Patent ID: 8787761

Claim:
A method for multi-service provisioning in an OFDMA-PON, said method comprising the steps of: linking communicatively to a core network; and bandwidth provisioning, dynamically within a single wavelength, traffic from said core network to a network of multiple virtual passive optical networks VPONs for multi-service provisioning to said VPONs; wherein said bandwidth provisioning comprises each participating VPON providing its requirements to a meta-MAC of its guaranteed data rate R g j , peak rate R p j and requested rate R reg j , with a relationship R g j ≦R reg j ≦R p j always holding in a meta-MAC process, and wherein with individual subcarrier rates denoted as C, a respective guaranteed, peak and requested numbers of subcarriers are given by: S g j =┌R g j /C┐+S guard , S p j =┌R p j /C┐+S guard and S reg j =┌R reg j /C┐+S guard respectively, where S guard denotes a sufficient number of unallocated subcarriers among neighboring VPONs used as a guardband to avoid unwanted interference.
