Session Setup Time Estimation in the Network with a Firewall

Cover Page

Abstract


In modern telecommunication networks is implemented information transmitting security for protection programs and databases. We propose the approach of signaling messages processing estimation in case when the network includes one firewall and two proxy servers. Firewall is based on security rules and define security police. We choose a session setup procedure between two users using the Session Initiation Protocol as anillustration of the method. Signaling messages are moving from the first user to the second through IP/MPLS network, proxy servers and firewall. The chain of signaling messages must successfully service before media traffic starts. We get preliminary estimation of performance measures for modern firewall Cisco ASA 5500-X with Security Service Processor SSP-10. Numerical example shows, that firewall Cisco ASA 5500-X serves signaling messages can be implemented. Mean waiting time and mean service time in this firewall has little effect on the session setup time and the session request delay.
