XR itself provides abstractions on top of QNX and Linux, so devs working on platform independent code are not really affected.
- tyingq 8y agoMaybe also because things like DPDK (or similar) made it possible for Linix to play at that scale?
- Cyph0n 8y agoThe routers I am talking cannot do packet processing on the CPU. We are talking about 3.2 Tbps per linecard with 10 linecards per router. All data plane activity is done on custom in-house ASICs called network processors (NPs). The CPU only handles control plane traffic and general administration.
