摘要:
Apparatus and methods for communication system-level communication link bonding are disclosed. Multiple communication links provided by transceivers in communication link termination modules are configured as a bonding group to support an aggregate group communication traffic rate on another communication link. Through an internal communication mechanism in communication equipment, communication traffic received on the other communication link is distributed among those of the communication link termination modules which include transceivers for transferring communication traffic on the communication links in the bonding group. The bonding module also receives, from communication link termination modules, communication traffic to be sent on the other communication link.

Apparatus and methods for providing remote control and control redundancy for distributed communication equipment are disclosed. An expansion system in a distributed communication equipment architecture is controlled by a controller in a host system. Control information is exchanged between the host system controller and an expansion system in communication signals that are processed by one or more communication modules such as line termination cards in the expansion system. Communication signals are transferred to the communication module(s) through an expansion system control device, and control information is then transferred back to the control device. Control information may also be transferred from the expansion system control device to the host system through the communication module(s). This simplifies the design and lowers the cost of the control device, which does not process received signals. Control redundancy is provided in some embodiments by implementing multiple communication modules and corresponding communication links.
摘要:
The present invention relates to a switching unit with a low-latency flow control. Queuing parameters of ingress queues, wherein the incoming traffic is backlogged, are measured to detect a short term traffic increase. An additional bandwidth is then negotiated to accommodate this unexpected additional amount of traffic, provided that the corresponding input and output termination modules still dispose of available bandwidth, and disregarding temporarily fairness. This additional bandwidth allows this unexpected additional amount of traffic to be drained from the ingress queue as soon as possible, without waiting for the next system bandwidth fair re-distribution, thereby improving the traffic latency through the switching unit.
