Automatic test packet generation

Hongyi Zeng, Peyman Kazemian, George Varghese, Nick McKeown
2012 Proceedings of the 8th international conference on Emerging networking experiments and technologies - CoNEXT '12  
The model is used to generate a minimum set of test packets to (minimally) exercise every link in the network or (maximally) exercise every rule in the network.  ...  We find that a small number of test packets suffices to test all rules in these networks: For example 4000 packets can cover all rules in Stanford backbone network while 54 is enough to cover all links  ...  Debugging networks is only becoming harder as networks are getting bigger (modern data centers may contain 10,000 switches, a campus network may serve 50,000 users, a 100Gb/s long haul link may carry 100,000  ...

Scaling data-plane logging in large scale networks

Ahsan Arefin, Ahmed Khurshid, Matthew Caesar, Klara Nahrstedt
2011 2011 - MILCOM 2011 Military Communications Conference  
In this paper, we propose a scalable and reliable framework to monitor fine-grained data-plane behavior within a large network.  ...  We give a feasible architecture for a distributed logging facility, a tree-based data structure for log compression and show how this logged information helps network operators to detect and debug anomalous  ...  (e.g., transient/intermittent faults, convergence events, instability) at the data plane has remained something of a black art.  ...

Neighborhood View Consistency in Wireless Sensor Networks

Arshad Jhumka, Luca Mottola
2016 ACM transactions on sensor networks  
We prove that, in the presence of transient faults, NVC is impossible to solve with any PCDs, and thus define two weaker specifications of the problem.  ...  We prove that the problem cannot be solved in an asynchronous system using any of Chandra and Toueg's failure detectors.  ...  This work was partly supported by the Projects "Zero-energy Buildings in Smart Urban Districts" (EEB), "ICT Solutions to Support Logistics and Transport Processes" (ITS), and "Smart Living Technologies  ...

Renaissance: Self-Stabilizing Distributed SDN Control Plane [article]

Marco Canini, Elad Michael Schiller Université catholique de Louvain, University of Vienna
2019 arXiv   pre-print
In particular, we develop algorithms for an in-band and distributed control plane for SDNs, called Renaissance, which tolerate a wide range of (concurrent) controller, link, and communication failures.  ...  By introducing programmability, automated verification, and innovative debugging tools, Software-Defined Networks (SDNs) are poised to meet the increasingly stringent dependability requirements of today's  ...  Part of this research was supported by the Danish Villum Fonden blokstipendier project Reliable Computer Networks (ReNet). This research is (in part) supported by  ...

2015 Proceedings of the IEEE  
To make matters even more difficult, current networks are also vertically integrated: the control and data planes are bundled together.  ...  It is both difficult to configure the network according to predefined policies, and to reconfigure it to respond to faults, load and changes.  ...  In addition, we would like also to acknowledge the several contributions from the community, namely from Aurel A.

Automatic reconfiguration in Autonet

Thomas L. Rodeheffer, Michael D. Schroeder
1991 ACM SIGOPS Operating Systems Review  
Switch hardware uses the destination address in each packet to determine the proper outgoing link for the next step in the path from source to destination.  ...  This paper describes the fault monitoring and topology acquisition mechanisms that are central to automatic reconfiguration in Autonet. 2 100 hosts.  ...  Packets are regular data packets whereas signals are transported in link protocols below the level of packet traffic.  ...
