- 4. [Socket] What is a socket? Suppose a process in Host C has a UDP socket with port number6789. Suppose both Host A and Host B send a UDP segment to Host C with destination portnumber 6789. Will both segments be directed to the same socket at Host C? If so, how will theprocess at Host C know that these two segments originated from two different hosts? 5. [Demultiplex] Define multiplexing and demultiplexing. Briefly explain how TCP demultiplexing isdifferent than UDP demultiplexing. 6. [rdt] Consider a reliable data transfer protocol that uses only negative acknowledgments.Suppose the sender sends data only infrequently. Would a NAK-only protocol be preferable to aprotocol that uses ACKs? Why? Now suppose the sender has a lot of data to send and the end-to-end connection experiences few losses. In this second case, would a NAK-only protocol bepreferable to a protocol that uses ACKs? Why?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.Subnetting IP Networks - Given the address block 192.168.30.0/24, create an IP addressing scheme that would allow for 2 subnets with 126 host IP addresses per subnet. Compute for the first two subnets only
- Q3: Assume the given class C IP Address, 192.168.0.X, where; X is the last two digits of your arid number (For example a student having 19-arid-121 will use ASCII of 21 as X . Apply subnetting of 3 bits and write about: a. Network and Broadcast IP of the subnet in which this IP 192.168.0.X belongs to b. First and last valid IP of the subnet in which this IP 192.168.0.X belongs to. c. Sub-net mask of this IP after subnetting.consider 3 hosts (A , B and C) where A is running 3-TCP process, B has 1-TCP process and C is running 2-UDP process all process are trying to connect to a web server to download a file . How many new socket(s) will be created at the server side? Explain why?52- A network for a local office requires 4 LAN subnets as follows: · Subnet A - North Office with 31 hosts; · Subnet B - East Office with 15 hosts; and · Subnet C - South Office with 7 hosts. · Subnet D – West Office with 4 hosts. Given the IP Address 192.168.15.0 /24 and above described network requirements: 1. Design an optimal address scheme using Variable Length Subnet Mask (VLSM) method; What will be the subnet mask of Subnet A? Select one: A. 255.255.255.192 B. 255.255.128.255 C. 255.255.255.128 D. 255.255.192.192 E. 255.255.192.0
- Scenario There is design1.csv file attached to this router interfaces ip_on_interfaces R1 s1, fa1 10.0.2.1, 192.168.1.3 R2 s0 10.0.2.2, R3 s0, Fa0, s1 10.0.2.3, 192.168.4.3, 192.168.5.5 R4 s0, s2 10.0.2.4, 192.168.8.8, Write a Python script to generate configuration files automatically for each router in the first column. Example, for router R1, the configuration file name should be “r1_config.cfg” and so on. The configuration commands for router R1 are as follows, the other routers’ commands are similar, according to the design file: #configure terminal # hostname R1 # enable secret Pas$w0rD # interface s1 # ip address 10.0.2.1 # no shutdown # interface fa0/1 # ip address 192.168.1.3 # no shutdown # endCan you find any problem with the following statement? "In a network (let Network Address 101.10.0.0/25 is using for 120 hosts network) a station is configured with an address of 10.0.0.11 Mask of 255.255.254.0 and a gateway address of 10.10.0.39."21.) Consider the following configuration. Computer “A” IP address: 172.16.100.100 Subnet mask: 255.255.0.0 Computer “B” IP address: 172.16.200.200 Subnet mask: /16 What should be done to allow these computers to send and receive data to and from each other? A.) Nothing needs to be changed. B.) Delete the subnet mask from each computer. C.) A router must be configured and placed between the two computers. D.) Remove the hub between the two computers and replace it with a switch.
- In this programming assignment, you will implement a decentralized peer-to-peer network architec-ture (P2P), including the basic implementation of the BitTorrent protocol (BTP). General P2P architec-tures can be classified into centralized and decentralized, In P2P centralized architectures, new peers senda request to the Traker (normally done via HTTP) requesting a list containing all the IP addresses ofthe peers that are already connected to the P2P network sharing the same file. The tracker then, replieswith a response containing such list. In P2P decentralized architecture, each peer is also a Traker, and itcan share only limited resources because it only sees the partial network. On the other hand, P2P decen-tralized networks avoid single point of failure since they do not depend of centralized trackers. Examplesof P2P applications that are/were implementing centralizing architectures are Nasper, the Berkeley OpenNetwork Infrastructure (BOINC) and some versions of BitTorrent.…Write aprogram to find the ip dotted decimal notation conversion from decimal to binary,octal and hexadecimal and vice versa also find the result of NOT and AND operation of ipv4 adresses. a. 114.34.2.8 Find the result of each operation: a.
