Why SSH2 isn't there? It's a routable protocol with persistent connection, and is one of the best for its security track record.

I would say that the problem you are trying to describe in the article is more applicable to data structures and formats that are pushing over the wire, rather than ways of delivering them.

I liked your article.  I do think that for the deeply embedded sensor space additional protocols are required.   For example, CoAP is the protocol which ARM is pushing in this space while ZeroMQ is one of the protocols used to collect  sensor data at CERN.  Memory footprint is very important for smaller systems and these additional protocols do a better job of this.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
