# test_LAN_triple-isolate__piece_of_cake.qos (Cero3 Shaper)
|
|
#
|
|
# Abstract:
|
|
# This is a one band cake and ipv6 enabled shaping script for Ethernet
|
|
# gateways. This exists for the purpose of testing cake's different isolation
|
|
# options, specifically the non-directional triple-isolate feature that promises
|
|
# to finally tackle the bit-torrent hole in simple.qos.
|
|
# This specific version is supposed to be used on LAN interfaces:
|
|
# the script's ingress direction equals the internet/WAN upload direction
|
|
# the script's egress direction equals the internet/WAN download direction
|
|
#
|
|
# NOTE: Shaping on a LAN interface only affects machines connected via that
|
|
# LAN interface, so typically WIFI/WLAN traffic will not be shaped!
