    • An encrypted-traffic discrimination device includes an input interface, a flow discrimination section, a data accumulation section, a selective data calculation section, a calculation result determination section, and an output interface. The flow discrimination section discriminates the input traffic into separate flows based on at least a transmission origin address and a transmission destination address. The data accumulation section accumulates characteristic amount data of the traffic for each of the separate flows. The selective data calculation section executes an evaluation computation utilizing specific data from the characteristic amount data. The calculation result determination section that, based on a calculated evaluation computation value, executes threshold value determination to determine whether or not the traffic is encrypted, and, if the traffic is determined to be encrypted, which encryption format the traffic is encrypted with.
    • 加密流量判别装置包括输入接口,流量鉴别部,数据存储部,选择性数据计算部,计算结果判定部,输出接口。 流检测部分至少基于发送源地址和发送目的地地址将输入业务区分为单独的流。 数据累积部累积各流量的流量的特征量数据。 选择性数据计算部使用来自特征量数据的特定数据来执行评价计算。 计算结果确定部,其基于计算出的评价运算值,执行阈值判定,判定是否加密了业务,并且,如果确定要加密的业务,则加密业务的加密格式。

    • Routing schemes are provided for a communication network. In one scheme, destination terminals and associated neighboring terminals are listed in a routing control cache at each communication terminal in the network, and packets are routed toward the destination terminal through the associated neighboring terminals. In another scheme, a single path from a source terminal to a destination terminal is automatically expanded into multiple paths. In yet another scheme, packets are routed as long as this does not increase the number of hops to the destination terminal. These schemes enable multiple paths to be established by a simple procedure not requiring complex distance calculations. In still another scheme, routing is restricted to the shortest path and paths up to a given number of hops longer than the shortest path, permitting paths to diverge in multiple directions from the source and destination terminals.
    • 为通信网络提供路由方案。 在一种方案中,目的地终端和相关联的相邻终端被列在网络中的每个通信终端处的路由控制高速缓存中,并且分组通过相关联的相邻终端被路由到目的地终端。 在另一方案中,从源终端到目的终端的单一路径被自动扩展成多个路径。 在另一种方案中,只要这不增加到目的地终端的跳数,分组被路由。 这些方案使得能够通过不需要复杂距离计算的简单过程来建立多个路径。 在另一种方案中,路由被限制到比最短路径更长的给定跳数的最短路径和路径,允许路径从源终端和目的地终端在多个方向上发散。
