  • Method and apparatus for dynamically allocating upstream bandwidth in passive optical networks
    Patent number: 8964540
    Abstract: One embodiment of the present invention provides a system that facilitates dynamic allocation of upstream bandwidth in a passive optical network which includes a central node and at least one remote node. Each remote node is coupled to at least one logical entity, which corresponds to a device or a user, that transmits upstream data to the central node and receives downstream data from the central node. The central node is coupled to an external network outside of the passive optical network through a shared out-going uplink.
    Type: Grant
    Filed: October 26, 2012
    Date of Patent: February 24, 2015
    Assignee: Broadcom Corporation

  • Method and apparatus for dynamically allocating upstream bandwidth in passive optical networks
    Patent number: 7436765
    Abstract: One embodiment of the present invention provides a system that facilitates dynamic allocation of upstream bandwidth in a passive optical network which includes a central node and at least one remote node. Each remote node is coupled to at least one logical entity and includes a number of queues, each of which is associated with a logical entity and stores upstream data from the logical entity. The central node is coupled to an external network through a shared out-going uplink. During operation, the system receives a request from a remote node for a grant to transmit upstream data from a logical entity, wherein the request reports the state of a queue associated with a logical entity; wherein the size of the data to be transmitted does not exceed a transmission threshold assigned to that logical entity, and wherein a logical entity may not request more than what is allowed by the corresponding transmission threshold.
