摘要： A virtual converged cable access platform (CCAP) system and method for hybrid fiber CATV (HFC) cable networks. The system uses a new type of digital optical fiber node configured to receive optical fiber data packets, and reconstitute the optical data packets into RF waveforms suitable for injection into the system's CATV cable. The system replaces the legacy HFC head end with a simplified “virtual head end”. The system's virtual head end operates using a new type of virtual CCAP controller and virtual CCAP software that in turn controls high performance edge routers. Much of the intelligence of running the HFC cable system is managed by the controller software, while the edge router manages the interface between the CATV portion of the system and outside networks. The system can handle even legacy CATV RF signals by appropriate conversion operations, while reducing power and space needs, and improving operational flexibility.

摘要： System and method to extend the data carrying capacity of a hybrid fiber cable (HFC) network by adding wideband RF signal capability above 1 GHz, and replacing the CATV amplifier devices with an improved type of Coax Domain Amplifier-Repeater (CDAR) device that, in addition to being a smart reconfigurable amplifier and cable signal diagnostic device, also segments the CATV cable portion of the HFC network into a series of smaller domains. The CDAR often alter RF signals from 5-865 MHz, while more freely passing RF signals over 1 GHz. Upstream capability is enhanced because the CDAR intercept 5-42 MHz upstream signals from each domain and convert to 1 GHz+ signals. Downstream capability is also enhanced because the CDAR can take efficiently encoded 1 GHz+ digital data, modulate it, and locally inject into each domain without crosstalk between domains. CDAR can use active cancellation, and active restoration techniques to improve performance.

摘要： Some embodiments provide a method for dynamically creating a service flow for an Ethernet node (EN) in a distributed cable management system that includes a cable headend and several in-the-field ENs for connecting several service nodes to the headend. For a particular device of a particular service node, the method receives a request to create a set of parameters for a service flow that is to be dynamically created. In some embodiments, the received request is in response to a request for a phone call that is to have a quality of service (QoS) guarantee and the service flow is for a PacketCable (PC) connection session. For the service-flow parameter request, the method identifies the EN that connects to the particular service node from a group of several EN that the method manages. The method then forwards a set of authorized dynamic QoS (DQoS) parameters to the identified EN, so that the identified EN can use the forwarded DQoS parameter set to validate a service flow request from the particular device to the EN to create the service flow. The forwarded DQoS parameter set is part of a pre service-flow request that the method sends to the identified EN in some embodiments to direct the identified EN to prepare for a possible service flow request from the particular device.

摘要： A novel method for provisioning network services for a cable system is provided. The method provides a configuration command interpreter/compiler that receives configuration commands of the cable system and generates configuration commands understood by the actual physical devices implementing the cable system. The interpreter transforms the configuration commands of the cable system into the configuration commands of the actual physical devices based on a set of normalized data models describing the cable system. The normalized data models are applicable to the cable system regardless of the actual devices implementing the cable system. The normalized data models are specified using normalized parameters that are generally applicable to different types devices that can be used to implement the cable system.

摘要： A novel method of handling network traffic for cable service flows in a distributed cable system is presented. Such a cable systems use remote distribution nodes in the fields to handle RF communications with cable modems in a distributed fashion. A packet engine is configured to assign a logical interface to each cable service flow in the cable system. Each logical interface in the packet engine is uniquely identifiable by a compound identifier that includes the identifier of the corresponding service flow and the identifier of the remote distribution node. Upon receiving upstream data packet from a particular cable service flow, the remote distribution node applies a set of tags or labels to the data packet identifying the data packet as being from the particular cable service flow. The remote distribution node then forwards the tagged packet toward the packet engine, where the tags/labels are used to direct the packet toward the corresponding logical interface of the particular cable service flow.

摘要： System and method to extend the upstream data capacity of an HFC CATV system by extending a “shadow” optical fiber network deeper into the various CATV cable neighborhoods, with coax fiber terminals (CFT) spaced roughly according to the distribution of CATV active devices such as RF amplifiers. The CFT can intercept local upstream data from various neighborhood sub-regions and transform this upstream data into upstream optical data, thus relieving upstream data congestion in the 5-42 MHz CATV frequency region. The system can produce an order of magnitude improvement in upstream capability, while maintaining high compatibility with legacy HFC equipment. The CFT may exist in multiple embodiments ranging from low-cost “dumb” CFT to sophisticated CFT that can additionally provide GigE to the home (GTTH) service. Methods to maintain good compatibility with legacy CMTS devices, and methods to utilize DOCSIS MAP data for more efficient data transmission are also discussed.
