The list of work during the past one week is shown below:

1. revise the journal submission for leakage reduction

2. study the statistics behavior of VoIP packet streams
for our dynamic power management in network processor. 
[1] studies the modeling of VoIP traffic. At call level,
it shows that the popular Poisson distribution are good 
enough for VoIP call arrival modeling, while the call
holding times should be model by the generalized Pareto
distribution. Due to different codecs for VoIP, the packet
level distributions present different characteristics. 
Usually the voice traffic streams produced by codecs
use silence compression and generate active (On) and 
inactive (Off) periods alternatiely. The generalized
pareto distribution can be used as an accurate model for
the On and Off periods too. Our focus should be the
packet level stream traffic. Further readings are necessary
to fully understand the assumption and conclusion.

3. start working on the implementation of share cache
in the CMP simulator.

4. modify the CMP simulator for DVS
