    Computer networks like internet necessitate network resources, i.e. bandwidth, buffer spaces, etc in order to accommodate the arriving packets at router buffers [25]. When the arriving packets cannot be accommodated due to lack of network resources, this indicates occurring congestion at router buffers of networks [21]. Congestion can deteriorate a network performance [22, 25] through growing the packet loss probability due to overflow as well as the mean waiting time for packets in the queueing

    Local Area Network (LAN) is a communication system connecting hundreds of computers and peripherals within a radius of a few kilometres. Appeared in the 1970s, LAN has experienced a tremendous growth with the development of the microcomputer in the 1980s and the advent of the Ethernet communication standard. Conversely, the wide area network (WAN) can bring together thousands of computers that are separated by hundreds, or even thousands of kilometres. There are also wireless LAN networks. A wireless

    It's a group of computers which all belong to the same organization, and which are linked within a small geographic area using a network, and often the same technology, they can be either wired or wireless. Twisted pair coaxes or fibre optic cable can be used in wired LAN. Also in LAN it uses a protocol, a set of rules that governs how packets are configured and transmitted. LAN is capable of carrying very high transmission rates normally in Mb/s (Megabytes per Second) and Gb/s (Gigabytes per second)
