Cisco Certified Network Consultants

As technology progresses, the distinction between a router and a switch has grown blurred. At heart, routers are Layer 3 products designed to connect networks. A typical scenario is connecting an office network to the Internet. Switches are Layer 2 (L2) devices that interface client devices that share the same network. Generally, routers rely on computation to forward traffic using complex software, offering flexibility at the cost of throughput. Switches, in contrast, rely on mostly predefined hardware designs to steer traffic at the fastest feasible speed. Today's routers usually include L2 switches, and many of today’s switches have some Layer 3 routing functionality. Routers offered by Cisco, the supplier of 90% of the world's routers, have advanced dramatically in capability and performance and Cisco now offers a comprehensive portfolio that features routers engineered to handle the needs of users ranging from households to nationwide service providers.

The most recent Integrated Services Routers from Cisco have the performance and built-in features to support data voice and video plus virtual environments while also providing fault tolerance, web-based administration, easy scalability, and advanced protection. These routers allow your business to establish a firm foundation for an IT environment that can evolve seamlessly as you hire new employees, establish new sites, configure new services, extend your network to customers and vendors, and support an an increasingly mobile user base. Progent’s Cisco qualified CCIE network consultants can provide immediate and affordable online support to help your company to plan, deploy, administer, update, and troubleshoot Cisco's most advanced router technology and can help you to support your older routers or move non-disruptively to Cisco’s current networking solutions.
