| Abstract: | 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, this paper tests the performances of newly added VoIP application. Through the comparison between C.711 and G.729, the most popularly used technologies in enterprise network, via simulation, this paper points out the more suitable technology for current network situation. |
