[Iccrg] New draft for review: draft-mayutan-ledbat-congestionarchitecture-00.txt

[Lisong Xu]

Mayutan, Xiaoming, and K. K.,

Thanks for your work. Below are some quick comments.

1. Section 3 "Design goals". There are actually 8 goals: 1, 2, ..., 8 
instead of 1, 1, ... ,7.

2. It would be better to explain what "network friendly" means.

3. It would be better to explain the difference between "TCP", "Standard 
TCP", and "network friendly TCP". Are they referring to the same TCP or 
different TCP's?

Thanks
Lisong
