      • Magic

        public ByteString Magic()
        The first 4 bytes of a new connection must be these 0x64 0x75 0x75 0x64 (AKKA). The purpose of the "magic" is to detect and reject weird (accidental) accesses.

      • encodeConnectionHeader

        public ByteString encodeConnectionHeader​(int streamId)
        When establishing the connection this header is sent first. It contains a "magic" and the stream identifier for selecting control, ordinary, large inbound streams.

        The purpose of the "magic" is to detect and reject weird (accidental) accesses. The magic 4 bytes are 0x64 0x75 0x75 0x64 (AKKA).

        The streamId is encoded as 1 byte.

      • encodeFrameHeader

        public ByteString encodeFrameHeader​(int frameLength)
        Each frame starts with the frame header that contains the length of the frame. The frameLength is encoded as 4 bytes (little endian).
