Network Stack Cloning Updates on FreeBSD

Dan writes "Network stack cloning patches on FreeBSD allow for multiple fully independent network stacks to simultaneously coexist in a single FreeBSD kernel. Marko Zec has prepared a latest snapshot of the patches (against 4.8-RELEASE). The latest snapshot includes (a) internal restructuring - - struct vimage is now separated in resource-specific containers, and (b) Kernel message buffers - each vimage / vprocg now has a private kernel message buffer instance. Julian Elischer gave a talk on this subject at the USENIX Annual Technical Conference (FreeNIX track) in San Antonio, TX, June 2003. Marko's slides were presented at BSDCon Europe 2002 in Amsterdam."
