Abstract

Interactive internet activities are a very popular means for gathering information for business, personal, medical, entertainment and other purposes. Most internet interaction is asymmetrical in nature in that a client'"'"'s requests for information are much smaller (in data size) than the resulting information delivered by the server. Although the client/internet link is inherently asymmetrical, there remains a great deal of interaction and overhead required between the client and the server that increases the bandwidth needs for the client'"'"'s upstream request channel. There are many advantages to reducing this upstream traffic volume and thereby making the internet interaction even more asymmetrical. Such compression of request data could allow more clients to utilize a single upstream data path instead of separate paths.

Claims

1. In an interactive internet information distribution system in which user stations are connected to the internet by an internet server through an upstream gateway for transmission of information requests to said internet server and downstream gateways for transmission of information from the internet server to the user stations, the improvement wherein each user station includes a processor, said processor including:

(a) means for interfacing with the user,

(b) an internet browser module connected to said interfacing means,

(c) internet driver means connected to said internet browser means,

(d) compression module connected to said internet driver means for reducing the upstream traffic whereby the ratio of downstream to upstream channel traffic is increased beyond a 20;

1 ratio and wherein said upstream gateway includes means for storing a profile of the users connected thereto.

5. The information distribution system defined in claim 1 wherein said upstream gateway includes means for automatically generating a new data request for a given user.

2. In an interactive internet information distribution system in which user stations are connected to the internet by an internet server through an upstream gateway for transmission of information requests to said internet server and downstream gateways for transmission of information from the internet server to the user stations, the improvement wherein each user station includes a processor, said processor including:

(a) means for interfacing with the user,

(b) an internet browser module connected to said interfacing means,

(c) internet driver means connected to said internet browser means,

(d) compression module connected to said internet driver means for reducing the upstream traffic whereby the ratio of downstream to upstream channel traffic is increased beyond a 20;

1 ratio and wherein said upstream gateway is adapted to perform protocol overhead functions and includes means for storing a profile of the users connected thereto.

4. The information distribution system defined in claim 2 wherein said upstream gateway includes means for automatically generating a new data request for a given user.

3. In an interactive internet information distribution system in which user stations are connected to the internet by an internet server through an upstream gateway for transmission of information requests to said internet server and downstream gateways for transmission of information from the internet server to the user stations, the improvement wherein each user station includes a processor, said processor including:

(a) means for interfacing with the user,

(b) an internet browser module, connected to said interfacing means,

(c) internet driver means connected to said internet browser means,

(d) compression module connected to said internet driver means for reducing the upstream traffic whereby the ratio of downstream to upstream channel traffic is increased beyond a 20;

1 ratio and wherein said upstream gateway includes means for automatically generating a new data request for a given user.
