  55 Middleware, Application protocol gateways:
  56 \begin{itemize}
  57         \item Constrained Application Protocol \cite{draft-ietf-core-coap-18}
  58         \begin{itemize}
  59                 \item machine-to-machine
  60                 \item everything-built-in
  61                 \item discovery over multicast, service discovery over /.well-known
  62                         entry-point
  63                 \item maps to HTTP => stateless
  64                 \item low protocol overhead and parsing complexity (binary messages)
  65                 \item only draft status
  66                 \item UDP with Ack and IDs instead of TCP... (limited state machine)
  67                 \item proxies
  68                 \item asynchronous messages
  69         \end{itemize}
  70         \item MQ Telemetry Transport \cite{mqtt}
  71         \begin{itemize}
  72                 \item TCP/IP
  73                 \item small overhead: 2 byte header + variable header length
  74                 \item publish-subscribe with topic names
  75                 \item binary protocol
  76                 \item discovery?
  77         \end{itemize}
  78         \item Devices Profile for Web Services \cite{zeeb-moritz-ws4d}
  79         \begin{itemize}
  80                 \item TCP/IP -> HTTP -> SOAP -> Web Services. Overhead!
  81                 \item but very extendable and composable
  82                 \item discovery as a service
  83                 \item focused on multiple platforms, deeply embedded and servers
  84                 \item IPv6 partly experimental
  85                 \item ROM usage of uDPWS: 45 kByte
  86         \end{itemize}
