As technology progresses, the difference between routers and switches is becoming less clear. Essentially, routers are Layer 3 (L3) products that connect networks. A common scenario is connecting a small business network to the Internet via DSL. Switches are L2 devices that interconnect client devices within a network. Generally, routers rely on computation to send traffic using sophisticated software, offering intelligence at the expense of throughput. Switches, by comparison, rely upon mostly predefined hardware configurations to send traffic at the fastest possible rate. Today's routers typically include Layer 2 switching capability, and many of today’s switches have L3 routing capability. Routers developed by Cisco, the supplier of 90% of the industry's routers, have improved significantly in function and performance and Cisco now makes an extensive portfolio that features routers designed to handle the needs of users from households to the world's largest ISPs.
The latest ISR routers from Cisco offer the speed and integrated functionality to support data voice and video as well as virtualization while also providing fault tolerance, remote management, seamless scalability, and advanced security and compliance. Cisco's ISR routers enable your company to build a solid foundation for an IT environment that can grow seamlessly as you hire more employees, establish extra sites, configure new capabilities, give access to your network to clients and partners, and support an expanding mobile workforce. Progent’s Cisco certified CCIE network engineers can provide fast and affordable remote support to assist you to select, configure, administer, upgrade, and troubleshoot Cisco's latest router technology and can help you to maintain your legacy routers or migrate efficiently to Cisco’s current router products.
