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 4-42, a retry (Retries) value of zero indicates that the
SWP mechanism reached the maximum number of retransmissions without an
acknowledgement.
