The ILP based on source formulation is newly proposed in recent literatures. This paper firstly applies the ILP based on source formulation into the current popular Waveband switching (WBS) network. Our research shows that the ILP based on source formulation can effectively improve the network performance. Two optimized WBS network scenarios are discussed in this paper, including the networks constructed with multi-granular OXCs (MG-OXC) and the networks which is not limited to MG-OXCs but constrained by the condition that all wavebands only contain lightpaths to the same destination. Numeric results show that source-formulation ILP can require less computational effort compared to flow-formulation ILP.
To gain more security in application-layer, current firewalls employ deeper inspection into the application layer, which can impact the customer network due to the additional processing burden, especially during traffic peaks or attacks. To figure out the trade-off between the network security and performance, we present a new method in this paper to generate testing traffic for the stateful firewall evaluation which can both be used to explore the boundary performance
of the stateful firewall under certain security level, and characterize a specific customer network to evaluate the performance of the stateful firewall before its implementation to this customer network.
