摘要： Hybrid fiber/coax networks employ the existing cable plant used for cable TV and transmit data signals in a frequency bandwidth above that which is used for cable TV. As this cable plant was deployed in a tree and branch topology, data transmissions may be susceptible to noise, variable transmission loss and frequency dispersion, particularly in the upstream direction. Further, due to the tree and branch topology, homes at the far end of the network experience much greater loss than do the homes that are near to the headend/ONU. The present system, which uses point-to-point data links between intelligent network elements located in the feeder/distribution network to provide reliable, secure, bi-directional broadband access. Digital signals, or messages, are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router. Messages indicative of an end user routing ID (RID) are identified and the information extracted for user with successive messages. In this manner, the data links are made over relatively short runs of coax cable, which can provide greater bandwidth than the typical end-to-end feeder/distribution connection between a home and the headend or optical network unit.

摘要： In an application level multicast (ALM), multiple flows of data packets containing shared material are destined for different devices. A packet compression device is used to compress the data packets to reduce traffic load. This compression device includes a cache for recording the payloads of selected data packets which currently are not of record in the cache. If it is determined that the cache has therein a record of an identical version of the payload of a data packet, the compression device releases a compressed version of the data packet which includes a representation of the payload in lieu of the actual payload.

Digital signals are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router. The intelligent network elements can be co-located with or replace the standard network elements to take advantage of existing network configurations. The standard network elements can be selectively replaced by the intelligent network elements in an incremental approach. A method of discovering the network topology includes sending a message from one of the network elements on a transmission path to a topology server, the message including information identifying the one network element. At each intermediate network element in the transmission path, information identifying each intermediate network element is appended to the message. In this manner, the data links are made over relatively short runs of coax cable, which can provide greater bandwidth than the typical end-to-end feeder/distribution connection between a home and the headend or optical network unit.

The intelligent network elements can be co-located with or replace the standard network elements to take advantage of existing network configurations. The standard network elements can be selectively replaced by the intelligent network elements in an incremental approach. Packet handling at a network element includes receiving flows of packets from one or more devices coupled to the network element. A service instance associated with each packet in the packet flows is identified and a quality of service (QoS) class for each packet from the corresponding service instance is determined. The packet flow associated with each service instance is regulated according to corresponding policing criteria. In this manner, the data links are made over relatively short runs of coax cable, which can provide greater bandwidth than the typical end-to-end feeder/distribution connection between a home and the headend or optical network unit.

A tree-and-branch network architecture is therefore established in which each intelligent network element is assigned a routing ID employed in the point-to-point transmissions while leaving legacy analog signals unimpeded.
