Step by step
Solved in 2 steps
- ii) Describe the four IP abstraction levels in TCP. ii) Explain a fictitious scenario in which two computers share a video file via an open FTP connection with a weak TCP three-way handshake.2. Describe the four IP abstraction layers that make up TCP. ii) Describe a hypothetical situation in which two computer machines are sharing a video file via an unprotected ftp connection with a vulnerable TCP three-way handshake.ii) Describe the four abstraction levels of TCP and IP.ii) Describe a hypothetical circumstance in which two different computer computers are collaborating to share a video file by means of an unsecured ftp connection with a potentially insecure TCP three-way handshake.
- 3.3 Contrast TCP and UDP. As a software architect, provide two applications where you would choose to use TCP instead of UDP.Assignment 5: Both TCP and UDP are widely used IP transfer layer protocols. For applications requiring reliable transfers, TCP is generally preferred, while applications that value throughput more than reliability are best served using UDP. Most TCP/IP stacks provide both protocols, so the application can use whichever transfer protocol is more appropriate, even changing from one to the other as desired. Rather than rely solely on TCP, the network system developer might want to investigate the trade-offs related to use of UDP. Based upon the analysis list out why Some TCP/IP Applications Use UDP?ii)Detail the four abstraction layers that make up TCP/IP. ii) Provide a scenario in which two computers share a video file via an unencrypted ftp connection using a weak TCP three-way handshake.
- 3.5-4 TCP sequence numbers and ACKs (2). Suppose that as shown in the figure below, a TCP sender is sending segments with 100 bytes of payload. The TCP sender sends five segments with sequence numbers 100, 200, 300, 400, and 500. Suppose that the segment with sequence number 300 is lost. The TCP receiver will buffer correctly-received but not-yet-in-order segments for later delivery to the application layer (once missing segments are later received).Provide an overview of the four abstraction layers that make up TCP/IP. ii) Speculate on a scenario where two computers are transferring a video file via an unencrypted ftp connection using a weak TCP three-way handshake.3 A) Give a one sentence description of the primary purpose of the Transport layer. B) Give a one sentence description of the primary purpose of the Application layer. C) A TCP sender process has sent four (4) segments and received acknowledgements for the first two (2). The third segment times out. What steps does the TCP process take after this occurrence?
- 29. The following figure shows the IP addresses of t he interfaces connecting routers R1, R2, and R3. A static route is configured on R1 using the com mand ip route-static 10.0.23.0 24 10.0.13.3, so th at the IP address 10.0.23.3 of GE0/0/2 on R3 can be pinged from R1. To prevent the communicati on failure between R1 and R3 in the event of the link between them becoming faulty, a backup lin k to 10.0.23.3 needs to be configured. Which of t he following commands should be used to confi gure the backup link? A. [R1] ip route-static 10.0.23.0 24 10.0.12.2 preference 40 B. [R1] ip route-static 10.0.23.0 24 10.0.12.2 preference 80 C. [R1] ip route-static 10.0.23.0 24 10.0.12.2 preference 40 [R3] ip route-static 10.0.12.0 24 10.0.23.2 D. [R1] ip route-static 10.0.23.0 24 10.0.12.2 preference 80 [R3] ip route-static 10.0.12.0 24 10.0.23.2The four TCP/IP abstraction layers are as follows; please describe them in detail.TCP sockets handle data sent as a byte stream, but UDP sockets are aware of message boundaries.What are the advantages and disadvantages of a byte-oriented API versus an AP that recognises and preserves application-defined message boundaries?
