Consider the network shown below with the given link costs. Initially each node knows only its neighbors and cost of the links to them. The distance-vector routing (DV) algorithm is used to compute the least cost paths for all source-destination pairs. The network connectivity and link costs are stable. The routing updates occur in rounds. In an update round, each node updates all of its neighbors with the nodes it currently knows after the previous round and the distances to them. Match each of the statements or questions in the left column with the most appropriate response from the right column. V -W 9

Computer Network LAN Network Topology Image. the image below Use the image as a reference, if the values are A, B, C and D (3rd octet) with the following conditions: Value A = 29 Value B = A + 1 Value C = A + 2 Value D = A + 3 x1, y1, z1 are the interfaces for the router gateway, while x2, x3, y2, y3, z2, z3 are for the router interface a.

With the Routing Table that you have specified in point a, which path will PC1B take when communicating with PC2B and PC3B c. In theory there is a routing table for Network Address 0.0.0.0 with a Subnet Mask of 0.0.0.0, explain the function of this routing table?
Consider a Wi-Fi access point (AP) servicing downstream traffic using a CSMA-like (random access) MAC protocol. Assume that the inter-arrival time between any two consecutive frames arriving at the AP is exponentially distributed with mean 1/A=0.5 minute. When a frame arriving to the AP finds the AP busy serving other frames that arrived ahead of it, the frame is queued. When the frame reaches the head of the queue, it then gets served/transmitted using the random access protocol. Assume that the time it takes to service one frame is exponentially distributed with mean 1/μ = 1 minute. Let T; denote the amount of time frame i spends in the Wi-Fi network; that is, T, consists of the queueing delay plus the service/transmission delay. In this problem, we are interested in estimating, using simulations, the parameter of interest 0 = E[W] where W = T₁+T₂+...+T₂ and p = 10. A simulation run would then consist of (1) simulating the system for some time until the first p frames are serviced,…
The CSM Tech organization has a substantial web presence with several publicly accessible web and application servers. You have DNS servers that handle Internet queries for all your publicly accessible resources. However, after doing some statistical analysis on your public DNS servers, you find that your servers are handling recursive lookups for clients that are not within your organization. Your public DNS servers should handle recursive queries only for your internal clients, but the servers should handle iterative (nonrecursive) queries from external sources. What do you recommend? What are the commands needed to implement the solution?

In Python, implement a hashing table data structure of size 20, which can cope with collisions. Thus, you must implement the closed collision system in its three modes: Linear scanQuadratic scanDouble hashing scan. For halt use halt(k)= (k mod (m - 1)) + 1, where m is the size of the table. The data to be managed are students from a certain university who have a 5-digit registration number and it is unique. In addition, the student has a name, age and address. Create a .txt file with 10 students (one for each line) and have them loaded into your program. Build a menu of options where you can: - Find a student and print his data if found and position in the table. Otherwise print a "Not Found" message.

For this option, that only allows entering the 5-digit license plate and that random data is automatically generated for the name, age and address. Return the position where it was entered and if it is not possible to enter it, print a message that explains why the entry was not obtained.
You develop a system composed of many components and would like to minimise the average distance in terms of the number of links between any two components. which network types should you consider for organising the structure of your system, where the components are accepted as the nodes of the network? Mark all correct answers. regular lattice scale free network small world network with a carefully chosen proportion of randomly rewired edges random network There are more than one correct answer. Please explain why.
You're working on a procedure that will connect a node to a doubly connected set. The machine in which this operation will be run is prone to hardware faults on a regular basis. The list that your software must keep is extremely important. As if the computer crashes in the midst of performing the process, the software must maintain the list's accuracy. Provide the actual statements you'll need to update the list in your protocol. (There should be no more than a dozen statements on the list.) After each command, explain the impact of a system malfunction. Describe how you can change this protocol to recover the simple list's credibility in the event of a system breakdown.
C PROGRAMMING you are to write a TCP/IP server that can build up a graph of a network ofnetworks (using the supplied graph library and implementation of Dijkstra’s algorithm) and thenquery that graph to find out which link between two networks should be used as the next hop tosend a packet of data from one network to another within the network of networks (using thesupplied implementation of Dijkstra’s algorithm). using the following program as a start point: /* * NetworkServer.c * ProgrammingPortfolio Skeleton * */ /* You will need to include these header files to be able to implement the TCP/IP functions */#include <stdio.h>#include <stdlib.h>#include <string.h>#include <sys/types.h>#include <netinet/in.h>#include <netdb.h>#include <fcntl.h>#include <unistd.h>#include <errno.h>#include <sys/socket.h> /* You will also need to add #include for your graph library header files */ int main(int argc, const char * argv[]){ int…
An input string S of length N is transferred through the network using a special protocol. The protocol can send the string through a series of operations. In one operation, we can choose a lowercase english alphabet and do one of the following: Transfer 1 copy of C through the network. Transfer 2 copies of C through the network. Each of the above transfers take 1 unit of time. Find the minimum time in which we can transfer the entire string S through the network. Note: Please Answer Python only Input 1 5 cbcdc Output 5
