Random Request¶
Code for a randomized application
This module defines the RandomRequestApp, which will create random entanglement requests repeatedly. Useful for testing network properties and throughputs.
- class src.app.random_request.RandomRequestApp(node: QuantumRouter, others: List[str], seed: int, min_dur: int, max_dur: int, min_size: int, max_size: int, min_fidelity: float, max_fidelity: float)¶
Code for the random request application.
This application will create a request for entanglement with a random node (and with other random parameters). If the request is accepted, a new request will be made once it has expired. Otherwise, a new request will be made immediately. The responder and fidelity of failed request will be kept in the new request.
The RandomRequestApp class inherits three functions from the RequsetApp class: get_memory(memory_info), get_throughput(), get_other_reservation(reservation). The “get_memory” function consumes the memory when the qualified entanglement is generated. The “get_throughput” function provides the throughput of the serving reservation. The “get_other_reservation” function accepts reservation when node is the responder node.

- get_reserve_res(reservation: Reservation, result: bool) None¶
Method to receive reservation result from network manager.
- Parameters:
reservation (Reservation) – reservation that has been completed.
result (bool) – result of the request (approved/rejected).
- Side Effects:
May schedule a start/retry event based on reservation result.
- retry(responder: str, fidelity: float) None¶
Method to retry a failed request.
- Parameters:
responder (str) – responder node of failed request.
fidelity (float) – fidelity of failed request.
- Side Effects:
Will create request for network manager on node.
- start()¶
Method to start the application.
This method will:
Choose a random destination node from the others list.
Choose a start time between 1-2 seconds in the future.
Choose a random duration between min_dur and max_dur to set end_time
Pick a number of memories to request between min_size and max_size
Pick a random fidelity between min_fidelity and max_fidelity.
Use its parent class start function to create request
- Side Effects:
Will create request for network manager on node.
