We consider the following question: what consistency model is appropriate for coordinating
the actions of a replicated set of SDN controllers? We first argue that the conventional …

We present xFabric, a novel datacenter transport design that provides flexible and fast
bandwidth allocation control. xFabric is flexible: it enables operators to specify how …

Programmable data planes, PDPs, enable an unprecedented level of flexibility and have
emerged as a promising alternative to existing data planes. Despite the rapid development …

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 …

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 …

Due to flow dynamics, a software defined network (SDN) may need to frequently update its
data plane so as to optimize various performance objectives, such as load balancing. Most …

Network updates, such as policy and routing changes, occur frequently in software-defined
networks (SDNs). Updates should be performed consistently, preventing temporary …

With the rise of software defined networks (SDNs), there is a growing interest in dynamic and
centralized traffic engineering, where decisions about forwarding paths are taken …

Software-defined networking (SDN) has emerged as a new network architecture, which
decouples both the control and management planes from data plane at forwarding devices …

Software-Defined Networks (SDNs) introduce great flexibilities in how packet routes can be
defined and changed over time, and enable a more fine-grained and adaptive traffic …
