Hi, I think this document should explicitly explains that quantum networks may and may not execute forwarding (data) in Subsec. 5.1. Routing and forwarding are different functionalities. Routing decides which way to go, forwarding executes the transfer obeying the decision. The 1st and the 2nd generation (Muralidharan's definition) quantum networks execute routing and swapping, instead of forwarding. The 3rd generation does routing and forwarding. "Routing and swapping" might have to be "routing and measuring". "Routing and measuring" can intuitively cover broader ideas, such as graph state-based routing and surface code quantum communication, that don't execute forwarding and don't execute even entanglement swapping, but execute measurements. (Of course, entanglement swapping has measurements) Muralidharan's three generations should not be explicitly mentioned in the document since more types (generations) of quantum networks would appear in the future. However, I would believe that any types of quantum networking belong to the roughly divided two types of quantum networks, "routing and measuring" and "routing and forwarding". Hence those two types would be worth writing. At least, it is worth writing that forwarding may not exist, as the unique distinction of quantum networking. Such a new section will help network-backgrounded people who may unconsciously suppose store and forward system. The current document implies that there are generations of quantum networks (Subsec. 4.2 Direct transmission mentions "generation"), but no section summarizes generations. The new explanation would solve the wonder of readers raised by the implication. How do you think? I'm going to make a pull request. Please see that. ------------------------------------------------ 永山翔太 Shota Nagayama shota.nagayama@mercari.com https://shota.io/ https://qitf.org/ https://r4d.mercari.com On Mon, Feb 17, 2020 at 7:17 PM Wojciech Kozlowski <W.Kozlowski@tudelft.nl> wrote: > Dear QIRG, > > I have just added a contribution to the elementary link generation section. > Thank you Sara and Marcello. > > Latest version: > > https://github.com/Wojtek242/draft-irtf-qirg-principles/blob/master/draft-irtf-qirg-principles-03.txt > > Diff: > > https://github.com/Wojtek242/draft-irtf-qirg-principles/commit/3952b2f15f3720325ce42c61c8857a2ede1a0f2e > > Moving forward: my plan is now to finalise the principles/goals sections. > Some > feedback has already been given on this subject and I will try to make > sure I > take it all into account. > > I propose that for this part, I first write the update myself based on > feedback > received so far.
