System and method for implementing application functionality within a network infrastructure
A system and method for implementing functionality within a network on behalf of first and second computers communicating with each other through the network. A front-end computer is provided within the network having an interface for communicating data traffic with the first computer. A back-end computer is also implemented within the network having an interface for communicating data traffic with the second computer. A communication channel couples the front-end computer and the back-end computer. Data traffic is encoded over the communication channel in a first process in the front-end computer. Data traffic is also encoded over the communication channel in a second process in the back-end computer, wherein the first process and the second process implement compatible semantics.

wherein the front-end server and the back-end server are time synchronized and the back-end server comprises means for ascertaining when a request/response was issued by the front-end server.
7. The system of claim 6 wherein the front-end server and back-end server are time synchronized and the front-end server comprises means for ascertaining when a request/response was issued by the back-end server.
8. The system of claim 6 wherein the front-end server and back-end server include compression mechanisms for compressing traffic transported across the communication channel.
9. The system of claim 6 wherein the front-end server and back-end server include encryption mechanisms for encrypting traffic transported across the communication channel.
10. The system of claim 6 wherein the front-end server and back-end server include forward error correcting mechanisms for error correcting traffic transported across the communication channel.
11. A system for transporting data through a network comprising:
a plurality of network-connected applications generating requests for network services;
a plurality of network-connected computers configured to provide services in response to received requests;
a plurality of front-end web computers each having at least one interface configured to handle request/response traffic with the network-connected applications;
a plurality of back-end web computers each having at least one interface configured to handle request/response traffic with a selected set of the network-connected computers; and
