1. A computer implemented method for ensuring a minimum quality of service between two network nodes, the method comprising:
receiving, from a first node of a customer network to an ingress node of a service provider network, packets bound for a second node on the customer network that is remote from the first node, wherein the packets include an identifier associated with a traffic type of a plurality of traffic types configured on the customer network;
mapping the packets to a set of segment routing identifiers corresponding to a network path according to the traffic type, the mapping based on the identifier associated with the packets that identifies the traffic type of the packets, wherein the network path is a virtual network within a shared physical network infrastructure of the service provider network and defines a path to the second node through devices in the service provider network that are consistent with one or more quality-of-service (QoS) parameters associated with the identifier corresponding to the traffic type; and
sending the packets via the network path to an egress node with connectivity to the second node according to a quality of service associated with the traffic type identified by the identifier.
