Journal ArticleDOI
OpenFlow: Meeting carrier-grade recovery requirements
TL;DR: This paper adds the recovery action in the switches themselves so that the switches can do recovery without contacting the controller, and shows that this approach can achieve recovery within 50ms in a large-scale network serving many flows.
Proceedings ArticleDOI
Enabling fast failure recovery in OpenFlow networks
TL;DR: This work proposes the addition of a fast restoration mechanism in OpenFlow and evaluates the performance by comparing the switchover time and packet loss to existing restoration options in a current OpenFlow implementation.
Proceedings ArticleDOI
Software defined networking: Meeting carrier grade requirements
TL;DR: It is shown that Openflow can restore traffic quite fast, but its dependency on a centralized controller means that it will be hard to achieve 50 ms restoration in large networks serving many flows, and protection will be required in carrier grade networks.
Proceedings Article
Fast failure recovery for in-band OpenFlow networks
TL;DR: This paper explains how failure recovery can be deployed in a large-scale network serving many flows, and applies two well-known recovery mechanisms-restoration and protection- for the control and the data traffic, and runs extensive emulation experiments.
Journal ArticleDOI

TL;DR: The OFELIA testbed as discussed by the authors is a multi-layer, multi-technology and geographically distributed Future Internet testbed facility, where the network itself is precisely controlled and programmed by the experimenter using the emerging OpenFlow technology.
