Open Pluggable Edge Services: An Architecture for Networked Content Services

The IETF's open pluggable edge services (OPES) working group focuses on rule-based, in-line transformation services of data flows between two Internet endpoints, such as Web servers and Web clients. The group has developed an architectural framework to authorize, invoke, and trace such application-level services. The framework follows a one-party consent model, which requires that at least one of the application-layer endpoints explicitly authorize each service. OPES services must also be reversible by request of the application endpoints
