Hi all,
Do we really need the term "Link"? IMO, "Link" in 6TiSCH is same as Bundle. Right?
ThanksQin

Thomas, thanks for jumping into it.    Sure, the typos will be fixed in the next  version  ;)    About the definition of “link” I have to say this is  a  kind of endless story… We have been discussed a lot in the past how to define it, how to make  clear that the concept for 6TiSCH is different from classical  IETF  link  definition,  but it seems we created  confusion, by putting  too  much information all together into  it.    Thomas’s suggestion could  simplify the problem. The  link in fact  exists when the two neighbors have at least  one  cell to exchange pkts.    Thank you. Maria Rita       From: 6tisch [mailto:[e-mail]]On Behalf Of Thomas Watteyne

Subject: Re: [6tisch] comments on latest terminology draft    Randy,    I'll let Maria Rita comment about the typos, I assume it's just a matter to spinning the doc.    About "link", I went back to read the draft. The following definition...    ------------------ A communication facility or medium over which nodes can communicate at the link layer, i.e., the layer immediately below IP.  Thus, the IETF parlance for the term "Link" is adopted, as opposed to the IEEE802.15.4e terminology.  In the context of the 6TiSCH architecture, which applies to Low Power Lossy Networks (LLNs), an IPv6 subnet is usually not congruent to a single link and techniques such as IPv6 Neighbor Discovery Proxying are used to achieve reachability within the multilink subnet. A link is distinct from a track.  In fact, link local addresses are not expected to be used over a track for end to end communication.  Finally, from the Layer 3 perspective (where the inner complexities of TSCH operations are hidden to enable classical IP routing and forwarding), a single radio interface may be seen as a number of Links with different capabilities for unicast or multicast services. ---------------    ... is confusing, to say the least. IMO, it touches on almost all of the IETF work (talking about ND proxy, mutiling subnets, tracks in the definition of link ?!?) , is incredibly confusing, and as a result carries 0 information. What about    A link exists between two nodes when at least one cell is schedule between them.    Thomas             On Mon, Apr 18, 2016 at 8:38 PM, Turner, Randy <[e-mail]> wrote: 
Hi Guys,   I had a couple of comments on the recent -07 terminology draft:   Deterministic Network - "A deterministic network can allocates..." should be "A deterministic network can allocate..."   "6top Data Convey Model" - Model describing how the 6top adaptation layer...<snip> Is this really an adaptation layer? - In the IETF, the term "adaptation layer" has come to mean something different   6p Transaction - "Part of the 6top Protocol, in consists in" should probably be "...consists of"   "Bundle" - typo "usining" should be "using"   "Link" – When I read this description, it sounds similar to an interference domain - should the difference (if any) be spelled out or distinguished ? Or am I the only one that sees this similarity?   Thanks!
