Proposed Solution

Simulate the CCNx code before deployment:

Camara,Urbani (INRIA) Experimentation/CCN Sept 2012 6 / 11

slide-19
SLIDE 19

Proposed Solution

Simulate the CCNx code before deployment:

◮ Reuse existing layer 1/2/3/4 models from ns-3

How do I use it ?

Roughly:

◮ Download/install ns-3 ◮ Download/install ns-3 DCE module ◮ Recompile CCNx with magic option ◮ Write simulation script ◮ Run ◮ Analyse traces

What we would like to learn

If you tried DCE/CCNx:

◮ What sucks about it ? ◮ How can we improve it ? ◮ How can we write more test scripts for CCNx ?

If you tried DCE/CCNx:

◮ What sucks about it ? ◮ How can we improve it ? ◮ How can we write more test scripts for CCNx ?

If you did not try it:

◮ Why ? ◮ What is missing to make you try it ?

Scalability

Memory:

◮ Fixed, 1MB/node ccnx ◮ Fixed, 0.02MB/node ns-3 TCP/IP ◮ Fixed, 0.5MB/node linux TCP/IP ◮ Linear in number of bytes of packets in flight

CPU:

◮ Real time limit: 20 nodes, 200K file transfer
