ISR4431-v/K9 ISR4431-V/K9 integrated router combines high-performance, scalability, VOIP and smart router is made to run multiple services. This is the only router in industry separates control data and services planes, so the benefits are numerous. With pay-as-you-grow performance, you can increase forwarding capacity when needed, you only pay for the performance you need. The ISR4431-V/K9 runs multi-core, multi-threaded advanced Voice IOS-XE operating system to enable both WAN link security and VOIP services. Full featured WAN optimization with that run native on the motherboard without affecting performance, management and other capabilities. According to the scalability, ISR 4431 designed as a layer 7 router basically, the advanced network services enable the branch to utilize the WAN intelligently is really what ISR 4400 series all about. The Cisco ISR 4431 is the ultimate application delivery platform to mid-size or even large branch offices. This is literally routing redefined. Table 4 shows the comparison chart.
