摘要： A method, apparatus and computer program product for reducing the data transmitted over an external communication link from a first application resident in a first computer to a second application resident in a second computer. The method, apparatus and computer program product include storing a data stream from the first application to be provided to the second application in response to a request from the second application in a cache resident in the first computer to create a server base cache entry and in a cache resident in the second computer to create a client base cache entry. Requests from the second application are interrogated to determine if a client base cache entry corresponding to the interrogated request exists and to determine if a server base cache entry corresponding to the interrogated request exists. The response data stream is intercepted prior to transmission of the response on the external communication link and compared to the server base cache entry to provide difference data corresponding to the difference between the intercepted response and the server base cache entry. The difference data is sent over the external communication link and acquired by the second computer which reconstructs the response data stream by combining the client base cache entry with the difference data to create a response data stream which is provided to the second application.

摘要： A method, apparatus and computer program product for reducing the data transmitted over an external communication link using the TCP protocol from a first application resident in a first computer and to a second application resident in a second computer. The method, apparatus and computer program product include establishing a first virtual socket in the first computer in response to each connection request by the first application for receiving request data originated by the first application. A first real socket in the first computer and a second real socket in the second computer are established to connect the first computer to the second computer over the external communication link and are maintained until the request data has been provided to the second application. In the second computer a second virtual socket is established for each connection request by the first application wherein the second virtual socket corresponds to a first virtual socket established in the first computer in response to a connection request by the first application. Request data associated with a first virtual socket is multiplexed onto the first real socket and transmitted over the external communication link utilizing the TCP protocol. The multiplexed request data is received from the external communication link by the second real socket and demultiplexed. The demultiplexed request data is provided to the corresponding second virtual socket which provides the request data to the second application.

摘要： A method, apparatus and computer program product for reducing the data transmitted over a communication link from a first application resident in a first computer and to a second application resident in a second computer wherein the data is transmitted over an external communication link. HTML data in response to specific data in a CGI request is stored in a cache resident in the first computer to create a server base cache entry. HTML data in response to the specific data in the CGI request is also stored in a cache resident in the second computer to create a client base cache entry. CGI requests and specific CGI data is evaluated to determine if a corresponding client base cache entry exists to provide a client base form. CGI requests and specific CGI data are interrogated to determine if a server base cache entry exists to provide a server base form. The data stream corresponding to the response HTML data is intercepted and compared to the server base form to provide difference data. The difference data is then sent to the second computer over the external communication link. The response HTML data is reconstructed from the client/server specific data stream received over the external communication link by combining the client base form with the difference data and provided to the second application. Creation of an extended cache key corresponding to the CGI form and the user input data is also provided.

摘要： A method, apparatus and program product for increasing the performance of a client/server system having a client application resident on a first computer and communicating with a server application resident on a second computer remote from the first computer. The client application and the server application utilize a client/server independent communication protocol for communication between the client and the server and at least one segment of the communication between the client application in the first computer and the server application in the second computer occurs over an external communication link. The method, apparatus and program product intercept communications in the client/server independent communication protocol originated by the remote client prior to transmission of the communications on the external communication link and convert the communication originated by the client to a second client/server specific communication protocol. The converted communication is transmitted over the external communication link and received from the communication transmitted over the external communication link. The communication received over the external communication link is converted from the client server specific communication protocol to the client/server independent communication protocol and the communication originated by the remote client is provided to the server in the client/server independent communication protocol. Differencing, caching or protocol reduction techniques increase performance over the external communication link. The applications may be a web browser and a web server and may communicate over a wireless communication link.

摘要： Method, apparatus and program products for increasing the performance of communications of a terminal emulator application resident on a first computer and communicating over an external communication link using a terminal emulator protocol with a host application resident on a second computer remote from the first computer are provided. A protocol interceptor is provided on both the host side and the terminal emulator application side of the external communication link to provide communications over the external communication link using a differenced communication protocol data stream which includes a reduced volume of data for transmittal compared to the corresponding terminal emulator protocol data stream. The reduction in volume in the differenced communication protocol data stream is based on recognition and replacement of data segments which have previously been transmitted by the host application. The terminal emulator protocol data stream from the host application is intercepted and converted to the differenced communication protocol data stream before transmission. The differenced communication protocol data stream is received at the terminal emulator application computer and reconstructed into a terminal emulator protocol data stream which is provided to the terminal emulator application. The continuous terminal emulator protocol data stream may be segmented and calculating an identifier for each segment calculated. If the segment corresponds to a segment saved on a cache present on the receiving computer, the segment is replaced with the identifier for transmission over the external communication line. The saved segment from the cache one the receiving computer is inserted in the data stream in place of the identifier.
