Title: Minlan Yu (Princeton): TBA
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.
However, 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.
