It is old slides ;-) History: At the beginning we would like to replace the Network VM plugin by wraping the POSIX socket layer through Alien. At that time, we chose Alien because it supports callbacks. And it was a nightmare to use Nativeboost because it required a special VM (with NB plugin) but that VM had not some Network primitives about ipv6 and UDP. Now things are much much better ;-) one VM and everything inside. But now we focus on the image part (Network API) that still uses the plugin as backend (no need for Alien at all). When it will work we will implement another backend with NB probably. I know that Igor started one. But I would to investigate wrapping ZeroMQ (I saw some mails about that).
