Abstract
A first device transmits messages to a second device. The first device keeps track of messages that have already been transmitted from the first device to the second device, experiences an interruption in transmission of messages at the first device, and resumes the transmission from the first device following the interruption. Resuming the transmission includes transmitting only messages that have not already been completely transmitted from the first device to the second device.
Claims20
A method, performed by a first device, to transmit data to a second device, the method comprising:
- beginning transmission of the data to the second device;
- storing indications of data that has been transmitted;
- experiencing an interruption in transmission of the data from the first device;
- and
- resuming transmission of the data to the second device after the interruption, wherein resuming transmission comprises identifying the data that has been transmitted based on the indications, and transmitting, to the second device, data that has not already been transmitted to the second device.
A computer program product tangibly embodied in an information carrier, the computer program product comprising instructions that cause a first device to:
- begin transmission of data to a second device;
- store indications of data that has been transmitted;
- and
- resume transmission of the data from the first device to the second device after an interruption in the transmission, wherein resuming transmission comprises identifying the data that has been transmitted based on the indications, and transmitting, to the second device, data that has not already been transmitted to the second device.
An apparatus comprising:
- a processor that executes instructions to:
- begin transmission of data to a second device;
- store indications of data that has been transmitted;
- and
- resume transmission of the data to the second device after an interruption in the transmission, wherein resuming transmission comprises identifying the data that has been transmitted based on the indications, and transmitting, to the second device, data that has not already been transmitted to the second device.
A system comprising:
- a repository for storing data objects;
- and
- a client, in communication with the repository, to load the data objects onto the repository, the data objects being transmitted from the client to the repository as messages, wherein a message comprises plural data objects;
- wherein, when loading the data objects, the client keeps track of messages that have already been transmitted to the repository, and resumes the transmission of the messages to the repository following an interruption in the transmission;
- wherein, when resuming the transmission, the client transmits only messages that have not already been completely transmitted to the repository;
- and
- wherein the client resumes the transmission either in response to a communication from the repository or automatically without requiring the communication from the repository.
