A novel cable gateway system and architecture incorporating a hybrid digital video transceiver. The digital cable system architecture combines reception of legacy video such as MPEG-TS based DVB-C streams with that of original IP video over DOCSIS channels. The system comprises a hybrid DVB / IP cable gateway STB capable of receiving both legacy DVB-C video and original IP video streams. The cable gateway device performs the front-end functionality (including QAM receiver, tuner and broadband connection) while the back-end functionality of video decoding and display is performed by one or more standard IP-STBs connected to the cable gateway device over a network (e.g., home LAN). Legacy MPEG-TS based DVB-C video is captured and encapsulated into packets for distribution over the network to the IP-STBs. The cable gateway distributes the original IP video received over the CATV source and the encapsulated legacy video as video over IP packets over the network.

QoS is built into a peer network within existing Internet infrastructure itself lacking QoS, by enabling a network peer to continuously discern the network's ability to deliver to that peer a particular Content Object (distributed in groups of component Packages among neighboring VOD peers) within predetermined times. Content Objects are divided into groups of component Packages and distributed to Clusters of neighboring network peers, enhancing QoS upon subsequent retrieval. Tracking Files (lists of network peers storing Package groups) and Tracking Indexes (lists of network peers storing Tracking Files) are generated to facilitate “on demand” Content Objects retrieval. Dynamically monitoring network traffic (including VOD functionality, bandwidth and reliability) creates “distributed closed-loop feedback,” and in response, attributes of individual network peers (e.g., Trust Level and membership within a particular Cluster) are modified, and “content balancing” functions performed (e.g., redistribution of Package groups among network peers) enables maintaining high QoS.

Methods of creating a secure channel over which credit card personalization data can be transmitted over the air (OTA) are provided. In particular, Generic Authentication Architecture (GAA) may be used to establish a secure communication channel between the user equipment (UE) and a personalization application server or bureau acting as a network application function (NAF) server. An user equipment, personalization application service (e.g., a NAF server), a system embodying a personalization application server and an user equipment, and a computer program product are also provided for creating a secure channel, such as via GAA, over which credit card personalization data can be transmitted OTA.

In an MPLS network, multicast, broadcast and address learning belonging to the layer 2 functions are realized. An ingress router comprises a frame receiving unit, a determining unit, a first frame transmitting unit, a physical address table for multicast, a label switching unit, a tunnel label table, a VCID giving unit, a L2 header creating unit and a second frame transmitting unit. The load on the network is suppressed, the band is efficiently used, and wasteful frame duplication and frame forwarding between edge routers are avoided.

A two-way cable network offering high-speed broadband communications delivered via virtual private networks over a multi-channel shared media system. Bi-directional transmission of packet to ATM cell based communications is established between a head end communication controller and a number of subscriber terminal units, whereby individual cells are prioritized and routed according to a virtual connection. Virtual connections are organized to support multiple virtual private networks in a shared media CATV system. The virtual private network to which a particular STU belongs is user selectable and has the flexibility of handling multi up / downstream channels with different MAC domains. The present invention can also handle non-ATM MAC domains via the same common ATM switch. To overcome the limited number of addresses inherent to common ATM switches, a mapping / remapping function is implemented in the port cards. Furthermore, downstream as well as upstream traffic are filtered at each STU. In one embodiment, information pertaining to downstream traffic is used to implement predictive scheduling in order to improve the timing associated with the request / grant cycle. In another embodiment, a user has the ability to select a quality of service that best suits the needs of the current application. In a further embodiment, the scheduling function is associated with each of the receivers in order to provide improved scalability.
