Abstract

This white paper explores enhancements to existing metro architectures that can serve as a catalyst for a broader modernization and optimization of incumbent carriers' service infrastructures. Included in this white paper are strategies for the optimal use of existing capital resources, and pragmatic migration steps to ease and facilitate network evolution. With the gradual adoption of new and more intelligent networking technologies, incumbent carriers can accelerate migration toward the more dynamic and data-centric service architectures that will fuel future network growth and increase competitive differentiation. These service architectures must support the cost-effective deployment of new service offerings such as gigabit Ethernet over SDH. Key technology enablers for these agile network architectures, including optical routing and signaling, virtual concatenation (VC: G.707), link capacity adjustment scheme (LCAS: G.7042) and generic framing procedure (GFP: G.7041), are also discussed.

演进的城域传输和交换基础设施:通往运营商网络的高效以太网服务之路

本白皮书探讨了对现有城域架构的增强，这些增强可以作为催化剂，促进现有运营商服务基础设施的更广泛现代化和优化。本白皮书包含了优化现有资本资源的策略，以及简化和促进网络演进的实用迁移步骤。随着新的和更智能的网络技术的逐步采用，现有运营商可以加速向更动态和以数据为中心的服务架构的迁移，这将推动未来的网络增长并增加竞争差异化。这些服务体系结构必须支持新服务产品的经济高效部署，例如通过SDH的千兆以太网。本文还讨论了实现这些敏捷网络架构的关键技术，包括光路由和信令、虚拟连接(VC: G.707)、链路容量调整方案(LCAS: G.7042)和通用分帧过程(GFP: G.7041)。
