Looking for comments/experiences/war stories on testing products, such as Smartbits, Ixia, Adtech, Agilent, and Ganymede. Desired functionality: L2: 10/100/1000 Ethernet, ATM, FR, POS, PPPoX session generation L2.5: MPLS, MPLS-TE L3: BGP, OSPF, RSVP, Diff-Serv L4-7: closed-loop testing (i.e., effects of TCP windowing and other types of flow control), VoIP, streaming media, etc. Not entirely happy with current vendors... Smartbits seems ok for L2, but L3 sucks, often too cumbersome to be productive, and I found some descrepancies and reporting problems with Smartbits, which makes me not want to trust it. Agilent seems to be good at L3, but lacks L2 testing capabilities. Ganymede is good if you want to test application functionality. Past experience with Adtech was L2 only. No clue who makes anything decent to test MPLS, although I believe Agilent does. Experience with the current vendor market is that they all have their strengths, so you really need a mixture of products to do adequate testing. Just curious if others have similar experiences. Off-list replies welcomed...
