摘要： The present system uses point-to-point data links between intelligent network elements located in the feeder/distribution network to provide reliable, secure, bi-directional broadband access. Digital signals are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router. The intelligent network elements can be co-located with or replace the standard network elements to take advantage of existing network configurations. A tree-and-branch network architecture is therefore established in which each intelligent network element is assigned a routing ID employed in the point-to-point transmissions while leaving legacy analog signals unimpeded. In this manner, the data links are made over relatively short runs of coax cable, which can provide greater bandwidth than the typical end-to-end feeder/distribution connection between a home and the headend or optical network unit.

摘要： Protection switching of a virtual private network is provided whereby working VPN paths and protection VPN paths are defined. The working VPN path is monitored for increased data traffic and failures, and in response, data is switched from the working VPN path to the protection VPN path. The working VPN path is monitored for a return to proper functioning and normal data conditions, and data is then switched back from the protection VPN path to the working VPN path. Additionally, data capacity is managed through virtual bandwidth classes, and different classes of qualities of service are provided.

摘要： A pipeline scheduler provides a minimum bandwidth guarantee by transporting cells from an input port to an output port in a two-phased approach. Cells that conform to a minimum cell rate (MCR) are selected from queues at the input port and arranged into supercells for transport to the output port, followed by nonconforming cells, to guarantee fairness by using scheduling modules to build the supercells first for conforming cells, and then for nonconforming cells. Reservation vectors are used to permit the same time slot of the next frame to be reserved by a first queue, and the same time slot of the following time frame to be held for reservation by a second queue, to ensure equal time slot access by the first and second queues over successive time frames.
摘要翻译：流水线调度器通过以两阶段方式将单元从输入端口传送到输出端口来提供最小的带宽保证。符合最小单元速率（MCR）的单元从输入端口的队列中选择并排列成超级单元，用于传输到输出端口，随后是不合格单元，以通过使用调度模块首先构建超级单元来保证公平性，然后对于不合格细胞。预留向量用于允许下一帧的相同时隙由第一队列预留，并且后续时间帧的相同时隙被保留以供第二队列预约，以确保等待时隙接入在连续的时间框架上的第一和第二队列。

摘要： A packet communication system of the present invention has first mode, second mode and third mode to apply to input packets. The first mode is a mode that decides priority of the packet by at least one of the address information and the application information, the second mode is a mode that decides priority of the packet by the DS value, the third mode is a mode that decides rewrite the DS value by at least one of the address information and the application information. A control unit of the packet communication system switches a mode to apply an input packet of the first mode, the second mode and the third mode based on the packet header information of the input packet.

摘要： An ATM network traffic shaper is implemented in hardware. The traffic shaper shapes transmit data on one or more virtual circuits (VCs) according to the specified quality of service (QoS) parameters. Thus, the traffic shaper provides for the delivery of associated data cells in accordance with the specified QoS parameters. The traffic shaper is scalable in that the number of supported VCs can be increased with a relatively small increase in the size of the device and associated logic gates. The traffic shaper supports constant bit rate (CBR), variable bit rate (VBR), and unknown bit rate (UBR) service types and generates cell transmit requests with zero cell delay variation (CDVT). The traffic shaper also provides very high resolution in terms of bit rate specification. Varying shaping resolutions are achieved by varying a shaping interval time (SIT) generated by a SIT counter.

摘要： Encapsulating packets includes receiving packets at a queue of an encapsulator. The following operations are repeated until certain criteria are satisfied. A number of packets are accumulated at the queue. A current encapsulation efficiency associated with the accumulated packets is determined. A next encapsulation efficiency associated with the accumulated packets and a predicted next packet is determined. If the current encapsulation efficiency satisfies an encapsulation efficiency threshold and if the current encapsulation efficiency is greater than the next encapsulation efficiency, the accumulated packets are encapsulated. Otherwise, the packets continue to be accumulated at the queue.
