# This does the right thing with ipv6 traffic.
|
||||
# It also tries to leverage diffserv to some sane extent. In particular,
|
||||
# the 'priority' queue is limited to 33% of the total, so EF, and IMM traffic
|
||||
# cannot starve other types. The rfc suggested 30%. 30% is probably
|
||||
# a lot in today's world.
|

|

# Flaws
|

# Many!

# This does the right thing with ipv6 traffic.
|

# It also tries to leverage diffserv to some sane extent. In particular,

# the 'priority' queue is limited to 33% of the total, so EF, and IMM traffic
|

# cannot starve other types. The rfc suggested 30%. 30% is probably

# a lot in today's world.
