路由器

For dial peer hunting to work, the originating router must be configured with a list of dial peers, all of which can route a call to the same endpoint, but using different destination routers.

为使拨号点搜寻开始工作，起始路由器必须配备拨号点的列表，能利用不同的目的地路由器将一个呼叫路由到同一端点。

Firstly, according to the generalized router architecture, a variety of blockings during the transfer process are analyzed in this paper, and then an analytical router model which uses M/G/1/N queuing system is proposed. Secondly, an NoC performance analysis algorithm is presented,and the formulas for packet delay and saturated throughput are obtained.

首先从NoC路由器工作原理出发，对报文传输中的各种阻塞现象进行分析，建立了基于M/G/1/N排队系统的路由器模型；然后提出NoC网络性能分析算法，并且给出了传输延迟、饱和吞吐率等参数的解析表达式。

Emulations also tell us PGMF algorithm is fit for both small-scale routers and big scale high performance routers.

仿真还发现，PGMF算法不但适用于小规模路由器，而且更加适用于大规模高性能路由器。

Especially, more attention is paid to the blocking performance of the router with limited wavelength convertible capability. And it is seen by the numerical computing that low conversion degree of the wavelength converter is more realistic to construct a wavelength router system with accurately tunable devices not used, not only switching time is to be minished, but also the complexity of carrying out in engineering is reduced.

尤其在受限波长转换条件下的配置优化分析，可看出波长路由器无需可调谐器件，也能获得灵活的波长转换能力，不但可避免波长路由器因为精确调谐所开销的时间，而且所有的控制均为简单的开关控制，可降低工程实现的复杂度。

A: Each of these routers is connected to one or more additional router, as shown.

其他的路由器则是与一个或更多的路由器相连，如显示。

The method to configure RED parameters based on network properties is also presented. Simulations show that the modified Random Early Detection algorithm really performs better than the original Random Early Detection algorithm and can work for a much wider range of traffic. Finally, whether the assured service mechanisms i. e. an edge router tags every arriving packet of a TCP flow based service profile and core router drops packets differently at congestion using active queue management scheme is possible to provide a throughput consistent with target rate, is investigated under different network scenarios. Different factors including target rate tagged algorithm, RIO algorithm and TCP congestion control mechanism how to affect the throughput of an assured service TCP flow are examined. Based on a fluid model. we then derive a model of an assured service TCP flow, which is the function of round trip delay, packet loss rate and token bucket parameters. Based on this model, we observe that in some cases it is possible to regulate the token bucket parameters to gain a consistent throughput with the target rate, while in other cases there exist ranges of values of the achieved rate for which the token parameters have no influence. With the latter, some modified TCP congestion control mechanisms to assure TCP throughput are proposed.

最后，在区别服务网络结构内，研究了当前提出的一种边缘路由器根据服务合同标记、分类数据包，结合内部路由器采用主动队列缓冲管理机制区别处理数据包的确信服务机制是否可在不同网络情况下使TCP连接获得同目标速率相一致的、公平的吞吐量问题；指出影响TCP连接获得同目标速率相一致吞吐量的主要因素是目标速率大小、标记算法参数和TCP连接的拥塞控制算法；对此，基于流模型假设，首次推导出一个以端到端时延、数据包丢失率、漏桶参数为变量的确信服务TCP连接吞吐量模型；利用这个模型进行分析，得到主要结论是在一些情况下可通过设置合适的漏桶参数得到同目标速率更一致的吞吐量，而在另一些网络情况下不管如何设置漏桶参数都不能使TCP连接获得同目标速率一致的吞叶量；对于后一些情况，还初步讨论了改进TCP拥塞控制算法来改善TCP连接性能的方法。

If the sending end station determines that the destination address is not local ,the packet goes to a first－hop router ,typically one that is close and has been preassigned to the sender.

如果发送端站确定目的地址不在本地，该包就被送到第一跳路由器，一般来说，该路由器是在附近的，并已被预先分配给发送者。

There are tools for generating router configuration files, displaying and checking routes, generating aggregations of networks, etc.

它拥有一些工具，用于生成路由器配置文件，显示和检测路由器，生成网络集合等等。

Then,we give some description about the working principle,organization,function of router-cache and where it should be. We also gave out a cache coherence protocol for multiprocessors systems with router-caches.

本文接着描述了路由器cache的工作原理，对其的组织、在系统中的位置、应有的功能等方面进行了讨论，并设计了含有路由器cache的多处理器系统的cache一致性协议。
