You can assume that the two networks are both connected to the same router. You must include a detailed explanation of the following: Physical layer Data link layer Network layer Transport layer MAC address IP address

Assume that Computer A, which is connected through an Ethernet cable to the Switch S1, is just powered on. The user opens a browser and then types a website address to receive the website from the Server (as shown in Figure 1). Write down all the important protocols that come into play by the time the first frame containing HTTP request reaches R1. (Note: Before HTTP frame, other frames have already been sent by other protocol(s).) Write down all the protocols with reference to the TCP Model as follows? Application Layer: Transport Layer: Internet Layer: Link Layer:
From the above scenario, RIP and internal EIGRP routing protocols were configured on thesame router. Identify and explain which one of the two routing protocols will be selected bythe network and why.
The path of a packet is defined by source and destination addresses in a connectionless system like Ethernet.A connection-oriented protocol, such as ATM, however, uses virtual connection identifiers to specify a cell's route (VPIs and VCIs). Could you please elaborate on this statement?
question 2 : Given the following topology. By calculating a network address yourself(Calculation Process: First three digit of your ID.fourth and fifth Digit of your ID.last Two Digit of your ID.0/choose a suitable subnet mask). Now perform a classless subnetting (VLSM) and show the results. ( You can use a table with ROW as a Network Address and COLUMN for representing the Number of hosts, Subnet Mask, etc. my Id : 2020000010051
When the FTP client is connected to the FTP server, the Transport Layer protocol TCP created a reliable session. TCP is routinely used during a session to control datagram delivery, verify datagram arrival, and manage window size. For each exchange of data between the FTP client and FTP server, a new TCP session is started as shown in this WireShark screenshot: 1.Identify Three-way handshake packets and write them here? 2.Identify and list the graceful termination of communication between FTP client and server? 3. what is the port number of FTP protocol? 4. Identify the source and distention IP addresses?
Assume all the links in the Internet provide reliable delivery service--select the answer which best explains why TCP's reliable delivery service would still be required. 1. TCP's reliable delivery service is not needed in this case because the application in the host devices will resend messages if the network layer discards IP datagrams. 2. IP provides an unreliable delivery service and will discard datagrams for various reasons. 3. TCP's reliable delivery service is not needed in this case because each link along the total path guarantees frame delivery to the next device. 4. TCP's reliable delivery service would not be needed in this case because IP provides reliable datagram delivery with ACKs, NAKs, and retransmission.
Suppose two hosts are connected with each other by means of a 100-Mbps link, and assume the round-trip time between them is 1 ms. What is the minimum TCP window size that would let TCP achieve the maximum possible throughput between these two hosts? (Note: Assume no overhead.)
Assume that you have two computers and a router (default gateway) that have the following TCP/IP configuration and that Computer A wants to send data to Computer E. Match the addresses that will be used in the IP packet and the ethernet frame sent from Computer A. Computer A IP address: 178.23.43.12 Netmask: 255.255.0.0 Default gateway address: 178.23.17.1 MAC Address: 34:2A:C6:C6:55:C3 Computer E IP address: 178.23.54.23 Netmask: 255.255.0.0 Default gateway address: 178.23.10.1 MAC Address: 34:2A:C6:76:3E:12 Default Gateway MAC Address: 65:D3:C9:11:C5:99 Items to Match: IP packet Source IP address: IP packet Destination IP address: Ethernet frame Source MAC address Ethernet frame Destination MAC address Possible Values: 178.23.17.1 178.23.10.1 178.23.43.12 178.23.54.23 34:2A:C6:C6:55:C3 65:D3:C9:11:C5:99 34:2A:C6:76:3E:12
Detailed assessment involves scanning all 65,536 TCP and SCTP ports for each IP address withinscope, along with testing of common UDP ports (to save time). I have yet to find a UDP servicerunning on a nonstandard port during testing, and so running a UDP scan with Nmap’s default serviceslist is sufficient
