摘要： A pipelined out-of-order process and system for handling data packets in a network device. The process and system are scalable to support throughput in excess of 10 Gbps. The system includes a set of processing cores that offload the table look up operations and similar operations from the central processing unit. The central processing unit receives the requisite data needed for performing forwarding, routing, NAT, firewall maintenance and similar operation on data packets from the set of processing cores.

摘要： An internet service node (ISN) enabling the provision of desired service policies to each subscriber. The ISN may contain multiple processor groups, with each subscriber being assigned to a processor group. The assigned processor group may be configured with the processing rules, which provide the service policies desired, by a subscriber. A port may determine the specific processor group to which received data is to be forwarded. A content addressable memory with masks for individual locations may be implemented to quickly determines the processor group to which received data is to be assigned to. Due to the features of the present invention, an ISN may be able to serve a large number of subscribers efficiently. The ISN may be used at the edge of an access network.

摘要： A device for use in a computer system, particularly a personal computer (PC) which provides compatibility for a proposed ISA plug and play (PNP) standard. The device of the present invention is also backward compatible with non-PNP (legacy) PCs. Upon power-up, a device may initialize using default traditional or specification (ISA) values for I/O address, IRQ and DMA channels. If PNP activity by the host PC is detected by the device, the device is disabled, and awaits activation and I/O address, IRQ and DMA channel assignments from a host PC. If no PNP activity by a host PC is detected, the device continues to operate using default traditional or specification (ISA) I/O address, IRQ and DMA channels. The device of the present invention may be installed in PNP or legacy type PCs without reconfiguring hardware (e.g., DIP switches, jumpers or the like) in the device or installing new firmware, operating system, or applications software in a host PC.
