In-Band Synchronization for Distributed SDN Control Planes∗

by Liron Schiff, Stefan Schmid, Petr Kuznetsov
"... Control planes of forthcoming Software-Defined Networks (SDNs) will be distributed: to ensure availability and fault-tolerance, to improve load-balancing, and to reduce over-heads, modules of the control plane should be physically distributed. However, in order to guarantee consistency of network op ..."

operation, actions performed on the data plane by different controllers may need to be synchronized, which is a nontrivial task. In this paper, we propose a synchronization framework for control planes based on atomic transactions, implemented in-band, on the data-plane switches. We argue that this in-band

Fast Recovery in Software-Defined Networks

by Niels L. M. Van Adrichem, Benjamin J. Van Asten, O A. Kuipers
"... Abstract—Although Software-Defined Networking and its im-plementation OpenFlow facilitate managing networks and enable dynamic network configuration, recovering from network failures in a timely manner remains non-trivial. The process of (a) detecting the failure, (b) communicating it to the control ..."

Fast IP network recovery using multiple routing configurations

by Amund Kvalbein, Audun Fosselie Hansen, Stein Gjessing, Olav Lysne - in INFOCOM 2006. 25th IEEE International Conference on Computer Communications. Proceedings
"... Abstract — As the Internet takes an increasingly central role in our communications infrastructure, the slow convergence of routing protocols after a network failure becomes a growing problem. To assure fast recovery from link and node failures in IP networks, we present a new recovery scheme called ..."

Fast Recovery Protocol for Database and Link Failures in Mobile Networks*

by Govind Krishnamurthi, Stefan Chessa, Arun K. Somanil
"... An important issue in the design of fu ture Per-sonal Communicat ion Services ( P C S) networks i s the efficient management of location information. T h e current IS-41 standard P C S architecture uses a centralized database, the Home Location Register ( H L R) , t o store service and location in ..."

mobiles immediately as mobiles could have changed their location during the H L R ' s failure. Fast recovery f r o m a failure of the H L R is hence important. A link failure in the network could partition the network resulting in a loss of location updates f r o m mobiles affected by the failed link

Fast Recovery From Link Failures in Ethernet Networks

by Abishek Gopalan, Srinivasan Ramasubramanian , 2013
"... Fast-recovery from link failures is a well-studied topic in IP networks. Employing fast-recovery in Ethernet networks is complicated as the forwarding is based on destination MAC addresses, which do not have the hierarchical nature similar to those exhibited in Layer 3 in the form of IP-prefixes. M ..."

single link failures in Ethernet networks. All three approaches provide guaranteed recovery from single link failures. The approaches differ in the technologies required for achieving fast recovery, namely VLAN rewrite and/or mac-in-mac encapsulation. We study the performance of the approaches developed

Detour Planning for Fast and Reliable Failure Recovery in SDN with OpenState

by Antonio Capone, Carmelo Cascone, Ro Q. T. Nguyen
"... Abstract—A reliable and scalable mechanism to provide pro-tection against a link or node failure has additional requirements in the context of SDN and OpenFlow. Not only it has to minimize the load on the controller, but it must be able to react even when the controller is unreachable. In this paper ..."
Abstract - Add to MetaCart
. In this paper we present a protection scheme based on precomputed backup paths and inspired by MPLS “crankback ” routing, that guarantees instantaneous recovery times and aims at zero packet-loss after failure detection, regardless of controller reachability, even when OpenFlow’s “fast-failover ” feature cannot

978-1-4799-0683-3/13/$31.00 ©2013 IEEE 1 Using Transparent WDM Metro Rings to Provide an Out-of-Band Control Network for OpenFlow in MAN

by Rafael Sánchez, José Alberto Hernández, David Larrabeiti , 2013
"... OpenFlow is a protocol that enables networks to evolve and change flexibly, by giving a remote controller the capability of modifying the behavior of network devices. In an OpenFlow network, each device needs to maintain a dedicated and separated connection with a remote controller. All these connec ..."
Abstract - Add to MetaCart
these connections can be described as the OpenFlow control network, that is the data network which transports control plane information, and can be deployed together with the data infrastructure plane (in-band) or separated (out-of-band), with advantages and disadvantages in both cases. The control network is a
