Hence the given statement is “False”.
g)
Program Description Answer
According to the example given in the text, Alice indicates that the message to receive the audio from the bob through the port 48753.
Hence the given statement is “False”.
h)
Program Description Answer
The messages between the SIP entities are transmitted through a default port number 5060.
Hence the given statement is “True”.
i)
Program Description Answer
The SIP registration process is made using the REGISTER. Registration is the first step for making VOIP (Voice Over Internet Protocol).
Hence the given statement is “True”.
j)
Program Description Answer
H.323 mandates the G.711 audio encoding and the given is not the requirement of the SIP.
Hence the given statement is “False”.

UDP Echo ApplicationA UDP Echo program is a simple network application that demonstrates the basicprinciples of UDP communication. In this program, a server listens for incoming UDPpackets from clients, and when it receives a packet, it echoes (sends back) the samepacket to the client. The client sends a message to the server, and the server returns thesame message. It's often used for testing network connectivity and understanding thefundamentals of UDP communication.
(Answer the following question using python)
Implement both the server and client components of this UDP Echo program whileadhering to the features outlined below. Please ensure that your implementation followsgood coding practices and provides clear prompts and feedback to the user, making ituser-friendly and robust. Please refer to the class example to guide your implementation.

- SMTP (Simple Mail Transfer Protocol) is the standard protocol for transferring mail between hosts. A TCP connection is set up between a user agent and a server program. The server listens on TCP port 25 for incoming connection requests. The user end of the connection is on a TCP port number above 1023. You have defined the packet filter rule set shown in the table below. These rules permit and/or deny inbound and outbound traffic between the user agent and the mail server. Describe the purpose of each packet filter rule in the table.

Create a UDP client and server program that not only is able to locally transfer files but it gives the client the ability to send multiple copies of the file to multiple servers. Once the server program is initiated, it waits until it receives client packets. It then reads and saves the payload of the packets. The client reads a file from the disk and sends it to each server over a UDP socket by breaking the file up into mtu-byte sized packets. Client needs to be concurrent in sending the packets to all of the servers using threadsarrow_forward
