A Point to Multipoint (PMP) multi-hop relay network includes a base station, one or more relay stations and one or more subscriber stations. Active service flows in a PMP multi-hop relay network have a 16-bit connection identifier (CID). A CID defines the connection that a packet is servicing. Before traffic can be transmitted, the path through the network, and the association of CIDs with respective hops needs to be established. The CID mapping relationship from the ingress air link to the egress air link at each relay station is first set up, which is then followed by a traffic phase where the CID mapping relationship is used to route traffic from a base station to a subscriber station.

A method and apparatus are disclosed for per-service flow protection and restoration of data in one or more packet networks. The disclosed protection and restoration techniques allow traffic to be prioritized and protected from the aggregate level down to a micro-flow level. Thus, protection can be limited to those services that are fault sensitive. Protected data is duplicated over a primary path and one or more backup data paths. Following a link failure, protected data can be quickly and efficiently restored without significant service interruption. A received packet is classified at each end point based on information in a header portion of the packet, using one or more rules that determine whether the received packet should be protected. At an ingress node, if the packet classification determines that the received packet should be protected, then the received packet is transmitted on at least two paths. At an egress node, if the packet classification determines that the received packet is protected, then multiple versions of the received packet are expected and only one version of the received packet is transmitted.

A long-term usage profile and a congestion state metric are used to determine QoS treatment to apply to packets corresponding to a given network user. A user's historical long-term use, measured over one or more periods of time, is used to generate a profile that is compared to one or more predetermined usage threshold level(s). If the usage profile, either singular or composite corresponding to whether one or more than one measurement is used respectively, exceeds the threshold(s), QoS treatment is applied to service flow bytes according to the comparison results during times of network channel congestion. Congestion metrics are determined based on a count of the number of bytes dropped during a congestion measurement window. Either the count itself or the count rate of change combined with the count are compared to a congestion threshold. If the measured / derived values exceed a congestion threshold, the channel is deemed congested.

A communications system in which event based charging is implemented and in which service flows between end user equipments and application servers are filtered for charging purposes by a traffic plane function (TPF). The TPF identifies a service flow between an end user equipment and an application server and implements event based charging by sending a message to an Event Owner for the service flow requesting notification of Events associated with the service flow.

A system and method for delivering and charging for data services over a netword system. A hardware device called "network access controller" (NAC) can be configured by a management system with information regarding data services available on a per-user, per-customer, or per-service basis. The access controller is able to read all data packets coming into the network and figure out whether they indicate the start of any premium service session like video on demand or whether they are from a premium user who needs special treatment. The access controller is able to process incoming data packets without leading to any degradation in performance or throughput. Once it detects the start of a specific type of data service session, then the access controller signals to the management system that this data service flow has started and supplies additional information extracted from the incoming data packet. Using this information and additional information on the capacity of the transport network and server resources, the number of service sessions already active and availability of credit, such as billing authorization information from a billing system, the management system can determine whether to allow the start of this service or not. The management system communicates this decision to the access controller and alters the Access Control Lists (ACLs) in traffic shapers appropriately. If the data service request is admitted into the network, then additional bandwidth is opened in The traffic shapers so that the end user receives the appropriate quality level for the service. If the service request is denied access, then the end user will not be able to gain access to the premium service.

A method of using DOCSIS 1.1 features to allow the addition of ISPs and QOS levels to a single cable modem without having to modify the CMTS is described in the various figures. Instead of using the SID of a data packet to determine the VPN tag of a data packet (DOCSIS 1.0), a service flow is used to identify the appropriate tag. This is done using the DOCSIS 1.1 configuration file. By doing so, the need for creating additional sub-interfaces in the cable modem interface does not arise. Instead, the configuration is modified at the provisioning server, i.e., the DHCP / TFTP server.
