Time (Ugur Kaynar)
Title: VeriFlow: Verifying Network-Wide Invariants in Real Time

Presenter: Ugur Kaynar

Abstract:
This presentation covers the paper "VeriFlow: Verifying Network-Wide  
Invariants in Real Time" [1]. The paper addresses the problem of checking  
network-wide invariants, allowing detection and prevention of bugs in the  
network data plane of software defined networks. The key novelty is that  
VeriFlow allows this verification to be carried out in real time.

Paper Abstract:
Networks are complex and prone to bugs. Existing tools that check network  
configuration files and the data-plane state operate offline at timescales  
of seconds to hours, and cannot detect or prevent bugs as they arise.
Is it possible to check network-wide invariants in real time, as the  
network state evolves? The key challenge here is to achieve extremely low  
latency during the checks so that network performance is not affected. In  
this paper, we present a design, VeriFlow, which achieves this goal.  
VeriFlow is a layer between a software-defined networking controller and  
network devices that checks for network-wide invariant violations  
dynamically as each forwarding rule is inserted, modified or deleted.  
VeriFlow supports analysis over multiple header fields, and an API for  
checking custom invariants. Based on a prototype implementation integrated  
with the NOX OpenFlow controller, and driven by a Mininet OpenFlow network  
and Route Views trace data, we find that Veri-Flow can perform rigorous  
checking within hundreds of microseconds per rule insertion or deletion
