Abstract

A network component comprising a processor configured to implement a method comprising promoting the communication of a frame of octet-sized timeslots, wherein the timeslots are configured to carry a plurality of data types. Also disclosed is a method comprising communicating a high priority data and a low priority data in a frame comprising a plurality of octet-sized timeslots, wherein each timeslot is assigned to the high priority data or the low priority data, wherein the high priority data is provided in the timeslots assigned to the high priority data, and wherein the low priority data is provided in the timeslots assigned to the low priority data. Also disclosed is a network component comprising a processor configured to implement a method comprising recognizing the reception of a plurality of data streams each having a priority, and promoting the multiplexing of the data streams based on the priority of each data stream.

Claims

1. A network component comprising:

a processor configured to implement a method comprising;

promoting the communication of a frame of octet-sized timeslots, wherein the timeslots are configured to carry a plurality of data types.

2. The network component of claim 1, wherein the data types comprise at least one of a time division multiplexed (TDM) data, a high performance flow (HPF) data, or a best-effort packet (BEP) data.

3. The network component of claim 2, wherein some of the timeslots are reserved for the TDM data, and wherein the BEP data is not transmitted in the timeslots reserved for the TDM data.

4. The network component of claim 2, wherein the TDM data comprises telephonic voice data and the BEP data comprises an Ethernet data.

5. The network component of claim 1, wherein the method further comprises promoting the communication of a low priority data prior to the frame, subsequent to the frame, or both.

6. The network component of claim 1, wherein the frame is communicated within a synchronization window having a predefined period.

7. The network component of claim 6, wherein the period is about 125 microseconds, and wherein each timeslot in the data stream provides about 64 kilobits per second of bandwidth.

8. The network component of claim 6, wherein the frame further comprises a control portion.

9. The network component of claim 8, wherein the control portion comprises a synchronization data and a timeslot map, and wherein the timeslot map describes the data types assigned to the timeslots.

10. The network component of claim 9, further comprising utilizing the synchronization data to establish the synchronization window.

11. A method comprising:

communicating a high priority data and a low priority data in a frame comprising a plurality of octet-sized timeslots,

wherein each timeslot is assigned to the high priority data or the low priority data,

wherein the high priority data is provided in the timeslots assigned to the high priority data, and

wherein the low priority data is provided in the timeslots assigned to the low priority data.

12. The method of claim 11, wherein at least some of the timeslots assigned to the high priority data communicate a telephonic voice channel.

13. The method of claim 11, wherein at least some of the timeslots assigned to the high priority data communicate at least one of a high performance flow data, a real-time data, an audio data, a video data, or a multimedia data.

14. The method of claim 11, wherein at least some of the timeslots assigned to the low priority data communicate at least part of an Ethernet packet.

15. The method of claim 14, wherein the timeslots that communicate the Ethernet packet are not consecutive within the frame.

16. The method of claim 11, wherein the frame is communicated within a synchronization window having a period of about 125 microseconds, and wherein each timeslot in the frame provides about 64 kilobits per second of bandwidth.

17. A network component comprising:

a processor configured to implement a method comprising;

recognizing the reception of a plurality of data streams each having a priority; and

promoting the multiplexing of the data streams based on the priority of each data stream.

18. The network component of claim 17 wherein the data streams comprise a plurality of best effort packet (BEP) data streams.

19. The network component of claim 17 wherein the data streams are multiplexed at the octet level.

20. The network component of claim 17 wherein the data streams comprise a time division multiplexed (TDM) data stream, a high performance flow (HPF) data stream, a best-effort packet (BEP) data stream, or combinations thereof.
