| Internet-Draft WebSocket mapping for SPs November 2014 |
| |
| |
| 1. Underlying protocol |
| |
| This mapping should be layered on the top of WebSocket protocol as |
| defined in RFC 6455. |
| |
| 2. Connection initiation |
| |
| Standard WebSocket handshake is done. Sec-WebSocket-Protocol field |
| MUST be set according to the following table: |
| |
| x-nanomsg-pair for NN_PAIR sockets |
| |
| x-nanomsg-req for NN_REQ sockets |
| |
| x-nanomsg-rep for NN_REP sockets |
| |
| x-nanomsg-pub for NN_PUB sockets |
| |
| x-nanomsg-sub for NN_SUB sockets |
| |
| x-nanomsg-surveyor for NN_SURVEYOR sockets |
| |
| x-nanomsg-respondent for NN_RESPONDENT sockets |
| |
| x-nanomsg-push for NN_PUSH sockets |
| |
| x-nanomsg-pull for NN_PULL sockets |
| |
| x-nanomsg-bus for NN_BUS sockets |
| |
| 3. Message |
| |
| SP message maps directly to WebSocket message. The message can be |
| fragmented as needed. Frame boundaries are ignored by the SP layer. |
| |
| 4. IANA Considerations |
| |
| This memo includes no request to IANA. |
| |
| 5. Security Considerations |
| |
| The mapping isn't intended to provide any additional security in |
| addition to what WebSocket does. DoS concerns are addressed within |
| the specification. |
