摘要： Described embodiments provide a lookup engine that receives lookup requests including a requested key and a speculative add requestor. Iteratively, for each one of the lookup requests, the lookup engine searches each entry of a lookup table for an entry having a key matching the requested key of the lookup request. If the lookup table does not include an entry having a key matching the requested key, the lookup engine sends a miss indication corresponding to the lookup request to the control processor. If the speculative add requestor is set, the lookup engine speculatively adds the requested key to a free entry in the lookup table. Speculatively added keys are searchable in the lookup table for subsequent lookup requests to maintain coherency of the lookup table without creating duplicate key entries, comparing missed keys with each other or stalling the lookup engine to insert missed keys.
摘要翻译：描述的实施例提供了一种查找引擎，其接收包括所请求的密钥和推测添加请求者的查找请求。迭代地，对于每个查找请求，查找引擎搜索查找表的每个条目，以获得具有与查找请求的请求密钥匹配的密钥的条目。如果查找表不包括具有与所请求的密钥匹配的密钥的条目，则查找引擎向控制处理器发送对应于查找请求的未命中指示。如果设置了推测性添加请求者，则查找引擎推测性地将请求的密钥添加到查找表中的空闲条目。在查找表中可以搜索用于后续查找请求的推测加密密钥，以维护查找表的一致性，而不创建重复密钥条目，将错过的密钥彼此进行比较，或者阻止查找引擎插入错过的密钥。

摘要： A system and method to multicast guaranteed and best-effort traffic in a communications network are disclosed. According to one embodiment, incoming traffic is separated into unicast traffic and multicast traffic. Each root cell of the multicast traffic is classified based on multiple corresponding classes of service. Each root cell is then stored into a root cell buffer of multiple root cell buffers within an egress memory, each root cell buffer being associated with a corresponding class of service. According to one embodiment, each root cell is retrieved from the corresponding root cell buffer within the egress memory according to the associated class of service. Each root cell is then stored in a corresponding replication queue of multiple replication queues based on its associated class of service, with predetermined replication parameters assigned to each replication queue. Each root cell is subsequently replicated according to one or more associated replication parameters to obtain multiple leaf cells for each replicated root cell. According to one embodiment, the unicast traffic is multiplexed with the replicated leaf cells of the multicast traffic to obtain egress arrival cells. Each egress arrival cell is then stored hierarchically into a queuing buffer of multiple queuing buffers within a queuing memory according to queuing parameters corresponding to each egress arrival cell.

摘要： A system and method for efficient packetization of cells transmitted over a packet network are described. Multiple virtual connections are received, each virtual connection carrying multiple cells. One or more cells of the cells carried by each virtual connection are stored for a predetermined time period. A cell counter of the stored cells is modified to indicate a number of the stored cells. Finally, a packet containing the stored cells is formed, the packet to be transmitted to a destination node over a network.
