Subject: [LARTC] Duplexing
Date: Mon, 09 Aug 2004 14:13:41 +0000	[thread overview]
Message-ID: <41178695.20908@ycc.com> (raw)

The recent thread titled:
    working ftp shaping, i think
provided a script example where 100Mbps was specified as the rate for a 
typical NIC.

If that NIC is connected to a switch, chances are that it runs at 
100Mbps in each direction concurrently - duplexed  Writing a rule that 
specifies a 100Mbps rate and thereby a 100Mbps ceil, limits the 
connection to half the available bandwidth.

I haven't seen anything in tc (not iptables) that addresses direction - 
inbound or outbound.
Is there a way of writing rules that take duplexing into account so that 
you end up with 2 virtual devices, each capable of 100Mbps, but the 
traffic is direction specific?
