Suppose we have a hierarchical DCN design as shown in the figure below. Each rack has 20 hosts and we need high throughput connections on flows from hosts i=1.... 20 in each of racks 1, 2, 3, 4 to hosts j-1,.,20 in each of racks 5, 6, 7, and 8 respectively. Each host is connected to the TOR with a 1Gbps link, and the connections from TORS to Tier-2 and Tier-2 to Tier-1 switches are 10Gbps. Using this architecture: What is the end-to-end throughput for a host i in rack 2 to the corresponding host j in rack 6 in the architecture below? a) 500 Mbps b) 125 Mbps c) 2 Gbps d) 1 Gbps Border router Access Router Tier-1 switches Suppose we have a hierarchical DCN design as shown in the figure below.

Answer rating: 100% (QA)

To calculate the endtoend throughput for a host in rack 2 to the corresponding host in rack 6 we need to consider the slowest part of the path because ... View the full answer
