Overview (CISCO2811)

The Cisco 2800 Series provides significant additional value compared to prior generations of Cisco routers at similar price points by offering up to a fivefold performance improvement, up to a tenfold increase in security and voice performance, new embedded service options, and dramatically increased slot performance and density while maintaining support for most of the more than 90 existing modules that are available today for the Cisco 1700, Cisco 2600, and Cisco 3700 Series.The Cisco 2800 Series features the ability to deliver multiple high-quality simultaneous services at wire speed up to multiple T1/E1/xDSL connections. The routers offer embedded encryption acceleration and on the motherboard voice digital-signal-processor (DSP) slots; intrusion prevention system (IPS) and firewall functions; optional integrated call processing and voice mail support; high-density interfaces for a wide range of connectivity requirements; and sufficient performance and slot density for future network expansion requirements and advanced applications.

On what basis do we select a router

On what basis do we select a router?
ex:- Cisco 2811, 2821, 1800 series ... Yeah..It depends how many people are plugging into your router, the higher models have higher amounts of ports, and more of everything. If you're just looking for a home router, I suggest the 800 series.
