Abstract
Seeking to understand the potential of network
coding in future internet endeavors, we consider the vital
role of network topology with respect to the potential benefits
of Random Linear Network Coding (RLNC). First, we
propose a set of metrics that capture the essential trade-offs
between throughput, confidentiality and decoding delay. Using
large network simulation, we are able to evaluate the
behavior of RLNC for various topological classes based on
random graphs. Our results show significant differences between
local dissemination of information (typical of wireless
networks) and long range connectivity (typical of peerto-
peer environments). We believe that our results can help
pave the way for the creation of better overlay topologies for
RLNC protocols in future internet applications.
