Abstract

A system and method for efficiently and quickly handling content and transaction requests from various users at respective end terminals. According to embodiments of the invention, plural servers are provided at the web site to randomly receive requests from users over a communications network, such as the Internet. Each server contains a memory, such as a cache or disk storage process, that contains a copy of all data contained on every other server. When a request comes in to one of the servers, in addition to processing the request, that server broadcasts data corresponding to the request to the other servers, which are programmed to store the same request data in their respective local memories. Such broadcasts may be preferably carried out over a back-end, private network.

Claims

1. A system for interacting with end user terminals over a first communications network, the system comprising:

a plurality of servers coupled to receive communication from the end user terminals over the first communications network;

an interface disposed between the plurality of servers and end user terminals, the interface being operative to receive requests from the end user terminals and to distribute the requests to the plurality of servers;

a second communication network coupled to provide communication between the servers in the plurality of servers;

a first computer program segment resident in at least one of the plurality of servers wherein said program;

receives a request from an end user terminal,

process the request, and

broadcasts data regarding the processed request to the other servers,

a second computer program segment resident in at least one of the plurality of servers wherein the said program stores data broadcast from at least one other server.

2. The system of claim 1, wherein the first program segment broadcasts data over the second communication network to the second program segment.

3. The system of claim 2, wherein the second communications network comprises an Ethernet network.

4. The system of claim 3, wherein the second communications network comprises a gigabit Ethernet network.

5. The system of claim 1, wherein the end user terminals comprise ITV receivers, and wherein the requests from the end user terminals are requests from the ITV receivers to retrieve and transmit interactive content to the ITV receivers.

6. The system of claim 1, further including a database for permanent storage of the data relating to processed requests.

7. The system of claim 6, wherein the database is coupled to the second communications network.

8. The system of claim 1, wherein the interface disposed between the plurality of servers and end user terminals further includes means for routing incoming requests to the respective servers.

9. The system of claim 8, wherein the means for routing comprises the Domain Name Server function of the Internet.

10. The system of claim 8, wherein the means for routing comprises a load balancing system (LBS).
