Abstract
Techniques to add environmental-impact and energy sustainability criteria and support to service function chains (SFCs). These techniques enabling steering of network traffic that carries energy sustainability related metadata within in an SFC based on energy sustainability or 'green criteria.' This allows for achieving, for example, so-called “green Operations, Administration and Maintenance (OAM)”, whether realized with Network Service Header (NSH), Segment Routing, Multi-protocol Label Switching (MPLS), etc. In other words, these techniques enhance service functions (SFs) and SFCs to allow for finding an energy sustainable or green path in an SFC, and to allow for conveying environmental information as in-line metadata.
