Abstract:
Border Gateway Protocol (BGP) forms the foundation for routing in the Internet. More recently, BGP has made serious inroads into data centers on account of its scalability, extensive policy control, and proven track record of running the Internet for a few decades. Data center operators are known to use BGP for routing, often in different ways. Yet, because data center requirements are very different from the Internet, it is not straightforward to use BGP to achieve effective data center routing.
In this paper, we present Facebook's BGP-based data center routing design and how it marries data center's stringent requirements with BGP's functionality. We present the design's significant artifacts, including the BGP Autonomous System Number (ASN) allocation, route summarization, and our sophisticated BGP policy set. We demonstrate how this design provides us with flexible control over routing and keeps the network reliable. We also describe our in-house BGP software implementation, and its testing and deployment pipelines. These allow us to treat BGP like any other software component, enabling fast incremental updates. Finally, we share our operational experience in running BGP and specifically shed light on critical incidents over two years across our data center fleet. We describe how those influenced our current and ongoing routing design and operation.

Das andere Webseiten auch betroffen sind, kann man hier: https://downdetector.com/ sehen. Das ist aller Wahrscheinlichkeit nach die Überlastung der DNS Server die ich oben beschrieben habe. Es rufen derzeit einfach viel zu viele Menschen (Computer, Smartphones) bei der Auskunft (DNS Server) an um die Nummer (IP Adresse) von Google etc zu bekommen.
Da die Anrufer die Nummer nicht bekommen, legen sie wieder auf und rufen kurz danach wieder an. Würde jetzt gerne bei Facebook Fliege an der Wand spielen, super spannend. |
