Abstract

A method of controlling data transfer, a method of controlling content transfer, a method of obtaining content processing information, and a system for transferring content are provided. The method of controlling data transfer in a data interoperable environment includes: receiving a request for transmitting data from a client; gathering information on entities which are to participate in transmitting data; forming a chain including at least two entities by using the gathered information on the entities; transmitting a plurality of data through the chain; and receiving an event message for representing a transmission status of the data transmitted from at least one of the entities included in the chain. Accordingly, it is possible to control a transmission of the data so that the plurality of data can be transmitted through a single session and to receive the transmission status of the data as an event message.

Claims

1. A computer-implemented method comprising:

receiving a message indicating that a controller has entered a failure state;

detecting that the controller has entered a failure state based on the received message; and

designating an entity as the controller based on detecting the failure state.

2. The method of claim 1, wherein the message further indicates that the entity is not the controller.

3. The method of claim 1, further comprising launching a controller electing procedure based on detecting that the controller has entered the failure state.

4. The method of claim 3, wherein launching the controller electing procedure further comprises:

sharing, among devices associated with a domain, data describing a capability of each device;

performing the controller electing procedure based on comparing, among the devices, the capability of each device with each other; and

designating the entity as the controller for the domain based on the performed controller electing procedure.

5. A device comprising:

an interface configured to receive a message indicating that a controller has entered a failure state; and

a processor configured to;

detect that the controller has entered a failure state based on the received message, and

designate an entity as the controller based on detecting the failure state.

6. The device of claim 5, wherein the message further indicates that the entity is not the controller.

7. The device of claim 5, wherein the processor is further configured to launch a controller electing procedure based on detecting that the controller has entered the failure state.

8. The device of claim 7, wherein launching the controller electing procedure further comprises:

sharing, among devices associated with a domain, data describing a capability of each device;

performing the controller electing procedure based on comparing, among the devices, the capability of each device with each other; and

designating the entity as the controller for the domain based on the performed controller electing procedure.

9. A system comprising:

one or more computers;

a computer-readable medium coupled to the one or more computers having instructions stored thereon which, when executed by the one or more computers, causes the one or more computers to perform operations comprising;

receiving a message indicating that a controller has entered a failure state,

detecting that the controller has entered a failure state based on the received message, and

designating an entity as the controller based on detecting the failure state.

10. The system of claim 9, wherein the message further indicates that the entity is not the controller.

11. The system of claim 9, wherein the operations further comprise launching a controller electing procedure based on detecting that the controller has entered the failure state.

12. The system of claim 11, wherein launching the controller electing procedure further comprises:

sharing, among devices associated with a domain, data describing a capability of each device;

performing the controller electing procedure based on comparing, among the devices, the capability of each device with each other; and

designating the entity as the controller for the domain based on the performed controller electing procedure.
