[codes-ross-users] codes simple net problems

[Mubarak, Misbah]

Hi Lei,

Here is some feedback regarding your questions:

- Yes, for transferring large data through simple-net you will need to use
the message_size parameter.

In terms of simulation performance, I had a question for John i.e. do we
break down messages into packets at the model-net layer for simple-net
model as well? If so, the simulation may be getting slower due to a use of
very small packet size (by default it is 512 bytes in the configuration
file). 
 
- The bandwidth is in Megabytes per seconds. Since we are using all lower
cases, it gets confused by Mbps. To make this clear, I have added the
bandwidth units in the example config file.

Thanks,
Misbah
