A network consists of 7 nodes n0-n6 connected in ring topology. Each link is a duplex connection of 1Mbps bandwidth and 10ms latency. Data packets need to be transferred from node n0 to node n3 taking the shortest path. This is a dynamic network where the routing adjusts to link failures as node n2 goes in sleep mode.
Fig 1: Starting from 0.5s node n0 sends data traffic to n3 taking the shortest path
Fig 2: At 1.0 packets are dropped as node n2 goes in sleep mode resulting in link failure between n1-n2 and n2-n3
Fig 3: Dynamic routing ensures data traffic flows through a different route
Fig 4: After 2.0s, node n2 is re-established and takes the shortest route
