Extend the flow properties and definitions to the multiple-source, multiple- sink problem. Show that any flow in a multiple-sour

ce, multiple-sink flow network corresponds to a flow of identical value in the single-source, single- sink network obtained by adding a supersource and a supersink, and vice versa.

Answer:

We add a super source s and add a directed edge (s, si) with capacity c(s, si) = ∞ for each i = 1, 2, . . . , m. We also create a new super sink t and add a directed edge (ti, t) with capacity c(ti, t) = ∞ for each i = 1, 2, . . . , n. The single source s simply provides as much flow as desired for the multiple sources si, and the single sink t likewise consumes as much flow as desired for the multiple sinks ti.

Because the virtual edges of s and t can consume as much flows as they want, they don't influence the actual edges.

For the Address Block 195.200.0.0/16 a. If you have 320 Customers that need 128 addresses/customer - will there be enough addres
Shkiper50 [21]

Answer / Explanation:

195.200.0.0/16

Note: Class C address can not be assigned a subnet mask of /16 because class c address has 24 bits assigned for network part.

2ⁿ = number of subnets

where n is additional bits borrowed from the host portion.

2ˣ - 2 = number of hosts

where x represent bits for the host portion.

Assuming we have 195.200.0.0/25

In the last octet, we have one bit for the network

number of subnets  = 2¹  =2 network addresses  

number of host = 2⁷ - 2= 126 network addresses per subnets
