+ Students I guess many generations of young engineers and future software developers have learnt TCP/IP by looking at the IP and TCP headers in PCAP files. Apparently, it has worked to some extend in the last 35 years or so… Of course, there are alternatives in teaching transport protocols to those who are not on IETF e-mail list (so far). But do we really know whether it will work well? Anyway, Gorry and others on the list may understand that „use case“ much better than me ;-) So I’ll better shut up. Michael Von: Gorry Fairhurst<mailto:gorry@erg.abdn.ac.uk> Gesendet: Samstag, 12. Oktober 2019 09:49 An: Christian Huitema<mailto:huitema@huitema.net> Cc: tsvwg@ietf.org<mailto:tsvwg@ietf.org> Betreff: Re: [tsvwg] [saag] TSVWG WGLC: draft-ietf-tsvwg-transport-encrypt-08, -> logging I'm intrigued by how far we can understand opportunities for open client logs to replace pcap dumps, and would like to delve a little deeper into what we understand - there seem many possible actors and that may be interesting to look at a few viewpoints: * a user of a transport protocol (e.g., understanding cost/benefit of feature choices); * a protocol developer (e.g., debugging transport interactions end to end); * a service provider (e.g., trying to understand performance impairments in the network); * researchers/equipment developers seeking to correlate/tune transport timing with network policies (e.g., interactions between congestion control and link scheduling); * exploring traffic archives (e.g., trends in what is supported or determine when an anomoly appeared). I've taken all of these viewpoints at some time using pcap to look at TCP. Clearly when we use QUIC, there can be alternatives and there is now some experience with client (and server) logs, what do you think we can usefully say in addition to or instead of what the draft says about logging (currently mentioned only briefly in section 6.1) ? The text on spin-bit could indeed be developed a little (the present text predates the spin bit being incorporated as an optional part of the base spec). What do you think should be said (currently at the end of 6.4)?
