Vehicle network with time slotted access and method
First Claim
1. A method of communicating information within a vehicle, the vehicle comprising a network including a plurality of network elements communicatively linked by communication links, the method comprising the steps of:
- providing a data frame;
mapping a first link resource on an incoming communication link of one of the plurality of network elements to a second link resource of an outgoing communication link of the network element, the second link resource being different than the first link resource, at least one of the incoming communication link and the outgoing communication link being a time slotted communication link;
receiving the data frame from the first link resource of the incoming communication link and communicating the data frame to the second link resource of the outgoing communication link.

Abstract
A vehicle network and method for communicating information within a vehicle. The network includes a plurality of network elements joined by communication links. A data frame is provided for communicating information between a first device and a second device attached to the network. A network element in the network is capable of mapping a first resource on an incoming communication link of the network element to a second link resource of an outgoing communication link of the network element. The network element further has ports for receiving the data frame from the first link resource of the incoming communication link and for communicating the data frame to the second link resource of the outgoing communication link. The mapping may be done statically or dynamically such as based on information stored in the network element or based on information stored in the data frame.

10. A vehicle network comprising:
-
a plurality of network elements joined by communication links;
a data frame for communicating information between a first device and a second device, the first device connected to at least one of the network elements and the second device connected to at least one of the network elements;
a processor in at least one of the network elements, the processor capable of mapping a first resource on an incoming communication link of the network element to a second link resource of an outgoing communication link of the network element; and
at least one port in the at least one network element for receiving the data frame from the first link resource of the incoming communication link and at least one port in the at least one network element for communicating the data frame to the second link resource of the outgoing communication link. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method of communicating information within a vehicle, the vehicle comprising a network including a plurality of network elements communicatively linked by communication links, the method comprising the steps of:
-
receiving a data packet from a first link, the data packet being assigned a first time slot assignment;
determining a second time slot assignment for the data packet, the second time slot assignment being different than the first time slot assignment; and
sending the data packet on a second link, the data packet being assigned to the second time slot assignment. - View Dependent Claims (20, 21)
