摘要
NetFlow是一种能够获取实际网络中数据流统计信息的技术。通过在OPNET中导入NetFlow格式所表示的实际企业网的流量模式,以测试新增VoIP业务的性能指标。仿真实验对企业网使用最多的G.711和G.729两种压缩技术进行了对比,证明了哪种压缩技术更加适合当前实际网络状况。
NetFlow is a technology which can retrieve statistics information of traffic flow from actual network. By importing traffic flow pattern in actual enterprise network,represented by Netflow format,into OPNET,the performances of newly added VoIP application are tested. Through the comparison between C.711 and G.729,the most popularly used technologies in enterprise network,via simulation,the more suitable technology for current network situation are pointed out.
