Message-Id: List-Id: References: In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: lartc@vger.kernel.org Outgoing shaping (LAN --> WAN) makes sense as your input rate to the router is at LAN speeds while its output rate is at (relatively low-bandwidth) WAN speeds. A good set of rules will provide significant performance benefits for critical apps, while relegating non-critical ones to a "best effort" basis. Shaping incoming traffic with queueing technology (WAN --> LAN) does not make much sense as queues would occur after packets have crossed a (presumably congested) WAN link, to be forwarded by the routing engine to a 10, 100 or 1,000 Mbps infrastructure. Queues in such a case add unnecessary latency and provide no real benefit. _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
