摘要： A method and system for transmitting packets in a packet switching network. Packets received by a packet processor may be prioritized based on the urgency to process them. Packets that are urgent to be processed may be referred to as real-time packets. Packets that are not urgent to be processed may be referred to as non-real-time packets. Real-time packets have a higher priority to be processed than non-real-time packets. A real-time packet may either be discarded or transmitted into a real-time queue based upon its value priority, the minimum and maximum rates for that value priority and the current real-time queue congestion conditions. A non-real-time packet may either be discarded or transmitted into a non-real-time queue based upon its value priority, the minimum and maximum rates for that value priority and the current real-time and non-real-time queue congestion conditions.

摘要： A method for dynamically adjusting the flow rate of a plurality of logical pipes that share a common output queue. In accordance with the method of the present invention, a minimum flow rate and a maximum flow rate are set for each of the pipes. Next a determination is made of whether or not excess queue bandwidth exists in accordance with the output flow rate of the shared queue. The determination of whether or not excess bandwidth exists comprises comparing the output flow rate of the shared queue with a pre-determined threshold queue output value. An instantaneous excess bandwidth signal has a value of 1 if there is excess bandwidth and is otherwise 0 if there is no excess bandwidth. In an alternate embodiment, the instantaneous excess bandwidth signal for a particular pipe is logically ANDed with one or more additional excess bandwidth signals to form a composite instantaneous excess bandwidth signal. In response to the existence of excess queue bandwidth, a flow rate of a pipe is linearly increased while in response to a lack of excess queue bandwidth, the flow rate of the pipe is exponentially decreased.
摘要翻译：一种用于动态调整共享公共输出队列的多个逻辑管道的流量的方法。根据本发明的方法，为每个管设定最小流量和最大流量。接下来，根据共享队列的输出流量确定是否存在过量队列带宽。确定是否存在超量带宽包括将共享队列的输出流量与预定阈值队列输出值进行比较。如果存在过多的带宽，则瞬时过量带宽信号的值为1，如果没有超额带宽，则为0。在替代实施例中，用于特定管道的瞬时过量带宽信号与一个或多个附加过量带宽信号进行逻辑“与”，以形成复合瞬时过量带宽信号。响应于存在多余的队列带宽，管道的流量线性增加，同时响应于缺少多余的队列带宽，管道的流量呈指数下降。

摘要： A method and system for controlling a plurality of pipes in a computer network is disclosed. The computer network includes at least one processor for a switch. The at least one processor has a queue. The plurality of pipes utilizes the queue for transmitting traffic through the switch. The method and system include allowing a minimum flow and a maximum flow to be set for each of the plurality of pipes and determining if excess bandwidth exists for the queue. The method and system also include linearly increasing a flow for a pipe of the plurality of pipes based on the minimum flow or the maximum flow if excess bandwidth exists and if the flow for the pipe of the plurality of pipes is less than the maximum flow for the pipe. The method and system also include exponentially decreasing the flow for the pipe of the plurality of pipes based on the minimum flow or the maximum flow if excess bandwidth does not exist and the flow is greater than the minimum flow for the pipe. Thus, the traffic through the queue is stable.

摘要： A controllable mechanism for by-passing Layer 4 (L4) classification is based on the insertion into a set of MAC rules in SA MAC lookup means a set of Layer 4 (L4) Skip Classification Flags. Routing is accomplished by selecting which rule to apply to the packet and reading the state of the corresponding L4 Skip Classification Flag. In response to a first state of said corresponding L4 Skip Classification Flag, performing an L4 classification followed by a routing of the data packet. In response to a second state of said corresponding L4 Skip Classification Flag, reading the state of a Global Classification Flag. In response to a first state of said Global Classification Flag, performing an L4 classification followed by a routing of said data packet. In response to a second state of said Global Classification Flag performing a routing of the data packet. The L4 Skip option change does not use the option change of reading the L4 Skip Classification Flag from the port table, whereas the second embodiment uses this option. The third and fourth embodiments are similar to the first and second embodiments but with the. addition of inserting into a set of Layer 3 (L3) rules in L3 lookup means a set of Layer 4 (L4) Classification Required Flags. The third embodiment does not use the option of reading the L4 Skip Classification Flag from the port table, whereas the fourth embodiment uses this option.
