Title: Scalable Enterprise Networks with Inexpensive Switches
Enterprise networks are growing larger and ever more difficult to manage.
Several emerging techniques help improve network management:
flat addressing to support host mobility, shortest-path routing to improve
performance, and flow-based switches to enable fine-grain policies.   
these techniques introduce scalability challenges in enterprises with many
hosts, switches, and flow rules, forcing the use of expensive switches with
large, power-hungry memory for processing data packets.  In our work, we
improve the scalability of enterprise networks through a combination of new
data structures that make effective use of limited memory and traffic
indirection that minimizes state required at each switch.  We first present
BUFFALO, which uses Bloom filters to reduce memory usage in switch
forwarding tables.  Then, we present DIFANE, a distributed architecture for
managing the flow rules that enforce fine-grain policies for access control,
routing, and traffic measurement.  Both BUFFALO and DIFANE can be easily
implemented with small modifications in today's switches, as demonstrated by
our prototypes built using the Click modular router.

Minlan Yu is a 4th year Ph.D. student working with Jennifer Rexford in the
computer science department at Princeton University. She received her B.A.
in computer science and mathematics from Peking University in 2006 and her
M.A. in computer science from Princeton University in 2008. Her research
interest is in network virtualization, enterprise and data center networks.
