No problem.

Hello,

	I''m playing with tc, htb, and other QoS features on an old pc I have.
The PC runs, by now, a shrinked version of Debian Woody, with patched
versions of kernel 2.4.18 and iproute in order to support HTB.

	What i''m wondering is if with a AMD 100Mhz (stealed from a museum ;-),
16Mbps RAM i can do bandwidth management to 20 network hosts, which
connect wirelessly (not all, but mostly of these) sharing a wireless
link of 800 kbps (kbit in tc grammar) and i''m simulating an external
interfase of 256 kbps. 

	The ASCII art is as follows:

	    ____________
         e0|            |e1   ____      _________            to client
   --------| Linuxbox   |----|HUB |----|Wireless |  800kbps  devices
           | 100MHz16MB |    |____|    |AP       |  ) ) ) )  (PC,Hheld)
           |____________|       |      |_________|
                                |
                                `------ Wired Network


Where e0 and e1 means eth0 and eth1.
eth0 works at 256kbps, and eth1 might receive traffic at 800kbps as much
(from Wireless Access Point) or at 10mbps from the wired network.

------- is wire cable
) ) ) ) is air link (aka wireless)



	All this stuff is just for asking if i could use the "old museum" AMD
100MHz for BwM of 800 kbps average traffic.

	This old PC also works as testbed for mi diskless linux test (ramdisks,
initrd setups, etc) so, it is possible that it will work with only 8MB
of RAM if I use 8MB for the ramdisk. So, consider both cases (8 and 16
of RAM).

	Thanks.
