Network Configuration in OpenFlow Networks
نویسندگان
چکیده
Software-defined networking (SDN), and in particular networks based on an OpenFlow control plane, are expected to take significant share in upcoming deployments. Network programmability has emerged as a particularly desirable property for such new deployments, in which logically centralized software will be able to both control and manage operation. This paper focuses on one aspect of network management, namely configuration, in light of the ongoing work in the FP7 ALIEN project to augment a variety of devices with an OpenFlow control plane. In particular, we review management for programmable networks and present how software-defined control can be complemented with software-defined configuration.

Software Defined Networking (SDN) is a new paradigm for communication networks which separates the control plane from the data plane of forwarding elements. This way, SDN constitutes a flexible architecture that allows quick and easy configuration of network devices. This ability is particularly useful when networks have to be adapted to changing traffic volumes of different applications runnin...

Software-Defined Networking (SDN) has attracted attention along with the popularization of cloud environment and server virtualization. In SDN, the control plane and the data plane are decoupled so that the logical topology and routing control can be configured dynamically depending on network conditions. To obtain network conditions precisely, a network monitoring mechanism is necessary. In th...

Software Defined Networking (SDN) defines a network architecture in which the control plane is managed by a logically centralized controller, and thus configuration updates occur frequently. We have recently introduced an approach that uses time-based configuration updates, allowing to simplify complex update procedures and to minimize transient effects caused by configuration changes. This pap...

متن کاملA Comprehensive Security Analysis Checksheet for OpenFlow Networks
Software-defined networking (SDN) enables the flexible and dynamic configuration of a network, and OpenFlow is one practical SDN implementation. Although it has been widely deployed in actual environments, it can cause fatal flows. In this paper, we consolidate the security threats to OpenFlow mentioned in previous work and introduce a new security checksheet that includes risk assessment metho...
