Re: [ppsp] WG Last Call for draft-ietf-ppsp-problem-statement

["Y. Richard Yang" <[e-mail]>]

Hi Yunfei and Rui,

The idea of showing a use case of a proxy is good and helpful. One short 
comment is that I am not sure if it needs two sub sections 5.4/5.5. 
Maybe a single P2P proxy subsec is enough? Inside the subsec, it can 
mention multiple instances. Just a short suggestion that you may consider.

Thanks!

Richard
