Method and system for controlling network device and recording medium storing program for executing the method

A method for providing a service in a network by a second device, the method comprising:

• receiving a notification about generating a task including a plurality of subtasks identified based on an order of actions necessary for performing the service from a first device;
• requesting a task when a first subtask included in the task is to be performed to the second device;
• receiving the task from the first device;
• performing the first subtask included in the received task;
• transmittin a notification about an updated task to at least one device connected to the network according to the performing of the first subtask;
• and
• transferring the updated task to a third device in response to a request of the third device which can perform second subtask included in the updated subtask,
• wherein the first subtask and the second subtask are identified based on order to be performed.

A task generating device for performing a task comprising:

• a user interface (UI) which interfaces a user and the task generating device;
• a storage unit which stores information on a task;
• a data transmitter and receiver which transmits and receives data via the network;
• and
• a controlling unit which, generates the task including a plurality of subtasks identified based on an order of actions necessary for performing a service, determines whether at least one subtask is to be performed by the task generatin device, notifies the generation of the task to at least one task performing device connected to the network based on the determination and transfers the task to the task performing device in response to request of a second device.

A task performing device for providing a service in a network, comprising:

• a data transmitter and receiver which transmits and receives data via the network;
• and
• a controlling unit which, if the controlling unit receives a notice of generating a task including a plurality of subtasks identified based on an order of actions necessary for performing the service, from a task generating device, requests a task when a first subtask included in the task is to be performed to the task generating device, receives the task from the task generating device, performs the first subtask included in the received task and transmits a notification about an updated task to at least one task performing device connected to the network according to the performing of the first subtask and transfers the updated task to another task performing device in response to request of the other task performing device which can perform second subtask included in the updated subtask,
• wherein the first subtask and the second subtask are identified based on the order to be performed.

A non-transitory computer readable recording medium having embodied thereon a computer program for executing a method for providing a service in a network by a first device, the method comprising:

• generating a task including a plurality of subtasks identified based on an order of actions necessary for performing the service;
• determining whether at least one subtask is to be performed by the first device;
• notifying the generation of the task to at least one device connected to the network based on the determination;
• and
• transferring the task to second device in response to request of the second device.

A non-transitory computer readable recording medium having embodied thereon a computer program for executing a method for providing a service in a network by a first device, the recording medium comprising:

• receiving a notification about generating a task including a plurality of subtasks identified based on an order of actions necessary for performing the service from afirst device;
• requesting a task, when a first subtask included in the task is to be performed, to the first device;
• receiving the task from the first device;
• performing the first subtask included in the received task;
• transmitting a notification about updated task to at least one device connected to the network according to the performing of the first subtask and
• transferring the updated task to third device in response to request of the third device which can perform second subtask included in the updated subtask,
• wherein the first subtask and the second subtask is identified based on the order to be performed.
