Internet connectivity at the AS level, defined in terms of pairwise  
logical peering relationships, is constantly evolving.
This evolution is largely a response to economic, political, and  
technological changes that impact the
way ASs conduct their business. We present a new framework for  
modeling this evolutionary process
by identifying a set of criteria that ASs consider either in  
establishing a new peering relationship
or in reassessing an existing relationship. The proposed framework is  
intended to capture key elements
in the decision processes underlying these relationships. We propose  
models to capture the decision processes of customer
ASs that are distinctly different from models for peer ASs. To  
reflect the enormous heterogeneity among customer or peer ASs, our
models are also flexible enough to accommodate a wide range of AS- 
specific objectives. We demonstrate the potential
of this new framework by considering different decision models in  
various realistic "what if" experiment scenarios.
We implement these decision models to generate and study the  
evolution of the resulting AS graphs over time,
and compare them against observed historical evolutionary features of  
the Internet at the AS level.
