System and method for improving content fetching by selecting tunnel devices

A method for fetching a content identified by a content identifier to a client device from a web server by using intermediate devices, for use with a first server that stores a list of the IP addresses of intermediate devices in a group that are each connected to the Internet using a wired network connection or a wireless network connection, wherein each of the intermediate devices in the group is associated with a first value of a first attribute type, the method comprising:

• receiving and storing, by the first server, for each of the intermediate devices in the group, the respective first value;
• adding, by the first server, in response to a communication initiating by an additional client device, the additional client device to the group by adding the IP address of the additional client device to the list;
• estimating or measuring, by the first server or by an intermediate device, the first value;
• storing, by the first server, the first value for associated with the additional client device;
• receiving, by the first server from the client device, a request that comprises the content identifier and a second value relating to the first attribute type;
• selecting, by the first server from the list, a first IP address associated with a first intermediate device which first value is equal to the second value;
• sending, by the first server to the selected first intermediate device, the content identifier using the IP address from the list of the selected first intermediate device;
• selecting, by the first server from the list, a second IP address associated with a second intermediate device that is different from the first intermediate device, wherein the first value of the second intermediate device is equal to the second value;
• sending, by the first server to the selected second intermediate device, the content identifier using the IP address from the list of the selected second intermediate device;
• receiving, by the first server from the selected first or the second intermediate device, the content;
• and
• sending, by the first server to the client device, the content,
• wherein the sending of the content identifier, by the first server to the selected first and second intermediate devices, is performed simultaneously,
• wherein the first attribute type corresponds to a bandwidth (BW) or Round-Trip delay Time (RTT) of a communication link, and
• wherein the first value is the respective estimation or measurement of the BW or RTT.
