CDS as architecture• Architecture= “constraints that deconstrain”
– Constraint = CDS core concepts and math– Deconstraint = connections between new applications
and (also possibly new) math
• How to explain this?• Laws: Universal constraints on achievable
robust performance and efficiency• Architectures: Universal organizational
strategies to flexibly achieve what is possible• Case studies: concrete and familiar examples to
illustrate “universals”8

Core protocols
• From Architecture slides, understanding the “OS” is difficult and essential
• But term “OS” seems to confuse• Replace with “core protocols”?• Highly conserved/constrained core (knot)• Highly diverse/deconstrained edges
• What is “CDS” in this context?9

Caveats
• Many ideas are classic “robust control”, but much of the organization (the architecture) is fairly new
• Motivating case studies also new
• Many rough edges• Nobody is working on it quite like this• We want to change that
