摘要： A packet transport system to which the present invention is applied includes an edge node accommodating an access network at an edge, and a core node of carrying out a processing of assorting a frame gathered from a plurality of the edge nodes, the edge node provides a label to the frame flowing in from the access network, and the packet transport system transmits the frame in reference to the label. The edge node includes a priority information providing portion of changing a piece of priority information provided to the frame flowing in from the access network in accordance with a congested state of the core node, and a priority previously set to a path specified by the label.

摘要： An identifier management apparatus capable of setting identifier conversion information of a new user without affecting identifier conversion processings of other users, and an identifier management method. The identifier management apparatus converts an identifier given to communication data. Its memory stores multiple hash functions, output values of the hash functions corresponding to the respective plurality of hash functions, multiple entry tables that manage the identifier conversion information indicating a correspondence between the input identifier being an input value of the hash function and an output identifier obtained by converting the input identifier, and a management table for managing a setting status of the identifier conversion information in each entry table. When registering the new identifier conversion information in any entry table, its processor selects an entry table that should register new identifier conversion information depending on setting statuses of the identifier conversion information in the entry tables.

摘要： In a cache control assuming plural user terminals accessing identical content, cache delete priority assignment is performed from a position where a user finished playback based on whether the user intends to view the content later. A cache control server is provided, and a cache delete inhibit span is determined based on a playback stop position or a normal speed playback time. A cache server deletes the cache based on the delete inhibit span received from the cache control server. Traffic of the core network due to re-cache can thus be reduced.

摘要翻译：在假设多个用户终端访问相同内容的缓存控制中，基于用户是否稍后想要查看内容，从用户完成重放的位置执行高速缓存删除优先级分配。提供了缓存控制服务器，并且基于重放停止位置或正常速度重放时间来确定高速缓存删除禁止范围。缓存服务器根据从缓存控制服务器接收的删除禁止范围删除缓存。因此可以减少因重新缓存而导致的核心网络的流量。
