    摘要: A method and system to dynamically manager power in a communication system are provided herein. The method comprises the steps of monitoring a transmit data queue once every first pre-determined period of time and determining whether the transmit data queue is empty for a pre-determined number of times. The method further includes the step of generating a transition state signal to stop de-queuing of data from the transmit queue if the transmit data queue is empty for the pre-determined number of times and selectively operating portions of a Physical Layer (PHY) that are used for functions other than transmitting and receiving an idle signal in a low power mode.

    摘要: Priority-aware hierarchical communication traffic scheduling methods and apparatus are disclosed. Communication traffic is scheduled by schedulers. Each scheduler supports a multiple priority scheduling function to schedule communication traffic having any of multiple priorities. The communication traffic scheduled by the schedulers is further scheduled based on the priorities of the communication traffic scheduled by each of the schedulers. Traffic shaping may also be integrated into a hierarchical scheduler. The priority-aware further scheduling and the optional shaping may be implemented, for example, using multiple Active lists, one per traffic priority, and a Pending list to which a scheduler can be added if it has communication traffic to schedule but is not allowed to schedule that traffic due to the shaping.

    摘要: A repeater, useable for connecting switches in a data communication network, is provided in a distributed and/or modular fashion. The repeater includes a plurality of separate and distinct components or modules connected to or at least partially housed in, the various switches which the repeater modules couple. The distributed and/or modular repeater facilitates accommodating various switching or repeater needs as a network grows or contracts. A light pipe, preferably integral with a module case, conveys indicator lights to a position visible when viewing a switch front panel. A heat spreader unit receives and/or conveys heat and/or protects against undue EMI. A collision-handling state machine transmits modified collision fragments so as to avoid reduction in interpacket gaps, e.g. by downstream repeater modules.
