Cisco Announces Advanced Router System for Cisco 7500 Series Routers; Next-Generation Routing Technology Increases Switching Capabilities and Accelerates Services.
This system increases the performance and switching capabilities of the Cisco 7500, while enabling Internet service providers and enterprise customers to accelerate advanced network services such as security, quality of service (QoS) and detailed accounting.
"Service providers need advanced routers to enable them to scale Layer 3 switching performance and advanced IP services to meet the increasing demands of the Internet," said Richard Palmer, director of marketing for Cisco Systems' Internet Service Provider Business Unit.
"Enterprise networks also require scalability to support a mix of applications with different bandwidth and latency requirements such as multimedia and mission-critical applications. To meet these requirements, an advanced router must have a distributed switching architecture, deliver highly scalable control and forwarding and accelerate IP services.
"The advanced router system for the Cisco 7500 series achieves these goals with a set of hardware products and Cisco IOS(TM) software enhancements."
Conventional routers use a centralized processor to perform all Layer 3 switching, apply advanced services and manage route updates. This process can significantly limit overall router performance. To achieve the performance necessary for today's Internet and intranets, advanced routers such as the Cisco 7500 series and the Cisco 12000 series Gigabit Switch Router (GSR) use a distributed system architecture.
The Cisco 7500 implements a distributed architecture through the use of versatile interface processors (VIPs) that enable significantly higher throughput and switching performance by spreading the switching activity to multiple processors.
"Upgrading to VIP technology boosted the performance of our 7500 router backbone tremendously," said Ed Kern, vice president of engineering at Digex Corporation. "Having VIP technology coupled with Route/Switch Processor 4s (RSP4s) has given us the performance necessary for a next-generation class of service. It has also created packet switching rates that will take us all the way to the next platform, the Cisco 12000 Gigabit Switch Router."
As part of the advanced router system, Cisco is announcing a second generation VIP, model 50 (VIP2-50), which increases the switching capacity of the Cisco 7500 by more than 500 percent over basic Cisco 7500 systems without the benefit of VIP technology. The increased switching capacity in a single router improves router throughput and reduces the number of routers necessary to manage a given load, thereby saving equipment costs.
Cisco's advanced router system also protects initial investments in Cisco 7500 routers by scaling performance without costly chassis upgrades for the latest network interfaces such as Fast Ethernet, Asynchronous Transfer Mode (ATM), high-speed serial interface (HSSI), Packet over SONET Interface Processors (POSIPs), channelized T3/E3 and packet over T3/E3.
Conventional router performance also suffers in complex network environments that experience multiple route topology changes. The distributed architecture of the Cisco 7500 allows for scalable control and forwarding functions, minimizing the impact of constant route updates.
The Cisco 7500 does this by separating data functions such as packet routing, switching and QoS provisioning from control functions like route processing, allowing the overall system performance to scale. Advanced router system features such as Cisco Express Forwarding (CEF), Tag Switching and RSP4 streamline switching decisions and manage complex network topology changes to ensure packet throughput in highly dynamic environments.
With the integration of the VIP2-50, RSP4, CEF and Tag Switching advanced router system features, the Cisco 7500 delivers the products and software for the most scalable, distributed router platform available today.
Other advanced router system extensions for the Cisco 7500, such as Distributed Weighted Fair Queuing and Distributed Random Early Detection, allow these queuing systems to scale to support OC-3 line rates. This feature represents an increase of ten times over previous methods.
Future advanced router system extensions for the Cisco 7500 will accelerate the performance of IP services and bring high-performance Gigabit Ethernet and OC-12 interfaces to the Cisco 7500.
Pricing and Availability
The VIP2-50, the latest member of the Cisco 7500 advanced router system, is available today on all Cisco 7500 series routers for $15,000.
