Interface NetworkExternalProcessorGrpc.AsyncService

All Known Implementing Classes:
NetworkExternalProcessorGrpc.NetworkExternalProcessorImplBase
Enclosing class:
NetworkExternalProcessorGrpc
public static interface NetworkExternalProcessorGrpc.AsyncService
 NetworkExternalProcessor service defines the contract between Envoy and
 external processing servers for L4 network traffic.

  • Method Details

    • process

      default io.grpc.stub.StreamObserver<ProcessingRequest> process(io.grpc.stub.StreamObserver<ProcessingResponse> responseObserver)
       Process establishes a bidirectional stream between Envoy and the external
 processing server. Envoy sends ProcessingRequests containing network data
 and the server responds with ProcessingResponses containing processing
 decisions and potentially modified data.
 The server should handle processing timeout properly to avoid blocking
 network traffic for extended periods. Any uncaught exceptions will
 be treated as errors and will terminate the stream.
 Implementation note: The server should process requests in the order
 they are received to maintain proper sequencing of network traffic.
