METHOD FOR ROUTING IP-PACKETS TO AN EXTERNAL CONTROL COMPONENT OF A NETWORK NODE IN AN IP-PACKET SWITCHING COMMUNICATIONS NETWORK COMPRISING SEVERAL NETWORK NODES

摘要

According to said method, IP-packets are received, identified, evaluated and processed at interfaces of a network node. An IP-tunnel is established from each interface of the network node to the control component. An in-band IP signalling packet, which is received at an interface of the network node and characterised by an entry in the protocol field of the header of the IP-packet, is routed through the IP-tunnel to the control component.
