Abstract

The IETF's Open Pluggable Edge Services (OPES) working group focuses on rule-based, in-line transformation services of data flows between 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.
