Buffered Crossbar Fabrics Based on Networks on Chip
— Buffered crossbar (CICQ) switches have shown a high potential in scaling Internet routers capacity. However, they require expensive on-chip buffers whose cost grows quadratical...

Lower bounds for dynamic connectivity
We prove an (lg n) cell-probe lower bound on maintaining connectivity in dynamic graphs, as well as a more general trade-off between updates and queries. Our bound holds even if t...

Distance Oracles for Sparse Graphs
Abstract— Thorup and Zwick, in their seminal work, introduced the approximate distance oracle, which is a data structure that answers distance queries in a graph. For any integer...

Providing flow based performance guarantees for buffered crossbar switches
Buffered crossbar switches are a special type of combined input-output queued switches with each crosspoint of the crossbar having small on-chip buffers. The introduction of cross...
