Performance improvements using upgrading precedences in MIL-STD-188-220 standard

Abstract

Deterministic Adaptable Priority Net Access Delay, one of the channel access methods defined in MIL-STD-188-220 standard, is designed focusing on the reliable transmissions of the highest priority packets. Therefore, it degrades the performances of the low priority traffics. This paper proposes a method to improve the performances of the low priority traffics while maintaining the performances of the highest priority traffics. The method upgrades intentionally the priority of the traffics that stays in a queue for a certain time period, so that it gives an opportunity for even lower priority traffic to be transmitted. The proposed method is simulated and the results show it improves the network performances. © 2013 Springer Science+Business Media Dordrecht(Outside the USA).
