From Wikipedia, the free encyclopedia

SWIFTNet InterAct Store and Forward is a protocol designed and supported by SWIFT. The protocol is used to exchange financial messages between organizations connected to services on to the SWIFTNet network [1].

[edit] Protocol

SWIFTNet InterAct Store and Forward is a Store and Forward protocol, implemented using a client-server protocol. SWIFT stores the message centrally, removing the need for the sender and receiver to be connected to the network simultaneously, unlike SWIFTNet InterAct Realtime.

[edit] Sending a message

The sender of the message is the client, and SWIFT is the server:

  1. client: sends a request to the receiver. The request contains the message payload to be sent.
  2. server: receives the request.
  3. server: Stores the message payload for later delivery to the receiver.
  4. server: sends the response - an acknowledgment that the message has been stored OK.
  5. client: receives the response.

[edit] Receiving a message

There are two delivery modes for receiving messages:

  • Pull mode - the receiver of the message is the client
  • Push mode - the receiver of the message is the server

[edit] Pull mode

In Pull mode, the receiver of the message is the client, and SWIFT is the server:

  1. client: sends a request to retrieve the message from SWIFT.
  2. server: receives the request.
  3. server: Retrieves the stored message payload and puts it in the response.
  4. server: sends the response.
  5. client: receives the response containing the message payload.
  6. client: processes the message payload.
  7. client: sends a request acknowledging receipt of the message to SWIFT.
  8. server: receives the request.
  9. server: processes the receipt and creates a response.
  10. server: sends the response.
  11. client: receives the response.

Pull mode takes two requests to receive one message. Pull mode is better suited to low-volume applications.

[edit] Push mode

In Push mode, the receiver of the message is the server, and SWIFT is the client:

  1. client: sends a request containing the stored message payload.
  2. server: receives the request.
  3. server: processes the message payload. Creates a response acknowledging receipt of the message.
  4. server: sends the response.
  5. client: receives the response.

Push mode takes one request to receive one message. Push mode is better suited to high-volume applications.

[edit] Application

SWIFTNet InterAct Store and Forward is best suited to applications where message delivery is not time-critical. For example:
