There are four routers. Each of the four different types of routers With the installation of a new link to connect routers A and C, does router A need to recompute its distance vector in response to the inclusion of router B and D into the network? RIP runs on the routers and the DV (distance vector) algorithm is the routing technique used by RIP.
0. AS1 has the following routing table, draw the network of AS’s that these paths imply: prefix path P1 AS2 P2 AS4 AS5 AS3 P1 AS4 AS2 P2 AS5 AS3 P1 AS5 AS2 Assuming AS 1 accepted all the paths advertised to it, what paths does AS4 advertise to AS1? What AS is P1 in? What about P2? AS5 no longer wants to forward packets destined for prefix P1 on behalf of AS1, but it is ok forwarding prefix P2, how would it change the paths it advertises to AS1? If AS1 sends a packet to AS4 destined for P1, what path will it take? How do we know AS4 won’t forward it back to AS1? If AS1 gets the following advertisement from AS4, P1 AS4 AS1 AS2 how would it update its table? Why?

NOTE: I would appreciate it if the solutions of the paths were hand-drawn so I can visualize it better.
In packet matching, one Echo packet may be the response for three request packets (Pattern: S1, S2, S3, E1), which of the following is ideal to represent the length of the connection chain? Question options: The average RTT of the three packets RTT betwee E1 and S1 RTT betwee E1 and S2 RTT betwee E1 and S3 The following figure shows the RTTs of all the packets collected from the beginning to the end of a connection chain, where Y axis represents the value of RTTs, and X axis represents the number of Send packets. How many hosts are compromised from the detecting host (also called sensor, count this host) in this case? Question options: 2 4 6 7
One proposed solution that allowed mobile users to maintain their IP addresses as they movedamong foreign networks was to have a foreign network advertise a highly specific route to themobile user and use the existing routing infrastructure to propagate this information throughoutthe network. We identified scalability as one concern. Suppose that when a mobile user movesfrom one network to another, the new foreign network advertises a specific route to the mobileuser, and the old foreign network withdraws its route. Consider how routing informationpropagates in a distance-vector algorithm (particularly for the case of inter-domain routing amongnetworks that span the globe). a) Will other routers be able to route datagrams immediately to the new foreign network assoon as the foreign network begins advertising its route? Why? b) Is it possible for different routers to believe that different foreign networks contain themobile user? Why? c) Discuss the timescale over which other routers in…
In an Internet that interconnects a set of nodes through a set of links, the calculation of the Jitter is something related to the ______: select one a. destination node only b. links c. source and routing nodes d. both source and destination nodes e. routing nodes f. source node only g. None of the mentioned choices is correct h. routing nodes and destination
It has a total of four routers. Every single one of the four distinct kinds of routers Does router A need to recompute its distance vector as a result of the addition of routers B and D to the network as a result of the construction of a new link that connects routers A and C? The DV (distance vector) algorithm is the routing mechanism that is employed by the RIP protocol, which is executed on the routers.
Consider a network with 4 links between two hosts where the maximum allowable packet size is 1000 bits; each link has a transmission rate of 2000 bits per second, except the second link has a transmission rate of 1000 bits per second. How long does it take to send 6000 bits from one host to the other? You may ignore propogation delay, assume there is no other traffic on the network, and assume that no routers drop packets due to queue length. Round your answer to two decimal places.
Suppose we have two topologies of computers in two rooms. One room has 5 computers connected with mesh topology and the other room has 3 computers connected with star topology. Calculate how many links you will need for each of the topologies. If you were to choose between these two topologies for a more secure network which onewill you prefer and why?
There are 4 routers Router A, B, C and D Router B and D are connected in a network system, RIP is the routing protocol running on the routers, DV(distance vector) algorithm is the routing algorithm for RIP, a new link is added to the system to conect router A and C, will this addition trigger router A to re-compute its DV?
49- 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. What will be the last host address of 4th subnet? Select one: A. 194.12.1.254 B. 194.12.1.192 C. 194.12.1.253 D. 194.12.1.255
Consider a node called A that sends packets to an adjacent node called B. To control the packet flow to node B, node A employs a credit manager scheme in which parameters C=3(credits), C_max=4(credits) and \tao=6(msec), respectively. node A has an infinite buffer to temporarily store packets. When a packet arrives at node A, node A stores the packet at the bottom of the buffer. Node A also has a single server (transmitter). As soon as the server becomes idle, the server picks up a packet at the head of the buffer, if any, and serves the packet for packet transmission time T_p as far as there remains a credit. (The packet transmission time T_p = 4 (msec).) We observed the arrival times of the first 12 packets, denoted by aA(1)⋯A(12), which were as follows: n A(n) 1 0.5 msec 2 1.0 3 1.5 4 2.0 5 4.5 6 5.5 7 6.5 8 12.5 9 13.0 10 13.5 11 14.0 12 14.6 1. Let R(n) denote the departure time of the n th packet from the buffer for n∈{1,2,...}. Find R(n) for…
