Gurbani Review Date: Oct-15-2015 IETF LC End Date: Not known IESG Telechat date: Oct-15-2015 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.
