Definitions
- the route finding that is the so-called routing
- the flow control and other tasks relating to the data exchange are standardized, whereby the need for the conversion of addresses is eliminated.
- the protocol of the network layer is formed by the Internet protocol, whereby a network connection can be formed without address-converting gateways and thus additional time delays.
- at least one of the at least two differently structured subnetworks expediently uses a connectionless transport protocol.
- at least one of the at least two differently structured subnetworks uses a connection-oriented transport protocol.
- FIG. 1 shows a comparison of the layer structure of MOST bus system and OSI reference model
- FIG. 2 shows a comparison in the layer structure of an Ethernet-based multimedia network and the OSI reference model
- FIG. 3 shows a schematic representation of a conventional vehicle network system
- Figure 4 shows a schematic representation of a vehicle network system in which the different subnetworks have uniform network layers.
- the layers of a MOST network are compared with the seven layers of the OSI reference model (Open S_system I_connect).
- the application layer 7 according to the OSI reference model is designed as a programming interface in the MOST network.
- the tasks of the presentation layer 6 according to the OSI reference model assume the "network services 2" layer in the MOST network.
- the services of the communication control layer 5, transport layer 4 and network layer 3 are in the MOST network of the "network daisy chain 1 and layer 1 of the OSI reference model are referred to in the MOST network as the "Most Transceiver" or "MOST physical layer".
- the layer model of a network for multimedia applications whose bit transmission and data link layers are designed according to the Ethernet standard, is compared with the OSI reference model.
- the network layer of the Ethernet based multimedia network is based on the internet protocol.
- TCP Transmission Control Protocol
- UDP User Datagram Protocol
- the latter are especially used in streaming media, where audio or video data is transmitted continuously over the network.
- the encoding, packaging and sending of multimedia data streams is performed at the session layer by the Real-Time Transport Protocol (RTP), which interacts with the Real-Time Control Protocol to issue and maintain Quality of Service (QoS).
- RTP Real-Time Transport Protocol
- QoS Quality of Service
- Controlling and controlling the transmission of realtime-sensitive multimedia data are the subject of the Real-Time Streaming Protocol (RTSP).
- the connection-oriented transmission of data is handled in the session layer by Hypertext Transfer Protocol (HTTP).
- HTTP Hypertext Transfer Protocol
- MPEG-4 and UPnP are used in the presentation layer.
- the task of the network layer is generally to route data packets from the origin to the destination. It forms the lowest layer for establishing a connection between two end systems, which end systems can be connected to one or the same or to different networks.
- the network layer the addressing and the correct assignment of source and destination address takes place.
- each subnetwork has a network layer designed differently from the network layers of the other subnetworks. This also differentiates the address assignments in the individual subnetworks.
- FIG. 3 shows a schematic representation of a conventional vehicle network system 100, in which the end systems of three different networks are interconnected via gateways 10, 20, 30 and 40.
- the gateway 10 binds the end systems 11, 12, 13 and 14 of the first one
- Gateway 30 connects the end systems 31, 32, 33 and 34 of a second subnetwork to the network system 100 of the vehicle, wherein the connection via another gateway 20 (for example, another, not detailed in the figure subnet) takes place.
- the end systems 41, 42, 43 and 44 of a third subnet are finally connected via the gateway 40 to the vehicle network system.
- the communication protocols When transmitting a message from one of the subnets to another, the communication protocols must be converted in the gateways. If, for example, a message is transmitted to the end system 43 by the end system 11, the message must pass through the gateways 10, 20 and 40. This is associated with a transition to the protocol of the subnet in which the message is transmitted.
- the message can be broadcast in the form of a broadcast to all end systems, with the end systems themselves deciding whether the message is relevant to them.
- the network system can also have a corresponding address management, in which the subnets assign messages from a source address to one or more corresponding destination addresses. Since the addressing takes place in the network layer, the address for the destination system of a directory must be converted in the gateways on the way to the subnet of the destination system, whereby the transmission of a message It increases the required processing power and extends the transmission time.
- the protocols of the individual network layers are uniform in all the different subnets, as a result of which the network layers of the differently structured or structured subnetworks are identical in their structure.
- This achieves uniform addressing of the end systems within the vehicle network system built up from differently constructed subnetworks.
- the need for implementing the addresses of messages or data is eliminated at the gateways even when messages or data are transmitted from one end system of a subnet to one end system of another subnet that has a different structure for this subnet.
- conversions on the hardware layer defined by the backup and physical layer continue to be made via appropriate coupling elements.
- the protocol used by the network layer is the Internet Protocol (IP), since the vehicle network system thereby uses e.g. can be constructed as a private network, which can then communicate via a gateway or a router with a globally unique IP address with other networks outside the vehicle, such as a garage network, a navigation network or the like.
- IP Internet Protocol
- the unique Internet address of the vehicle also makes car-to-X communication in particular easy to design.
- multi-user multimedia can be realized in the vehicle since, if in the network system of the vehicle, e.g. already a video stream is transmitted, a second multimedia location due to the unique source address of the video stream can easily access this video stream. Furthermore, since the address assignment in the Internet Protocol is unique, new end systems such as e.g. simply and safely integrate a new radio into the network system of the vehicle.
