Abstract

The present invention relates to a method for changing service quality of a content adaptively. When service quality updating action for a connection is received the present method invokes an action, used for requesting allowance of a new access to a network, to a device conducting traffic transfer services in order that service quality of the connection may be changed. The invoked action carries input arguments including traffic descriptor of the connection, carried by the service quality updating action, which a traffic handle for identifying the traffic descriptor uniquely has been allocated in.

Claims

1. A method for establishing a new traffic stream when a resource required for the new traffic stream is insufficient, the method performed by a manager and comprising:

performing a setting operation for setting a first traffic stream in a device used for transmitting data, wherein the manager manages a traffic stream of the device and the setting operation comprises;

receiving, from a controller that controls the manager, a first connection request for requesting the first traffic stream, the first connection request comprising a description field for describing the first traffic stream;

generating a traffic stream identifier for identifying a traffic stream among a plurality of traffic streams transmitted by the device;

inserting the generated traffic stream identifier into the description field of the first connection request;

transmitting, to the device, a first traffic stream request comprising the description field with the traffic stream identifier inserted in order to set the first traffic stream in the device;

registering the generated traffic stream identifier in the device when the first traffic stream is successfully set;

receiving a second connection request from the controller for requesting the second traffic stream;

transmitting, to the device, a second traffic stream request in order to set a second traffic stream in the device when the second connection request is received;

receiving, from the device, a fail response indicating that the device has determined that an available resource is insufficient for both the traffic stream and the second traffic stream;

obtaining first priority information of the first traffic stream and second priority information of the second traffic stream after receiving the fail response;

comparing the first priority information to the second priority information;

transmitting a releasing request to the device if the first priority information indicates that the first traffic stream has a lower priority than a priority of the second traffic stream, the releasing request including the traffic stream identifier to identify the first traffic stream;

releasing, by the device, the first traffic stream identified by the traffic stream identifier included in the releasing request in order to recover a resource used for the first traffic stream;

setting the second traffic stream in the device when a resource required for the second traffic stream is recovered by releasing the first traffic stream;

registering a traffic stream identifier in the device for identifying the second traffic stream when the second traffic stream is set in the device; and

wherein each of the first and second priority information comprises at least a traffic importance number and a user importance number.

2. A managing device for establishing a new traffic stream, the managing device comprising:

an physical interface unit configured to transmit and receive data; and

a processor configured to perform a setting operation for setting a first traffic stream in a device used for transmitting data, wherein the setting operation comprises;

receiving, from a controller, a first connection request for requesting the first traffic stream, the first connection request comprising a description field for describing the first traffic stream;

generating a traffic stream identifier for identifying a traffic stream among a plurality of traffic streams transmitted by the device;

inserting the generated traffic stream identifier into the description field of the first connection request;

transmitting, to the device via the physical interface unit, a first traffic stream request comprising the description field with the traffic stream identifier inserted in order to set the first traffic stream in the device;

registering the generated traffic stream identifier in the device when the first traffic stream is successfully set;

receiving a second connection request from the controller for requesting the second traffic stream;

transmitting, to the device via the physical interface unit, a second traffic stream request in order to set a second traffic stream in the device when the second connection request is received;

receiving, from the device via the physical interface unit, a fail response indicating that the device has determined that an available resource is insufficient for both the traffic stream and the second traffic stream;

obtaining first priority information of the first traffic stream and second priority information of the second traffic stream after receiving the fail response;

comparing the first priority information to the second priority information;

transmitting a releasing request to the device via the physical interface unit if the first priority information indicates that the first traffic stream has a lower priority than a priority of the second traffic stream, the releasing request including the traffic stream identifier to identify the first traffic stream;

releasing, by the device, the first traffic stream identified by the traffic stream identifier included in the releasing request in order to recover a resource used for the first traffic stream;

registering a traffic stream identifier in the device for identifying the second traffic stream when the second traffic stream is set in the device;

setting the second traffic stream in the device when a resource required for the second traffic stream is recovered by releasing the first traffic stream; and

wherein each of the first and second priority information comprises at least a traffic importance number and a user importance number.
