## Abstract

Systems and methods for transporting data between two endpoints over an encoded channel are disclosed. Data transmission units (data units) from the source network are received at an encoding component logically located between the endpoints. These first data units are subdivided into second data units and are transmitted to the destination network over the transport network. Also transmitted are encoded or extra second data units that allow the original first data units to be recreated even if some of the second data units are lost. These encoded second data units may be merely copies of the second data units transmitted, parity second data units, or second data units which have been encoded using erasure correcting coding. At the receiving endpoint, the second data units are received and are used to recreate the original first data units.

## Claims

### Claim 1

A system for improving quality of data transmission in a network path between a first and a second device comprising:
said first device sending first layer 3 data transmission unit (L3DTU) to a segmenting module coupled to said first device;
said segmenting module segmenting each first L3DTU into a plurality of second L3DTUs and adding at least one extra encoded L3DTUs when the segmenting module determines that the loss performance of the network path is below a pre-determined threshold;
said segmenting module transmitting over said network said second L3DTUs and said extra encoded L3DTUs to a reassembly module coupled to said second device; and
said reassembly module reassembling first L3DTUs from said at least two second L3DTUs and said at least one extra encoded L3DTUs received from said network before sending to said second device.

### Claim 2 (depends on 1)

The system of claim 1 wherein said extra encoded L3DTUs are redundant L3DTUs from said second L3DTUs.

### Claim 3 (depends on 2)

The system of claim 2 wherein said extra encoded L3DTUs are duplicates from said second L3DTUs.

### Claim 4 (depends on 2)

The system of claim 2 wherein said extra encoded L3DTUs are XOR from said second L3DTUs.

### Claim 5 (depends on 1)

The system of claim 1 wherein said performance of the network path is measured in packet loss.

### Claim 6

A method for improving quality of data transmission in a network path between a first and a second device comprising:
sending, at said first device, first layer 3 data transmission unit (L3DTU) to a segmenting module coupled to said first device;
segmenting, at said segmenting module, each first data transmission unit (L3DTU) into at least two second L3DTUs and adding at least one extra encoded L3DTUs when the segmenting module determines that the loss performance of the network path is below a pre-determined threshold;
transmitting, by said segmenting module, said second L3DTUs and said extra encoded L3DTUs to a reassembly module coupled to said second device over said network; and
reassembling, by said reassembly module, first L3DTUs from said at least two second L3DTUs and said at least one extra encoded L3DTUs received from said network before sending to said second device.

### Claim 7 (depends on 6)

The method of claim 6 wherein said extra encoded L3DTUs are redundant L3DTUs from said second L3DTUs.

### Claim 8 (depends on 7)

The method of claim 7 wherein said extra encoded L3DTUs are duplicates from said second L3DTUs.

### Claim 9 (depends on 7)

The method of claim 7 wherein said extra encoded L3DTUs are XOR from said second L3DTUs.

### Claim 10 (depends on 6)

The method of claim 6 wherein said performance of the network path is measured in packet loss.
