Title: METHOD FOR OPTIMISING DOWNLOADING OF DATA
Abstract:
A method and apparatus in a first communication network node for enabling optimised downloading of HTTP transferred data to a client, where the first communication network node is associated to the client by a first TCP connection, and the first communication network node being further associated to a second communication network node by a second TCP connection. When downloading HTTP transferred data according to the method, the first communication network node receives from the client are quest, requesting for the HTTP transferred data from the second communication node, and initiates an interaction between the first communication network node and the client by sending to the client a first response in response to the request. Furthermore, the first communication network node forwards the request to the second communication network node, and forwards to the client a subsequent response, received from the second communication network node in response to the forwarded request, and forwards to the client the HTTP transferred data at an available bit-rate, after being received from the second communication network node. The first response is sent to the client before the subsequent response is forwarded to the client, and the available bit-rate for the requested HTTP transferred data is determined at least partly as a result of the interaction between the client and the first communication network node. By interacting with the client, and evaluating the first TCP connection during the preparation of the HTTP transferred data, a faster downloading to the client may be achieved.
