Usage
Information
The Single Window Protocol (SWP) provides flow control-based reliable communication between the
sending and receiving software tasks.
Important Points to Remember
• A sending task enqueues messages into the SWP queue3 for a receiving task and waits for an
acknowledgement.
• If no response is received within a defined period of time, the SWP timeout mechanism resubmits
the message at the head of the FIFO queue.
• After retrying a defined number of times, the following timeout message is generated:
SWP-2-NOMORETIMEOUT
• In the display output in Figure 5-46, a retry (Retries) value of zero indicates that the SWP
mechanism reached the maximum number of retransmissions without an acknowledgement.
