Network
X-ities: -- Foundations and Applications
Description
Given society's increasing reliance on communication networks such as
the Internet, it is becoming increasingly important that these
networks not only provide good performance, but do so in the face of a
complex, uncertain, error-prone, and ever-changing environment. The
need for such "robust" network operation leads to a set of design
considerations that we refer to as the network X-ities (since
they all end in "ity"): non-fragility, manageability, diagnosability,
optimizability, scalability, and evolvability. Although these X-ities
are crucially important in designing and analyzing robust networks and
protocols, they often lack theoretical foundations, quantitative
frameworks, or even well-defined metrics and meaning. The goal of
this project is to begin to build a solid, quantitative foundation for
explicitly considering the X-ities in the design and analysis of
network architectures and protocols. We do so by considering a number
of specific problems, broadly in the area of routing protocols, that
allow us to concretely address several of the X-ities and to begin to
draw larger lessons from commonalities among the problems studied.
