I am wondering how a layer 4 switch compares to a UNIX/LINUX
server running SNMP connected to a HUB.

Could you please provide some info on what the differences would be and any other implications....

I guess some specifc things I would like to know are can I cap bandwidth to different IP addresses and can I monitor traffic to different web sites on the same IP address?

For "canned" applications like this, it is often a lot easier to go to a switch or smart router.  Especially if you want advanced routing, logging.  As a consultant I will often opt for a smart router of some sort, in the end it costs the client (in this case you) less.  Most boxes nowadays are SNMP enabled and have excellent web interfaces for configuration.

The base stuff that comes with Linux is often time consuming to configure and cryptic when you want to get into detailed configurations.

There are third party add-ons that might help you out.  For example, SQUID Proxy is a good example, and Progressive makes a nice VPN solution and firewalling solution.


I hope this helps out.

Are you sure the cost works out the same? From my research a layer 4 switch is around $20K whereas a linux box can be around $2-3K

Check which ports are open to the outside world. Helps make sure that your firewall rules are working as intended.

Check out NPI, they might have some cheaper layer 4 stuff.  I know their Layer 3 stuff is priced awesome.

You can definately monitor traffic on IPs in Linux, but I'm not sure about throttling bandwidth.  Why do you need to control the bandwidth TO IPs?

You can't just compare price when dealing with this kind of stuff.  You have to look at implementation time, support availability and ongoing maintenance.  For example, a Compaq CacheCube based on NetWares FastCache technology will out-perform a Linux box hands down and you get the wicked tech support from Compaq.

I personally am a huge advocate of using Linux, but for many applications it just isn't mature enough yet.

Can you reccomend a good switch (ideally from cisco or HP) that can cap bandwidth on a per port basis? We are under a tight budget to so something not too expensive.. Ideally it should be able to monitor traffic on a per IP basis...

Thanks alot
