Description
In this paper the architecture of a new generation router has been presented, It is reconfigurable as it is implemented on a mixed signal Field Programmable Gate Array (FPGA) platform. It is meant to be used in a decentralized structure of new space applications in order to get fast, efficient and reliable transfer of the network packets.
This project is related to a radiation tolerant router which is developed on reconfigurable hardware with state of art microcontroller running under a Real-Time Operating System RODOS. The Real Time Objected Oriented Dependable Operating System (RODOS) was designed specially to be used in satellites. The router is designed to be used in a network of the routers for space applications. Multiple routers can build a complex network on-board. The Ethernet port of each router allows an on-board computers (OBC) to pass communication packets into the network and receive data from it to communicate with each other. The routers forward the message packets through the network to the destination. As the exemplary topology in the figure shows, the network can comprise on loop for introducing redundant communication paths. In order to avoid circular trips of message packets, a dynamic routing protocol must be implemented on the routers such as the (Rapid) Spanning Tree Protocol or Shortest Path Bridging.
