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:

transmitting a message to a controller;

detecting, based on failing to receive a response to the message from the controller within a predetermined amount of time, that the controller has entered a failure state; and

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

2. The method of claim 1, wherein designating an entity as the controller based on detecting the failure state includes launching a controller electing procedure based on detecting the failure state.

3. The method of claim 2, wherein launching a controller electing procedure based on detecting the failure state comprises:

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

performing an election competition 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 election competition.

4. A device comprising:

an interface configured to transmit a message to a controller; and

a processor configured to;

detect, based on failing to receive a response to the message from the controller within a predetermined amount of time, that the controller has entered a failure state, and

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

5. The device of claim 4, wherein designating an entity as the controller based on detecting the failure state includes launching a controller electing procedure based on detecting the failure state.

6. The device of claim 5, wherein launching a controller electing procedure based on detecting the failure state comprises:

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

performing an election competition 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 election competition.

7. 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;

transmitting a message to a controller,

detecting, based on failing to receive a response to the message from the controller within a predetermined amount of time, that the controller has entered a failure state, and

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

8. The system of claim 7, wherein designating an entity as the controller based on detecting the failure state includes launching a controller electing procedure based on detecting the failure state.

9. The system of claim 8, wherein launching a controller electing procedure based on detecting the failure state comprises:

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

performing an election competition 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 election competition.
