摘要： A network device has a network interface to allow the device to send and receive traffic across a network. The device also has a cable connection to allow the device to exchange data with at least one cable modem and a processor to associate a cable interface and cable service identifier with a cable modem; receive a packet from the cable modem; and insert a layer 2 network identifier, the identifier comprising two service provider VLAN (SP-VLAN) tags, into the packet. The processor in the network device identifies a virtual trunk interface based on the outer SP-VLAN tag and identifies the virtual private network based on the inner SP-VLAN tag.

摘要： Methods and apparatus are disclosed for offering broadcast IPTV solutions over cable (HFC networks). Rather than bypass the CMTS, a reduced number of downstream ports are utilized for video streams. Each input video stream is streamed to a multicast group address. In one embodiment, several RF channels are configured so that they are RF spanned across all the Fibernodes in the CMTS service area. In an embodiment, an STB sends a service request for a desired video stream using an IGMP request, and the CMTS responds by issuing a DBC request to tune the corresponding CM to the RF channel that is carrying the requested stream. Preferably, the CMTS ports that carry the static multicast streams are RF spanned across all the Fibernodes, or a selected subset.

摘要： A network device has a network interface to allow the device to send and receive traffic across a network. The device also has a cable connection to allow the device to exchange data with at least one other device across a cable network. The device has a processor to receive traffic having a network identifier through the network interface and determine if the network identifier is associated with a virtual private network. If the network identifier is associated with a virtual private network, the device then routes the traffic to an appropriate receiving entity through the cable connection if the network identifier is associated with a local are network.

摘要： A wideband cable network system includes multiple wideband cable modems and a Wideband Cable Modem Termination System (WCMTS). The WCMTS operates a Media Access Control (MAC) layer that communicates with the cable modems over multiple different downstream Radio Frequency (RF) channels and upstream RF channels. A wideband failure analytic manager tracks fault indicators associated with the MAC layer communications. Separate failure analytics are then generated, indexed, and correlated for different cable modems and different upstream or downstream channels.
