Abstract Software-Defined Networking (SDN) architecture has emerged in response to
limitations of traditional networking architectures in satisfying today's complex networking …

Software-defined network (SDN) has become one of the most important architectures for the
management of largescale complex networks, which may require repolicing or …

When network is undergoing problems such as congestion, scan attack, DDoS attack, etc.,
measurements are much more important than usual. In this case, traffic characteristics …

Large cloud service providers have invested in increasingly larger datacenters to house the
computing infrastructure required to support their services. Accordingly, researchers and …

Traffic optimizations (TO, eg flow scheduling, load balancing) in datacenters are difficult
online decision-making problems. Previously, they are done with heuristics relying on …

Modern datacenter applications demand high throughput (40Gbps) and ultra-low latency (<
10 μs per hop) from the network, with low CPU overhead. Standard TCP/IP stacks cannot …

Traditional end-host network stacks are struggling to keep up with rapidly increasing
datacenter access link bandwidths due to their unsustainable CPU overheads. Motivated by …

We present the design, implementation, and evaluation of CONGA, a network-based
distributed congestion-aware load balancing mechanism for datacenters. CONGA exploits …

One of the major applications of future generation parallel and distributed systems is in big-
data analytics. Data repositories for such applications currently exceed exabytes and are …

Can we get network latency between any two servers at any time in large-scale data center
networks? The collected latency data can then be used to address a series of challenges …
