Samer Abdel-Hafez joined the FiberRing network team in December 2013 as Network Design Engineer. Samer’s responsibilities within the team include planning capacity for the large traffic volume of FiberRing, arranging interconnections in new locations and markets, designing advanced ad-hoc solutions for the FiberRing network and customers and advise the Network support team on day to day issues. Abstract: FiberRing operates one of the largest content networks in the world, peaking at over 2 Tb/s. In order to facilitate troubleshooting, detect attacks and saving important data as router configurations, we implement a series of tools mostly implemented in house or open source. The key point of this presentation is to describe how FiberRing is using these tools for: monitoring: FiberRing makes extensive use of Opsview (Nagios) and NMIS. We utilise Opsview for alerts and reporting and NMIS for detailed traffic analysis. capacity planning: FiberRing choose PMACCT as netflow collector software and implemented an in house front-end solution that helps us locate strategic peering partners and explore ways to reduce the costs to deliver our content. DDOS attacks detection: As every large hosting provider, we are regularly target of DDoS attacks. We implement a set of linux boxes running running nfcapd to collect traffic flows with 1 minute/per host granularity. This gives us great flexibility and incredibly valuable data to quick detect attacks and take corrective actions. routers’ configuration backups: FiberRing is actively involved in the development of Oxidized, an innovative configuration backup tool which poses itself as rancid replacement.
