Description
Summary:Network administrators lack the tools they need to understand and react to their changing networks. This makes it difficult for them to make informed, timely decisions regarding network management, capacity planning, and security. These challenges will only increase as networks continue to gain in throughput, become more complex, and encrypt more and more of their traffic. This paper describes the Passive Network Appliance, or PNA, which is our proposed solution to this problem. The PNA provides snapshots of network behavior through time, in a cost-effective manner. The PNA is implemented on commodity hardware and can enforce network policy in real-time at the granularity of network frame arrival. This paper describes the system, and its evaluation in both laboratory and real-world deployments.
