Cisco Expert Network Consulting

As computer technology advances, the difference between router and switch products is becoming blurred. At heart, routers are Layer 3 (L3) products designed to connect different networks. A typical example is connecting an office network to the Internet via DSL. Switches are instead Layer 2 (L2) devices that interface client devices that share the same network. Generally, routers depend on computation to send traffic using complex algorithms, offering intelligence at the cost of throughput. Switches, in contrast, depend on mostly predefined hardware configurations to forward data at the fastest feasible rate. The current generation of routers typically come with Layer 2 switches, and many of today’s switches have L3 routing functionality. Routers offered by Cisco, the producer of 90% of the world's routers, have advanced significantly in function and speed and Cisco now makes a comprehensive product line that includes routers engineered to handle the needs of customers ranging from households to the world's largest service providers.

The most recent Integrated Services Routers released by Cisco offer the performance and built-in features to manage IP voice and video as well as virtual environments while at the same time providing high availability, web-based administration, easy extensibility, and advanced security and compliance. These routers allow you to establish a firm foundation for an IT environment that can grow smoothly as you hire new workers, open extra sites, deploy additional functions, extend your network to customers and vendors, and build an an increasingly mobile user base. Progent’s Cisco CCIE network engineers offer fast and economical online support to help your company to select, deploy, manage, update, and support Cisco's most advanced routers and can help you to support your legacy routers or migrate efficiently to Cisco’s current networking solutions.
