APPA 71 Problems and Solutions
some common issues and solutions for APPA 71, as reported by experts:
- Issue: The APPA 71 standard does not specify a default value for the
max-hopsparameter. This can lead to problems if the value is not set correctly, such as when the network topology changes or when the number of hops required to reach a destination increases. - Solution: The
max-hopsparameter should be set to a value that is appropriate for the network topology and the expected number of hops required to reach a destination. This value can be determined by consulting with network engineers or by monitoring the network traffic to see how many hops are typically required to reach destinations. - Issue: The APPA 71 standard does not specify a default value for the
timeoutparameter. This can lead to problems if the value is not set correctly, such as when the network is congested or when there is a problem with a network link. - Solution: The
timeoutparameter should be set to a value that is appropriate for the network conditions. This value can be determined by consulting with network engineers or by monitoring the network traffic to see how long it typically takes for messages to be delivered. - Issue: The APPA 71 standard does not specify a default value for the
retryparameter. This can lead to problems if the value is not set correctly, such as when messages are lost or when there is a problem with a network link. - Solution: The
retryparameter should be set to a value that is appropriate for the network conditions. This value can be determined by consulting with network engineers or by monitoring the network traffic to see how many times messages are typically retried before they are given up as lost.
These are just a few of the common issues and solutions for APPA 71. For more information, please consult the APPA 71 standard or contact an expert in APPA 71 implementation.
