Systematically testing OpenFlow controller applications

Jennifer Rexford, Dejan Kostic, Marco Canini, Maciej Leszek Kuzniar, Peter Peresini

The emergence of OpenFlow-capable switches enables exciting new network functionality, at the risk of programming errors that make communication less reliable. The centralized programming model, where a single controller program manages the network, seems ...

OF.CPP: Consistent Packet Processing for OpenFlow

Dejan Kostic, Nedeljko Vasic, Marco Canini, Maciej Leszek Kuzniar, Peter Peresini

This paper demonstrates a new class of bugs that is likely to occur in enterprise OpenFlow deployments. In particular, step-by-step, reactive establishment of paths can cause network-wide inconsistencies or performance- and space-related inefficiencies. Th ...

A SOFT Way for OpenFlow Switch Interoperability Testing

Dejan Kostic, Marco Canini, Maciej Leszek Kuzniar, Peter Peresini

The increasing adoption of Software Defined Networking, and OpenFlow in particular, brings great hope for increasing extensibility and lowering costs of deploying new network functionality. A key component in these networks is the OpenFlow agent, a piece o ...

Insomnia in the Access or How to Curb Access Network Related Energy Consumption

Dejan Kostic, Marco Canini

Access networks include modems, home gateways, and DSL Access Multiplexers (DSLAMs), and are responsible for 70-80% of total network-based energy consumption. In this paper, we take an in-depth look at the problem of greening access networks, identify root ...

Automating the Testing of OpenFlow Applications

Jennifer Rexford, Dejan Kostic, Marco Canini

Software-defined networking, and the emergence of OpenFlow-capable switches, enables a wide range of new network functionality. However, enhanced programmability inevitably leads to more software faults (or bugs). We believe that tools for testing OpenFlow ...

Online Testing of Federated and Heterogeneous Distributed Systems

Dejan Kostic, Dejan Novakovic, Marco Canini, Vojin Jovanovic

DiCE is a system for online testing of federated and heterogeneous distributed systems. We have built a prototype of DiCE and integrated it with a BGP router. DiCE quickly detects three important classes of faults, resulting from configuration mistakes, po ...

Finding Almost-Invariants in Distributed Systems

Dejan Kostic, Maysam Yabandeh, Marco Canini

It is notoriously hard to develop dependable distributed systems. This is partly due to the difficulties in foreseeing various corner cases and failure scenarios while implementing a system that will be deployed over an asynchronous network. In contrast, r ...

Evolution of Cache Replacement Policies to Track Heavy-Hitter Flows

Marco Canini

Several important network applications cannot easily scale to higher data rates without requiring focusing just on the large traffic flows. Recent works have discussed algorithmic solutions that trade-off accuracy to gain efficiency for filtering and track ...
