OOB Update

Andrew Deason

Sine Nomine AssociatesEuropean AFS & Kerberos Conference 2014


Overview

Overview

  • Review

  • Filter/pipeline framework

  • Current/future status


Review

Review

  • EAKC 2012 (Edinburgh)

  • Initial project: TCP, throughput

  • New effort: more general


Oob pipeline

OOB Pipeline

  • Originally, single “mech”s

  • TCP-gzip, Rx-gzip, UDT-gzip, …

  • Need a new approach


Quick notes

Quick notes

  • Terminology: “mech” “iface”

  • You may want to write a mech some day!


Oob pipeline1

OOB Pipeline

  • Client requests: compress_mech | encrypt_mech | tcp_mech

tcp_mech

compress_mech

encrypt_mech


Oob pipeline interfaces

OOB Pipeline (interfaces)

tcp_mech

wstream_iface

wstream_iface

compress_mech

encrypt_mech


Oob pipeline interfaces1

OOB Pipeline (interfaces)

rsync_mech

tcp_mech

rwstream_iface


Oob pipeline terminals

OOB Pipeline (terminals)

  • Let’s simplify a bit:

  • Not really correct…

tcp_mech


Oob pipeline terminals1

OOB Pipeline (terminals)

fetch_iface

tcp_mech


Oob pipeline terminals2

OOB Pipeline (terminals)

  • But TCP doesn’t know about files…

fetch_iface

terminal_iface

tcp_mech


Oob pipeline terminals3

OOB Pipeline (terminals)

  • What actually gets sent?

filedata_mech

tcp_mech

fetch_iface

terminal_iface

wstream_iface


Oob pipeline2

OOB Pipeline

  • What actually gets sent?

filedata_mech

tcp_mech

fetch_iface

terminal_iface

wstream_iface


Oob pipeline3

OOB Pipeline

  • Interfaces automatically negotiated

  • Object-oriented C?

  • Other languages?


Present future

Present/Future

  • Still not “done” yet

  • Volserver, other services

  • DSOs, scripts
