摘要： The amount of chip power that is consumed for cache storage size maintenance is optimized by the close monitoring and control of frequency of missed requests, and the proportion of frequently recurring items to all traffic items. The total number of hit slots is measured per interval of time and is compared to the theoretical value based on random distribution. If the missed rate is high, then the observed effect and value of increasing cache size are deduced by observing how this increase affects the distribution of hits on all cache slots. As the number of frequently hit items in proportion to the total traffic items increases, the benefits of increasing the cache size decreases.
摘要翻译：高速缓存存储大小维护所消耗的芯片功率的数量通过密切监视和控制错误请求的频率以及频繁重复的项目与所有流量项目的比例来优化。每个时间间隔测量命中时隙的总数，并根据随机分布与理论值进行比较。如果错过率高，则通过观察这种增加如何影响所有高速缓存槽上的命中分布，推导出观察到的增加高速缓存大小的效果和值。随着与总交通项目成比例的频繁点击项目的数量增加，增加高速缓存大小的好处减少。

摘要： Methods and apparatus are provided for controlling flow rates of a plurality of data packet flows into a queue 4 corresponding to a resource 3 of a network device 1. The flows comprise a set 7 of non-responsive flows, and a set 8 of other flows which may comprise responsive flows and/or flows whose responsiveness is unknown. The flow rates are managed in accordance with a queue management scheme such that adjustments are made to each flow rate in dependence on excess bandwidth in the resource, the amounts of the adjustments being dependent on one or more adjustment parameters for each flow. An error signal is generated based on the deviation from a desired allocation ratio of the ratio of the total flow rates into the queue 4 for the sets of flows 7, 8. At least one adjustment parameter for at least one flow is then varied in dependence on the error signal in such a manner as to reduce the aforementioned deviation. A closed-loop control scheme thus operates in conjunction with the underlying queue management scheme to promote fair bandwidth allocation even in the presence of a mix of responsive and non-responsive flows.

摘要： A method and system for managing asynchronous transfer mode (ATM) traffic in a computer system is disclosed. The computer system is used in sending, receiving, or sending and receiving a plurality of ATM flows. Each ATM flow has a plurality of ATM cells, a minimum ATM bandwidth guarantee, and a maximum ATM bandwidth. The method and system include determining whether excess bandwidth exists for the ATM flows. The method and system also include gracefully increasing a portion of the ATM cells transmitted for each ATM flow during periods of excess bandwidth. The portion of the ATM cells transmitted is not more than the maximum ATM bandwidth limit. If an ATM flow presents a sufficient offered load, the portion of the ATM cells transmitted in the flow is not less than a minimum ATM bandwidth guarantee.

摘要： A codec detects congestion in a packet network and responds via a session control protocol to re-negotiate codec-type and/or parameters with the receiving codec to reduce bit rate for supporting a session. Once the connection and session are established, encoded packets start flowing between the two codecs. A control entity sends and receives network congestion control packets periodically in the session. The congestion control packets provide a “heartbeat” signal to the receiving codec. When the network is not congested, all “heartbeat” packets will be passed through the network. As network congestion increases, routers within the network discard excess packets to prevent network failure. The codecs respond to the missing packets by slowing down the bit rate or proceeding to renegotiate a lower bit rate via the session control protocol. If there are no missing packets, the codecs detect if the session is operating at the highest bit rate, and if not, re-negotiate a higher bit rate.
摘要翻译：编解码器检测分组网络中的拥塞，并通过会话控制协议进行响应，以使用接收编解码器重新协商编解码器类型和/或参数，以减少支持会话的比特率。一旦建立了连接和会话，编码的数据包将在两个编解码器之间开始流动。控制实体在会话中定期发送和接收网络拥塞控制报文。拥塞控制分组向接收编解码器提供“心跳”信号。当网络不拥塞时，所有“心跳”数据包将通过网络传递。随着网络拥塞的增加，网络内的路由器丢弃多余的数据包，防止网络故障。编解码器通过减慢比特率或通过会话控制协议进行重新协商较低的比特率来响应丢失的分组。如果没有丢失数据包，则编解码器检测会话是否以最高比特率运行，如果不是，则重新协商更高的比特率。

摘要： A detection and response system that generates an Alert if unauthorized scanning is detected on a computer network that includes a look-up table to record state value corresponding to the sequence in which SYN, SYN/ACK and RST packets are observed. A set of algorithms executed on a processing engine adjusts the state value in response to observing the packets. When the state value reaches a predetermined value indicating that all three packets have been seen, the algorithm generates an Alert.

A first blocking measure A is independently applied at respective ones of the plurality of nodes to the anomalous traffic that stops the anomalous traffic.

摘要： The present invention provides for a computer network method and system that applies “hysteresis” to an active queue management algorithm. If a queue is at a level below a certain low threshold and a burst of packets arrives at a network node, then the probability of dropping the initial packets in the burst is recalculated, but the packets are not dropped. However, if the queue level crosses beyond a hysteresis threshold, then packets are discarded pursuant to a drop probability.Also, according to the present invention, queue level may be decreased until it becomes less than the hysteresis threshold, with packets dropped per the drop probability until the queue level decreases to at least a low threshold. In one embodiment, an adaptive algorithm is also provided to adjust the transmit probability for each flow together with hysteresis to increase the packet transmit rates to absorb bursty traffic.

摘要： Methods and apparatus are provided for managing a data packet queue corresponding to a resource of a network device. A token count TC is maintained for a predefined flow of data packets, and the transmission of packets in the flow into the queue is controlled in dependence on this token count. The token count is decremented when packets in the flow are transmitted into the queue, and the token count is incremented at a token increment rate C. A bandwidth indicator, indicative of bandwidth availability in the resource, is monitored, and the token increment rate C is varied in dependence on this bandwidth indicator. The bandwidth-dependent variation of the token increment rate C is such that, when available bandwidth is indicated, the increment rate C is increased, and when no available bandwidth is indicated the increment rate C is decreased.
