Abstract

Techniques for encoding metadata representing a policy into a QUIC connection ID are described herein. A metadata-aware network including one or more enforcement nodes, a policy engine, and/or a connection datastore may be utilized to enforce a policy and route communications on a QUIC connection. The policy engine may be configured to encode metadata representing one or more network policies into a QUIC source connection ID (SCID) and/or may store a mapping between the SCID and a corresponding destination connection ID (DCID) in the connection datastore. The policy engine may communicate with a QUIC application server and/or one or more QUIC proxy nodes to encode the SCID into a QUIC packet. The enforcement nodes may access the metadata and enforce the policies via a connection ID included in a QUIC header of a QUIC packet or by performing a lookup in the connection datastore using the connection ID.
