Detection of a need to establish and establishment of a communication channel over an interface of a computer system using a communication protocol

The communication resource of the communication protocol such as internet protocol of version 4 and 6 is obtained temporarily upon detection of communication requirements of the computer system (1-3). The communication resource is assigned to the interface of the computer system. One trigger event of the network layer parent layer of the computer system for establishing the communication channels (12,13,21,22,32,33) are predefined. The upper layer of network layer is monitored for occurrence of one trigger event, for recognizing the communication requirements of communication system. An independent claim is included for computer program for recognizing demand and establishing communication channel via interface of computer system.
