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...

Investigating current state Security of OpenFlow Networks: Focusing on the control-data plane communications

Software-Defined Networking (SDN) is the emerging paradigm that breaks vertical integration in networks, separating the network’s control logic from the underlying network devices such as routers and switches.<br/>The decoupling of this data plane and control plane, there is need for a new communication channel which is used for the communication...

Delftvisor: A network hypervisor for Openflow 1.3: Network virtualization for Openflow 1.3

Openflow is the emerging standard for Software Defined Networking, it allows users to perform routing and run their applications on the network. Such applications can perform diverse tasks such as making Quality of Service guarantees and monitoring/firewalling the network.<br/><br/>Most companies don't actually own datacenters and servers...

Providing End-to-end Bandwidth Guarantees with OpenFlow

QoS (Quality of Service) control is an important concept in computer networking as it is related to end user experience. End-to-end QoS guarantees, in particular, can give firm guarantees to end hosts. Unfortunately, it has never actually been used on the Internet since it was deemed too complicated. With the emergence of Software Defined...

SDN Controller Robustness and Distribution Framework

SDN improves network flexibility which is constrained by network protocol in a conventional network by decoupling the control plane and the data plane of the network. This is the reason why many companies and universities migrate their network to SDN, there will be more SDN network in the future. Yet SDN network mainly depends on the controller...

Network Monitoring with Software Defined Networking: Towards OpenFlow network monitoring

Network monitoring is becoming more and more important as more Internet Service Providers and Enterprise networks deploy real-time services, like voice and video. Network operators need to have an up-to-date view of the network and to measure network performance with metrics like link usage, packet loss and delay, in order to assure the quality...
