    • An image processing apparatus is connected to a specific network for processing an image according to image information input to the image processing apparatus. The image processing apparatus includes an apparatus information storage unit for storing apparatus information of other apparatus connected to the network; an inquiry unit for inquiring an operational state of the other apparatus according to the apparatus information stored in the apparatus information storage unit; a determining unit for determining the operational state of the other apparatus according to an inquiry result of the inquiry unit; and a switching control unit for switching an operational state of the image processing apparatus between an active state and a power save state according to a number of apparatus that the determining unit determines as being in the active state.
    • 图像处理装置连接到特定网络,用于根据输入到图像处理装置的图像信息处理图像。 图像处理装置包括:设备信息存储单元,用于存储连接到网络的其他设备的设备信息; 查询单元,用于根据存储在设备信息存储单元中的设备信息查询其他设备的操作状态; 确定单元,用于根据查询单元的查询结果确定其他设备的操作状态; 以及切换控制单元,用于根据确定单元确定为处于活动状态的设备的数量,在活动状态和省电状态之间切换图像处理设备的操作状态。

    • A host device is connected to at least one printer through a network. Before printing, the host device broadcasts a query on the network, selects a printer that replies to the query, and sends printer setting information to the printer. The printer includes a setting switch that can be set to different states to accept or reject the printer setting information. A printer replies to the query only if its setting switch is set to the state that accepts the printer setting information. The setting switch avoids the generation of unnecessary replies and thereby simplifies the selection of the printer, as well as protecting the printer from unwanted alteration of its settings.
    • 主机设备通过网络连接至至少一台打印机。 在打印之前,主机设备在网络上广播查询,选择回复查询的打印机,并向打印机发送打印机设置信息。 打印机包括一个设置开关,可以设置为不同的状态来接受或拒绝打印机设置信息。 只有打印机的设置开关设置为接受打印机设置信息的状态,打印机才会回复查询。 设置开关避免了不必要的回复的产生,从而简化了打印机的选择,以及保护打印机免受其设置的不必要的改变。

    • Erroneous detection of a failure in spite of the absence of failure on the route on account of a communication delay is to be prevented. A node device detects a failure on the route to a remote node device is detected by a failure to receive a packet from the remote node device after the elapse of a determined detection time. The node device sets “remote system transmission interval×detection multiplier” to be a first detecting time on the basis of a packet transmission interval determined by negotiation with the remote node device. It also sets the sum of “remote system actual transmission interval ×detection multiplier” and “tolerable delay time” to be a second detecting time. The first detecting time and the second detecting time are compared, and what is longer is determined as the detecting time to be applied to actual operation.
    • 考虑到由于通信延迟而导致路由不存在故障,故障的错误检测是可以防止的。 在经过确定的检测时间之后,通过从远程节点设备接收到分组的故障来检测节点设备检测到到远程节点设备的路由的故障。 节点设备基于通过与远程节点设备协商确定的分组传输间隔将“远程系统传输间隔×检测乘数”设置为第一检测时间。 它还将“远程系统实际发送间隔×检测乘数”和“可容忍延迟时间”的和设置为第二检测时间。 比较第一检测时间和第二检测时间,将更长的时间确定为要应用于实际操作的检测时间。
