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