- 34. PERFORMANCE ISOLATION IN DATACENTERS β’ Custom congestion control in Fat Tree topologies. β’ Measurements of performances of flows which belongs to differentTenants. Such flows compete for the link bandwidth. β’ Measurements on the status of the queues during congestion events. β’ Reaction of the flows which will have their rate reduced to their paid bandwidth, and can also share any remaining left capacity on the link. β’ How performances change adopting different multipath strategies.
- 35. PRISTINE:VALIDATION EXPERIMENTS β’ Authentication β’ password-based,asymmetric keys β’ Encryption β’ Explicit congestion avoidance β’ Scalable routing β’ Location-independent application names β’ Mapping of application names to node addresses at multiple layers. 35
