Michael, to my knowledge CSCO's ATM is directed to the enterprise customers not to carriers. ...CSCO's ATM..." series are targeted at enterprise customers, rather than service provider or carrier customers. techstocks.com CSCO pulled their big Carrier ATM that they got from Stratacom out last summer Message 9390045 Cisco has canceled development of an ATM switch called the TGX 8750, widely viewed as a crucial product for competing with Nortel and Ascend. So that CSCO's WAN strategy is now anyone's guess: Message 9370055 With the recent LU/WCOM " imbroglio ", also very properly labelled as " LU's Achilles Heel " in your previous post, < VBG>, it now appears that NN is the only telco OEM with a carrier class ATM, the Main Street Express36190 newbridge.com The MainStreetXpress 36190 Core Services Switch is the world's most powerful ATM switch, supporting many broadband applications on a single ATM core network. Are we going to hear soon that LU, " ditched their Ascend /Cascade Comm ATM switch, after the MCI/WCOM debacle? Stay tuned, :-)) TA

Sunday morning reading: cookreport.com ROSS CALLON, IRONBRIDGE Chief Architect, Looks at QoS, Standards and Engineering Issues of Next Generation Routers Terabit Whitepaper: ironbridgenetworks.com Selected quotes: "Because developers of terabit-capable routers have needed to deploy substantial technical resources to achieve high packet forwarding performance, many have left network management as a "to-do." After all, they argue, management doesn't become critical until the networks reach a large size. However, unless manageability is designed into a product before the first line of code is written, or the first ASIC gate is etched, the goals of performance and scalability will never be reached.. . . Few new technologies have experienced the kind of rapid market penetration seen by the Internet. But the Internet is not only expanding in size, it is also becoming much more complex. The Internet is giving birth to a vast array of services and applications, and as these emerge, grow, compete and (in some cases) die, the characteristics of the traffic mix will change. Flow rates, packet sizes, burstiness, mission-criticality and tolerance for latency and jitter, these and other characteristics will evolve in ways that are virtually impossible to predict. Not only must the Internet core grow with increasing traffic, it must be adaptable as traffic characteristics change. Network management must be designed to scale as the core network grows and to implement changes quickly and easily. . . Internet routing protocols can distribute traffic unevenly, causing congestion in some segments of the network while other segments go under-utilized. Routing and switching equipment requires different skill sets and operational procedures. . . Ten Key Terabit Router Management Questions. Implementation 1. Does management scale to support multiple terabit speed nodes? 2 Can the router manager be integrated with other management applications? Operation 3. Can faults be rapidly isolated, accurately diagnosed and speedily resolved? 4. Can service be monitored in terms of the Service Level Agreement (SLA) commitments made to customers? Administration 5. Can the network be engineered and capacity planned? 6. Is management access flexible, yet controllable and secure? Maintenance 7. Are software upgrades non-disruptive and absolutely reliable? Provisioning 8. Can customers be provisioned with the service levels they need? 9. Is provisioning non-disruptive and absolutely reliable? Staffing 10. Are the demands on technical staff minimized? . . . . Network management systems are complex and, unlike packet forwarding performance, cannot be compared using a single yard-stick. But the comparison is none the less critical. The ten questions posed in this paper form a good basis for evaluating router management. While they are not intended to be comprehensive, the answers will highlight those attributes that contribute most directly to service performance. And when evaluating routers, network operators should be wary of claims of future capabilities. Unless support for a promised capability is specifically designed into the architecture of the router, it is unlikely a promise can be delivered upon. The bottom line is that the winners in the race for the new Internet core will not necessarily be the service providers with the fastest routers. The winners will be those service providers that successfully provision and operate utility-class services; that meet the varying and demanding business needs of their customers; and manage and administer their services efficiently and effectively. Router management will make a key contribution to their success." techcapital.com "[Cisco and Juniper products are] a generation behind what we're doing," Lavia claims.
