Methodology for Benchmarking IPsec Gateways
The paper analyses forwarding performance of IPsec gateway over the rage of offered loads. It focuses on the forwarding rate and packet loss particularly at the gateway's performance peak and at the state of gateway's overload. It explains possible performance degradation when the gateway is overloaded by excessive offered load. The paper further evaluates different approaches for obtaining forwarding performance parameters - a widely used throughput described in RFC 1242, maximum forwarding rate with zero packet loss and one proposed equilibrium throughput. According to the authors', observations equilibrium throughput might be the most universal parameter for benchmarking security gateways as the others may be dependent on the duration of test trials.
