The Cisco® Interface Flexibility (I-Flex) design combines shared port adapters (SPAs) and SPA interface processors (SIPs), taking advantage of an extensible design that helps enable service prioritization for voice, video, and data services. Enterprise and service provider customers benefit from the improved economics of modular port adapters that are interchangeable across Cisco Systems® routing platforms.
Modular port adapters and programmable interface processors, which are interchangeable across Cisco routing platforms, protect network investments and reduce total cost of ownership (TCO). The Cisco I-Flex design maximizes connectivity options and offers superior service intelligence through programmable interface processors operating at line rate. This data sheet contains the specifications for the Cisco 7600 Series SPA Interface Processor-600 (7600 SIP 600; refer to Figure 1).
Ideal for both service provider and enterprise applications, the Cisco 7600 SIP 600) supports up to 10 Gbps of bandwidth and a wide range of interfaces; it provides the unique ability to combine both Layer 2 and Layer 3 services on the same line card. The combination of native Layer 2 bridging and Layer 3 routing distinguishes this line card among other products on the market, particularly in Metro Ethernet applications.
The innovative architecture of this industry-leading WAN services module is designed to deliver cost-effective high-touch features, combining both application-specific integrated circuit (ASIC) and network processor technology for an optimal combination of performance and flexibility. The Cisco 7600 SIP 600 provides distributed forwarding with proven ASIC technology in the forwarding path (routing and switching, NetFlow, access control lists [ACLs]) as well as for queuing and shaping functions to provide the maximum performance for these foundation features; additionally, a programmable network processor is included in the forwarding plane to facilitate flexibility and feature growth. This ideal technology combination provides customers with the necessary flexibility for future service deployments and allows them to scale the system capacity as required.
