Abstract
Abstract Response time is improved by a method and apparatus for pre-fetching application data over a network. A request for application data, such as Internet data, is received. The request is transmitted to a transparent network proxy, which issues requests over a communications network to fetch the requested data. The requested application data are received by the proxy and forwarded to a client layered service provider, which supplies the data to the application. If additional application data is received by the proxy, that data is also forwarded to the client layered service provider, where it is stored as pre-fetch data. If additional application data is requested by the application, the additional data can be supplied from the stored pre-fetch data, if available.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
99 words
A method of requesting data over a network, comprising the steps of: receiving a request for a predetermined amount of application data from an application; converting said request to include an additional amount of pre-fetch application data; transmitting the request to a network proxy; receiving said predetermined amount of application data from the network proxy in response to said request; supplying said predetermined amount of application data to the application; receiving said additional amount of pre-fetch application data from the network proxy in response to said-request; and storing said additional amount of pre-fetch data; without modification of the application.
Claim 2
Independent Claim
99 words
A method of requesting data over a network, comprising the steps of: receiving a request for a predetermined amount of application data from an application; converting said request to include an additional amount of pre-fetch application data; transmitting the request to a network proxy; receiving said predetermined amount of application data from the network proxy in response to said request; supplying said predetermined amount of application data to the application; receiving said additional amount of pre-fetch application data from the network proxy in response to said-request; and storing said additional amount of pre-fetch data; without modification of the application.

Dependent Claim
15 words
The method of claim 1 , wherein the network is an AC power line network.
Claim 4
Dependent Claim
65 words
The method of claim 1 , further comprising the steps of: receiving from the application a request for additional application data; determining if the requested additional application data has previously been obtained and stored as pre-fetch data; and supplying to the application the additional application data from the stored pre-fetch data if the additional application data has previously been obtained and stored as pre-fetch data.
Claim 5
Dependent Claim
52 words
The method of claim 3 , further comprising the steps of: determining if the amount of stored pre-fetch data has fallen below said pre-determined amount; and requesting and receiving additional pre-fetch data from the network proxy if the amount of stored pre-fetch data has fallen below the pre-determined amount of pre-fetch data.
Claim 6
Dependent Claim
14 words
The method of claim 1 , wherein the network proxy is a transparent proxy.
Claim 7
Dependent Claim
22 words
The method of claim 1 , wherein said steps of receiving and requesting are performed using a WinSock transport layered service provider.
Claim 8
Dependent Claim
21 words
The method of claim 5 , wherein the transparent proxy obtains the requested application data and pre-fetch data from the Internet.
Claim 9
Dependent Claim
82 words
The method of claim 6 , wherein the network proxy performs steps comprising: receiving the request for application data from the WinSock transport layered service provider; issuing requests over a communications network to fetch the requested application data; receiving the requested application data from the communications network; forwarding the requested application data to the WinSock transport layered service provider; receiving additional pre-fetch application data from the communication network; and forwarding the additional pre-fetch application data to the WinSock transport layered service provider.
Claim 10
Independent Claim
108 words
An apparatus for requesting data over a network, comprising: an application unit configured to generate an application data request; a client communications port configured to transmit the application data request and receive application data; a client layered service provider unit configured to: transmit the application data request through the client communications port; convert said application data request to include additional pre-fetch application data; receive said application data through the communications port, in response to said application data request; supply said application data to the application unit; receive said additional pre-fetch application data through the communications port, in response to said application data request; and store the pre-fetch data.
Claim 11
Independent Claim
108 words
An apparatus for requesting data over a network, comprising: an application unit configured to generate an application data request; a client communications port configured to transmit the application data request and receive application data; a client layered service provider unit configured to: transmit the application data request through the client communications port; convert said application data request to include additional pre-fetch application data; receive said application data through the communications port, in response to said application data request; supply said application data to the application unit; receive said additional pre-fetch application data through the communications port, in response to said application data request; and store the pre-fetch data.
