It cause my headache while writing content-based scheduler for ktcpvs
inside the kernel, because it is complicated to specify this kinds of
rules inside the kernel.
It will be better if we write content-based scheduler for ktcpvs in
user-space. IMHO, it might be not necessary to write user-space scheduler
for IPVS, because it doesn't parse the content of packets.
Dynamic-feedback weight-adaption algorithm will give the scheduler more
information about the server status, it is simple and fast, and can make
servers well balanced too. :)
