This paper proposes a network connectivity model for e-learning environment based on integration a number of modern information and communication techniques for deliver the learning materials between e-learning system-servers and students' clientdevices. The proposed network connectivity model is based on three logical layers, Layer-I use the modern information and communication technologies inside academic building (which includes hardware servers, LMCSs, mobile devices, mobile Tablets and network-based Wi-Fi, in addition to the Smartboard) and integrate all components of the system. Layer-II concerns with connects all local e-learning systems with each other inside campuses as 100Mpbs start LANs topology. Layer-III concerns with connects some of Baghdad city's campuses with 10Gbps mesh network. Many throughput tests had done with UOT Network at ICT Center in University of Technology, with 45Mbps traffic load on hardware, and Mikrotik RouterOS v5 according Ethernet frame sizes 64, 512, 1518 bytes.
