	abstract = {We introduce an architecture for {\textquoteleft}{\textquoteleft}Intradomain Overlays{\textquoteright}{\textquoteright}, where a  subset of routers within a domain is augmented with a dedicated
  host.  These strategically placed hosts form an overlay network, and
  we describe a number of applications for such
  overlays.  These applications include efficient network  
  monitoring, policy- and load-based packet re-routing, and network
  resource accounting.
         
  In this paper, we elaborate on the network monitoring application
  and describe a distributed protocol for monitoring routers within an
  AS which has been augmented with a few overlay nodes.  The routers
  and other infrastructure are unaware of the overlay nodes, and the
monitoring of individual elements is conducted using plain SNMP.  We
  describe techniques for efficiently synthesizing and transporting
  the monitored SNMP data, and present results using trace data
  collected from an AS with 400+ routers.  Our results show that the
  overlay-based monitoring reduces overheads by 2--4 orders of
  magnitude, and thus enables much finer grained monitoring and
  traffic engineering than is otherwise possible.
