3 results about "Multi point control protocol" patented technology

Apparatus and methods for discovery, synchronization and operation of network components. In one embodiment, the network comprises a passive optical network (PON), and the components being synchronized include an enhanced OLT (eOLT) and one or more enhanced ONUs (eONUs). The eOLT is configured in one variant to utilize control protocol messaging (such as those used in the MPCP or Multi Point Control Protocol) to communicate particular synchronization parameters and durations to the eONU(s), whether individually or via multicast / broadcast. The synchronization parameter and durations are selected to optimize discovery and synchronization of the eONU(s) with the eOLT, and also optimize (subsequent) normal operation, in one implementation through selection of synchronization patterns which enable most efficient AGC determination, clock recovery (CDR), SBD, and EBD identification.

A method for facilitating Coordinated Multipoint Transmission (COMP) involving joint scheduling of wireless access and Time Wavelength Division Multiplexing-Passive Optical Network (TWDM-PON) based fronthaul for COMP joint transmission comprising identifying dependency of wireless access data rate with the number of Front-Haul (FH) optical wavelengths in the TWDM-PON based Cloud-Radio Access Network (C-RAN) model, maintaining synchronization in the FH while transmitting copies of streams through Coordinated Multipoint Reception (COMP) Remote Radio Heads (RRHs) through respective Optical Network Units (ONUs) by necessary changes in the Multi Point Control Protocol (MPCP) and cycle time modification to achieve faithful reconstruction of signals at the ONU including HARQ retransmissions through modifications in Media Access Control (MAC) layer.
