摘要： A digital clock frequency multiplier (100) for increasing an input frequency of an input clock signal includes a generator (102) that receives the input clock signal and a high frequency digital signal. The generator (102) divides a count (Nhf) of a number of cycles of the high frequency digital signal in one period of the input clock signal by a predetermined multiplication factor (MF) for generating an output clock signal. The output clock signal has a predetermined output frequency.

摘要： A band-gap reference circuit for generation of voltages and currents independent of process, voltage, and temperature includes three inversely proportional to absolute temperature (IPTAT) current generators. The IPTAT current generators generate three currents that are added to generate a current independent of the absolute temperature. The generated current is passed through a switched capacitor resistor to generate the band-gap reference voltage across the switched capacitor resistor.

摘要： A network controls provision of access functionality by an access node to provide a network service to a subscriber device. For example, the network device may control the queuing and forwarding of packets by the access node to facilitate packet transmission according to, for example, a Quality of Service class. The network device may send control messages to the access node to dynamically configure a control object stored by the access node, such as a Quality of Service profile. The network device may be a router, and the access node may be a base station that wireless communicates with a subscriber device, e.g., a cellular phone. The access node may then delivery the packets in accordance with the dynamically configured control object.

摘要： A network device may include logic to establish an IP session, establish a BFD session within the established IP session, transmit BFD packets within the established BFD session, and determine that the established IP session is active based upon reception of the BFD packets. In another embodiment, the logic may also determine that an IP session is active using an inactivity timer that may also trigger transmission of BFD packets.

摘要： In general, techniques are described for automatically releasing network resources reserved for use by network devices within a network. In particular, a network device, such as a router, may include an interface card that receives a first and a second message from respective first and second client devices requesting reservation of network resources. The first message may include a first identifier, while the second message may include a second identifier. Both messages however may also include the same additional context information that identifies the same context in which the first client device operates. The router may include a control unit that determines whether the additional context information included within the first and second messages is the same. Based on a determination that this information is the same, the control unit may automatically release resources reserved for use by the first client device within the network.

摘要： Methods and systems consistent with the present invention provide a way to provide optimal delivery of multicast content by retail ISPs in a wholesale aggregation network environment. A broadband network gateway dynamically informs an access node of a mapping between a multicast domain corresponding to the retail service provider, allowing the gateway to send multicast data to the access node for replication to subscribers instead of replicating the multicast data at the gateway. The gateway dynamically informs the access node of the mapping using a standardized access node control protocol. The gateway can also dynamically instruct the access node to update or delete the mapping.

摘要： Methods and systems consistent with the present invention provide a dynamic mechanism to support wholesale access for broadband subscribers. This mechanism involves dynamically discovering a retail ISP for a subscriber, and dynamically cross-connecting a subscriber's connection to a logical connection corresponding to a retail ISP, and is equally applicable to static, PPP and DHCP-based subscribers. Furthermore, dynamic steering of subscribers can be performed at layer 2 or layer 3 of the OSI model.
摘要翻译：与本发明一致的方法和系统提供了支持宽带用户的批发接入的动态机制。该机制涉及动态地发现用户的零售ISP，并将用户的连接动态地交换到对应于零售ISP的逻辑连接，并且同样适用于静态，基于PPP和基于DHCP的用户。此外，可以在OSI模型的层2或层3上执行用户的动态转向。
