This document is ready as a Proposed Standard, however, it does have
some minor comments and nits that I detail below.
Major: 0
Minor: 3
Nits: 9
Minor:
- Generally speaking, I think one more round of edits for grammar and
clarity may not be a bad thing.
- S2, "The PPSP Tracker Protocol architecture is intended to be
compatible with the web infrastructure." What is the "web
infrastructure"? How is it defined? What does it mean to be
compatible with it? Perhaps you meant that the PPSP TP is a request-
response protocol, which characterizes many "web protocols"?
- S3.2.5, Table 4: "available_bandwidth | Upstream Bandwidth
available" is this provisioned upload bandwidth or instantaneous
upload bandwidth?
Nits:
- General comment: too much use of gratuitous capitalization (Request
message, Tracker, Peer etc.)
- S1.1, CHUNK is better defined as "An uniformly sized atomic subset of
the resource that constitutes the basic unit of data organized in P2P
..."
- S1.1, For uniformity when defining terms, you may want to think of
starting the definition of live streaming as "LIVE STREAMING: Refers to
..."
- S1.1: The taxonomy of a peer into a leecher or a seeder appears to be
absolute. In real swarms (BitTorrent), a peer trades chunks with
other peers, so it is a leecher but also a provider for certain
chunks. This eventuality is not considered here.
- S1.2.1, what is the implication of the prefix "[Peer Protocol]" in the
numbered steps shown? Is it a reference (using syntax like we use for
references), or is it implying that the protocol used by a peer in
these steps is the peer protocol? If so, why not put the RFC/I-D
number of the peer protocol there?
- S1.2.2, s/Once CONNECTed/Once connected/
- S2.2, what is an "action signal"? Perhaps easier to simply say that
"This Request message is used when ..." Same with "information
signal".
- S2.3.1, s/register on a tracker/register with a tracker/
- S3.1, "turning the definitions for JSON objects extensible." I cannot
quite parse that. Sorry.
Thanks,
- vijay
