1. A method for sending data over the Internet, said method comprising:
- receiving a plurality of requests for a particular resource provided at a remote server on the Internet, the plurality of requests being provided by different requestors;
retrieving the particular resource from the remote server once for the plurality of requests to obtain the particular resource requested by the plurality of requests; and
thereafter sending the particular resource to the different requestors,wherein said retrieving and/or said sending are performed after a predetermined quantity of the plurality of requests have been received,wherein the particular resource comprises digital data, andwherein said sending of the particular resource to the different requestors comprises forming multi-destination data packets to carry data of the particular resource, and transmitting the multi-destination data packets.

Abstract
Techniques for efficiently and economically providing data transfer through data networks are disclosed. The techniques are particularly suitable for Internet data transfers. In one aspect, delayed response processing is utilized. Requests for common content are initially queued. After a short period of time, the queued requests are processed as a group so as to better utilize available bandwidth, particularly in times where traffic or congestion is high. In another aspect, multiple-destination data packets are utilized.

3. A data transmission system for transmitting data from content servers to requestors through a data network, said data transmission system comprising:
-
a plurality of data distribution centers, said data distribution centers being connected to the data network, wherein data transmissions between the content servers and said data distribution centers use a multi-destination format so as to reduce congestion, and wherein the multi-destination format uses multi-destination data packets, the multi-destination data packets include at least multiple destination fields and a data field. - View Dependent Claims (4, 5, 6, 7)

8. A system for transmitting data through a data network from servers to clients, said system comprising:
-
a plurality of data distribution centers coupled to the data network; and server modules provided in the servers, said server modules operate to receive data to be transmitted to the clients and to form multi-destination packets to carry the data to at least one of said data distribution centers, wherein said data distribution centers receive the multi-destination packets from said server modules and operates to convert the multi-destination packets into single-destination packets and to delivery the single-destination packets to the appropriate clients. - View Dependent Claims (9, 10, 11)
