Oblivious Routing in On-Chip Bandwidth-Adaptive Networks

Free registration required

Executive Summary

Oblivious routing can be implemented on simple router hardware, but network performance suffers when routes become congested. Adaptive routing attempts to avoid hot spots by re-routing flows, but requires more complex hardware to determine and configure new routing paths. The authors propose on-chip bandwidth-adaptive networks to mitigate the performance problems of oblivious routing and the complexity issues of adaptive routing.
