An SDN-based Architecture for network-as-a-service

NDNFlow: Software-defined named data networking

Experiences with MPTCP in an intercontinental OpenFlow network

The size and amount of e-science data sets is growing rapidly. Keeping up with the network demand in order to transfer these data sets over the Internet is a challenge. Single links do not have enough capacity anymore. Therefore we need to install more interfaces in the servers and use all available paths in the network. In this paper we...

OpenNetMon: network monitoring in openflow software-defined networks

DNSSEC Misconfigurations: How incorrectly configured security leads to unreachability

Backup rules in Software-Defined Networks

The past century of telecommunications has shown that failures in networks are prevalent. Failure recovery processes are therefore needed. Failure recovery is mainly influenced by (1) detection of the failure, and (2) circumvention of the detected failure. However, especially in SDNs where controllers recompute network state reactively, this...

Providing Bandwidth Guarantees with OpenFlow

Quality of Service (QoS) control is an important concept in computer networking, as it is related to end-user experience. While providing QoS guarantees over the Internet has long been deemed too complicated, the emergence of Software- Defined Networking (SDN), and OpenFlow as its most popular standard, may facilitate QoS control.<br/>In this...

Fast network congestion detection and avoidance using P4

Along with exciting visions for 5G communications and the Tactile Internet, the networking requirement of attaining extremely low end-to-end latency has appeared. While network devices are typically equipped with buffers to counteract packet loss caused by short-lived traffic bursts, the more those buffers get filled, the more delay is added to...
