Cloudlet starting execution time when running NetworkTopology links

[stec]

Hello All,

I have created a simple example for simulating a network of 2 users
that run 1 cloudlet in 1 VM of 1 dc etc. When I run the simulation
without network connections I get as output Start Time: 0 (obviously)
for both users.

The issue is when I create the following network:

NetworkTopology.addLink(nodeDC1,nodeBR1,1,1);
NetworkTopology.addLink(nodeDC2,nodeBR2,1,1);
NetworkTopology.addLink(nodeBR1,nodeBR2,1,1);

The output is

USER 1:
Cloudlet ID STATUS Data center ID VM ID Time Start
Time Finish Time
0 SUCCESS 2 0 160 4
164
USER 2:
Cloudlet ID STATUS Data center ID VM ID Time Start
Time Finish Time
0 SUCCESS 3 0 160 10
170

How this number is caclulated?? (The start time 4)
and why for the second user this time is 10?

Thanks!
