With their souped-up engines and buckets of cash, two new router players have ambitious plans to break the two-headed tyranny of Cisco and Juniper.They feel they can sway service providers now beholden to Cisco and Juniper to their wares, built, they say, from the ground up to accommodate the millions of hosts and astounding growth of the Internet, through flexibility and financial incentives. The stability of their own financial backing doesn\u2019t hurt either.Procket Networks, which has raised close to $300 million in four years, debuted this week with programmable products and a portability plan designed to put its routing smarts on the platforms of some influential partners.A big part of Procket's strategy is to license its IP software to strategic partners to enable new applications\u00a0- such as blade server virtualization and low-end enterprise routing. The company says it already has \u201csignificant engagements\u201d with big server vendors, among others.Procket hopes the licensing strategy will attract buyers who feel Cisco\u2019s software is old and unwieldy, and Juniper\u2019s has already been surpassed by the growth of the Internet.\u201cCustomers are tired of the fact that they have to continually upgrade,\u201d Procket CEO Randall Kruep says. \u201cThey\u2019re sick of all the churn. They\u2019re tired of all the software stability issues and the 25 to 30 different versions\u201d of the same code.Debuting with Procket this week is Caspian Networks, which has also raised close to $300 million in four years. Caspian has an aggressive trade-in program to go along with the \u201cflow-based\u201d router it unveiled this week.The Caspian \u201cCORE\u201d (Capex\/Opex Reduction Enhancement) trade-up program allows network service providers trading in existing routers or ATM switches from leading manufacturers to receive credit toward purchases of Caspian\u2019s Apeiro routers. Competitive products must be currently deployed in production service provider networks to qualify for credit.The amount of credit varies and depends on the purchase price of the original equipment, the length of time it has been in service and the volume of Caspian equipment committed to under the program.
