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： A method and apparatus for protection switching in a ring network are provided. A method for protection switching in a ring network, which includes a first ring network having first and second connection nodes and a second ring network connected with the first ring network through the first and second connection nodes, includes: receiving, by the first connection node, first and second R-APS messages transmitted from nodes belonging to the first ring network; determining, by the first connection node, the position of closure in the first ring network by using the first and second R-APS messages and topology information; receiving, by the first connection node, a topology change signal transmitted from the second ring network; and transmitting, by the first connection node, an FDB flush message with reference to the position of closure.
