problem statement
Problem Statement
  • That’s the problem…
    • we’re at a “do what I mean” stage
    • “It’s urgent, make light move faster”
  • Past work
    • Definitions
    • SIP RPH
    • MLPP-that-works
    • Etc
still needed
Still needed:
  • That’s what we’re here to figure out
  • Applications need a way to specify
    • Underlying traffic class
    • Authentication to use it
    • Application behaviors that give desired service to users
    • Network/Network Interface configurations that can be predictably negotiated among providers
authentication problems in voice video
Authentication problems in voice/video
  • Who gets to use a service?
  • Voice/video: usage of RPH needs authentication
  • Integration with existing network layer work and RPH
smtp electronic mail
SMTP Electronic Mail
  • Need to be able to specify that an email must be delivered within a stated interval
  • Service to an authenticated user:
    • “Resource Priority Header” in envelope
    • Policy authentication (DKIM?)
    • Server rules on queuing, retransmission
sip instant messaging
SIP Instant Messaging
  • Wants some kind of precedence service
    • RPH for instant messaging
    • What does assertion of precedence mean?
  • Services:
    • SIMPLE (SIP)
    • XMPP (Jabber)
    • Commercial services like AIM/Yahoo?
file transfer and http
File Transfer and HTTP
  • Need to be able to assert a network layer traffic class that a file transfer will use
  • Authentication of use of certain traffic classes
