Some needed SPS extensions:

  • Reserve asset for exclusive control
  • Persistent connection to send low latency commands

Solution #1 Extension to existing Submit operation: Additional XML attribute to keep the connection alive so that server can accept real-time commands records in the incoming stream, optionally through websockets.

Solution #2 Implementation similar to SOS InsertResult: 1st register to get a "command stream ID", then send raw records with KVP request containing the ID, either via persistent HTTP connection or websockets.

Solution #3 Combined with asset locking: Call ReserveAsset request to reserve the asset for a given time period and obtain a "command stream ID" as above.
