Hi,

I have carefully read the problem statement draft. It’s clear and concise to
describe the motivation and goal of DECADE. However, I have some confusion
about its details as follows:

1 In section 3.1-P2P infrastructural stress and inefficiency, the third
paragraph about the comparion with LEDBAT, there is a sentence “Also, when
adopted, these techniques do not remove all inefficiencies, such as those
associated with traffic being sent upstream as many times as there are
remote peers interested in getting the corresponding information.” I don’t
catch the main idea of this sentence. What is “those associated with traffic
being sent upstream as many times as there are remote peers”? What is
“corresponding information?”Do you mean LEDBAT only considers peers in local
network? I think this sentence is quite hard to understand.

2 The section 3 describes the problems that would be targeted by DECADE. One
side is to reduce the stress on infrastructure, which benefits ISP. The
other side is to increase flexibility on content sharing, which benefits
users. However, I don’t think the titile of section 3.3 “ineffective
integration of P2P applications” is very appropriate. In my opinion, this
section describes the requirements for P2P applications to utilize
infrastructural resources, which doesn’t match the “ineffective
integration”. I suggest a more appropriate title to highlight the need of
infrastructural resources for P2P applications.

Besides, I think DECADE is a very promising service to transfer the storage
and management of content into the cloud, which envisions the future P2P
applications. Can we add the hot concept of “cloud” into the draft? My 2
cents.
