TCP Failure vs Transport Failure vs Application Failure

I understand that TCP Failure correspond to the layer of 'Transport' in TCP/IP stack.

Then which kind of failure is correspond to layer of 'Application' in TCP/IP stack? Application Failure or Transport Failure?

Or I am somehow wrong about all these mentioned above? Appreciate if anyone can share some insight. Many thanks.

Hi there,

Application failures relates to problems occurring in the application layer.

Transport failures relates to problem occurring in the transport layer.

I hope this helps,

Kind Regards,

David

How about TCP Failure?

Hi Wai,

TCP Failures are related to problems also occuring in the Transport Layer.

I will add, TCP failures take precedence over both Application and Transport failures. If a TCP error occurs, it will take precedence over any Application and Transport failures that are also occurring.

Kind Regards,

David

In DCRUM's term, the type of errors that you may find under each category:

TCP failures: Server connection refused, connection establishment timeout, client/server not responding errors.

Transport failures: All HTTP 4xx/5xx response codes, SSL failures, incomplete responses

Application failures: Operation attributes configured as failures. In other words, customized failures.
