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 …

Network is dynamic and requires update in the operation. However, many confusions and
problems can be caused by careless schedule in the update process. Although the problem …

We study consistent migration of flows, with special focus on software defined networks.
Given a current and a desired network flow configuration, we give the first polynomial-time …

We consider the problem of finding efficient methods to update forwarding rules in Software
Defined Networks (SDNs). While the original and updated set of rules might both be …

We propose FLIP, a new algorithm for SDN network updates that preserve forwarding
policies. FLIP builds upon the dualism between replacements and additions of switch flow …

The emerging momentum of digital transformation of industry, ie Industry 4.0, poses strong
demands for integrating industrial control networks, and Ethernet to enable the real-time …

With the rise of Software Defined Networks (SDN), there is growing interest in dynamic and
centralized traffic engineering, where decisions about forwarding paths are taken …

We present ez-Segway, a decentralized mechanism to consistently and quickly update the
network state while preventing forwarding anomalies (loops and black-holes) and avoiding …

With the popular applications of SDN in load balancing and failure recovery, the controller
schedules affected flows to redundant paths to avoid network congestions and failures by …

Network updates such as policy and routing changes occur frequently in Software Defined
Networks (SDN). Updates should be performed consistently, preventing temporary …
