Abstract:

The booming carrier ethernet technologies make up for the weaknesses of the traditional ethernet, and afford L2 VPN service with higher security and QoS. It describes three kinds of network infrastructure for L2 VPN based on carrier ethernet and traditional data network, and their respective application spots and suitable historical periods as well. The resulting considerations on maintenance and operation of the L2 VPN network and service also have been taken in this paper.

Key words: carrier ethernet, provider backbone bridging, virtual private LAN service, traditional data network, ATM
