In a packet switching network, each new session requested by a terminal involves first establishing a path throughout the network. This is made possible by including focal points permanently keeping a picture of the busy paths. When a new session is to be established for realtime traffic (e.g. voice), the systems must be able to select and establish the optimal path in terms of transmission delay and risks of losing packets, meaning here intentionally discarding overdelayed packets within network nodes, since node traffic is being conveyed through queues, i.e., shift registers with limited length. In case of node traffic overload, packets are to be discarded to match the registers capacity. This operation is conventionally referred to as "clipping".
