Cisco’s integrated IOS + WAAS appliances are the only way to go; the old standalone WAVE devices don’t make it anymore. IOS integration comes with both incredible value and a ton of baggage. Picking Cisco for network optimization is only a good choice if you want Cisco for every part of branch networking. The good news is that the WAAS and IOS combination on ISR hardware delivers a strong set of services including Call Manager Express for VoIP along with wireless and LAN switching options. Would we pick WAAS all by itself for optimization? Definitely not. But if you’re going down the ISR path in the branch, adding WAAS gives huge value without disruption.
