交换机

One day it is a frame relay switch, the next it is your ISDN router.

这一天是帧中继交换机，这是你们未来的ISDN路由器。

In order to design the high performance ATM switch, it is very important to study on traffic management, especially ABR flow control, in ATM networks.

研究ATM网络的流量管理，特别是其中的流量控制，对设计高性能的ATM交换机是非常必要的。

Chapter 3 introduces the SCM application in the Alcatel Switch development.

第三章介绍软件配置管理在Alcatel交换机研发中的应用。

This invention relates to a structuring method for a multi-allotter front end system of a cluster server characterizing in including the following steps: setting up more than two front end allotters matched with two net cards, a cluster server front end system of a collecting tray, the data input end net cards of the front allotter are cascade via the collecting tray, the data output end net cards of all front allotters are connected with the switching device of the cluster server back end system, the data input end net cards are matched with a same virtual IP, all input data packets are transmitted to all front end distributes in broadcast way, every front server computes, the input data packet IP addresses or TCP port number in hash to decide if said data packet is processed.

本发明涉及网络服务器技术领域，尤其是一种集群服务器的多分配器前端系统构成方法，其特征在于：包括以下步骤，建立包括两台及以上的配置了两块网卡的前端分配器、一台集线器的集群服务器前端系统，所有前端分配器的数据输入端网卡通过集线器并行集联，所有前端分配器的数据输出端网卡与集群服务器后端系统的交换机相连；所有前端分配器的数据输入端网卡配置一个相同的虚拟IP；通过集线器将输入数据包以广播方式传输到所有前端分配器；各前端分配器对输入数据包IP地址或TCP端口号进行散列计算，决定是否处理该数据包。

While troubleshooting a connectivity problem, a network administrator notices that a port status LED on a Cisco Catalyst series switch is alternating

问题：排错一个连接问题，一个网络管理员注意到交换机端口的LED灯不停在绿色和琥珀色之间交替转换，这意味着设么？

While troubleshooting a connectivity problem, a network administrator notices that a port status LED on a Cisco Catalyst series switch is alternating green and amber.

解释一下：CISCO交换机的端口状态指示灯是闪烁的绿色和浅黄色，表示端口有操作的问题——也许是过量的错误或连接的问题。

The backplane's capacity determines the overall capacity of the switch.

背板的容量决定了整个交换机的容量。

An equipment for mixed use of wide-band ADSL and marrow-band cards features that associated LVDS transceiver and on-board connector are installed to ATVC card and WAN card. The high-speed wide band ADSL data line can use LVDS mode to conveniently realize the mixed use of wide-band ADSL and ordinary analog user card on narrow-band speech exchange or the ONU rack of optical network unit. It is connecessary to modify the backplate of POTS and machine rack. The existing narrow-band device can be upgraded to have wide-band access function.

本发明提供了一种宽带ADSL和窄带用户板混插的装置，通过在ATUC板和WAN板上提供相应的LVDS收发器和板上连接器，高速宽带ADSL数据通过背板外LVDS走线方式，可以在普通窄带话音交换机或接入网光网络单元ONU的机框上，方便地实现宽带ADSL与普通模拟用户板之间的混插，这种方法不需要对窄带话音POTS的背板和机框作任何改动，即可实现窄带到宽带的平滑过渡，对已有窄带设备可提供随时升级为宽带数据接入功能的方法及设备。

Unfortunately, because the Batcher sorting network in Batcher-banyan networks can not be scaled modularlly, the application of Batcher-banyan networks in large scale ATM switches still suffers some limitation.

由于Batcher-banyan网络中的Bather排序网络不能进行模块化扩充，因此Batcher-banyan网络在大规模ATM交换机中的应用仍然受到一定的限制。

In Chapter 2, we focus on the performance analysis of internal nonblocking packet switches with Bernoulli traffic arrival model.

在第2章中，研究在贝努里信元到达模型下，内部无阻塞交换机的性能分析。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
