Cisco® Intelligent Traffic Director (ITD) is an innovative solution to bridge the performance gap between a multi-terabit switch and gigabit servers and appliances. ITD is much superior than legacy solutions such as PBR, ECMP, WCCP, Port-channel, etc for service appliances and servers.  ITD is allowing customers to achieve massive CAPEX and OPEX savings. Here is a table comparing with some of the features.
