Cisco Network Consulting

As computer technology progresses, the distinction between router and switch products has grown blurred. Fundamentally, routers are Layer 3 (L3) devices designed to connect different networks. A typical example is connecting an office Ethernet network to the Internet. Switches are instead L2 devices that interconnect various devices that share the same network. Generally, routers rely on CPUs to move traffic based on sophisticated algorithms, offering intelligence at the cost of speed. Switches, in contrast, depend on largely fixed hardware configurations to send traffic at the fastest feasible speed. The current generation of routers typically include Layer 2 switching capability, and many modern switches have Layer 3 routing capability. Routers developed by Cisco, the producer of 90% of the industry's routers, have improved significantly in capability and speed and Cisco now offers a comprehensive portfolio that features routers engineered to meet the needs of customers ranging from households to nationwide service providers.

The latest ISR routers released by Cisco offer the performance and integrated features to support IP voice and video as well as virtual environments while also offering fault tolerance, web-based management, easy extensibility, and enhanced protection. Cisco's ISR routers allow your company to build a solid foundation for an IT network that can evolve smoothly as you add new workers, establish new offices, configure additional capabilities, extend your system to clients and partners, and build an an increasingly mobile user base. Progent’s Cisco CCIE network engineers can provide immediate and economical remote support to help your company to plan, deploy, manage, upgrade, and troubleshoot Cisco's most advanced routers and can assist you to support your legacy routers or migrate efficiently to Cisco’s newer router products.
