Abstract: Techniques for devices in autonomous systems to utilize a protocol, such as a Border Gateway Protocol (BGP), to signal intent to instantiate services for establishing connections between the devices. For instance, first device(s) in a first autonomous system (AS) may determine to establish a connection with a second AS. The first device(s) may encode a service key into an Internet Protocol (IP) address where the service key indicates a service that is to be provisioned on second device(s) in the second AS. The first device(s) system may then advertise the IP address host-route using BGP, and the second device(s) may receive the BGP advertisement. The second device(s) may decode the service key from the IP address, and provision the service to establish the connection between the autonomous systems. Thus, the devices in may leverage existing protocols to signal intent to instantiate services and establish connections between autonomous systems.
