AI Technical Summary
Current network deployments require service functions to handle additional packet level encapsulations for service function chain information, which can be challenging due to the lack of capability to manage these encapsulations.
A method that maps a tunnel identifier of an encapsulated data packet to an attachment circuit of a service function and rewrites the destination media access control (MAC) address of the data packet to the MAC address of the service function, allowing service functions to remain oblivious to underlying chain implementations.
Enables efficient implementation of service function chains without the need for service functions to handle metadata encapsulations, enhancing flexibility and reducing complexity in network deployments.
