Abstract:
Network performance increase does not have to be associated only with the upgrade of existing infrastructure and devices. More effective and less expensive increase of network performance can be achieved via sophisticated improvement of existing protocols, mainly at network and transport layer.
The aim of this paper is to introduce our new approach for solving network performance issues which occur mostly due to congestion. New approach called Advanced Notification Congestion System (ACNS) allows TCP flows prioritization based on the TCP flow age and carried priority in the header of the network layer protocol. The main aim is to provide more bandwidth for young and high prioritized TCP flows by means of penalizing old greedy flows with a low priority. Using ACNS, substantial network performance increase can be achieved.
