Cisco Systems Inc. this week unveiled several routing and optical networking enhancements designed to cost-effectively speed delivery of new services to enterprises.
At SuperComm 2001 here, Cisco rolled out 10G bit/sec OC-192 interfaces for its ONS 15454 SONET multiplexer for the metropolitan-area network. These new interfaces enable the ONS 15454 to scale from DS-1 to OC-192. The system also supports four-port Gigabit Ethernet and OC-12 interfaces.
With the OC-192 cards, service providers can support 16 OC-192s per rack - four per 1/4-rack 15454. This is in contrast to a single OC-192 per rack with "legacy" configurations, Cisco says. And current ONS 15454 customers can perform in-service upgrades of OC-48 cards to the new OC-192s, the company says.
Cisco also announced that the ONS 15454 now supports four fiber bidirectional line switched ring configurations, which provides a higher level of protection and restoration for increasing amounts of traffic at OC-192.
Analysts say it is about time for Cisco to address the bandwidth and restoration limitations of the ONS 15454. But the enhancements may be short-lived, as Cisco seems to be developing the next generation 15454 platform.
"Although it does provide the needed short-term 10G bit/sec support existing customers need, and enhances the SONET resiliency of Cisco's metro solution, this platform still has a forklift upgrade in its future before it can fully support 10G bit/sec," says market researcher Current Analysis Inc. in a recent report. "Lack of 10G bit/sec prior to the expected release of the new backplane for the 15454 next year was becoming a potential timing thorn in Cisco's side, and it was important for the company to address this while working hard on the next chassis and feature set."
Cisco also unveiled at SuperComm channelized OC-12 and OC-48 modules for its 7600 OSR router. These interfaces are intended to enable high-density aggregation of WAN links. The four- and eight-port OC-12, and one- and two-port OC-48 channelized interface modules enable the 7600 to support 2,200 DS-3s and 700 OC-3s in a 7-foot rack.
The company also announced the 12406 Internet Router, a 1/4-rack, 10G-bit/sec device designed to provide high-bandwidth routing in a small form factor for space-constrained service providers. The 12406 features six slots for 12000 series line cards, and a 120G bit/sec of throughput.
Lastly, Cisco introduced a management appliance that automates the configuration of Cisco devices in a network. The Intelligence Engine 2100 is one rack unit high and a single one supports 500 Cisco devices, from the 800 series routers to the 12000 series routers.
The IE 2100 uses publish and subscribe technology and an XML API to update configurations on IOS 12.X-based devices.
