Identifier based communication system and method for controlling data transport therein
First Claim
1. A method for controlling data transport in an ID based communication system, the method comprising:
- generating and transporting, by a data receiving apparatus, an information request message for requesting data information of contents corresponding to a content ID, the information request message further including a data receiving rate of the data receiving apparatus;
receiving, by the data receiving apparatus, a response message including the data information regarding the contents corresponding to the content ID from a plurality of data providing apparatuses providing the contents requested by the data receiving apparatus, a total data size of the contents and a unit transport size of the contents, and a data sending rate of the data providing apparatus;
determining, by the data receiving apparatus, the total number of the data corresponding to the contents based on the total data size of the contents and the unit transport size of the contents included in the response message;
deciding, by the data receiving apparatus, one or more requested data among the data corresponding to the contents based on the data sending rate of the data providing apparatus, the total data size of the contents, the unit transport size of the contents, the data receiving rate of the data receiving apparatus, and a buffer size and generating and transporting a data request message for requesting transportation of the requested data to the data providing apparatus; and
receiving, by the data receiving apparatus, a detected data from the data providing apparatus,wherein the data providing apparatus detects one or more requested data verified from the data request message among the data corresponding to the contents, andwherein the data sending rate is adjusted, by the data providing apparatus, based on the data receiving rate.

11. An ID based communication system comprising:
-
a plurality of data providing apparatuses managing data corresponding to one or more contents and information of the data and providing requested data and the information of the data; and a data receiving apparatus transporting an information request message for requesting data information of contents corresponding to a content ID, the information request message further including a data receiving rate of the data receiving apparatus, and verifying the data information regarding the contents from a response message received in response to the information request message to request decided requested data among data corresponding to the contents to any one data providing apparatus providing the contents requested by the data receiving apparatus, wherein the data receiving apparatus determines the total number of the data corresponding to the contents based on a total data size of the contents and a unit transport size of the contents included in the response message and decides some or all of the data corresponding to the contents as the requested data according to specifications such as a data sending rate of the data providing apparatus, the total data size of the contents, the unit transport size of the contents, the data receiving rate of the data receiving apparatus, and a buffer size, wherein the data receiving apparatus generates and transports a data request message for requesting transportation of the requested data to the data providing apparatus, and receives the requested data from the data providing apparatus, wherein the data providing apparatus adjusts the data sending rate based on the data receiving rate, and wherein the response message includes the adjusted data sending rate. - View Dependent Claims (12, 13, 14, 15)
