Abstract: A vehicle tracking system central host comprises a memory cache processor for managing a plurality of memory caches and a storage device linked with the memory cache processor, for receiving messages from the memory caches and writing them to a database. There are n receiver ports each for receiving message packets of an associated protocol from remote vehicle on-board tracker units. There are also n receiver processors, each associated with a port and each receiver processor being for: reading message packets received at the associated port, performing initial processing of the message packets including adding headers to provide processed messages, and writing the processed messages to a log dedicated to the receiver processor.
