Abstract
Systems and methods for distributing content over various mediums in a service provider network are disclosed. Such mediums may include an optical fiber and a cable line having a bandwidth less than that associated with the optical fiber. In certain embodiments herein, content may be distributed over the cable line, or relatively low bandwidth medium, according to characteristics of the optical fiber, or relatively high bandwidth medium. In one embodiment, data packets may be scheduled using first in first out (FIFO) scheduling for distribution over the cable line using Orthogonal Frequency Division Multiplexing (OFDM). Using this approach, increased bandwidths may be achieved over cable lines. Additionally, certain embodiments herein are directed to maintaining a forward/reverse channel split, which may exist in a PON, over a cable line. Further, certain embodiments herein may relate to dynamic allocation of subcarriers in an OFDM signal in response to changes in quality of service.
