AmLight ’ s OpenFlow Sniffer dissected : Troubleshooting production networks

AmLight network was migrated to an OpenFlow approach in mid2014. Since its migration, AmLight hosted a few network testbeds, where each testbed presented different challenges to the network operation. As OpenFlow agents are new codes on the network devices, some flaws and crashes are expected. However, as AmLight is a production network, outages have to be handled right away. This paper will present AmLight’s OpenFlow Sniffer, an open source tool to be used for troubleshooting and learning purposes. Using the OpenFlow Sniffer improved the overall troubleshooting process on AmLight SDN’s network.
