  • Patent number: 7693180
    Abstract: Disclosed are methods and apparatus for translating data within a cable network between a first voice-over-IP (VOIP) protocol used by a user agent and a second VOIP protocol used by a call management server, or other type of call receiver. In one embodiment, data from an SIP (Session Initiation Protocol) user agent is translated for an NCS (Network Call Signaling) call management server. In one implementation, translation mechanisms are provided within the customer premises equipment in which the respective user agent is also configured.

  • Publication number: 20090125957
    Abstract: A CMTS or other data aggregation component having a DHCPv6 relay agent extracts a Media Access Control (MAC) address of an end device from a data packet received from an end device. A DHCPv6 data frame is created for transmission to a DHCPv6 server. The MAC address may be inserted into a specific option of the DHCPv6 data frame, where data in the option may not be processed by the server and are echoed back to the aggregation component or CMTS. The DHCPv6 data frame is transmitted to the DHCPv6 server. The component receives a response message from the server that may contain the MAC address or similar client hardware address as it was sent to the server by the network component. The network component may determine an outgoing port interface from which the response message should be sent, utilizing the MAC address and an interface bundling table. In this manner, interface bundling may be enabled.

  • Publication number: 20080298277
    Abstract: A network device is to receive traffic including neighbor discovery messages from requesting customer devices, and can detect the neighbor discovery messages within the traffic according to a distributed inspection scheme that includes the network device and a remote component. The network device is to then examine the neighbor discovery messages to determine if the neighbor discovery message should be forwarded to other of the customer devices, and respond to the requesting customer devices.
