Duplicating switch for streaming data units to a terminal
First Claim
Patent Images
1. A method of streaming data units to terminals, the method comprising:
- using a duplicating switch to receive communications;
using the duplicating switch to selectively filter the communications;
receiving a received stream of data units at the duplicating switch, wherein the received stream is addressed to a unicast address associated with the duplicating switch and the data units include a payload portion and an attribute portion;
using the duplicating switch to store content from the payload portion of the received stream;
using the duplicating switch to generate forwarded streams that incorporate the content for use by two or more terminals having address information that was not part of the received stream; and
in response to a request received at the duplicating switch, using the duplicating switch to forward the forwarded streams that incorporates the content, with each forwarded stream being forwarded to a unicast address of each of the two or more terminals,wherein the duplicating switch is structured and arranged to selectively filter the communications and forward the forwarded streams based on address information sent in the request to the duplicating switch.

Abstract
Streaming to a terminal by using a duplicating switch to receive a stream of data units, using the duplicating switch to store content from the stream, using the duplicating switch to generate a second stream that incorporates the content that was stored and address information corresponding to more than one terminal whose addressing information was not part of the first stream, and using the duplicating switch to make the second stream of data units available to two or more terminals.

13. A duplicating switch comprising:
-
means for using a duplicating switch to receive communications; means for using the duplicating switch to selectively filter the communications; means for receiving a received stream of data units that is addressed to a unicast address associated with the duplicating switch, wherein the data units include a payload portion and an attribute portion; means for storing content from the payload portion of the received stream; means for generating forwarded streams that incorporate the content for use by two or more terminals having address information that was not part of the received stream; and means for using the duplicating switch to forward the forwarded streams of data units that incorporates the content, each forwarded stream being forwarded to a unicast address of each of the two or more terminals, in response to a request received at the duplicating switch, wherein the duplicating switch is structured and arranged to selectively filter the communications and forward the forwarded streams based on address information sent in the request to the duplicating switch. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A duplicating switch comprising:
-
a first communications interface structured and arranged to; receive communications, selectively filter the communications, and receive a received stream of data units that are addressed to a unicast address associated with the duplicating switch, wherein each data unit includes a payload portion and an attribute portion; a storage processor structured and arranged to store content from the payload portion of the received stream; a switching processor structured and arranged to generate forwarded streams that incorporate the content for use by two or more terminals having address information that was not part of the received stream, and a second communications interface structured and arranged to forward the forwarded streams that incorporate the content in response to a request received at the duplicating switch, each forwarded stream being forwarded to a unicast address of each of the two or more terminals, wherein the duplicating switch is structured and arranged to selectively filter the communications and forward the forwarded stream based on address information sent in the request to the duplicating switch. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
