This article describes an emerging service for next-generation networks, layer 1 virtual private networks. L1VPNs allow customers desiring to connect multiple sites to be supported over a single shared layer 1 network. In the article we first describe the transport network's evolution and the shift in expectations of both service providers and customers. We provide an overview of the motivation for L1VPNs and examples of network usage. We follow by reviewing existing GMPLS mechanisms (addressing, discovery, and signaling) for realizing L1VPN functionality and identifying other work areas.
