Perspectives on Router Buffer Sizing: Recent Results and Open Problems
Feb 2009
The past few years have witnessed a lot of debate on how large Internet router buffers should be. The widely believed rule-of-thumb used by router manufacturers today mandates a buffer size equal...

Shared Versus Dedicated Buffers for Real-Time Traffic in Optical Routers With Very Small Buffers
Oct 2008
When TCP and real-time (UDP) traffic multiplex at an optical packet router with very small buffers (less than 50 KiloBytes), the authors recently showed that UDP packet losses can increase with...
