LAB 8 CREATE VLANS USING IPV4 IN PACKET TRACER

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. 1) UDP Echo Server Receiving and Displaying Messages: The UDP Echo server should be able toreceive messages sent by clients. For each…

Task2: In packet switching technology the packet size is an import parameter when it comes to efficiency and reducing the network latency. Let us assume a network which consists of a sender host and a receiver host at nh hops faraway from each other's (nh-1 routers R). s>R>R> ...>S. If we assume that all links have a bit-rate B bps and originally the message to be send from the sender to the receiver is of size L bits. 1) Give the formula to compute the network latency if we assume circuit switching (switching time per switch is s seconds). 2) Same as in 1) but we assume packet switching with packet size p bits. 3) From 2) drive the best packet size p which give the best performance (minimum network latency). Hint. One way to find out the minimum of a function f is to find its derivative f'(0). 4) Verify your result by providing prove example.

1. Build a Router network which has three Generic Routers and totally of Six networks in it. From each Router the required switch shall be connected through Fast Ethernet port and the switch is connected to two users. On the whole there are '6' networks in the configuration. Along with the network diagram do the packet transfer in simulation mode and write results for three different combinations.

Using packet tracer, implement a network that has the following components: 1- At least five routers 2- At least 7 subnets 3- At least 12 PCs 4- At least 4 switches 5- Use RIP routing protocol To assign IP addresses of the routers and PCs, use the IP address from your ID as follows Assume your id is 118zyxw, Consider the numbers z, y, x and w as deciemal You have the subnet 118.0.0.0/24 If your ID is 1181234 then the IP is 118.0.0.0/24 Use this subnet to get at least 7 subnets.

An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most signi cant bits are used as a network ID, and the 16 least signi cant bits are used as a host ID. However, the host ID cannot be all 0's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network?

Course name: Networking  Question Type:  MCQ An HTTP client requests a web page with 12 (additional) objects in it. The client can only figure out that the page contains 12 objects after downloading the first object (i.e., the web page HTML content). Assume that each packet exchange with the server incurs an RTT of delay and that other processing delays (e.g., parsing the web page) are negligible.  Suppose the client uses 5 persistent connections. How many RTTs elapse until the page and its objects are fully downloaded? A: 8 B: 14 C: 4 D: 5

Refer to the network figure above, showing two Ethernet Subnets connected through an IP Router, answer the following question 1-5. The devices in each subnet are connected locally to each other through layer two intermediate devices such as Ethernet switch and ethernet hub. For each device in the subnets, both its Internet Protocol (IP )address and its MAC address (also called the Physical address or the Ethernet address are shown. The subnet mask used by all devices is 255.255.255.240 (which is the same as the prefix length “/28”). 1. If Client #1 wants to send a broadcast packet to all the devices on the left subnet (containing client #1, client #2, client #3) what destination IP address should be used? (Mention in both binary and decimal format.)  2. What is the first and last assignable IP address for the left subnet above (containing client #1 and #3)? (Mention in both binary and decimal format.)

Consider the following virtual circuit network with three reserved virtual circuits: уC1: H1, А, С, Е, Н2 VC2: H3, A, F, D, H4 ус3: НЗ, А, F, D, E, H2 Host H4 Host H3 Нost H2 Host H1 Draw the routing table of router D and the routing table of router C. *you may design a table using the HTML editor or write the content of routing table record by record (record per line).

Suppose we have a web page which contains 10 objects including: a html main file, 8 jpg image, and a .mp3 background music. For simplicity, assume each of the 10 objects has a size of 4 Kbits and that each object can be completely transferred in one TCP packet. Furthermore, assume the round-trip time between the server and client is RTT= 250 ms, and the download rate is 1 Mbps. What will be the time it takes to complete transferring the web page running in the non-persistent mode? Total delay = ms

sWin an international IT solutions company, is launching 11 new branches in a new country where they currently have no existing branches.  The sWin CIO has asked that each subnet should host at least 2000 devices. sWin has obtained a network address of 10.11.0.0/17.This address needs to be subnetted further and the CIO has decided that the internal subnet mask will be /21 The company’s subnet plan allows for: Router Pool: 2 router interfaces for each subnet – the last 2 IP addresses from each subnet. Managed Network Device Pool: The first 64 IP addresses are reserved for switches and other network devices Server Pool: The first 64 IP addresses following the Managed Network Device Pool are reserved for servers. Workstation Static Pool: The first 16 IP addresses following the Server Pool are reserved for Workstations that require static IP addresses. Workstation DHCP Pool: The remaining IP addresses are reserved for automatic IP configuration. You have been asked to use subnet 10 for…

