Datacenters provide cost-effective and flexible access to scalable compute and storage
resources necessary for today's cloud computing needs. A typical datacenter is made up of …

Computer networks have become a critical infrastructure. In fact, networks should not only
meet strict requirements in terms of correctness, availability, and performance but they …

WAN bandwidth remains a constrained resource that is economically infeasible to
substantially overprovision. Hence, it is important to allocate capacity according to service …

Private WANs are increasingly important to the operation of enterprises, telecoms, and cloud
providers. For example, B4, Google's private software-defined WAN, is larger and growing …

Cloud applications generate a mix of flows with and without deadlines. Scheduling such mix-
flows is a key challenge; our experiments show that trivially combining existing schemes for …

SDN simplifies network management by relying on declarativity (high-level interface) and
expressiveness (network flexibility). We propose a solution to support those features while …

Cloud applications are increasingly distributing data across multiple regions and cloud
providers. Unfortunately, widearea bulk data transfers are often slow, bottlenecking …

This paper presents an efficient topology and route management approach in Software-
Defined Wide Area Networks (SD-WAN). Traditional WANs suffer from low utilization and …

Inter-datacenter wide area networks (inter-DC WAN) carry a significant amount of data
transfers that require to be completed within certain time periods, or deadlines. However …

Bulk transfer on the wide-area network (WAN) is a fundamental service to many globally-
distributed applications. It is challenging to efficiently utilize expensive WAN bandwidth to …
