Abstract

A method of fragmented packet reception in a multiple-channel passive optical network (PON). The method includes receiving, at a receiver, a plurality of encapsulated packet fragments over a plurality of channels. Each packet fragment of the plurality of packet fragments comprises a header. The method also includes assembling the plurality of packet fragments according to arrival times of respective headers of the plurality of packet fragments. The method further includes buffering, by a processor, the plurality of packet fragments in a sequence based on the arrival times of the respective headers.

First claim

What is claimed is:

1. A method of fragmented packet reception in a multiple-channel passive optical network (PON), comprising:
receiving, at a receiver, a plurality of encapsulated packet fragments over a plurality of channels, each packet fragment of the plurality of packet fragments comprising a header;
receiving an end of packet (EoP) indicator in a packet fragment, wherein the EoP indicator indicates that the packet fragment is a last packet fragment in a frame, the frame being a GEM/XGEM frame;
assembling the plurality of packet fragments according to arrival times of respective headers of the plurality of packet fragments; and
buffering, by a processor, the plurality of packet fragments in a sequence based on the arrival times of the respective headers.

2. The method of claim 1 , further comprising decapsulating the plurality of encapsulated packet fragments.

3. The method of claim 1 , wherein assembling the plurality of packet fragments comprises reassembling a frame based on the respective headers of the plurality of packet fragments.

4. The method of claim 1 , with the receiver receiving the plurality of packet fragments at a port of the plurality of channels.

5. A method of fragmented packet reception in a multiple-channel passive optical network (PON), comprising:
receiving, at a receiver, a plurality of encapsulated packet fragments over a plurality of channels, each packet fragment of the plurality of packet fragments comprising a header;
assembling the plurality of packet fragments according to arrival times of respective headers of the plurality of packet fragments by reassembling a frame based on the respective headers of the plurality of packet fragments and based on a port of the plurality of channels receiving the respective packet fragments; and
buffering, by a processor, the plurality of packet fragments in a sequence based on the arrival times of the respective headers.

6. A network element configured for fragmented packet reception in a multiple-channel passive optical network (PON), comprising:
a receiver configured to receive:
a plurality of encapsulated packet fragments over a plurality of channels, each packet fragment of the plurality of packet fragments comprising a header; and
an end of packet (EoP) indicator in a packet fragment, wherein the EoP indicator indicates that the packet fragment is a last packet fragment in a frame, the frame being a GEM/XGEM frame;

a processor coupled to the receiver, the processor configured to:
assemble the plurality of packet fragments according to arrival times of respective headers of the plurality of packet fragments; and
buffer the plurality of packet fragments in a sequence based on the arrival times of the respective headers.

7. The network element of claim 6 , wherein the processor is further configured to decapsulate the plurality of encapsulated packet fragments.

8. The network element of claim 6 , wherein the processor is configured to assemble the plurality of packet fragments by reassembling a frame based on the respective headers of the plurality of packet fragments.

9. The network element of claim 6 , wherein the receiver is configured to receive the plurality of packet fragments at a port of the plurality of channels.

10. A network element configured for fragmented packet reception in a multiple-channel passive optical network (PON), comprising:
a receiver configured to receive a plurality of encapsulated packet fragments over a plurality of channels and at a port of the plurality of channels, each packet fragment of the plurality of packet fragments comprising a header;
a processor coupled to the receiver, the processor configured to:
assemble the plurality of packet fragments according to arrival times of respective headers of the plurality of packet fragments;
reassemble a frame based on the respective headers of the plurality of packet fragments and based on the port receiving the plurality of packet fragments; and
buffer the plurality of packet fragments in a sequence based on the arrival times of the respective headers.
