摘要： A method of transmitting packets over a network includes steps of transmitting a first plurality of test packets during a first plurality of time locations that are coarsely spaced apart in time; determining which of the first plurality of time locations corresponds to favorable network traffic conditions; transmitting a second plurality of test packets over the network during a second plurality of time locations that are finely spaced apart in time, wherein the second plurality of time locations are selected on the basis of favorable network traffic conditions; determining which of the second plurality of time locations corresponds to favorable network traffic conditions; and transmitting data packets over the network using one or more favorable time locations determined by the finely spaced test packets. The method can be used to “zero in” on congested network periods by detecting differences in packet latencies among test packets.
摘要翻译：一种通过网络发送分组的方法包括以下步骤：在时间上粗略间隔的第一多个时间位置发送第一多个测试分组; 确定所述第一多个时间位置中的哪一个对应于有利的网络业务状况; 在时间上精细间隔的第二多个时间位置通过网络发送第二多个测试分组，其中基于有利的网络业务状况来选择第二多个时间位置; 确定所述第二多个时间位置中的哪一个对应于有利的网络交通状况; 以及通过使用由精细间隔的测试分组确定的一个或多个有利时间位置在网络上发送数据分组。该方法可以通过检测测试包中的数据包延迟的差异，在拥塞的网络周期中“零入”。

摘要： A system including a broadband switch includes a controller which coordinates video call set-up and a switch for connecting various phone lines together through diplexers. The system permits video telephone conferencing and other video related applications to be performed over ordinary telephone wires. Two diplexer/modems are typically provided for each user: one at the user's telephone jack and another at the central PBX location for that user's telephone line. The PBX connections can usually be made in a central wiring closet. A video server can also be provided which retrieves video images from disk to provide on demand to users. the existing PBX handles the switching of normal telephone audio signals, and a broadband data switch handles the switching of broadband signals over the same telephone wires that the PBX uses. The broadband switch essentially “piggybacks” off the PBX system and avoids interference with telephone signals through the use of diplexers.
摘要翻译：包括宽带交换机的系统包括一个协调视频呼叫建立的控制器和一个通过双工器连接各种电话线的交换机。该系统允许通过普通电话线执行视频电话会议和其他视频相关应用。通常为每个用户提供两个双工器/调制解调器：一个在用户的电话插孔，另一个在该用户的电话线的中央PBX位置。 PBX连接通常可以在中央配线柜中进行。还可以提供视频服务器，其从磁盘检索视频图像以便按需向用户提供。现有的PBX处理普通电话音频信号的切换，宽带数据交换机通过与PBX使用的相同电话线处理宽带信号的切换。宽带交换机本质上“搭载”PBX系统，并通过使用双工器避免对电话信号的干扰。
