Abstract
A method and apparatus are provided for scheduling the transmission of cells and frames in a communications network. The transmission of cells and frames are scheduled utilizing a selected scheduling algorithm. The cell/frame scheduling algorithm includes the step of identifying a frame or cell transmission type. Responsive to the identified frame or cell transmission type, a frame multiplier value is identified. A target transmission time is calculated for the frame or cell transmission type utilizing the identified frame multiplier value. A method and apparatus optionally are provided for scheduling the transmission of packet pairs.
Claims17
An computer program product for scheduling communications over a communications network including both cells and frames, said program product comprising a plurality of processor-executable instructions recorded on a computer-readable medium, wherein said instructions, when executed by a computer processor, perform the steps of:
- scheduling the transmission of cells and frames utilizing a selected scheduling algorithm including the steps of:
- identifying a frame or cell transmission type;
- responsive to said identified frame or cell transmission type, identifying a frame multiplier value;
- calculating a target transmission time for said frame or cell transmission type utilizing said identified frame multiplier value.
A method for scheduling communications over a communications network including both cells and frames comprising the steps of:
- scheduling the transmission of cells and frames utilizing a selected scheduling algorithm including the steps of:
- identifying a frame or cell transmission type;
- responsive to said identified frame or cell transmission type, identifying a frame multiplier value;
- calculating a target transmission time for said frame or cell transmission type utilizing said identified frame multiplier value.
An apparatus for scheduling communications over a communications network comprising:
- means for identifying a last transmission opportunity used for a frame;
- means, responsive to said identified last transmission opportunity used for said frame, for updating a logical channel descriptor (LCD) to a next frame;
- means for checking a frame header for a packet pair bit being set;
- and
- means, responsive to an identified packet pair bit not being set, for calculating a target transmission time for said frame utilizing a frame multiplier value.
