[e2e] Application Traffic Characteristics measurement.

[Xie]

Hi Dear Sudeep,

There are several commercial network test instruments such as Avalanche of Spirent, IPIE of Navtel, and other instrument of Agilent for synthetic traffic generating at application level.  NetTurbo is built on ourselves hardware platform with network processor.  If you want, we will send these metrics data to you on this April when we will perform measurement experiment on a carrier's network with NetTurbo.

Cheers,
Xie
