Systems and methods for zero touch configuration for a mesh of nodes using Segment Routing Flexible Algorithm define a Flex Algo Definition (FAD) of an auto-mesh plane. A method, in one embodiment, includes, responsive to the FAD, providing an advertisement of a Prefix Segment Identifier (SID) for a node in the auto-mesh plane; and including a flag in the advertisement designating whether the node is a destination node or a non-destination node in the auto-mesh plane. The destination node is one which requires transport connectivity to all other destination nodes in the auto-mesh plane, and the non-destination node is one used for reachability to all the destination nodes.

Systems and methods include maintaining a network plane in Segment Routing (SR) Flexible Algorithm having a Flexible Algorithm Definition (FAD) based on latency; receiving a request for a service over a SR network where the service is sensitive to a specific latency; and determining a label stack including one or more Segment Identifiers (SID) for the service, with the one or more SIDs based on the network plane in SR Flexible Algorithm. This can be used for Private Line Emulation (PLE) services and Circuit Emulation (CEM) services over SR, ensuring latency while not requiring large label stacks.

Systems and methods for extended protection in a Segment Routing network that utilizes Flexible Algorithm include defining a first Flexible Algorithm that segregates the Segment Routing network into a first subset network that excludes any of links and nodes from the Segment Routing network; defining a second Flexible Algorithm that segregates the Segment Routing network into a second subset network, different from the first subset network; and defining extended protection for the first Flexible Algorithm with the second Flexible Algorithm whereby the second Flexible Algorithm is usable for path to protect the first Flexible Algorithm.
