Retry technique for multi-tier network communication systems

A computer-implemented method for managing network communications, the method comprising:

• designating a retry point on a first communication path between a sender and an intended recipient, the first communication path comprising a plurality of logical components that sequentially receive and forward a communication from the sender to the intended recipient, the retry point forming a portion of the communication path;
• if the sender communication fails to access the intended recipient along a portion of the communication path beyond the retry point, then signaling the retry point an indication that the sender communication failed to access the intended recipient;
• then
• resending the sender communication to access the intended recipient only from the retry point.

A computer-implemented method for processing network communications, the method comprising:

• designating a retry point on a first communication path between a sender and an intended recipient, the first communication path comprising a plurality of logical components that sequentially receive and forward a communication from the sender to the intended recipient, the retry point forming a portion of the communication path;
• if the sender communication fails to access the intended recipient along a portion of the communication path between the retry point and the intended recipient, then signaling the retry point an indication that the sender communication failed to access the intended recipient;
• determining whether the sender communication is retriable;
• and
• if the sender request is retriable, resending the sender communication to access the intended recipient from the retry point.

A computer readable medium carrying one or more sequences of instructions for managing network communications, wherein execution of the one or more sequences of instructions by one or more processors causes the one or more processors to perform the steps of:

• designating a retry point on a first communication path between a sender and an intended recipient, the first communication path comprising a plurality of logical components that sequentially receive and forward a communication from the sender to the intended recipient, the retry point forming a portion of the communication path;
• if the sender communication fails to access the intended recipient along a portion of the communication path beyond the retry point, then signaling the retry point an indication that the sender communication failed to access the intended recipient;
• and
• resending the sender communication to access the intended recipient from the retry point.
