Thanks for a readable and informative document. I have just a few
very petty comments.
The Abstract says...
This document surveys deployed and experimental in-network storage
systems and describes their applicability for DECADE.
This may be too terse. Replacing "DECADE" with the name of the working
group doesn't really help. Can you spell out what you mean by "DECADE"
High-capacity and low-cost in-network storage devices introduces
Deploying a CDN for publicly
available content is expensive.
Is the price really a function of whether the content is publicly
Second, applications may benefit from explicit control of in-network
storage, which P2P caches do not provided.
CDMI-specific operations are specified in
Object Notation (JSON) object, but the protocol also defines
interfaces in which the contents of data objects can be written via
simple HTTP GET/PUT operations.
I can't parse the start of the sentence.
A Content Delivery Network (CDN) provides services that improve
network performance by maximizing bandwidth, improving accessibility
and maintaining correctness through content replication.
Technically they don't change the bandwidth. I'm not sure they maximize
the utilized bandwidth either. But I'm being pedantic.
A key aspect of NDN is that router have the capability to cache the
In addition, making use of P2P caches

P2P caches operate similarly to web caches, in that they temporarily

The draft references the DECADE problem statement draft for further discussions
on use cases. Additionally, it might be useful to provide a brief description
(e.g., a one liner) of the prototypical use case for DECADE. For example the
problem statement draft provides this example:
"As a simple example, a peer of a P2P application may upload to other peers
through its in-network storage, saving its usage of last-mile uplink bandwidth."
In the section on Amazon S3, an additional example of a third-party service
(which is very popular nowadays) that uses it would be dropbox.

Minor editorial suggestions.
In section 4.5.2:
provider can access network edge servers and store content on them.
Or edge servers can retrieve content from content providers.
Combine these two sentences into one with a comma.
In section 4.7:
A key aspect of NDN is that router have the capability
