Abstract
We present a monitoring system for a dynamic network in which a set of domain nodes shares
the responsibility for producing and storing monitoring information about a set of visitors. This
information is stored persistently when the set of domain nodes grows and shrinks. Such a
system can be used to store traffic or other logs for auditing, or can be used as a subroutine
for many applications to allow significant increases in functionality and reliability. The features
of our system include authenticating visitors, monitoring their traffic through the domain, and
storing this information in a persistent, efficient, and searchable manner. The storage process
is O(log n)-competitive in the number of network messages with respect to an optimal offline
algorithm; we show that this is as good as any online algorithm can achieve, and significantly
better than many commonly used strategies for distributed load balancing.
