目前，LAN技术主要是基于以太网的，并提供分组优化的交换技术。由于超过90%的互联网流量来自基于以太网的局域网，人们正在努力将以太网从局域网扩展到城域网，并进一步扩展到广域网。然而，本地以太网协议需要扩展或支持其他技术，以便在可扩展性，QoS，弹性，OAM等方面作为MAN技术取得成功。在MAN上承载以太网流量的两个新兴趋势可以分为本地以太网（IEEE）协议扩展和另一种传输技术（如MPLS网络）的封装。其目标是提供新的和具有挑战性的服务，如虚拟专用局域网服务，也称为透明局域网服务（TLS）。本文全面概述了以太网所需的扩展/支持，重点介绍了新兴的提供商桥接技术。
Currently, LAN technology is predominantly Ethernet-based and offers packet-optimized switched technology. With more than 90 percent of Internet traffic originating from Ethernet-based LANs, efforts are underway to extend Ethernet beyond LANs into MANs and further into WANs. However, native Ethernet protocols need extensions or support from other technologies in order to succeed as MAN technology in terms of scalability, QoS, resiliency, OAM, and so on. The two emerging trends to carry Ethernet traffic across the MAN can be classified into native Ethernet (IEEE) protocol extensions, and encapsulation by another transportation technology such as MPLS networks. The goal is to offer new and challenging services such as virtual private LAN service, also known as transparent LAN service (TLS). This article presents a comprehensive overview of the required extensions/support of the Ethernet with an emphasis on the emerging provider bridge technology.
