SMF: A New Era for Data Centers?

SMF: A New Era for Data Centers?

To support this growth, data center network architectures have evolved into scale-out designs, providing the plumbing to carry large amounts of latency-sensitive application traffic between racks. To improve bandwidth utilization, data centers are also moving from 10GbE to 40GbE to 100GbE, providing bigger pipes for transmitting application traffic at line rates. At the same time, more and more servers are being packed into data centers

Adaptive Flowlet Splicing – VCF's Fine-Grained Adaptive Load Balancing Without Packet Re-ordering

Adaptive Flowlet Splicing – VCF's Fine-Grained Adaptive Load Balancing Without Packet Re-ordering

Multi-path forwarding has been deployed extensively in data center networks as a way to increase capacity and resiliency. Flow-based hashing is widely used to split traffic onto multiple paths. However, such method may work poorly  when there is a small number of  disproportionaly large flows exists. This post will explore a dynamic load balancing mechanism called daptive flowlet splicing (AFS).
