yep, cisco routers can handle QOS, TOS, rate limiting and
the like. the feature you would like to have from it most likely would
be detailed data/log storage and history.
this if for storing
history, logs and graphs,
bandwidth usage, active
pipes,channels,rules,protocols and hosts etc. etc.
for future references and statistical
analysis.
if you have a budget, allot bandwdith
manager and packeteers equipment would do most of the stuff for you. i prefer
allot - works great with mycase. the allot that we have had billed
us $12,000. :( it also
sniffs,saves and analyze current active network packets to define customized
ports and protocols while youre sleeping so you can squeeze and control them
immediately and more. all this can be done via CLI and browser.
i did indirect/direct HTTP content filtering and redirection from router
level to cisco content and cache manager device. equipment price $3000 :(.
but it was limited of 1GB of storage and logs - not
satisfied, prefer and redirected back to wonderful server squid
and related plugins. i got me the whole 80GB raided harddisk capacity just for
that case. happy with that.

Hello Rogelio,
Agreed here, QoS and traffic shaping is the way to go IMHO. If I had to
pick one over the other, I'd definitely pick HTB over CBQ and attach a
stochastic fair queueing discipline at the leaves of each class. Works
great. Furthermore, my colleagues and I have consistently experienced
strange behavior from CBQ.
By the way, I've been meaning to replace one of my organization's main
PC routers with a cisco router. Problem is, this is where most of my HTB
scripts and content filtering resides. I know this is OT, but I'd like
to take this opportunity to ask if anyone here has had experience with
QoS in IOS? Specifically, I'm wondering if it's capable of everything
HTB is capable of doing. Admittedly, I still have to read up on this
particular IOS function thoroughly. Any feedback and gotchas will be
greatly appreciated though.
-Paul
