摘要： Use of a hash operation based on selected information in the packet to select one of a set of enable vectors. The selected enable vector is then effectively ANDed with the link expansion vector to select the actual links to be used. The enable vectors vary by selecting a different link in the LAG port for each enable vector. Thus the hash is used to vary the link of the LAG port used to transmit the packet for that multicast packet.

摘要： A mechanism for identifying long-lived large flows in a communication network is disclosed in which packets transmitted through ports of a switching device or router are continuously examined. As new flows are recognized, their flow definition information is processed through a hashing table that uses a predetermined number of hash stages each having a pre-selected number of hash buckets. Each hash bucket has a counter that is incremented each time flow definition information ends up in the bucket. At the same time as counters are incremented, they are compared against a threshold number. If the bucket counters for all the hash stages exceed this threshold number, the flow is identified as a long-lived large flow and stored as such in a flow table.

摘要： Packets or data units and their related credit returns each include an assigned phase value. When a credit test is desired, the phase value of outgoing data units is changed, for example from 0 to 1, and a new counter is set to a value of the outstanding credits having the original phase value. With each original phase credit received, the counter value is decremented. When a credit having the new phase value is received, the counter value indicates the amount of any credit error and appropriate corrections may be made.

摘要翻译： 使用基于分组中的所选信息的哈希操作来选择一组启用向量中的一个。 然后，所选择的使能向量与链路扩展向量有效地进行AND，以选择要使用的实际链路。 启用向量通过为每个启用向量选择LAG端口中的不同链路而有所不同。 因此，该散列用于改变用于传输该组播数据包的数据包的LAG端口的链路。
