    • A system a core (104), an edge node (102, 103) and a method are provided for congestion handling in a packet switched network domain. In case of congestion overload is measured, the data packets in proportion to the overload are marked and the signaled overload is stored. At least one egress node (103) receives marked and not marked packets, decodes and counts the overload from the marked packets in a counting interval. Congestion report messages are sent to ingress nodes (102) where flows are terminated. A core node (104) comprises a storage means (314) taking into account the previously signaled overload, which are already being handled in a congestion handling control loop. An edge node (103) comprises means for adding new flows to the set of affected flows, means for identifying affected flows to be terminated so that the number of identified affected flows should generate together traffic equal to the overload, and means for removing flows to be terminated from set of affected flows. In an advantageous embodiment the market module (315) applies a hysteresis algorithm with a higher bound used to detect congestion and to trigger the marking of user data packets in proportion to the measured overload, and a lower bound used as the reference to measure the overload ratio.
    • 提供了一种核心(104),边缘节点(102,103)和方法,用于分组交换网络域中的拥塞处理。 在测量拥塞过载的情况下,标记与过载成比例的数据包,并存储信号过载。 至少一个出口节点(103)接收标记和未标记的分组,在计数间隔中对标记的分组进行解码和计数过载。 拥塞报告消息被发送到流停止的入口节点(102)。 核心节点(104)包括存储装置(314),其考虑了已经在拥塞控制控制环路中处理的先前发信号的过载。 边缘节点(103)包括用于将新的流添加到受影响的流集合的装置,用于识别待终止的受影响的流的装置,使得所识别的受影响的流的数量应该一起生成等于过载的流量,以及用于去除流到 由一组受影响的流量终止。 在有利的实施例中,市场模块(315)应用具有用于检测拥塞的较高边界的滞后算法,并且与测量的过载成比例地触发用户数据分组的标记,并且下限用作参考以测量过载 比。

    • A simple gateway and an improved controlling method for controlling said gateway are provided to distinguish between different kinds of messages without requiring the gateway to be fully aware of the protocol. The gateway (200c) passes through messages from application entities (310, 320) to network elements (100) or vice versa. The gateway (200c) comprises a transaction identifier determinator (220) to determine a transaction identifier and/or sequence step information determinator (260) to determine sequence step information and a control logic (280) that compares the transaction identifier and/or sequence step information with previously stored ones. From this comparison, it can be determined, whether a message is an initial message or a response message to the initial message and whether the message is a first or a further message, respectively.
    • 提供了一种用于控制所述网关的简单网关和改进的控制方法,以区分不同类型的消息,而不需要网关完全了解该协议。 网关(200c)将来自应用实体(310,320)的消息传递到网络元件(100),反之亦然。 网关(200c)包括事务标识符确定器(220),用于确定事务标识符和/或序列步骤信息确定器(260)以确定序列步骤信息;以及控制逻辑(280),其将事务标识符和/或序列步骤 以前存储的信息。 从该比较可以确定消息是初始消息还是对初始消息的响应消息以及消息是否分别是第一消息或另一消息。
