摘要： An end system cell flow regulator includes a congestion state determiner (208), a data source (202), a cell scheduler (206), and a leaky bucket monitor (204). The congestion state determiner typically decides congestion state based on feedback information and a timer. The data source typically further includes a cell generator, a cell buffer, a cell flow switch and a cell buffer state determiner. The cell scheduler further includes a DCR, Dynamic Cell Rate, determiner and a cell rate determiner, wherein the cell scheduler decides the next cell time for transmission based on the cell buffer state, congestion state and leaky bucket state. The cell rate determiner determines if the cell rate is set to DOR or PCR, Peak Cell Rate, based on the leaky bucket and cell buffer states. The DCR determiner establishes the DCR rate based on congestion state and cell buffer state.

摘要： A queueing and dequeueing mechanism for use in an integrated fast packet network, wherein fast packets from differing traffic types are multiplexed with one another through use of a weighted round-robin bandwidth allocation mechanism (517). Fast packets within a particular traffic type are selected for transmission through use of a head of line priority service (514), a packet discard mechanism (516), or both. The weighted round-robin bandwidth allocation mechanism functions, in part, based upon a credit counter for each queue group that represents a particular traffic type.

摘要： The present invention relates to an N-input, N-output "Knockout" packet switch (11) which uses decentralized control and distributed routing for routing high-speed, time-multiplexed, variable-length packets of information from the N inputs to the N outputs. More particularly, within the switch, the N input signals are separately synchronized such that the start of each arbitrarily arriving variable-length packet is synchronized to the start of a next mini time period of a sequence of mini time periods common to all inputs. The synchronized N input signals then propagate along separate broadcast buses (14) to each of N bus interface units (15) which include N packet filters (20), a concentrator (21) and a shared buffer (22) capable of processing variable-length packets. Each bus interface unit is associated with a separate one of the N outputs (12) of the switch, and the N packet filters therein are each associated with a separate one of the N broadcast buses for detecting if a packet on the associated bus is destined for the associated switch output. The concentrator is used to (a) reduce the number of separate buffers needed to receive packets which may arrive simultaneously and are destined for the associated output, and (b) only directs a maximum of L concurrently arriving packets to the shared buffer while discarding, or "knocking" out, the remainder. Contending packets at the output of the concentrator are stored in the shared buffer before placement on the output line on a first-in, first-out basis. The discarded packet rate of the "knockout" switch can be made as small as desired and latency of packets in the switch is the smallest achievable by any comparable switch.
摘要翻译：本发明涉及一种使用分散控制和分布式路由从N个输入到高速时间复用的可变长度信息分组的N输入，N输出“Knockout”分组交换机（11） N个输出。更具体地，在开关内，N个输入信号被单独地同步，使得每个任意到达的可变长度分组的开始被同步到所有输入共同的一小段时间段的下一小时间段的开始。同步的N个输入信号随后沿独立的广播总线（14）传播到N个总线接口单元（15）中的每一个，N总线接口单元（15）包括N个分组滤波器（20），集中器（21）和共享缓冲器（22）长度包。每个总线接口单元与交换机的N个输出（12）中的单独一个相关联，并且其中的N个分组滤波器各自与N个广播总线中的单独一个相关联，用于检测相关总线上的分组是否发往为关联的开关输出。集中器用于（a）减少接收可能同时到达并发往相关输出的分组所需的单独缓冲器的数量，以及（b）仅在丢弃时将最多同时到达的分组指向共享缓冲器，或“敲门”，余数。集中器输出端的数据包竞争存储在共享缓冲区中，先于先出先出，放在输出线路上。可以使“敲除”开关的丢弃的分组速率尽可能小，并且交换机中的分组的等待时间是通过任何可比较的开关可实现的最小的。
