Juniper Networks is developing a massive switch that could replace traditional IP (Internet Protocol) routers in the core of service-provider networks. The PTX Series Packet Transport Switch platform will combine optical and electronic technologies that today exist in separate systems with dedicated staffs. The company claims the PTX platform can cut network capital expenditures by between 40 percent and 65 percent compared with a traditional multiprotocol routing architecture. Analyst: “You would hope that this kind of reduces the cost per bit and therefore is passed down to the IT guys””]
