| Abstract: | Modeling of communication networks and its emulation based on computer local area network (LAN) are discussed in this paper. Not only the network performances (e.g. throughput), but also the quality of services (e.g. error and delay etc.) is considered as the aims of an emulation system. A four node SDH ring is emulated on two stations Ethernet LAN in order to research the features, especially the speedup, of LAN for emulation of large scale communication networks. It is shown that the effective velocity of communication between processes in two computers is not less than 1 Mb/s. |
