Extension headers on an IP Packet header carry optional Internet Layer information. In Bayware, the extension headers carry the microcode that implements the Network microservices according to the contract.
Flow Identifier is embedded in a fixed part of IPv6 header. Flow Profile and Flow Logic are placed in Bayware-specific IPv6 extension header.
Flow Profile defines flow policy: ingress packet processing policy, instruction execution policy, egress packet processing policy.
Flow Logic is a combination of path description, delivery instructions and program variables.
