        智能 IP 核心網絡

        簡化核心網絡
        如今,消費者對電信運營商有了更高的期許。除了傳統的連接服務外,他們還要求提供視頻、語音、VPN 以及 IP 富媒體內容。要在滿足這些要求的同時控制成本并優化效率,就需要將核心網絡基礎設施融合到 Cisco IP Next-Generation Network (IP NGN) 中。

        Cisco IP NGN 能夠:

        • 簡化核心網絡的架構

        • 降低成本和運營費用

        • 幫助您更為高效地提供當前的服務

        • 為成長迅猛的帶寬密集型寬帶服務提供可擴展性和容量

        采用 Cisco IP NGN 框架并結合智能化且兼具擴展性的 Cisco IP/MPLS 核心路由解決方案,可實現下一代服務的全部優點。

        針對核心網絡的 Carrier Routing System
        Cisco CRS-1 Carrier Routing System 具有每秒高達 92 兆兆位的交換能力,可為融合的分組基礎設施提供核心 IP/MPLS 路由功能。Cisco CRS-1 針對核心網絡采用了業界第一個完全分布式操作系統 Cisco IOS XR,幫助核心網絡實現了:

        • 可擴展性

        • 系統持續運行能力

        • 服務靈活性

        您可以“疊加”核心網絡并使用對等的匯聚路由層來構建一個單一系統,滿足新服務產生的巨大流量需求并整合 POP 架構。


        核心網絡中基于密集波分復用的 IP
        Cisco CRS-1 Carrier Routing System 融合了 IP 智能與密集波分復用 (IPoDWDM) 傳輸技術。它采用業界第一個兆兆位 IP 路由平臺,支持 ITU 可調波長,可降低核心網絡的成本。

        現在,Cisco CRS-1 還加入了 40 Gbps 接口,一舉超越 Cisco Raman Amplification Technology,將光波長延伸到了 2000 公里。通過在單個支持密集波分復用的 40 Gbps 波長中加入多個低速波長,可以大量減少再生站數量并優化光纖的使用。

        新興市場往往以大都市為中心并輻射到廣袤的地域,另外有些環境對可擴展性有著很高的要求同時又必須控制費用,Cisco IPoDWDM 以其在覆蓋范圍和可擴展性方面的特點成為這些新興市場和環境中核心網絡的理想之選。

        具有多機箱容量的核心網絡
        Cisco CRS-1 具有強大的擴展能力。在完全分布式 Cisco IOS XR 操作系統下,此多機箱解決方案能讓運營商在不中斷當前運營的情況下增加容量。

        在這個解決方案中,硬件和軟件所占用的資源各不相干,因此可以在核心網絡中使用單個多機箱系統集成轉發、控制及管理。它還為運營商提供了極佳的可靠性和靈活性,讓他們能輕松應對核心網絡的增長。

        提供靈活性和大容量
        Cisco CRS-1 Carrier Routing System 提供了服務靈活性、持續運行能力和大容量,并且傳輸速度最高可達每秒 92 兆兆位。

        提供高度安全、可擴展的服務
        Cisco XR 12000 系列路由器不但能夠實現高安全性的虛擬化、完整的服務交付和持續不中斷的系統運行,還具有多服務擴展能力。

        提高效率,降低費用
        Cisco ONS 15454 Multiservice Transport Platform 在全球各地廣泛采用,它能在提高網絡效率和加強投資保護的同時降低費用。
