Towards a flexible data center fabric with source routing
Sangeetha Abdu Jyothi, Dong Mo, P. Brighten Godfrey · 2015
An emerging architecture for software-defined data centers andWANs is the network fabric, where complex application-sensitive functions are factored out, leaving the network itself to provide a simple, robust high-performance data delivery abstraction. This requires performing route optimization, in real time and across a diverse choice of paths. A large variety of techniques have been proposed to provide path diversity for network fabrics. But, running up against the constraint of forwarding table size, these proposals are topology-dependent, complex, and still only provide limited path choice which (we show) can impact performance.
