Abstract: The present invention relates to a telecommunications node (60) that is able to handle IP-traffic and to terminate telecommunications traffic. The node includes a forwarding functionality with a number of forwarding engines (65). The node includes means for creating internal IP-hosts (61) for terminating IP-traffic within the node (60), each of which IP-host is attached to an IP-port (83) of a forwarding engine (65). The IP-hosts are each assigned an individual IP-address, which makes it possible to forward IP-traffic to the IP-hosts (61) by means of using the IP-address as a destination address for the IP-traffic. Information relating to the IP-addresses of the internal IP-hosts (61) is included in forwarding tables of the forwarding engines (65). It is possible to perform load distribution of terminating IP-traffic based on the IP-addresses of the internal IP-hosts.

Abstract: 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.

Abstract: A telecommunications platform (20) has a cluster (32) of processors (30) which collectively perform a platform processing function. Plural processors of the cluster have Internet Protocol (IP) capabilities and respective plural IP interfaces (34). An Internet Protocol (IP) handler (60) distributed throughout the cluster facilitates applications executing on the plural processors comprising the cluster to be addressed using a same media access layer (MAC) address. That is, the Internet Protocol (IP) handler comprises a single IP stack (62) which is addressed with the same media access layer (MAC) address. The Internet Protocol (IP) handler comprises a media access control (MAC) bridge (70).
