STATIC RING NETWORK FOR VEHICLE COMMUNICATIONS

摘要

A method for operating a ring network includes the steps of configuring the ring network with static configuration information and then deterministically exchanging operational data between a plurality of nodes on the ring network, while operating the ring network in accordance with the static configuration information. This system facilitates communications that meet the high reliability and performance requirements of vehicle communications, in particular in aircraft data networks (ADNs), while reducing the cost, weight and complexity of conventional implementations.

1. A method comprising the steps of:
(a) configuring a ring network with static configuration information; and (b) exchanging operational data deterministically between a plurality of nodes on the ring network while operating the ring network in accordance with said static configuration information, wherein exchanging operational data deterministically includes guaranteeing a bandwidth, a latency, and jitter of each logical communication channel with traffic flow control, wherein at least a portion of said static configuration information is for guaranteeing quality of service (QoS) on the ring network, and wherein at least a portion of said static configuration information is stored on each of said nodes, and wherein at least one of said nodes is configured to terminate the exchange of a portion of said operational data received from a first direction if said node previously received said portion from an other direction.
