摘要： A system and method for applying an extended multipoint control protocols to wireless access systems. A medium-to-medium adaptor can be provided in an adaptor node that can interface with an upstream optical line terminal in a PON domain and a downstream device in a non-PON wireless domain. The medium-to-medium adaptor enables an implementation of end-to-end services across multiple quality of service (QoS) domains by passing all traffic with controlled delay and without contention.

摘要： One embodiment of the present invention provides a method for facilitating asymmetric line rates in an Ethernet passive optical network (EPON) which includes a central node and at least one remote node. During operation, the system provides a downstream code-group clock, wherein each cycle thereof corresponds to a code group transmitted from the central node to a remote node. The system also provides an upstream code-group clock, wherein each cycle thereof corresponds to a code group received at the central node from a remote node. In addition, the system provides a multi-point control protocol (MPCP) clock, wherein the frequency ratio of the MPCP clock to the downstream code-group clock is different from the frequency ratio of the MPCP clock to the upstream code-group clock, thereby allowing the downstream transmission to be performed at a faster line rate than the upstream transmission line rate.

摘要： One embodiment of the present invention provides a system for mitigating Raman crosstalk between downstream data and video transmission in an Ethernet passive optical network (EPON), wherein the EPON includes an optical line terminal (OLT) and one or more optical network units (ONU's). During operation, the system transmits a data stream from the OLT to the ONU's on a first wavelength that is substantially at 1490 nm. The system also transmits a video signal stream from the OLT to the ONU's on a second wavelength that is substantially at 1550 nm. The system modifies the bit sequence for the data stream to change the power spectral distribution (PSD) for the data stream, thereby reducing power spectral content in the frequency range where significant Raman crosstalk can occur between data and video signal streams.
