IPTV targeted messages

A network device configured to provide targeted messages to a subscriber of Internet Protocol Television (IPTV) when a request of the subscriber to access an IPTV channel is denied, the network device comprising:

• a non-transitory machine readable storage medium having stored therein a group management protocol module, an IPTV Connection Admission and Control (CAC) module, a multicast routing protocol module, and a multicast forwarding module;
• and
• a network processor communicatively coupled to the non-transitory machine readable storage medium, the network processor configured to execute the group management protocol module, the IPTV CAC module, the multicast routing protocol module, and the multicast forwarding module, wherein the group management protocol module is configured to receive the request of the subscriber from a customer premise equipment (CPE) to access a first multicast stream, where the first multicast stream is a multicast stream for an IPTV channel, the IPTV CAC module configured to check whether the request to access the first multicast stream is denied, determine a reason for denial in response to determining that the request is denied, and determine a second multicast stream that corresponds to the reason for denial, the multicast routing protocol module configured to send a join message to a multicast source to receive the second multicast stream, the multicast forwarding module configured to forward the second multicast stream to the CPE.

A non-transitory machine readable storage medium having stored therein instructions to be executed by a network device to provide targeted messages to a subscriber of Internet Protocol Television (IPTV) when a request of the subscriber to access an IPTV channel is denied, the instructions when executed by the network device cause the network device to perform a set of operations comprising:

• receiving the request of the subscriber from a customer premise equipment (CPE) to access a first multicast stream, wherein the first multicast stream is a multicast stream for an IPTV channel;
• checking whether the request to access the first multicast stream is denied;
• determining a reason for denial in response to determining that the request is denied;
• determining a second multicast stream that corresponds to the reason for denial;
• sending a join message to a multicast source to receive the second multicast stream;
• and
• forwarding the second multicast stream to the CPE.

A computing device implementing a plurality of virtual machines for implementing network function virtualization (NFV), wherein a virtual machine from the plurality of virtual machines is configured to provide targeted messages to a subscriber of Internet Protocol Television (IPTV) when a request of the subscriber to access an IPTV channel is denied, the computing device comprising:

• a storage medium having stored therein a group management protocol module, an IPTV Connection Admission and Control (CAC) module, a multicast routing protocol module, and a multicast forwarding module;
• and
• a processor communicatively coupled to the storage medium, the processor configured to execute the virtual machine, where the virtual machine is configured to implement the group management protocol module, the IPTV CAC module, the multicast routing protocol module, and the multicast forwarding module, wherein the group management protocol module is configured to receive the request of the subscriber from a customer premise equipment (CPE) to access a first multicast stream, where the first multicast stream is a multicast stream for an IPTV channel, the IPTV CAC module configured to check whether the request to access the first multicast stream is denied, determine a reason for denial in response to determining that the request is denied, and determine a second multicast stream that corresponds to the reason for denial, the multicast routing protocol module configured to send a join message to a multicast source to receive the second multicast stream, the multicast forwarding module configured to forward the second multicast stream to the CPE.
