Modeling using queuing theory

Modeling using queuing theory. if N.R=M then input capacity = capacity of multiplexed link => TDM if N.R>M but ? .N.R<M then this may be modeled by a queuing system to analyze its performance. Queuing system for single server. Inputs/Outputs of Queuing Theory. Given: arrival rate

Multiplexing/Demux

Multiplexing/Demux. Multiplexing at send host:. Demultiplexing at rcv host:. Multiplexing/demultiplexing. delivering received segments to correct socket. gathering data from multiple sockets, enveloping data with header (later used for demultiplexing). = socket. = process.
