Network load test equipment

I'm looking for equipment that can be used to load test network equipment
such as switches, routers, firewall, and load balancers with pre-defined
traffic patterns at differing rates. Ideally, this is only something I
think I'll need 2-3x a year, so purchasing is not necessarily justifiable.
I'd prefer to rent. What products have you used? Where did you get them

I need to be able to run pre-defined traffic patterns at various rates, in
excess of 10Gbps in most cases.


You can't go wrong with IXIA.


We've used Spirent with a lot of success. They have a good lease program, too:

I've used Spirent, IXIA and Anritsu test gear and I prefer the Anritsu boxes, even if they are a tad more complicated to configure. There are places that you can rent stuff like that (I've rented OTDRs in the past) but the details escape me.
