`ABSTRACT
`A system designed for increasing network communication
`speed for users , while lowering network congestion for
`content owners and ISPs . The system employs network
`elements including an acceleration server , clients , agents ,
`and peers , where communication requests generated by
`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 some or all 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 .

`
`FIELD OF THE INVENTION
`The present invention is related to Internet communica
`tion , and more particularly , to improving data communica
`tion speed and bandwidth efficiency on the Internet .
`BACKGROUND OF THE INVENTION
`
`2
`prehensive solution . Many of these attempts are lacking in
`that much of the 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
`CROSS - REFERENCE TO RELATED
`seen on the Amazon Web site and the Salesforce Web site ,
`APPLICATIONS
`for example , where most of the page views on these Web
`sites is tailored to the viewer , and is thus different for any
`The present application is a continuation application of
`two viewers . This dynamic information makes it impossible
`U.S. non - provisional patent application Ser . No. 15 / 957,945 ,
`for most of the solutions offered to date to store the content
`filed Apr. 20 , 2018 , which is a continuation application of
`U.S. non - provisional patent application Ser . No. 14 / 025,109 , 10 and provide it to others seeking similar content .
`One solution that has been in use is called a " proxy ” . FIG .
`filed Sep. 12 , 2013 and issued as U.S. Pat . No. 10,069,936
`1 is a schematic diagram providing an example of use of a
`on Sep. 4 , 2018 , which is a divisional application of U.S.
`non - provisional patent application entitled “ SYSTEM AND
`proxy within a network 2. A proxy , or proxy server 4 , 6 , 8
`METHOD FOR PROVIDING FASTER . AND MORE is a device that is placed between one or more clients ,
`EFFICIENT DATA COMMUNICATION ” having Ser . No. 15 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
`12 / 836,059 , filed Jul . 14 , 2010 and issued as U.S. Pat . No.
`8,560,604 on Oct. 15 , 2013 , and claims priority to U.S.
`Web servers 30 , 32 , 34 from which they are requesting the
`provisional patent application entitled “ SYSTEM AND
`data . The proxy server 4 , 6 , 8 requests the data from the Web
`METHOD FOR REDUCING INTERNET CONGES
`servers 30 , 32 , 34 on their behalf , and caches the responses
`TION , ” having Ser . No. 61 / 249,624 , filed Oct. 8 , 2009 , 20 from the Web servers 30 , 32 , 34 , to provide to other client
`devices that make similar requests . If the proxy server 4 , 6 ,
`which are hereby incorporated herein by reference in their
`8 is geographically close enough to the client devices 10 , 12 ,
`entirety .
`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
`25 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
`30 world where the Internet is being consumed , and the storage
`size of the proxy servers at each location would need to be
`near the size of all the data stored anywhere on the Internet .
`There are several trends in network and Internet usage ,
`The abovementioned would lead to massive costs that are
`which tremendously increase the bandwidth that is being
`impractical . In addition , these proxy solutions cannot deal
`used on the Internet . One such trend is that more and more
`video is being viewed on demand on the Internet . Such 35 well with dynamic data that is prevalent now on the Web .
`viewing includes the viewing of both large and short video
`There have been commercial companies , such as Akarnai ,
`clips . In addition , regular shows and full - featured films may
