Answer:
Explanation:
Given that:
The no of flow pairs = 80
Each link's capacity = 10 Gbps
Link capacity amongst TOR switches and hosts = 1 Gbps
Because each connection is distributed among all flows, each flow crossing the same link distributes the link's capacity with the other flows. The connection capacity needed by each flow in the network is determined by the highest flow rate.
Maximum rate flow = [tex]\dfrac{link's \ capacity}{no \ of \ flow \ pairs}[/tex]
[tex]= \dfrac{10 \ Gbps}{80}[/tex]
Since 1 Gbps = 1000 Mbps
[tex]= \dfrac{10000}{80}[/tex]
= 125 Mbps
Hence, maximum rate flow = 125 Mbps
b.
Each switch at Tier-1 is connected to each and every switch at Tier-2 in the highly integrated structural topology. As a result, there are n-disjoint routes between tier-2 and tier-1 switches.
Number of paths between tier-1 and tier-2 is 4, thus, there exist four paths from tier-1 switch to tier 2.
The capacity whereby all data routes convey is determined by the maximum rate of flow.
number of available paths = 4
Each link's capacity = 10 Gbps
Maximum flow rate = 4 × 10 Gbps
Maximum flow rate = 40 Gbps
c.
Because each connection is distributed between all flows, each flow crossing a similar link distributes the link's capacity with other flows.
number of flow pairs = 160
Each link's capacity = 10 Gbps
maximum rate of flow = 10000 Mbps / 160
= 62.5 Mbps
For 160 flow pairs, maximum flow rate = 62.5 Mbps
Each switch in Tier-1 communicates with each switch in Tier-2 in the highly linked topology network. As a result, n-disjoint routes between tier-2 and tier-1 switches are possible. As there exist 20 hosts engaged in the network around each host, the number of routes from either a tier-1 switch or tier-2 switches is 20.
here;
no of paths = 20
each link's capacity = 10 Gbps
Maximum flow rate = 20 × 10
= 200 Gbps
As such, with 160 pairs of flow, maximum flow rate = 200 Gbps
