`elements including an acceleration server, clients, agents,
`Apr. 20, 2018, now Pat. No. 10,257,319, which is a
`— ° CP and peers, where communication requests generated by
`(Continued)
`applications are intercepted by the client on the same
`machine. The IP address of the server in the communication
`request
`is transmitted to the acceleration server, which
`provides a list of agents to use for this IP address. The
`communication request is sent to the agents. One or more of
`the agents respond with a list of peers that have previously
`seen someorall of the content which is the response to this
`request (after checking whether this data is still valid). The
`client then downloads the data from these peers in parts and
`in parallel, thereby speeding up the Web transfer, releasing
`congestion from the Web by fetching the information from
`multiple sources, and relieving traffic from Web servers by
`offloading the data transfers from them to nearby peers.

`which are hereby incorporated herein by reference in their
`entirety.
`
`FIELD OF THE INVENTION
`
`The present invention is related to Internet communica-
`tion, and moreparticularly, to improving data communica-
`tion speed and bandwidth efficiency on the Internet.
`
`BACKGROUND OF THE INVENTION
`
`There are several trends in network and Internet usage,
`which tremendously increase the bandwidth that is being
`used on the Internet. One such trend is that more and more
`video is being viewed on demand on the Internet. Such
`viewing includes the viewing of both large and short video
`clips. In addition, regular shows and full-featured films may
`be viewed on the Internet. Another trend that is increasing
`the traffic on the Internet is that Web sites (such as shopping
`portals, news portals, and social networks) are becoming
`global, meaning that the Web sites are serving people in
`many diverse places on the globe, and thus the data is
`traversing over longer stretches of the Internet, increasing
`the congestion.
`The increase in bandwidth consumption has created sev-
`eral major problems, a few of which are described below:
`The problem for users—the current Internet bandwidth is
`not sufficient, and thus the effective ‘speed’ experienced
`by users is slow;
`The problem for content owners—the tremendous amount of
`data being viewed by users is costing large amounts of
`money in hosting and bandwidth costs; and
`The problem for Internet Service Providers (ISPs)—the
`growth in Internettraffic is requiring the ISPs to increase
`the infrastructure costs (communication lines, routers,
`etc.) at tremendous financial expense.
`The need for a new methodofdata transfer that is fast for
`
`the consumer, cheap for the content distributor and does not
`require infrastructure investment for ISPs, has become a
`major issue which is yet unsolved.
`There have been many attempts at making the Internet
`faster for the consumer and cheaper for the broadcaster.
`Each such attempt is lacking in some aspect to become a
`widespread, practical solution, or is a partial solution in that
`it solves only a subset of the major problemsassociated with
`the increase in Internettraffic. Mostof the previous solutions
`require billions of dollars in capital investment for a com-
`

`prehensive solution. Many of these attempts are lacking in
`that muchofthe content on the Internet has become dynami-
`cally created per the user and the session of the user (this is
`what used to be called the “Web2.0” trend). This may be
`seen on the Amazon Website and the Salesforce Website,
`for example, where most of the page views on these Web
`sites is tailored to the viewer, and is thus different for any
`two viewers. This dynamic information makesit impossible
`for most of the solutions offered to date to store the content
`
`and provide it to others seeking similar content.
`Onesolution that has been in useis called a “proxy”. FIG.
`1 is a schematic diagram providing an example of use of a
`proxy within a network 2. A proxy, or proxy server 4, 6, 8
`is a device that is placed between one or more clients,
`illustrated in FIG. 1 as client devices 10, 12, 14, 16, 18, 20,
`that request data, via the Internet 22, and a Web server or
`Webservers 30, 32, 34 from which they are requesting the
`data. The proxyserver4, 6, 8 requests the data from the Web
`servers 30, 32, 34 on their behalf, and caches the responses
`from the Web servers 30, 32, 34, to provide to other client
`devices that make similar requests. If the proxy server 4, 6,
`8 is geographically close enoughtothe client devices 10, 12,
`14, 16, 18, 20, and if the storage and bandwidth of the proxy
`server 4, 6, 8 are large enough, the proxy server 4, 6, 8 will
`speed up the requests for the client devices 10, 12, 14, 16,
`18, 20 that it is serving.
`It should be noted, however, that to provide a compre-
`hensive solution for Internet surfing, the proxy servers of
`FIG. 1 would need to be deployed at every point around the
`world where the Internet is being consumed, andthe storage
`size of the proxy servers at each location would need to be
`near the sizeofall the data stored anywhere on the Internet.
`The abovementioned would lead to massive costs that are
`
`impractical. In addition, these proxy solutions cannot deal
`well with dynamic data that is prevalent now on the Web.
`There have been commercial companies, such as Akarnai,
`that have deployed such proxies locally around the world,
`and that are serving a select small group of sites on the
`Internet. If all sites on the Web were to be solved with such
`a solution, the capital investment would be in the range of
`billions of dollars. In addition, this type of solution does not
`handle dynamic content.
`To create large distribution systems without the large
`hardwarecosts involved with a proxy solution,“peer-to-peer
`file sharing” solutions have been introduced, such as, for
`example, BitTorrent. FIG. 2 is a schematic diagram provid-
`ing an example of a peer-to-peerfile transfer network 50. In
`the network 50, files are stored on computers of consumers,
`referred to herein as client devices 60. Each consumer can
`
`serve up data to other consumers, via the Internet 62, thus
`taking the load of serving off of the distributors and saving
`them the associated costs, and providing the consumer
`multiple points from which to downloadthe data, referred to
`herein as peers 70, 72, 74, 76, 78, thus increasing the speed
`of the download. However, each such peer-to-peer solution
`must have somesort of index by which to find the required
`data. In typical peer-to-peerfile sharing systems, because the
`index is on a server 80, or distributed amongseveral servers,
`the numberoffiles available in the system is not very large
`(otherwise, the server costs would be very large, or the
`lookup time would be very long).
`The peer-to-peer file sharing solution is acceptable in file
`sharing systems, because there are not that many mediafiles
`that are of interest to the mass (probably in the order of
`magnitude of millions of movies and songs that are of
`interest). Storing and maintaining an index of millions of
`entries is practical technically and economically. However,
`
`

`

`US 10,484,510 B2
`
`3
`if this system were to be used to serve the hundreds of
`billionsoffiles that are available on the Internet of today, the
`cost of storing and maintaining such an index would be
`again in the billions of dollars. In addition, these types of
`peer-to-peer file sharing systems are not able to deal with
`dynamic HTTP data.
`In conclusion, a system does not exist that enables fast

`incur tremendous costs, and/or that provides only a very

`
`SUMMARY OF THE INVENTION
`
`The present system and method provides for faster and
`more efficient data communication within a communication
`
`network. Briefly described, in architecture, one embodiment
`of the system, amongothers, can be implementedas follows.
`Anetwork is provided for accelerating data communication,
`wherein the network contains: at least one client communi-
`
`cation device for originating a data request for obtaining the
`data from a data server; at least one agent communication
`device which is assigned to the data server for receiving the
`data request from the client communication device, wherein
`the agent keeps track of which client communication devices
`have received responses to data requests from the assigned
`data server; at least one peer communication device for
`storing portions of data received in response to the data
`request by the at least one client communication device,
`wherein the portions of data may be transmitted to the at
`least one client communication device upon request by the
`client communication device; and at least one acceleration
`server for deciding which agent communication device is to
`be assigned to which data server and providing this infor-
`mation to the at least
