The Design Space of Network Mobility
Pamela Zave, Jennifer Rexford · 2013
The Internet is increasingly mobile. Because mobility is difficult to implement at Internet scale, there is a large and confusing landscape of mobility proposals which cannot easily be compared. This tutorial is based on the geomorphic view of networking, which is a uniform framework for describing many key aspects of network architecture. The geomorphic view shows that there are two distinct patterns for implementing mobility, each with its own range of design choices and costs versus benefits. We use these patterns to classify and explain a representative sample of mobility mechanisms, abstractly yet precisely. The patterns also serve as a basis for evaluating properties of these mechanisms such as resource costs and scalability, and for considering composition of mobility mechanisms. 1
