摘要

本文介绍了一种基于NetCOPE开发平台的COMBOv2卡硬件网络包生成器的体系结构。包生成器的内部结构允许合成的IPv4和IPv6网络包生成以及真实的网络包传输。该发生器基于COMBOv2外接接口卡，传输速率可达2×10 Gbit/s或4×1 Gbit/s。使用高质量的伪随机数生成器生成合成数据。如果需要，可以将先前捕获的网络数据包以与捕获的完全相同的时间漂移传输回网络。这是通过极其精确的时间戳来实现的，这些时间戳可以由NetCOPE平台中包含的Timestamp模块生成。

Precise IPv4/IPv6 packet generator based on NetCOPE platform

This paper presents an architecture of a hardware network packet generator designed for the COMBOv2 cards using the NetCOPE development platform. The packet generator internal structure allows synthetic IPv4 and IPv6 network packet creation as well as the real network packet transmission. Based on COMBOv2 add-on interface card, the generator is able to transmit packets at speed of 2×10 Gbit/s or 4×1 Gbit/s. Synthetic data are created using high quality pseudo-random number generator. If desired, previously captured network packets can be transmitted back to the network with exactly the same time drift as were captured. This is accomplished by extremely precise timestamps, which can be generated by the Timestamp Module included in the NetCOPE platform.
