Last month it was Catalyst 9000 switches, and this month its routers. Yes, my project engineering staff have had a surprising amount of inquiries regarding routers.\nRouters vital to enterprise networks\nWhen looking at distribution for an enterprise network, well-planned routing is the key to success. Routers can be absolutely vital for networks, as they connect a large amount of worksites within one large, umbrella-like network. At the enterprise level, they provide redundant paths, connect ISPs, and can translate data between different media.\n\nIn addition to routing packets to the right place, routers will select alternate routes when a link is compromised or traffic is heavy. Routers, Cisco routers in particular, work as a default gateway. And Cisco\u2019s 4000 router family, while it has been out for a while, is worth another look.\nCisco's 4000 router family is a serious upgrade from the older 1900\/2900\/3900 families \u2014 but not so different that they blow your mind.\nWhat\u2019s new in the Cisco 4000 router series?\nThe Cisco 4000 series has the following features:\n\nBroad range of performance levels \u2013 from 35 Mbps to 2 Gbps\nAll but the smallest 4221 model have OIR (online insertion and removal) capability for the NIMs\nSignificant increase in max RAM (up to 16 gig on some models)\nUtilize the same IOS software feature sets\/licensing model as the older ISR G2s\n\nHere\u2019s the list of available models from Cisco:\n\nAnd here\u2019s a table that shows performance levels, port, and module count:\n\nNotice the row labelled \u201caggregate throughput\u201d? There are two performance numbers per router \u2013 Cisco has taken the performance licenses originally found on their mighty ASR router line and adapted them. If you purchase any one of these routers, they will come standard with the lower of the two performance numbers. Later on as your requirements grow, you can purchase a performance upgrade license from Cisco and voila! Your router now is faster.\nThese routers have many other features and capabilities.

Having the right Cisco router will let you not only manage network switches, but it will give you more time to switch your many hats throughout the day.\nWhether you\u2019re babysitting the call center, helping the president get his or her WebEx to work, or planning how your network can keep up with your company\u2019s growth, selecting the right Cisco router makes all the difference.
