Implementation of AFDX Switch on ZYNQ FPGA

Avionics Full-Duplex Switched Ethernet Network (AFDX), originally The Word “Avionics” is the combination of the Aviation and electronics, which could be defined as electronics of aircrafts, artificial satellites and spacecrafts.MIL-1553 as its communication protocol for Avionics projects. But MIL-1553 communication is half duplex, asynchronous and works at 1Mbps which may not be able to cater to the future communication performance requirements of bandwidth and maintainability. So a need exists to improve bandwidth, reliability and maintainability while at the same time reducing the physical dimensions of size, weight and number of connectors. A new network infrastructure is needed to provide more flexibility in avionics system design and cope with the increasing number of interconnections between systems. The proposed project is implementation of 8 -port AFDX switch on ZYNQ FPGA and also to form a deterministic network means that all the AFDX End systems connected through AFDX switches via Virtual links, Finally the utilizes data speed is 100Mbps full-duplex switched Ethernet according to ARINC-664Part7. Merits of this project is redundancy can be achieved i.e. there is no repetition of frames at output of end-system and another one is complexity of the network can be reduced. This entire work is implemented in Xilinx Vivado 2014.4 and Xilinx 14.6 ISE simulator and the packet flow at the end-system can be captured by Wire-shark software.
