摘要： Embodiments are provided herein to enable single level network abstraction for a service across one or more domains. The embodiments use a single network ID to identify a service and a corresponding virtual network topology across any number of domains at a physical network. A virtual network topology can be abstracted for each service, based on the physical underlying network topology. A network controller determines, for a service, the virtual network topology within a physical network, and binds the service to the virtual network topology via a virtual network ID, which defines a single forwarding domain of the virtual network topology across the physical network. The virtual network ID is then indicated to the nodes of the virtual network topology, thus enabling the nodes to identify and forward traffic for the service, within the single forwarding domain, between end clients from edge to edge of the physical network.

摘要： A network node used to construct a topology-transparent zone (TTZ). The network node may obtain a TTZ identifier (ID) that is uniquely associated with a TTZ. Additionally, the network node may obtain a first link that couples the network node to a second network node that is also assigned the TTZ ID and a second link that couples the network node to a third network node that is not assigned the TTZ ID. The network node may generate a router information (RI) link-state advertisement (LSA) that indicates whether the network node is a TTZ edge node or a TTZ internal node and that indicates the TTZ associated with the TTZ. The network node may distribute the RI LSA to the second network node that is also assigned the TTZ ID using the first link.
