q no 5: In the above network diagram, IP and MAC addresses are given for network nodes. Suppose Host1 (Shahid) sends a datagram to Host2 (Khalid). What IP and MAC addresses (source and destination) will be written in IP and Data link layer headers respectively, for the following intermediate points from Host1 to Host2? Host1 to Router1 (R1) Router1 to Router2 (R2) Router2 to Host2
An ISP provider has a network address of 10.10.0.0 with a subnet mask of 255.0.0.0. The company wants to create four sub-networks for the four customers A, B, C and D that would contain A has - 1024 hosts, B has 512 hosts and Chas 256 and D has 128 hosts respectively. Find the following: a. Find CIDR of an ISP provider and Subnet mask of ISP provider b) Find starting address and end address of customer A, Subnet mask and CIDR of A c) Find starting address and end address of Customer B, Subnet mask and CIDR of B d. Find starting address and end address of Customer C, Subnet mask and CIDR of C e. Find starting address and end address of Customer D, Subnet mask and CIDR of C f) Find remaining addresses an ISP provider hold after the allocation.
Answer the questions below with reference to Data Link Layer (max 250 words): i) A local Area Network (LAN) Medium Access Control (MAC) protocol aims to achieve fair and efficient access to a LAN transmission medium. Characterise the distinction between authorisation based (“taking turns”) and contention based (random access) MAC layer protocols and discuss the suitability of each protocol in light traffic and heavy traffic networks in terms of fairness and efficiency of access. ii) In CSMA/CD, after the fifth collision, what is the probability that a node chooses k=4. The result k=4 corresponds to a delay of how many seconds on a 10Mbps Ethernet?
Question 3: An educational institution has an access network whose operating parameters are as follows: access link to originating servers’ rate: 15.4 Mbps RTT from institutional router to server: 2 sec Web object size: 100K bits Average request rate from browsers to origin servers: 150/sec average data rate to browsers: 45.0 Mbps Institutional access network speed: 1Gbps. 3.1. You are requested to provide the performance of the institutional access network in terms of• LAN utilization• Access link utilization• End-to-end delay from the access network to the origin servers. Note: Assume that the requests from the web client to the originating web servers are of the order of 2GB of data on average. 3.2. Assuming that the institution would like to install a web cache in its access network with a cache hit rate is 0.65, you are asked to recompute the new performance of the access network in terms of:3.2.1.

Assign network addresses to each of these six subnets,with the following constraints: All addresses must be allocated from 212.10.8/23; Subnets A, B, and C should have enough addresses to support 120, 240, and 120 interfaces respectively. Of course, subnets D, E, and F should each be able to support two interfaces. For each subnet, the assignment should take the form of a.b.c.d/x or a.b.c.d/x - e.f.g.h/y. ----- Using your answer to the previous part, provide the forwarding tables (using longest prefix matching) for each of the three routers. You may use label R1A to denote the interface on router R1 that is part of subnet A and so on.

You are tasked with designing a network for a company that has offices in four locations: Kentucky, Ohio, Michigan, and Indiana. Each location will be represented by one router and an accompanying PC. The four routers will have point-to-point connections with one another. Design a subnetting plan for this network that meets the following requirements: ⚫ Use the Class C private network 192.168.1.0 for your point-to-point connections. These subnets will all have the same mask. When selecting one, consider the fact that these subnets only need two usable IP addresses; find the smallest mask that will support this. ⚫ Using the Class A private network 10.0.0.0, create a subnetting scheme that uses the least number of IP addresses possible for the following number of hosts in each location: 。 Kentucky: 500 o Ohio: 2000 o Michigan: 1000 o Indiana: 250 ⚫ When dividing the 10.0.0.0 block, please make sure you start from the location with the largest host count to the one with the…

If we have the network-ID of subnet 127.91.220.100 And as shown in the picture we need to plan network , Rt-A = 2100 hosts , Rt-B= 1000 hosts, Rt-C= 300 hosts, Rt-D = 600 hosts. NOTE: It is possible to allocate more than one subnet per interface. Create a table for each of the eight networks that contains the network-ID and subnet mask for the subnet/subnets in that network.
