# pag 8 in point 1.2

I don't understand the example in the notes that sais:

For example: with I=2, n0=n1=1...

well, my question is that I don't understand the meaning of: x0=0.1c, x1=0.5c, x2=0.1c, and x0=0.1c,x1=0.9c,x2=0.1c

what's the meaning of that? How to use it?Why is the reason of these numbers?

all right. I've understood.

I is the number of links; the links are conncatanated (serial);
0-flow is only one and uses all links;
number of i-flows is ni, and all ni i-flows use only the i-th link.

>For example: with I=2, n0=n1=1...

and n2=1.

then by water filling algorithme (read theory please): x0=x1=x2=0.5c, i.e., everyone gets half of the link(s) capacity, 0-flow on both links, 1-flow on first link, 2-flow on second link.

>well, my question is that I don't understand the meaning of: x0=0.1c, >x1=0.5c, x2=0.1c,

x0=0.1c means 0-flow gets 0.1 of link capacity... that is the "meaning"
(the above numbers would be a max-min fair alocation for n0=n2=5, n1=1)

>and x0=0.1c,x1=0.9c,x2=0.1c

>what's the meaning of that? How to use it?Why is the reason of these >numbers?

see the above comments and study water-filing alogrithm
