In an internet networking environment, TCP/IP protocol suite performs different networking functions using the Open Systems Interconnections (OSI) reference model comprising of 7 different layers. Please explain the functionality of each OSI layer and identify how the OSI model and the TCP/IP Protocol suite are mapped with each other.
Describe the operation of a router at the network layer of the OSI model. What is its primary function, and how does it route data packets?
Explain the purpose of routers in the OSI model's Network layer. How do routers facilitate communication between different network segments and improve overall network performance?
A connectionless protocol, such as Ethernet, defines the route of a packet through source and destination addresses. However, a connection-oriented protocol, such as ATM, defines the route of a cell through virtual connection identifiers (VPIs and VCIs). Could you explain this statement?
WireShark: The goal of this assignment is to explore the network packets associated with several typical online activities. You will have the chance to analyze bit-by-bit the flows associated with these services and evaluate different application and protocol parameters across the entire TCP/IP stack including Data Link Layer/Medium Access Control (L2), Network Layer (a.k.a. IP or L3), Transport Layer and Application Layer. To carry out this analysis, you will use Wireshark. Part of finishing this assignment will be learning how to use Wireshark effectively. While Wireshark allows you to capture packets on a network interface it can also be used to read previously collected packet traces. Make sure to show the full steps and screenshots of capturing network packets on Wireshark. Attached is the image of the Wireshark trace that needs to be analyzed.
How does a router function at the Network layer of the OSI model, and what is its primary purpose?
Many applications employ TCP at the transport layer and IP at the network layer as a common protocol stack. The ICMP protocol is also used to notify difficulties that IP encounters. a. The IP protocol offers a service known as "best effort." Describe the flow control services provided by the IP protocol and perhaps the ICMP protocol (ensuring the sender does not overwhelm the receiver). b. Describe the service TCP delivers in terms of flow control and explain the strategies it employs to compensate for IP's shortcomings.
Explain how a router functions within the OSI model. What layer does it primarily operate in, and how does it facilitate the routing of data between different networks?
[ ] As the data packet moves from the lower to the upper layers, headers are added. [ ] Every network device implements the transport layer. [ ] In the Ring topology, each computer acts as repeater make error detection and boosts the signal before sending it on. [ ] In bus topology network media is inexpensive and easy to work with, so it is easier to trouble shoot than other topology. [ ] Error control only detects errors [ ] Ethernet is a LAN so it is placed in the second layer of the OSI reference model. [ ] UDP provides connectionless service and delivers packets quickly. In case of packet loss, UDP does not provide retransmission. [ ] UDP is the preferred over TCP for transferring a real-time voice over IP networks. [ ] In a bus topology, each station on the network is connected to two other stations, forming a loop or ring. [ ] IEEE international Telecommunication Union for creating protocols of internet. [ ] TCP protocol is slower than UDP?
True or False: [ ] Routing decision is always required for every packet of a message at each node in packet switched network. [ ] In OSI model data link layer provides for the reliable transfer of information across the physical link; sends blocks (frames) with the necessary synchronization, error control, and flow control [ ] Because the boundaries between layer are well defined change in standard in one layer effect already existing software in another layer; this makes it difficult to introduce new standard
True or False In Open Flow the control plane stays on the device whereas the data plane moves to the SDN controllers. NAT table stores original source address and port, and NAT address and port pairs. ISPs connecting 100s of households use NAT to save on IP addresses. Switch routers in Open Flow are connected to the SDN controllers using the Open Flow Interface The connection between Open Flow switch routers and SDN controllers are protected using SSL/TLS Switch routers in SDN can communicate with other switch routers to create and maintain routing tables
