- 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.Subnetting a Class B Address: You are responsible for subnetting the network ID of 220.100.10.0 into four subnets. Take some paper and walk through your binary work of subnetting this class C network into four subnets. Once you have calculated your answers, fill in the following table.MC9: In wireless LAN communication, MACA is widely used. In this protocol, in order to avoid collision, a sender can send sender is granted the privilege to send a frame to the receiver only after it receives request signal to a receiver.

- 4 LANS are connected to a router (R1) with each LAN compares of several hosts connected to a switch. Each LAN cotains the following number of hosts (end devices and the gateway interface), • LANI à 30 Hosts • LAN2 à 15 Hosts • LAN3 à 20 Hosts • LAN4 à 3 Hosts You have received the address space 200.16.1.0/24. Use the address space to create a subnetting scheme of four subnets with equal size in a way to accommodate the number of hosts required. Consider the following points in your answer, / Explain the procedure of your subnetting scheme / Highlight the suitable prefix and the subnet mask / Highlight the number of wasted hosts in each subnet after determining the most suitable prefix / Use the table below to provide the subnet details for each LAN Subnet Address First Host address Last Host address Broadcast address 1 LANI 2 LAN2 3 LAN3 4 LAN4IPV4 is a Connection oriented Protocol. * False True Broadcast is the process of sending a packet from one host to a selected group of hosts. * False True The prefix length is the number of bits in the address that gives the Host portion. " False True The metric is used to decide which route appears on the routing table. * True False The throughput value is greater than The Bandwidth Value. * True False O O O O• IPV6 addresses use 128 bits to represent an address which includes bits to be used for subnetting. The second half of the address (least significant 64 bits) is always used for hosts only. Therefore, there is no compromise if we subnet the network. Use the Figure below to Create five subnets using route prefix 2001:db:acad::/48 (1 Marks) Routing Prefix Subnet ID Interface ID 48 Bits 16 Bits 64 Bits
- Assume a client is connected to the server and has already received an HTML webpage. It reads the webpage, and it now needs to get 3 new files, File A is 5 MB file B is 1 MB and file C is 1 KB. The client requests the files in the order A B C. The link has an RTT (round trip time) of 0.5 seconds and a bandwidth of 8 Mb/s(Megabits per second) (or 1 Megabyte per second). The client can reuse the open connection if the protocol allows it to. For all parts of this problem ignore header sizes, and start the timer when the client sends How long does it take to get file C under HTTP 0? How long does it take to get file C under HTTP 1 (assume the browser does not support pipeling)? How long does it take to get file C under HTTP 2 assuming a frame size of 1 KB and no server push? What event would make HTTP 3 faster than HTTP 2 for this use case (ignore TLS)?44- An organization currently requires 40 hosts for its sales department. Given the IP Address 194.12.1.0 /24, design an optimal address scheme usingTradition Subnetting method, which will enable the connection of the sales department’s 40 hosts in one subnet and uses the remaining subnets for other departments’ hosts in the future.
