Interconnection of subnetworks by a uniform network layer
View Patent ↗A network system for motor vehicles, including at least two differently structured subnetworks which each have a data connection, the network layers of the at least two differently structured subnetworks having a similar structure. The protocol of the network layer is preferably the Internet Protocol.
1. A network system for a motor vehicle, comprising:
a first subnetwork arranged in the motor vehicle and having a first configuration including a first data link layer; and
a second subnetwork arranged in the motor vehicle and having a second configuration that is different than the first configuration and including a second data link layer,
wherein respective network layers of the first and second subnetworks are of the same design such that a same addressing scheme is used for end systems on the first and second subnetworks, and
whereby addressing between the first and second subnetwork is performed without address conversion by a gateway for a respective end system in a respective subnetwork.
2. The network system as claimed in claim 1 , wherein a protocol of the network layer is an Internet Protocol.
3. The network system as claimed in claim 2 , wherein at least one of the first and second subnetworks uses a connectionless transport protocol.
4. The network system as claimed in claim 2 , wherein at least one of the first and second subnetworks uses a connection-oriented transport protocol.
5. The network system as claimed in claim 1 , wherein at least one of the first and second subnetworks uses a connectionless transport protocol.
6. The network system as claimed in claim 5 , wherein at least one of the first and second subnetworks uses a connection-oriented transport protocol.
7. The network system as claimed in claim 1 , wherein at least one of the first and second subnetworks uses a connection-oriented transport protocol.
8. The network system as claimed in claim 1 , wherein the first subnetwork is a MOST (Media Oriented Systems Transport) network and the second subnetwork is an Ethernet network.
9. The network system as claimed in claim 8 , wherein a maximum data rate is defined for communication between the at least the first subnetwork and the second subnetwork.
10. The network system as claimed in claim 9 , wherein a packet format is defined for communication between the at least the first subnetwork and the second subnetwork.
11. The network system as claimed in claim 8 , wherein a packet format is defined for communication between the at least the first subnetwork and the second subnetwork.
