Abstract
Abstract A method for coordinating and controlling multiple data streams representing a data transmission session that terminate in different termination units (such as network access servers). The data streams are transmitted over two or more links, collectively forming a "bundle". The termination units are linked together preferably over a local area network. One of the termination units that receives a data stream is designated as the termination unit to receive and reconstruct the call. The designated termination unit is the "owner" of the bundle. The termination unit broadcasts an advertisement consisting of a bundle mapping update packet software structure with an identification header to alert the other termination units that it is to reconstruct the call. The identification header in the advertisement notifies the other termination units that if they should receive a portion of the data stream in the bundle, they should forward their packets of data to the designated termination unit. The sharing of bundle information between the termination units gives a great deal of flexibility in the design and type of termination units that may be employed.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
132 words
A method of coordinating the reconstruction of a plurality of data streams representing a session, said data streams generated by a source and transmitted to a destination over a plurality of links collectively forming a bundle, said data streams terminating at a first termination unit and at a second termination unit, comprising the steps of: designating one of said first and second termination units as a designated termination unit for said bundle; generating a bundle mapping update packet identifying said designated termination unit and transmitting said bundle mapping update packet from said designated termination unit to the other of said first and second termination units; and collecting said streams of data at said designated termination unit, said designated termination unit reconstructing said data streams and directing said data streams to said destination.
Claim 2
Independent Claim
132 words
A method of coordinating the reconstruction of a plurality of data streams representing a session, said data streams generated by a source and transmitted to a destination over a plurality of links collectively forming a bundle, said data streams terminating at a first termination unit and at a second termination unit, comprising the steps of: designating one of said first and second termination units as a designated termination unit for said bundle; generating a bundle mapping update packet identifying said designated termination unit and transmitting said bundle mapping update packet from said designated termination unit to the other of said first and second termination units; and collecting said streams of data at said designated termination unit, said designated termination unit reconstructing said data streams and directing said data streams to said destination.
Claim 3
Dependent Claim
37 words
The method of claim 1, wherein said step of designating said termination unit comprises the step of designating as the designated termination unit the termination unit that first receives one of said data streams from said source.
Claim 4
Dependent Claim
34 words
The method of claim 1, wherein the method further comprises the step of sharing bundling information with a supervisory controller, said supervisory controller controlling the collection of said bundles at said designated termination unit.
Claim 5
Dependent Claim
21 words
The method of claim 1, wherein said data streams are transmitted over an ISDN line from said source to said destination.
Claim 6
Dependent Claim
34 words
The method of claim 1, wherein said first and second termination units are linked together over a local area network, and wherein said sharing of bundling information is shared over said local area network.
Claim 7
Dependent Claim
16 words
The method of claim 1, wherein said first and second termination units comprises network access servers.
Claim 8
Dependent Claim
20 words
The method of claim 6, wherein said communications medium comprises a local area network connecting said network access servers together.
Claim 9
Dependent Claim
21 words
The method of claim 1, wherein said data streams are transmitted over a T-1 line from said source to said destination.
Claim 10
Dependent Claim
33 words
The method of claim 1, wherein a supervisory unit connected to said first and second termination units via said communications medium controls the transmission of said data streams to said designated termination unit.
Claim 11
Independent Claim
213 words
A system for coordinating the reconstruction of a plurality of data streams including a first data stream and a second data stream, said first and second data streams representing a session generated by a source and transmitted over a plurality of links collectively forming a bundle, the system comprising: a first termination unit for receiving said first data stream; a second termination unit for receiving said second data stream; a communications medium connecting said first and second termination units; one of said first and second termination units designated as a designated termination unit for receiving and reconstructing said first and second data streams; a means for generating a bundle mapping update packet from said designated termination unit and forwarding said bundle mapping update packet to the other of said first and second termination units over said communications medium; said bundle mapping update packet having a field identifying one of said first and said second termination units as said designated termination unit to receive the data stream from the other of said first and second termination units and reconstruct said first and second data streams; whereby said designated termination trait receives said data stream from the other of said first and second termination units and reconstructs said data streams for transmission to a destination.
Claim 12
Independent Claim
213 words
A system for coordinating the reconstruction of a plurality of data streams including a first data stream and a second data stream, said first and second data streams representing a session generated by a source and transmitted over a plurality of links collectively forming a bundle, the system comprising: a first termination unit for receiving said first data stream; a second termination unit for receiving said second data stream; a communications medium connecting said first and second termination units; one of said first and second termination units designated as a designated termination unit for receiving and reconstructing said first and second data streams; a means for generating a bundle mapping update packet from said designated termination unit and forwarding said bundle mapping update packet to the other of said first and second termination units over said communications medium; said bundle mapping update packet having a field identifying one of said first and said second termination units as said designated termination unit to receive the data stream from the other of said first and second termination units and reconstruct said first and second data streams; whereby said designated termination trait receives said data stream from the other of said first and second termination units and reconstructs said data streams for transmission to a destination.
Claim 13
Dependent Claim
14 words
The system of claim 10, wherein said communications medium comprises a local area network.
Claim 14
Dependent Claim
20 words
The system of claim 10, wherein said call is transmitted from said source to said destination over an ISDN line.
Claim 15
Dependent Claim
21 words
The system of claim 10, wherein said data streams are transmitted over a T-1 line from said source to said destination.
