This will be good for FORE, Juniper CEO: Internet needs work By Adam Gaffin Network World Fusion, 10/23/98 Atlanta - The router is the bottleneck that's holding up the Internet. At least, that's the thesis of Scott Kreins, CEO of Juniper Networks, whose product is a switch designed to replace the routers at the heart of the network. In a keynote at NetWorld+Interop, however, Kreins added that other devices and services also need to be upgraded to give the Internet the kind of reliability users now get from the voice network and to support new types of applications. Kreins gave the Internet an A+ for connectivity, a B- for reliability and a D for its ability to prioritize different types of applications. Kreins said server and database vendors have largely eliminated servers and databases as network chokepoints, through such techniques as server farms and load balancing. And the transport layer has far outpaced the rest of the network in adding capacity, he said. He said optical technology is doubling in power every 12 months, compared to the 18-month doubling seen in the components that connect to fiber backbones. Routers, which must inspect each packet for destination simply are unable to keep up with the demand on a network with 85,000 potential routing paths, he said. Add the need to inspect packets for priority and billing and the problem gets worse, he said. Rather than bits/sec, the key Internet metric should be packets/sec, he said. But even once that is fixed, making the Internet the backbone of new services will take considerable work on QoS by ISPs and vendors. QoS "actually much more complex than simply the task of painting the packet (with a priority level) at the boundary,'' he said. Also needed is agreements among ISPs to support these differing traffic levels - to work, QoS must be supported by every ISP along a packet's route. Given the fragmented nature of the ISP market today, that won't be easy, he said. Kreins forecast a consolidation of large-scale ISPs - those that provide the core network backbones - but continued growth in the number of local and regional ISPs, who add value to wholesale IP service with customer support and application. Kreins said Layer 3 switches will not play much of a role on the new Internet. "Layer 3 is meant for the boundary of the network, it's not a core facility,'' he said. "Gigabit products are much more a local proposition.'' -------------------- FORE with high-performance latest Berkeley GBit products and also owning the best ATM switching (for those that want better QoS and willing to work with more sophisticated ATM technology) will be in a very good position for the local networks.
