Service orchestration in a communication infrastructure with different network domains

A system comprising:

• a hardware processor;
• and
• a non-transitory storage medium storing program instructions executable on the hardware processor to:
• receive a request to implement a service in a communication network;
• in response to the request, create virtualized environments in compute nodes in respective network domains of multiple different types of network domains comprising a first network domain and a second network domain;
• deploy network functions in the virtualized environments;
• establish a connection between the network functions to provide the service as part of service orchestration in the communication network, the service comprising respective tasks of the network functions;
• and
• communicate data between the network functions comprising translating, at edge devices of the respective network domains, domain-specific data packets according to protocols used in the multiple different types of network domains to domain-agnostic data packets comprising labels to support label-based forwarding of data packets between the network functions in the virtualized environments, the translating comprising:
• producing a first domain-agnostic data packet by encapsulating, at a first edge device, a first domain-specific data packet received from the first network domain with a header containing a label for label-based forwarding of the first domain-agnostic data packet through an interconnect, and
• producing a second domain-agnostic data packet by removing, at a second edge device, a tunneling protocol header from a second domain-specific data packet received from the second network domain, and replacing the tunneling protocol header with a header comprising a label for label-based forwarding of the second domain-agnostic data packet.

A method of a system comprising a hardware processor, comprising:

• receiving a request to implement a service in a communication network;
• based on the request, creating virtualized environments in compute nodes in respective network domains of multiple different types of network domains comprising a first network domain and a second network domain;
• deploying network functions in the virtualized environments;
• establishing a connection between the network functions to provide the service as part of service orchestration in the communication network, the service comprising respective tasks of the network functions;
• providing converters in edge devices associated with the respective network domains;
• and
• translating, at the edge devices, domain-specific data packets according to protocols used in the multiple different types of network domains to domain-agnostic data packets comprising labels to support label-based forwarding of data packets between the network functions in the virtualized environments, the translating comprising:
• producing a first domain-agnostic data packet by encapsulating, at a first edge device, a first domain-specific data packet received from the first network domain of with a header containing a label for label-based forwarding of the first domain-agnostic data packet through an interconnect, and
• producing a second domain-agnostic data packet by removing, at a second edge device, a tunneling protocol header from a second domain-specific data packet received from the second network domain, and replacing the tunneling protocol header with a header comprising a label for label-based forwarding of the second domain-agnostic data packet.
