Method and device for transparent interception of socket connections
First Claim
1. A method of transmitting data packets from a server to a plurality of clients over a communication network, the method comprising, at a stream concentrator in a network device within the communication network between the plurality of clients and the server:
- inspecting a first socket connection between a first client of the plurality of clients and the server;
creating a first intercepting socket connection between the stream concentrator and the first client and a second intercepting socket connection between the stream concentrator and the server;
inspecting a second socket connection between a second client of the plurality of the clients and the server;
intercepting and blocking the second socket connection if the server is the destination of the second socket connection;
redirecting the second socket connection to the second intercepting socket connection so that data from both the first client and the second client is transmitted to the server over the second intercepting socket connection;
transmitting data received from the server over the second intercepting socket connection to the first client and the second client, wherein the data transmitted by the server is streaming data, the streaming data is a single data stream; and
inserting additional content into data transmitted from the server over the second intercepting socket connection to the first client and the second client, the additional content includes one of advertising or local information and replaces part of the streaming data with the additional content.

Abstract
A method and device is provided for managing data transmission on a network. The device includes Transparent Interceptor for transparently intercepting socket connections from first parties to one or more second parties. A signal socket connection is established to each second party. When one or more first parties request a data stream to a second party, the device distributes the data stream obtained from the second party through the single socket connection to one or more first parties. Data processor of the device may operate on data contents from the first or second party. A customized protocol may be used for the data transmission.

11. A stream concentrator for transparently intercepting and transmitting data packets between a server and a plurality of clients, the stream concentrator including a processor and located in a network device, the stream concentrator comprising:
-
a packet identifier and redirector inspecting a first socket connection between a first client of the plurality of clients and the server, and a second socket connection between a second client of the plurality of clients and the server; a client style socket endpoint providing a first intercepting socket connection between the stream concentrator and the first client; a server style socket endpoint providing a second intercepting socket connection between the stream concentrator and the server; the packet identifier and redirector further intercepting and blocking the second socket connection if the server is the destination of the second socket connection, and redirecting the second socket connection to the second intercepting socket connection so that data from both the first client and the second client is transmitted to the server over the second intercepting socket connection; a transmitter transmitting data received from the server over the second intercepting socket connection to the first client and the second client, wherein the data transmitted by the server is streaming data, the streaming data is a single data stream, wherein the packet identifier and redirector inserts additional content into data transmitted from the server over the second intercepting socket connection to the first client and the second client, the additional content includes one of advertising or local information and replaces part of the streaming data with the additional content. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
