    • The present invention relates to methods and routing and/or switching devices for determining a path maximum transmission unit MTUP(n) size for transmission paths between edge nodes in a data communications network and for updating routing tables associated with the routing and/or switching devices in said edge nodes, which are linked together with link interfaces L(i) constituting transmission paths P(n) for data packet transmission, each link interface L(i) having a link interface maximum transmission unit MTUL(i) size. The methods involve the acquisition of a link interface maximum transmission unit MTUL(i) size for a link interface L(i), and the updating the routing table by calculating the path maximum transmission unit MTUP(n) size for each destination that involves the link interface L(i) for the acquired link interface maximum transmission unit MTUL(i) size. New link-state protocols for distributing the link interface maximum transmission unit MTUL(i) size is also provided.
    • 本发明涉及用于确定数据通信网络中的边缘节点之间的传输路径的路径最大传输单元MTUP(n)大小并用于更新与路由和/或交换设备相关联的路由表的方法和路由和/或交换设备 在与构成用于数据分组传输的传输路径P(n)的链路接口L(i)链接在一起的所述边缘节点中,每个链路接口L(i)具有链路接口最大传输单元MTUL(i)大小。 所述方法涉及获取链路接口L(i)的链路接口最大传输单元MTUL(i)的大小,并且通过计算涉及到每个目的地的每个目的地的路径最大传输单元MTUP(n)的大小来更新路由表 用于获取的链路接口最大传输单元MTUL(i)大小的链路接口L(i)。 还提供了用于分发链路接口最大传输单元MTUL(i)大小的新的链路状态协议。
