Abstract: According to one embodiment, 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 signaling packet, which is received at an interface of the network node and characterized by an entry in the protocol field of the header of the IP-packet, is routed through the IP-tunnel to the control component.

Abstract: IP packets are received, identified, evaluated and processed at interfaces of a network node in a communications network, which comprises a number of network nodes and which transmits IP packets. An in-band IP signaling packet, which is received at an interface of the network node, is identified at the interface and is characterized by an entry in the protocol field of the header of the IP packet, a one-to-one value, which is assigned to the receiving interface and which differs from the values of the other interfaces is entered in a field of the IP header of the IP packet and the modified packet is sent to the control component.

Abstract: With the advent of multimedia in computer systems, it is necessary to integrate audio and video in the computer as data types equivalent to text and graphics. For this purpose, provision is made of program modules which carry out different tasks. In order to define the properties of each audio/video device, an endpoint module is generated for each audio/video device and then forms the interface to the remaining modules. When a data packet is to be transmitted from one device to another device, an event or a request is generated, which is evaluated by an event module, which then selects the corresponding endpoint modules and establishes a logical link between these endpoint modules. The data packet is controlled by means of a data module, which also initiates the storage of the data packet. Following termination of the transmission of the data packet, the event module searches for further requests which can, for example, be held in a queue in a waiting loop.
