摘要
The method and arrangement according to the present invention relate to communication networks using ATM-(Asynchronous Transfer Mode) connections for data transmission, particularly ATM-connections adapted for transmission of, e.g., IP-packets. Transmission of IP-packets via an IP-link in an ATM-based communication network is done by a link function block that is implemented between IP-level and ATM-level. The function block includes selector for selecting an operative ATM-connection, which is assigned to said IP-link, monitor for monitoring the operability of selected ATM-connections and re-selector for reselecting a redundant ATM-connection if one of the assigned connections is detected to be inoperative.
