Abstract: A network processing device is configured to receive a configuration message from a host device and forward the configuration message to a server. The configuration message can be configured to request the server assign an Internet Protocol (IP) address to the host device. The network processing device can be configured to send at least one probe message to the host device responsive to receiving the configuration message. The network processing device can be configured to determine whether the host device intends to continue utilizing a previously assigned IP address in addition to the IP address requested by the configuration message based, at least in part, on any responses to the at least one probe message received from the host device.

Abstract: In one embodiment a technique is disclosed for facilitating communication between nodes and a head end of an access network including a head end, at least one shared access upstream channel and at least one downstream channel. A first insertion rate estimate is determined. In at least one embodiment, the first insertion rate estimate may relate to an estimated number of nodes attempting to sign-on to the access network during one or more time interval(s). In at least one embodiment, a frequency of occurrence of initial maintenance opportunities available to a first plurality of network nodes may be dynamically adjusted, for example, using data relating to the first insertion rate estimate. According to one embodiment where the access network corresponds to a cable network, the head end of the cable network may be operable to sign on at least 40,000 cable modems within a time interval of not more than 300 seconds.

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.

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.

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.

Abstract: A hierarchical cable modem clone detection system: A cable modem clone detection system uses a cable modem media access control (MAC) address and physical location information such as information relating to a cable interface, upstream and downstream port numbers, fiber node information, and load balancing group descriptors to determine if a cable modem is a clone.

Abstract: A pharmaceutical composition useful as acetylcholinesterase inhibitors. The present invention relates to pharmaceutical composition comprising the naturally occurring compounds selected from (±) Marmesin, Columbianetin, Dihydroxanthyletin and substituted coumarin derivatives of 7-allyloxy coumarin, 7-benzyloxy coumarin, 7-methoxy coumarin, 7-acetyloxy coumarin, 4-methyl-7-hydroxy coumarin and 4-methyl-7-acetyloxy coumarin. The said compositions posses a high degree of acetylcholinesterase inhibitory (AChE) property.
