摘要:
The present disclosure is directed to a method and apparatus for maintaining sub-queues at an ONU and for maintaining a count of an amount of data stored in each sub-queue or a count of an amount of data associated with elements stored in each sub-queue. The sub-queues represent partitions in a first in, first out (FIFO) queue used by the ONU to buffer packets, or elements that are associated with packets, to be sent upstream. The sub-queues are coupled in series such that the output of a first sub-queue feeds the input of a second sub-queue, the output of the second sub-queue feeds the input of a third sub-queue, etc. Each sub-queue has a defined threshold that sets a maximum amount of packet data it can buffer or the elements in which it buffers can be associated with.
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.

A method and apparatus for extending multipoint control protocols to mixed media 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 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:
Embodiments of a scalable optical network unit (ONU) architecture for multi-dwelling units (MDUs) that has a low initial cost (or first port cost) and a low maintenance cost are provided herein. The ONU architecture is scalable in that a growing number of end users can share a single drop fiber that couples the ONU to a passive optical network. The ONU architecture utilizes a multiplexer module to allow the ONU to be daisy chained with one or more additional ONUs.
