Abstract

A network component comprising a processor configured to implement a method comprising promoting the communication of a frame within a synchronization window, wherein the frame comprises a plurality of data types carried in a plurality of timeslots, and wherein each timeslot is assigned to carry one of the data types, identifying an idle timeslot that is assigned to carry a first data type, and inserting a second data type into the idle timeslot. Also disclosed is a method comprising receiving a data stream comprising a plurality of timeslots, wherein each timeslot is assigned to carry one of a plurality of data types, and determining whether one of the timeslots assigned to carry a first data type contains a second data type.

Claims

1. A network component comprising:

a processor coupled to a memory and configured to implement a method comprising;

promoting the communication of a frame within a synchronization window, wherein the frame comprises a plurality of data types carried in a plurality of timeslots, and wherein each timeslot is assigned to carry one of the data types;

identifying an idle timeslot that is assigned to carry a first data type; and

inserting a second data type into the idle timeslot,

wherein the second data type is part of a second data type stream, and wherein the method further comprises;

identifying an active timeslot following the idle timeslot, the active timeslot assigned to carry the first data type; and

interrupting the second data type stream by inserting the first data type into the active timeslot.

2. The network component of claim 1:

wherein the timeslots assigned to carry the first data type comprise an indication of whether the timeslots are active timeslots or idle timeslots, and

wherein the indication is used to identify the idle timeslot.

3. The network component of claim 2, wherein the indication is provided by a first bit of the timeslots assigned to carry the first data type.

4. The network component of claim 3, wherein the active timeslots have the first bit set to one and the idle timeslots have the first bit set to zero.

5. The network component of claim 1, wherein inserting the second data type into the idle timeslot occurs immediately upon identifying the idle timeslot.

6. The network component of claim 1, wherein the synchronization window has a period of about 125 microseconds, and wherein each of the timeslots provide about 64 kilobits per second of bandwidth.

7. The network component of claim 1, wherein the first data type is a high performance flow data, and wherein the second data type is a best-effort packet data.

8. The network component of claim 1 wherein the timeslots are octets.
