摘要： A ring protection link (RPL) owner node in a ring network transmits a ring-automatic protection switching (R-APS) frame in a burst mode until blocked ports of all nodes except the RPL owner node have been unblocked, and, if it is determined that all the nodes have been unblocked, transmits the R-APS frame in a continuous mode. In this manner, the time required to unblock all the nodes can be reduced.
摘要翻译：环网中的环网保护链路（RPL）所有者节点以突发模式发送环路自动保护倒换（R-APS）帧，直到除RPL所有者节点以外的所有节点的阻塞端口被解除阻塞，如果是确定所有节点已被解除阻塞，以连续模式发送R-APS帧。以这种方式，可以减少解锁所有节点所需的时间。

摘要： Provided is a network flow-based scalable video coding (SVC) adaptation device. Without permitting a network transmitting end to divide image data into image data having various levels of quality and send the image data having the various levels of quality to all networks, since an adaptation device is installed in a network device of an ingress of a lower network of a subscriber and the adaptation device and the network transmitting end share network information about attributes of a terminal and the lower network of the subscriber so as to provide an image service having image quality corresponding to the terminal to the terminal, network efficiency can be maximized.
摘要翻译：提供了一种基于网络流的可伸缩视频编码（SVC）适配装置。不允许网络发送端将图像数据划分成具有各种质量等级的图像数据，并将具有各种质量等级的图像数据发送到所有网络，因为适配装置安装在下网络的入口的网络设备中的用户和适配设备以及网络发送端共享用户的终端和下层网络的属性的网络信息，以便向终端提供具有与终端对应的图像质量的图像服务，网络效率可以最大化。

摘要： A node generates a delay measurement frame and transmits it to an adjacent node of an Ethernet ring network in order to measure a delay of the network. The node receives the delay measurement frame generated by the node from another adjacent node of the ring network, and measures a network delay by using the received delay measurement frame.
