		To avoid interacting with the switch using low-level P4 rules (via the SBI), we created modular network services, which allow users to easily provision L2, L3, ACL, and INT network functions.
		These services require users to define the service endpoints as well as some high-level service configuration, while leaving the rest of complexity to tailored service handlers that interact with the SBI on behalf of the user.
