System and method for virtual network topologies and VPN in multi-layer networks

摘要

Systems and methods for a multi-layer network to achieve network resource isolation among clients using the same server network, such as a VPN in a multi-layered network and interaction within the node, may include interaction between a server layer (e.g. L0 Photonic network) and the client layer (e.g. L1 network) that help the client layer (L1) gather information about the server-layer (L0) connection affinities. For example, the use of server layer (L0) connection affinities to construct Virtual Network Topologies (VNT) and/or network abstractions for customer traffic isolations in client layer (L1), the use of VNT to offer physical and/or logical network resource isolation for L1 customers, and provide L1 VPN services in a multi-layer environment.
