Program Synthesis for Programmable Data Planes: Generating P4 code by input-output examples

An all-important step in the ambitious pursuit towards autonomous networks has been the introduction of Software Defined Networking which has advocated the concept of separating a network’s control plane from the data plane and creating a programmable controller with a wider view of the network. This innovation proved to be very promising, but...

Controller-Related Security Risks and Vulnerabilities in Software-Defined Networking

Software-Defined Networking (SDN) is a relatively new networking paradigm that proposes to separate the control and the data logic in networks. The control logic is centralized in a controller, which allows for a programmable network. SDN is promising but also intro- duces some critical security vulnerabilities to networks. This work proposes a...

Exploitation of P4 Programmable Switch Networks

P4 programmable data-planes provide operators with a flexible method to set up data-plane forwarding logic. To deploy networks with confidence, a switch's forwarding logic should correspond with its intended behavior. Programs loaded onto programmable data-planes don't necessarily go through as much testing as traditional fixed-function devices...

Online Survivability in Software Defined Elastic Optical Networks

With the high and varying demands for network bandwidth, Elastic Optical Networks (EON), as a promising solution for future optical transport networks, have been getting increased attention due to its flexibility and efficiency. As a huge amount of data is transformed over these networks, even short failures will lead to major data loss. Network...

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...

Value creation through network infrastructure automation: The Software-Defined Networking Technology and its business model from the IT service provider’s perspective

Our research is exploring how the computer network technology of Software-Defined Networking (SDN) can benefit an IT service provider. SDN is a novel technology that is capable of managing a whole network based on a single centralized entity. As a result an SDN enabled network becomes more flexible, automatable and programmable to satisfy users’...
