- 59- 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.

Compute for the first two subnets only
- Answer the following: a) Rewrite the given IPv4 address using dotted-decimal notation and find the class. 01011110 10110000 01110101 00010101 b) Rewrite the given IPv4 address in binary representation and find the class.1-In a network based on the bus topology, the bus is a non-shareable resource for which the machines must compete in order to transmit messages. How is deadlock controlled in this context? 2-Using 32-bit Internet addresses was originally thought to provide ample room for expansion, but that conjecture is not proving to be accurate. IPV6 uses 128-bit addressing. Will that prove to be adequate? Justify your answer’ (for example, you might compare the number of possible addresses to the population of the world).Consider a web page whose base file is of size S1 = 10 KB. Assume that the web page consists of N = 20 inline objects each of size S2 = 100 KB. Assume that the round-trip time to the web server is T = 100 ms and the bottleneck capacity is C = 10 Mbps. Ignore any packetization delays and header overhead.a. Assuming non-persistent HTTP is used with a single TCP connection, how long does it take to download the web page?b. Assuming non-persistent HTTP is used with 4 parallel TCP connections, how long does it take to download the web page?c. Assuming pipelined, persistent HTTP is used, how long does it take to download the web page? ”Pipelined” means requests for multiple objects can be sent back-to-back on the same connection.d. Assuming non-pipelined, persistent HTTP with 2 parallel TCP connections is used, how long does it take to download the web page? Assume that the 2 parallel connections equally share the total available bandwidth C.
- 7.1 In IEEE 802.11, open system authentication is accomplished via a simple two-way communication. The client requests authentication, which includes the station ID, which is provided by the server (typically the MAC address). A successful or unsuccessful authentication response from the AP/router is received in response to the previous request from the client. For instance, if the client's MAC address has been expressly omitted from the AP/router setup, a failure may occur.a. What are the advantages of using this kind of authentication scheme?b. What are the security flaws in this authentication method and how may they be mitigated?57- 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 range of usable (assignable) host addresses in Subnet C? Select one: A. 192.168.15.64 to 192.168.15.128 B. 192.168.15.97 to 192.168.15.110 C. 192.168.15.140 to 192.168.15.191 D. 192.168.15.128 to 192.168.15.139 E. 192.168.15.193 to 192.168.15.25442. Though there are practical reasons why we don't complicate our lives this way in the real world, from a theoretical perspective we could borrow non-consecutive bits for subnetting. So, when borrowing the first host bit, the second host bit and the last two host bits (counting from the left of the host bit field) from 172.1.0.0 can you determine the following: g. 1,203rd useable host address?

Develop in java4. [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?
