The bus guardian derives a corresponding control signal from an independent set of configuration data. The bus guardian enables communication media access for the communication controller it is assigned to only for specific time slots, for which the communication controller is allowed to transmit data across the communication media.
By means of this configuration data the bus guardian can enable access to the communication media for certain time slots, for which a data transmission by the communication controller the bus guardian is assigned to, is expected. For the remaining time slots access to the communication media is inhibited. TDMA—Time Divisional Multiple Access are implemented, in which more than one node of the communication system can make an attempt for an initial synchronization after power on.
In this phase so called schedule setup it is attempted to synchronize all available nodes in such a way that they act on a global communication scheme, that defines when the nodes can occupy the communication media exclusively. If this synchronization was successful the established time scheme for the nodes will not change anymore.
Each node operates in the so called normal mode. Only a critical operating situation or an intended shut down of the communication among the nodes can lead to a cessation of communication of the node. A change in the access behavior is not permitted. This incident in the following is referred to as schedule-reset.
In contrast to the normal mode described above, the bus guardian must tolerate this incident during a schedule setup phase. Caused by a collision of two or more nodes, which try to achieve an initial synchronization of all nodes at the same time, a situation arises in which all but one node after detection of the collision scenario have to retreat. The node which does not have to retreat remaining node could be a node which first sends a regular frame. Alternatively it could be that node which sends the regular frame last or which sends a regular frame of a certain length.
Then, the chronological location of the own time slots is adjusted to this time schedule. Thus the local communication time schedules of all nodes are brought into a global compliance.
This means that the schedule setup is completed and the communication controllers are synchronized concerning their media access behavior. The communication startup in the distributed system with more than one node being allowed to perform the initial schedule synchronization requires that a node might have to adapt its own access schedule to another one of the nodes, even though it already attempted to startup the communication actively.
This is affected for example by a schedule-reset SRinitiated by the node having to adapt its access schedule to another node. This situation during startup of the communication may lead to allowable deviations for example schedule-reset, RS from the usual communication media access schedule.
In other words, the communication controller is already started up when the communication across the communication system is started up.
The same applies for the bus guardian, which is already started powered up and executing internal logictoo. Both devices just are not yet cooperating to communicate on the channel. What the present invention addresses is how the communication controller and the bus guardian interact to start communication. The problem with the explicit signaling is that the communication controller can indicate a schedule-reset to the bus guardian whenever it wants to.
This allows error scenarios with a communication controller continuously blocking the communication media by periodically signaling schedule-resets to the bus guardian. However, this is exactly what should be prevented by the bus guardian. In such cases the communication controller signals a schedule-reset to a higher-level processing unit, which, for example, is a host controller. The processing unit usually is part of the node and assures the actual functionality of the distributed control system comprising the communication capability and the vehicle control functionality.
An indicated schedule-reset can be validated by the higher-level processing unit and can be forwarded to the bus guardian across an independent interface. A functionality of the node is outsourced to a higher-level entity, which only wants to utilize the data transmission capabilities of the node for realizing the functionality of the distributed control system.
This means that appropriate demands concerning processing speed and reaction time have to be achieved by the processing unit, too, which usually is not the case. In the application software of the processing unit special routines have to be provided which offer a guaranteed latency for detecting, processing and forwarding an event, that is the schedule-reset.
Thus, a node of the communication system cannot be considered a closed entity and therefore is difficult to certify and to check for conformity. An independent operation of these two entities is important in order to reduce their sensitivity against so called common-mode errors. A problem arises if the access behavior of the communication controller to be monitored by the bus guardian changes in compliance with the access scheme and if such an allowable change has to be distinguished from a faulty change caused by a defective communication controller.
A mechanism is proposed that condenses the potential behavior of the communication controller during network startup down to simplified conditions, which can be checked by the bus guardian by observing the communication controller's media access scheme. Each principal function in the company, such as human resources, customer service, or engineering, has been self-contained in its use and maintenance of the data needed by that function.
Each function typically selects its own tools software applications and hardware platformspopulates its own data store, and institutes its own procedures with little regard to the remainder of the enterprise. In cases where there has been limited sharing of data between functions, the implementation has often been an ad hoc gateway between divergent systems and approaches. One approach is to maintain all of the data in one central location.

Furthermore, the remote access to the data requires a communications infrastructure and may consume considerable bandwidth. In most cases, it is usually not known beforehand what particular data may be needed at a given site, so the entire data store must be replicated at each site. While this divides the demands upon the access to the data, this approach introduces problems in maintaining synchronization among the copies of the data.
Furthermore, the replication multiplies the overall storage resources needed, which can be very substantial. If a design is chosen that replicates the data as needed to maintain a certain level of performance in accessing the data, then the overall storage may actually grow as the square of the data size. Typically, in response to requests from points of use that rely on the cache, the local cache selectively downloads data only on an as-needed basis.
The cache will accumulate a self-forming subset of the overall data.
Once loaded, a particular data item in the local cache may be held indefinitely or may be discarded after a time according to a caching algorithm.
Schemes have also been deployed for ensuring that data in the cache is kept current as changes occur in the corresponding data in the master data store. Although a distributed approach introduces some complexities, there are some advantages to be gained. When data resides in a single space, such as data tables in a relational database, it is easy to represent relationships among data elements. There may be a second table wherein each record maps an employee number to a project number department number and internal mail location.

Yet, a third table may have social security numbers mapped to an employee's name and home address. For example, a relationship may be built that enforces a one-for-one relationship between employee number and social security number. Another relationship may allow the same department number to be claimed for many different employees.
In the above example, a database designer may explicitly establish that the employee number field in the first table corresponds to the employee number field in the second table and that, where matching values are found in these two fields, the remainder of the fields in the associated records can be effectively joined to form a composite record. Thereafter, a report may be easily created listing the salary grades of the employees in a given department, despite the fact that the pieces of information are maintained in separate tables.
Properly designed, this separation of data into related tables lends advantages in efficiency and flexibility as is well known in the field of relational database technology. As is well known in computing science, an association among two data objects may be formed by, for example, having either or both of the objects contain a reference or handle or pointer to the other object.
After the second object is created, the first object maintains a memory address for the newly-created second object for the purpose of subsequently accessing the data or invoking the methods of the second object and for ensuring that the second object is properly removed from the memory space when it is no longer needed. Externalized associations have been proposed whereby a first data object and a second data object may be associated by an external entity which maintains a reference to both objects and has a description of how the objects are related.
This implies the use of an external association engine which must be involved whenever a computing task involves cooperation between the first data object and the second data object. Indeed, the association among the first and second data objects may occur well after the objects have been designed and implemented.
Associations may later be formed as needed, as in response to requirements that were not apparent at the time the data objects were initially implemented. Of course, this enables tremendous flexibility in the growth of a distributed computing environment.
To fulfill a needed function, an application may need to draw upon data and functionality from many sources that are separately maintained and often logically or geographically remote from one another.
