Abstract
Example embodiments describe an optical line terminal, OLT, configured to communicate with respective sets of optical network units, ONUs, within a plurality of passive optical networks, PONs, optically connected to the OLT at respective PON ports of at least one OLT line card; wherein the OLT further includes shared scheduler engine circuitry configured to allocate non-overlapping upstream transmission opportunities to traffic-bearing entities of the ONUs within the respective PONs during a shared upstream allocation interval by synchronizing the time of arrival at the OLT of the shared upstream allocation interval for the respective PONs.
Claims15
An optical line terminal, OLT, configured to communicate with respective sets of optical network units, ONUs, within a plurality of passive optical networks, PONs, optically connected to the OLT at respective PON ports of at least one OLT line card;
- wherein the OLT further comprises shared scheduler engine circuitry configured to allocate non-overlapping upstream transmission opportunities to traffic-bearing entities of the ONUs within the respective PONs during a shared upstream allocation interval by synchronizing the time of arrival at the OLT of the shared upstream allocation interval for the respective PONs.
A method for allocating non-overlapping upstream transmission opportunities to traffic-bearing entities of respective sets of optical network units, ONUs, within a plurality of passive optical networks, PONs;
- wherein the plurality of PONs are optically connected to an OLT at respective PON ports of at least one OLT line card;
- and wherein the OLT further comprises shared scheduler engine circuitry configured to allocate non-overlapping upstream transmission opportunities to traffic-bearing entities of the ONUs within the respective PONs during a shared upstream allocation interval;
- the method comprising:
- synchronizing the time of arrival of the shared upstream allocation interval at the OLT for the respective PONs.
