Abstract
Abstract A facility for mapping a plurality of different Virtual Circuit Channels (VCC) into a single VCC is provided for use in a data network. In operation, the facility assembles, in turn, data cells each having a data payload and appropriate header identifying a respective VCC into a series of data cells. The series is then segmented into a predetermined number of data payloads, and a header identifying a common connection over the network is then appended to each of the payloads. The result is then transported over the data network via the common connection.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
101 words
A method of transporting data over a data network comprising the steps of responsive to receiving a series of data cells each comprising a data payload and a header identifying a respective connection over said network, forming a first predetermined number of the data cells in the order that they are received into a string of data cells, and processing the string of data cells to form a second predetermined number of data payloads, prepending a header identifying a common connection over said network to each of the payloads and transporting each result over the data network via said common connection.
Claim 2
Independent Claim
101 words
A method of transporting data over a data network comprising the steps of responsive to receiving a series of data cells each comprising a data payload and a header identifying a respective connection over said network, forming a first predetermined number of the data cells in the order that they are received into a string of data cells, and processing the string of data cells to form a second predetermined number of data payloads, prepending a header identifying a common connection over said network to each of the payloads and transporting each result over the data network via said common connection.
Claim 3
Dependent Claim
13 words
The method of claim 1 wherein said data network is an ATM network.
Claim 4
Dependent Claim
35 words
The method of claim 1 wherein each said identification is different for each of said received series of data cells and wherein a respective connection includes a respective virtual channel identifier and virtual path identifier.
Claim 5
Dependent Claim
42 words
The method of claim 1 wherein said step of processing includes the step of appending an eight byte trailer to the string of data cells, said eight byte trailer including at least CRC code, payload length indicator and user to user information.
Claim 6
Dependent Claim
22 words
The method of claim 1 wherein said series of data cells are associated with a common virtual path connection in said network.
Claim 7
Dependent Claim
14 words
The method of claim 1 wherein said common connection is a virtual channel connection.
Claim 8
Independent Claim
115 words
A method of transporting data over a data network comprising the steps of responsive to receiving a series of data cells each comprising a data payload and a header identifying a respective connection over said network, forming a first predetermined number of the data cells in the order that they are received into a string of data cells, and processing the string of data cells to form a second predetermined number of data payloads, prepending a header identifying a common connection over said network to each of the payloads and transporting each result over the data network via said common connection, wherein said first predetermined number is eight and said second predetermined number is nine.
Claim 9
Independent Claim
115 words
A method of transporting data over a data network comprising the steps of responsive to receiving a series of data cells each comprising a data payload and a header identifying a respective connection over said network, forming a first predetermined number of the data cells in the order that they are received into a string of data cells, and processing the string of data cells to form a second predetermined number of data payloads, prepending a header identifying a common connection over said network to each of the payloads and transporting each result over the data network via said common connection, wherein said first predetermined number is eight and said second predetermined number is nine.
Claim 10
Independent Claim
109 words
A method of transporting data over a data network comprising the steps of responsive to receiving a series of data cells each comprising a data payload and a header identifying a respective connection over said network, forming a first predetermined number of the data cells in the order that they are received into a string of data cells, and processing, using an ATM Adaptation Layer No. 5 protocol, the string of data cells to form a second predetermined number of data payloads, prepending a header identifying a common connection over said network to each of the payloads and transporting each result over the data network via said common connection.
Claim 11
Independent Claim