An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most significant bits are used as a network ID, and the 16 least significant bits are used as a host ID. However, the host ID cannot be all 0's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network?

Computer Science Networks and should be done in C language.   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 threads

In IPV4, consider sending a 4,000 byte datagram (20 bytes of IP header) into a link that has an MTU of 1,500 bytes. The datagram will be allocated to fragments, and the offset value of the third segment is 3, 370 3, 185 4, 185 4, 370

Registration Number: 193046 Consider a network with 3 hosts and a NAT router. Suppose that the network address of the home network is 192.168.NNN/24, where NNN are the last 3 digits of your Reg#. For example, if your Reg# is BSE193046, NNN = 046 and therefore the network address wil be 192168.46/24. (If NNN>255, consider NNN=254) (a) Assign any public IP address to NAT router’s outgoing interface. (b) Assign IP addresses to all 3 hosts and local interface of the NAT router in the home network. (

Given the following topology of a network, the router Node 3 connects the two subnets together: Nodes 1 and 2 are 'inside' of the subnet neta, Nodes 4 and 5 are 'outside' of neta and Node 3 with a firewall is the gateway of neta. The two networks have the prefix 192.168 as the first two octets in their IP addresses, e.g, Node 1 has IP address 192.168.1.11. eth1: 1.11 eth1: 2.21 1 2 eth1: 1.12 neta eth 1: 1.1 3 eth2: 2.1 netb 4 5 eth1: 2.22 (i) Suppose in the firewall on Node 3 the default policy is ACCEPT. Write packet filtering rules for the following goal. Suppose Node 5 hosts a web server supporting both HTTP and HTTPs. Set rules in Node 3 that prevents Node 2 from browsing any web pages at Node 5. Now change in Node3 the default policy as DROP and write packet filtering rules for the following goal. (ii) Allow all nodes in the subnet neta to browsing HTTP pages hosted at Node 5. (iii) Allow hosts in netb to SSH into Nodel.

Computer Networks - Internet Architecture & Application Layer Please answer the question   Someone suggested to use a local file called hosts.txt on each machine instead of DNS. Discuss the advantages (at least 2) and disadvantages (at least 2) of such suggestion. What is ‘saw-tooth’ behavior in TCP, and what is causing it?

A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number.Discuss about the different types of socket calls using in TCP &UDP.

Draw a network design that you think will be useful in the future for the industry that you have visited. Network should include the following requirements:  3 routers 4 switches 10 PCs 4 VLANs. Suitable IP addressing scheme in tabular form (assume as many hosts as necessary for each department). Indicate where do you use static routing, dynamic routing protocols (name the protocols, RIP, EIGRP, OSPF, etc.), Access Control List (ACL) as per the network preferences. Justify your choices.

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

In network administration, many admins will use a VLAN (Virtual Local Area Network) to create logical subnetworks. The advantages of this type of a setup is better confinement of broadcast domains, reduced broadcast traffic and more efficient maintenance of the network. The admin can group network nodes that are physically dispersed into similar broadcast domains for improved network traffic management. Configuration of VLANS on multiple switches can be very time consuming. Python scripts can help automate tasks reducing the need to physically go from switch to switch. Minimal configuration variables may include VLAN name, VLAN number, and Network device. The main.py template provides a list of 5 network switch names. The script will simulate the configuration of those 5 devices. Define the VLANSetup class in VLANSetup.py with a constructor to initialize a VLAN's information. The constructor should by default initialize the VLAN's name to "None" and the VLAN number to 0. Define the…
