A system for detecting, monitoring, reporting, and managing congestion in a fabric at the port and fabric levels. The system includes multi-port switches in the fabric with port controllers that collect port traffic statistics. A congestion analysis module in the switch periodically gathers port statistics and processes the statistics to identify backpressure congestion, resource limited congestion, and over-subscription congestion at the ports. A port activity database is maintained at the switch with an entry for each port and contains counters for the types of congestion. The counters for ports that are identified as congested are incremented to reflect the detected congestion. The system includes a management platform that periodically requests copies of the port congestion data from the switches in the fabric. The switch data is aggregated to determine fabric congestion including the congestion level and type for each port and congestion sources.

A communication system for distributing information via a network to one or more subscribers includes a multi-port switch, one or more radio frequency (RF) modems coupled to respective ports of the switch, a combiner and a transmitter. The switch forwards source information to the RF modems based on address information.

Each channel is assigned to one or more subscribers, and each subscriber is allocated unshared bandwidth. Each channel may be further divided into unshared bandwidth increments, so that multiple subscribers may share a single channel. The combiner combines modulated information from each RF modem into a combined signal and the transmitter transmits the combined signal to the subscribers via the network. An HFC network including a distribution point and one or more optical nodes is contemplated, each optical node serving a particular geographic area via a corresponding coaxial cable. Each subscriber destination includes a gateway device or the like that is tuned to a corresponding channel to retrieve source information from that channel, and to deliver the information to one or more local subscriber devices. The gateway further includes converters, a modulator and an up converter to receive and transmit subscriber information upstream to the distribution point. The gateways and an address resolution server enforce point to point communications. A bandwidth manager allocates bandwidth and monitors bandwidth usage.
