SFA: Stateful Forwarding Abstraction in SDN Data Plane

by Shuyong Zhu , Jun Bi , Chen Sun
"... Abstract Software Defined Networking (SDN) is a new network architecture where network control is decoupled from forwarding and is directly programmable. However, existing techniques provide limited support for stateful forwarding in SDN data plane. Relying on the controller for all state maintaini ..."

No silver bullet: Extending SDN to the data plane

by Anirudh Sivaraman, Keith Winstein, Suvinay Subramanian, Hari Balakrishnan - in ACM SIGCOMM HotNets Workshop , 2013
"... The data plane is in a continuous state of flux. Every few months, researchers publish the design of a new high-performance queueing or scheduling scheme that runs inside the network fabric. Many such schemes have been queen for a day, only to be surpassed soon after as methods — or evaluation metri ..."

Management Patterns: SDN-Enabled Network Resilience Management

by Paul Smith, Alberto Schaeffer-filho, David Hutchison, Andreas Mauthe
"... Abstract—Software-defined networking provides abstractions and a flexible architecture for the easy configuration of network devices, based on the decoupling of the data and control planes. This separation has the potential to considerably simplify the im-plementation of resilience functionality (e. ..."

Optimizing the migration of virtual computers

by Constantine P Sapuntzakis , Ramesh Chandra , Ben Pfaff , Jim Chow , Monica S Lam , Mendel Rosenblum - In Proceedings of the 5th Symposium on Operating Systems Design and Implementation , 2002
"... Abstract This paper shows how to quickly move the state of a running computer across a network, including the state in its disks, memory, CPU registers, and I/O devices. We call this state a capsule. Capsule state is hardware state, so it includes the entire operating system as well as applications ..."

as applications and running processes. We have chosen to move x86 computer states because x86 computers are common, cheap, run the software we use, and have tools for migration. Unfortunately, x86 capsules can be large, containing hundreds of megabytes of memory and gigabytes of disk data. We have developed

Measuring Control Plane Latency in SDN-enabled Switches

by Keqiang He, et al. , 2015
"... Timely interaction between an SDN controller and switches is crucial to many SDN applications—e.g., fast rerouting during link failure and fine-grained traffic engineering in data centers. However, it is not well understood how the control plane in SDN switches impacts these applications. To this en ..."

Model Based Black-Box Testing of SDN Applications

by unknown authors
"... The quality of control plane applications determines relia-bility of the Software-Defined Networking (SDN). The risk of bugs and challenges for testing actually have been in-creased due to the programmability of SDN. In this paper, we propose a model based black-box testing method for S-DN applicati ..."

On Using a SDN-based Control Plane in 5G Mobile Networks

by Toktam Mahmoodi, Srini Seetharaman
"... Today’s mobile operators face significant challenges with handling the ever-increasing volume of mobile data traf-fic. With new mobile communication standards, like 4G/LTE, the mobile backhaul architecture has a clear split of a packet-only dataplane and a management plane. Although this new backhau ..."

An Architectural Proposal for an SDN based Data Centre:

by Sarla Sharma, Manu Sood
"... Software Defined Networking (SDN) is an important approach to network design which uses software to enable networked systems to expand data flow control. Data centre is a facility used to house computer systems and associated components, such as telecommunication equipments, storage systems and back ..."

and backup systems. Networks are a critical component of data centres for getting efficient outputs / results. SDN presents a new architecture that separates the network control plane from the data plane, allowing a centralized controller (or set of controllers) to define forwarding behaviour. These networks

Figure 1: Segregated nature of WANs, with network devices grouped in layers managed by their forwarding technology. Traffic Optimization in Multi-Layered WANs using SDN

by Henrique Rodrigues, Inder Monga, Abhinava Sadasivarao, Sharfuddin Syed, Chin Guok, Eric Pouyoul, Chris Liou, Tajana Rosing
"... Abstract — Wide area networks (WAN) forward traffic through a mix of packet and optical data planes, composed by a variety of devices from different vendors. Multiple forwarding technologies and encapsulation methods are used for each data plane (e.g. IP, MPLS, ATM, SONET, Wavelength Switching). Des ..."
