    Abstract: A router includes a classifier that classifies packets assigned to 2n−m classes of service into 2n classes of service that are supported by the router. The classifier then sets the loss priorities of the respective packets to one of m levels. The router uses a modified weighted random early detection scheme that is based on probabilities of discard associated with the 2n+m classes of service to determine whether to retain or discard particular packets. The router uses a single buffer to store packets directed to all of the various output ports. The available storage locations in the buffer are linked to a free queue and a weighted average depth of the free queue, is used to determined whether or not to retain a given packet. The router compares the weighted average depth of the free queue to maximum and minimum thresholds associated with the particular 2n+m class of service to which the packet is assigned. If the weighted average is above the maximum threshold, the packet is retained. If the weighted average is below the minimum threshold, the packet is discarded. If the weighted average is between the two thresholds, a probability of discard that is based on the 2n+m classes of service is calculated and compared to a random value to determine whether or not the packet should be retained. If the probability of discard exceeds the random value, the packet is discarded. The other packets exit various output ports of the router based on weighting factors associated with the 2n classes of service.

    Abstract translation: 路由器包括一个分类器，将分配给2n-m类服务的分组分类为路由器支持的2n类服务。 然后，分类器将各个分组的丢失优先级设置为m个级别中的一个。 路由器使用基于与2n + m类服务相关联的丢弃概率的修改的加权随机早期检测方案来确定是否保留或丢弃特定分组。 路由器使用单个缓冲区来存储指向所有各种输出端口的数据包。 缓冲器中的可用存储位置被链接到空闲队列和空闲队列的加权平均深度，用于确定是否保留给定分组。 路由器将空闲队列的加权平均深度与分配分组的特定2n + m服务等级相关联的最大和最小阈值进行比较。 如果加权平均值高于最大阈值，则保留该数据包。 如果加权平均值低于最小阈值，则丢弃该数据包。 如果加权平均值在两个阈值之间，则计算基于2n + m服务等级的丢弃概率，并将其与随机值进行比较，以确定是否应保留该分组。 如果丢弃的概率超过随机值，则丢弃该数据包。 基于与2n类服务相关联的加权因子，其他分组退出路由器的各种输出端口。

    Abstract: In a control block design methodology, a control block is designed, synthesized, and laid out. The control block includes one or more storage devices, such as flops. The flops include a header which buffers signals common to the flops and a storage cell for storing data. A flop grouping tool is used to merge flops having the same type of header into a flop having storage equivalent to the merged flops but using a single header. Multiple instances of the header may be deleted from the control block.

    Abstract: An internet service node (ISN) enabling the provision of desired service policies to each subscriber. The desired service policies for each subscriber are provided as an input. The desired service policies are translated into processing rules. Each processing rule contains a classifier and associated action. A classifier generally identifies the application data flows to which the action may be applied to provide the desired service policies. The processing rules may be generated dynamically to implement the specified service policies for each subscriber. Each data bit group may be classified to associate with a subscriber and only the processing rules corresponding to the subscriber may be applied to the data bit group to provide the desired services.

    Abstract: A vessel harvesting system that is suitable for harvesting target vessels such as the saphenous vein or radial artery for cardiac artery bypass graft surgery. The system includes a vessel harvesting tool with an elongated cannula and a plurality of surgical instruments therein for separating the target vessels from the surrounding tissue and side branches. The harvesting tool includes a modular handle unit with a base attached to the elongated cannula and a sled that can adapt the base to various types of vessel severing/securing tools, such as tissue welders, bipolar scissors, and bipolar bisectors. The handle unit may be relatively rigid and integrated with the various tool movement controls to facilitate one-handed operation by a user. A severing/securing tool rotation mechanism may be incorporated within the handle and operated by a thumbwheel or other such mechanism. The vessel harvesting system may also provide distal CO2 insufflation for enhanced maintenance of the operating cavity.

    Abstract: A content addressable memory (CAM) having a search field, a mask and an output for each CAM location is used to efficiently determine a processor for processing IP packets, with each IP packet being received as a sequence of cells. IP packets may be assigned to a processor (group) based on an examination of the header data, potentially including IP header and other higher layer protocols headers. The search field of a CAM location is pre-stored with header data, and the bit positions to be searched in the location are specified by using a mask. The output of the location identifies the processor group for executing packets with headers matching the search field, with only the bits specified by the mask being compared. When a first cell of an IP packet is received, the header data is provided as an input to the CAM, and the output identifies the processor (group) for executing the IP packet.
