Implementing IP Services at the Network Edge

A new type of internetworking device is changing the way Internet Service Providers (ISPs) and carriers deploy services. The Internet Protocol Services Switch (IPSS) platform offers improved service over traditional routers, and Implementing IP Services at the Network Edge is the timely, implementation-focused guide to helping ISPs and carriers get to this "edge" of networking capability and up to the forefront of today's competitive market.

The edge is the point where the network joins various access technologies such as DSL, cable, and wireless connections with the high-speed routed and optical core. It is at that strategic network position where a provider has subscriber identity and can apply value-added services before passing off all traffic to the core. The IPSS platform builds on the basic capabilities of the traditional router, but also offers, among many others, the following advantages:

• Residential broadband subscriber aggregation and management
• Adaptation of Frame Relay-based business into an IP backbone
• Sophisticated firewalling
• IPSec-based and MPLS-based VPNs
• Content management

Through implementation examples from actual provider networks, Implementing IP Services at the Network Edge shows readers how this technology can maximize new mass-market broadband deployments. The authors provide insight into provisioning capabilities, types of services, and various access technologies; and they also explain Internet architecture, regulations, types of ISPs and carriers and how they fit into the network, and market projections for subscriber services. Offering expanded services to customers garners increased revenue and lower subscriber turnover, and gives subscribers more affordable and sophisticated services.

Today's ISPs and carriers are faced with an increasingly competitive and commodity-driven market for which they must provide high-value IP services. This book is the practical and definitive tool for maintaining the "edge" in today's demanding internetworking environment.

一種新型的互聯網網絡設備正在改變互聯網服務提供商（ISP）和運營商部署服務的方式。互聯網協議服務交換機（IPSS）平台提供了比傳統路由器更好的服務，而《在網絡邊緣實施IP服務》是一本及時的、以實施為重點的指南，幫助ISP和運營商進入這種網絡能力的“邊緣”，並走在當今競爭激烈的市場前沿。

邊緣是網絡與DSL、有線和無線連接等各種接入技術以及高速路由和光纖核心相結合的地方。在這個戰略網絡位置上，提供商擁有訂閱者身份，可以在將所有流量傳送到核心之前應用增值服務。IPSS平台建立在傳統路由器的基本功能之上，還提供了以下優勢之一：

- 住宅寬帶訂閱者匯聚和管理
- 將基於幀中繼的業務轉換為IP骨幹網絡
- 複雜的防火牆
- 基於IPSec和MPLS的VPN
- 內容管理

通過實際提供商網絡的實施示例，《在網絡邊緣實施IP服務》向讀者展示了如何最大化新的大眾市場寬帶部署的技術。作者提供了有關供應能力、服務類型和各種接入技術的見解；他們還解釋了互聯網架構、法規、ISP和運營商的類型以及它們如何融入網絡，以及對訂閱者服務的市場預測。提供擴展服務給客戶可以獲得增加的收入和降低訂閱者流失率，並為訂閱者提供更實惠和複雜的服務。

當今的ISP和運營商面臨著競爭激烈且以商品為導向的市場，他們必須提供高價值的IP服務。這本書是在當今要求嚴格的互聯網網絡環境中保持“邊緣”的實用和明確的工具。
