High performanceCisco ISR 4431 features multicore architecture with internal services plane and remote installation of application-aware services, which run identically to their counterparts in dedicated appliances. Backplane architecture supports high-bandwidth module-to-module communication at high speeds.Lower WAN expendituresEmbedded IWAN solution is designed for creating lower-cost, business-class Internet connections.Superior and secure user application experiencesSecure boot feature performs hardware-based authentication of the bootloader software to prevent malicious or unintended software from booting on the system. Code signing verifies digital signatures of executables prior to loading to prevent execution of altered or corrupted code. Hardware authentication protects against hardware counterfeiting by using an on-board tamper-proof silicon, including field replaceable modules. If authentication fails, the module is not allowed to boot.IT consolidation, space savings, and improved total cost of ownership (TCO)Single converged branch platform integrates routing, switching, virtual server, storage, security, unified communications, WAN optimization, and performance management tools.Business continuity and increased resiliencyISR 4431 supports dual integrated power supplies for backup. It features modular network interfaces with diverse connection options for load-balancing and network resiliency and modular interfaces with online removal and insertion (OIR) for module upgrades without network disruption.
