7600-SIP-200产品简介
The Cisco® I-Flex design 7600-SIP-200思科原装线卡模块combines shared port adapters (SPAs) and SPA interface processors (SIPs), leveraging an extensible design that enables service prioritization for voice, video and data services. Enterpris7600-SIP-200思科原装线卡模块e and service provider customers can take advantage of improved slot economics resulting from modular port adapters that are interchangeable across Cisco routing platforms. The I-Flex design maximizes connectivity options and offers superior service intelligence through programmable interface processors that deliver line-rate performance. I-Flex enhances speed-to-service revenue and provides a rich set of quality-of-service (QoS) features for premium service delivery while effectively redu7600-SIP-200思科原装线卡模块cing the overall cost of ownership.

Product Overview
The Cisco 7600 SIP-200 helps enable high-performance, 7600-SIP-200思科原装线卡模块intelligent WAN services. Enterprises and service providers can take full advantage of the increased scalability, performance, and rich features offered by the Cisco 7600 SIP-200, along with the many options for WAN aggregation and connectivity offered in the Cisco SPA/SIP portfolio. The Cisco 7600 SIP-200 provides feature parity with the Enhanced FlexWAN while offering twice the performance and increased scalability.

Cisco 7600 Series Routers offer innovative, next-generation converged services for enterprises and service providers. Built on foundation technologies such as security, QoS, and high availability, the Cisco SPA/SIP portfolio helps enable the delivery of these value-added services for new revenue streams.
The Cisco 7600 SIP-200 is supported both on Cisco 7600 platform and Catalyst 6500 platform.
Applications 7600-SIP-200思科原装线卡模块

Ideal for enterprise headend and service provider edge aggregation, the Cisco 7600 SIP-200 supports up to 622 Mbps of bandwidth and numerous interfaces. (Note: Bandwidth is expected to decrease when QoS is enabled.) The innovative architecture of this industry-leading WAN services module delivers Cisco 7500 Series feature parity and feature velocity for time-to-market solutions.

Enterprise and Service Provider WAN Aggregation
The Cisco 7600 SIP-200 helps enterprises and service providers deploy high-density WAN aggregation, based on Frame Relay, Point-to-Point Protocol (PPP), High-Level Data Link Control (HDLC), ATM, or Packet over SONET/SDH (POS). Additionally, service providers can take advantage of the Multiprotocol Label Switching (MPLS) and Any Transport over MPLS (AtoM) options supported on the Cisco 7600 SIP-200 to offer Layer 2 and Layer 3 VPNs. Rich QoS features and distributed processing attributes of the Cisco 7600 SIP-200 make it a cornerstone of a highly scalable WAN aggregation solution. Higher-layer applications can easily be supported on this end-to-end network to allow intelligent data, voice, video, and security services - all on the same platform - to provide integrated, easy-to-use application delivery and control.

Service Convergence and Intelligent Network Services for Next-Generation Applications
The unique value the Cisco 7600 Series provides is the convergence supported from the physical layer to a highly scalable application layer. The Cisco 7600 SIP-200 simplifies network design and deployment by allowing consolidation of LAN, WAN, and metropolitan-area network (MAN) interfaces into a single, highly scalable platform. The Cisco 7600 SIP-200, by integrating WAN termination, rich QoS features, bandwidth optimization, and security on the same module, obviates the need for multiple service modules, offering tremendous cost savings. The rich classification features supported on the Cisco 7600 SIP-200 enable identification of packets from Layer 2 to Layer 7 of the OSI model, enabling application-level intelligence and security in the network.

Features and Benefits
The rich QoS features of the Cisco 7600 SIP-200 enable users to:
• Classify and mark packets for QoS treatment within the network
• Deliver bandwidth to business-critical applications
• Limit bandwidth to non-critical applications
• Avoid network congestion by dropping select low-priority packets
• Smooth out bursts and avoid packet discard in the network

In addition, low-speed WAN aggregation features supported include:
• Compressed Real-Time Protocol (cRTP) to maximize bandwidth utilization
• Distributed link fragmentation and interleaving (dLFI) to minimize jitter
• Multilink PPP (MLPPP), Multilink Frame Relay Protocol (MLFR), ATM VC Bundle, and Frame Relay VC Bundle to bundle multiple low-speed links
