Dst Addr AD Port 0 WO 3 Dst Addr ABUD Dst Addr BD Port 0 1 Port 1 A 0 3 B D 0 0 Dst Addr B D Dst Addr ACO D Port 0 1 Port 1 10 0 (a) Based on the forwarding tables, show how the switches forward a packet from

In this problem, you will be learning about selflearning Ethernet switches. First read the attached supplement on Ethernet switches and how they can selflearn. Now, consider the operation of a learning switch in the context of a network in which nodes labeled A through F are star connected into an Ethernet switch (see figure below). The switch

Considering Ethernet switches, what is the meaning of filtering and forwarding Please explain how a switch fills its forwarding table (selflearning process). Suppose a frame with destination address DDDDDDDDDDDD arrives at the switch on interface x. The switch indexes its table with the MAC address DDDDDDDDDDDD. What are the three possible actions

Create switch table(s) for a figure below. Assume the table is initially empty and you are sending data in the order (1) 1,2,3,4,5 (2) 5,4,3,2,1 and (3) 2,5,1,1,1 mentioned in the figure. Explain the process for switch table self learning and forwarding for your answers. 1 BC 5 BB C B 3 AA 4 AA A A Source A Dest A B 2 CCB

Consider the network below with six nodes, star-connected into an Ethernet switch. Suppose that A sends a frame to A', A replies to A, then B sends a message to B and B replies to B. Enter the values that are present in the switchs forwarding table after B-to-B frame is sent and received. Assumed that the table is initially empty and that entries

Consider an Ethernet LAN consisting of N nodes interconnected with a switch. Suppose the switchs forwarding table is initially empty. Suppose node A wants to TCP threeway handshake with node B, where both nodes are on the LAN. 1) Assuming this is the only traffic on the network, and there are no packet errors or loss, how many frames will be

List the elected root, the port selected by each bridge as the preferred path to the root, and the designate bridge elected by each LAN. b. Initially all bridges hold empty forwarding tables. Suppose

For the following graph G draw and label each of the spanning trees of G. a b d e

You are working with a startup company that wants to build a web system for scale. They traditionally had their server instances and had built their full-stack application in-house and hosted it on-premises. They are not sure whether a traditional VM-based cloud model is more appropriate for them or Serverless. They ask your opinion about moving

Given the following Btree, please answer following questions. 12113411411511 5377838586 1. (5 marks) What is the value of p for this Btree (Note that p is the order of a Btree) 2. (6 marks) Can you rebuild a taller Btree with the same value of p using the same set of searchkey values in the leaf nodes of the given tree If yes, show the steps by

Prove the following statement for any integers x and y If xy is odd, then x is even or y is even. Specify which proof method you have used.

Consider the following scenario using NAT (Network Address Translation). The public IP address and the private IP addresses are shown in the diagram. The NAT table already has the information as shown due to previous communications. WAN side addr 28.36.39.20, 3207 28.36.39.20, 3208 28.36.39.20, 3209 NAT translation table 28.36.39.20 Source IP
