Relating Two Formal Models of Path-Vector Routing
Abstract
This paper unifies two independently developed formalisms for path-vector routing protocols such as the Border Gateway Protocol (BGP), the standard interdomain routing protocol for the Internet. The works of Griffin, Jaggard, and Ramachandran [4] and Sobrinho [8] proved conditions for guaranteed protocol convergence, but as they operate at different levels of abstraction in modeling the protocols, the relationship between them is not obvious. Here we provide a rigorous translation between the two frameworks and use it to connect the convergence results, yielding a more complete set of analysis tools than in either paper alone. We motivate our discussion by presenting an example of applying both frameworks to analyze a set of protocols; in doing so, we show how the models, in conjunction, give important guidelines for protocol design.
