Abstract

A network protocol is disclosed in which the network switch reports failure to transmit a message or packet to the source computer of a multiple computer system. The destination computer(s) is/are then instructed by the source computer to re-initialize the relevant memory locations. A transaction identifier (TID) is used to identify a source computer sending a stream of updating data for a specific memory location.

Claims

1. A method of a single source computer to correct for a data transmission error to another external computer wherein the single computer and the external computer have a shared memory location, said method of correction comprising:

(i) transmitting a data by a source computer to an external destination computer;

(ii) monitoring the data transmission to determine if the data transmission was unsuccessful so that the data was undelivered;

(iii) said source computer, on determining that the data transmission was unsuccessful, instructing said destination computer to overwrite a shared memory location to which the undelivered data relates by re-initializing said shared memory location to which the undelivered data relates; and

(iv) said source computer sending said external destination computer a current contents of said shared memory location to which the undelivered data related.

2. The method as in claim 1, wherein said data includes a count value indicative of the position of said data in a sequence of changed data, said method including the further step of:

(v) said source computer sending to said external destination computer an unincremented count value.

3. The method as in claim 1, wherein said data includes a count value indicative of the position of said data in a sequence of changed data, said method including the further step of:

(v) said source computer sending to said external destination computer an unincremented count value.

4. A computer program stored in a computer readable media, the computer program including executable computer program instructions and adapted for execution by a single computer to modify the operation of the single computer;

the modification of operation including performing a method of a single source computer to correct for a data transmission error to another external computer wherein the single computer and the external computer have a shared memory location comprising;

(i) transmitting a data by a source computer to an external destination computer;

(ii) monitoring the data transmission to determine if the data transmission was unsuccessful so that the data was undelivered;

(iii) said source computer, on determining that the data transmission was unsuccessful, instructing said destination computer to overwrite a shared memory location to which the undelivered data relates by re-initializing said shared memory location to which the undelivered data relates; and

(iv) said source computer sending said external destination computer a current contents of said shared memory location to which the undelivered data related.

5. A method of a single destination computer to correct for a data transmission error from an external source computer wherein the single destination computer and the external source computer have a shared memory location, said method of correction comprising:

receiving, by said destination computer, an indication that a data sent to said destination computer did not receive a data transmission and that the data in said transmission was undelivered;

receiving, by said destination computer, an instruction from said source computer to overwrite a shared memory location with said source computer to which the undelivered data relates;

said destination computer in response to said received instruction, re-initializing said shared memory location in said second computer to which the undelivered data relates;

receiving, by said destination computer, from said source computer a current contents of said shared memory location from said source computer to which the undelivered data related; and

storing, by said destination computer, the received contents into its shared memory location.

6. The method as in claim 5, wherein said data includes a count value indicative of the position of said data in a sequence of changed data, said method including the further step of:

(v) said destination computer receiving from said external source computer an unincremented count value.

7. The method as in claim 5, wherein said data includes a count value indicative of the position of said data in a sequence of changed data, said method including the further step of:

(v) said destination computer receiving from said external source computer an unincremented count value.

8. A computer program stored in a computer readable media, the computer program including executable computer program instructions and adapted for execution by a single computer to modify the operation of the single computer;

the modification of operation including performing a method of a single destination computer to correct for a data transmission error from an external source computer wherein the single destination computer and the external source computer have a shared memory location comprising;

receiving, by said destination computer, an indication that a data sent to said destination computer did not receive a data transmission and that the data in said transmission was undelivered;

receiving, by said destination computer, an instruction from said source computer to overwrite a shared memory location with said source computer to which the undelivered data relates;

said destination computer in response to said received instruction, re-initializing said shared memory location in said second computer to which the undelivered data relates;

receiving, by said destination computer, from said source computer a current contents of said shared memory location from said source computer to which the undelivered data related; and

storing, by said destination computer, the received contents into its shared memory location.
