In this paper a secure error-signalling scheme for packetswitched network architectures is presented. Current solutions are based on the Internet Control Message Protocol to deliver information regarding congestion control. The disadvantages of ICMP are given, regarding its limitations and dependence on network protocol structures. We then move into presenting the Future Core Network System, followed by an analysis of the FCNS Error Protocol and its comparison against ICMP. We also present measurements taken to observe the performance of the FCNS in cases where the FCNSEP implementation has been imperative and reveal applicability issues for the FCNSEP in network protocol systems.
