But rpd is still 100% flat, run-to-completion. You can almost think of FreeBSD as hypervisor and rpd as virtual pc on top of it, it has own scheduler, memory management etc. IOS-XE is almost same architecture, Linux with flat ios as process. Otoh iosd is already slightly distributed and runs like 5 threads (but no meaningful routing work is distributed). Easy step#2 would be to give rpd affinity to push it on its own dedicated core. Hard step#3 is to make rpd use multiple cores. JNPR seems to choose to DIY inside rpd and just launch threads. I personally would like to see rpd distributed to multiple OS processes, and capitalise more on FreeBSD's memory management and scheduling. But I'm not sure how to handle the IPC efficiently without large cost in data duplications across processes. -- ++ytti _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
