Abstract: Techniques for a head-end node in one or more network autonomous systems to utilize a protocol to instantiate services on tail-end nodes. The head-end node can use a service request mechanism that is enabled by the protocol to request service instantiation on the tail-end node without a network operator having to manually configure the tail-end node, or even having access to the tail-end node. Additionally, the protocol may further provide mechanisms to define handling attributes for traffic of the service (e.g., Service-Level Agreement (SLA) parameters, an underlay transport protocol, etc.), service acknowledgement mechanisms for the head-end node to determine that the service was instantiated on the tail-end node, and so forth. In this way, a head-end node can be used to instantiate a service on a tail-end node without a network operator having to have direct access to the tail-end node to manually configure the tail-end node.
