53 \todo
54 \pages{3}
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}
87
88 \end{itemize}
