NDN is a promising protocol that can help to reduce congestion at Internet scale by putting content at the center of communications instead of hosts, and by providing each node with a caching capability. NDN can also natively authenticate transmitted content with a mechanism similar to website certificates that allows clients to assess the original provider. But this security feature comes at a high cost, as it relies heavily on asymmetric cryptography which affects server performance when NDN Data are generated. This is particularly critical for many services dealing with real-time data (VOIP, live streaming, etc.), but current tools are not adapted for a realistic server-side performance evaluation of NDN traffic generation when digital signature is used. We propose a new tool, NDNperf, to perform this evaluation and show that creating NDN packets is a major bottleneck of application performances. On our testbed, 14 server cores only generate ~400 Mbps of new NDN Data with default packet settings. We propose and evaluate practical solutions to improve the performance of server-side NDN Data generation leading to significant gains. |
