ABSTRACT: Ethernet network, standardized by IEEE
802.3, is vastly installed in Local Area Network (LAN) for cheaper cost and
reliability. With the emergence of cost effective and enhanced user experience
needs, the Quality of Service (QoS) of the underlying Ethernet network has
become a major issue. A network must provide predictable, reliable and
guaranteed services. The required QoS on the network is achieved through
managing the end-to-end delay, throughput, jitter, transmission rate and many
other network performance parameters. The paper investigates QoS parameters
based on packet size to analyze the network performance. Segmentation in packet
size larger than 1500 bytes, Maximum Transmission Unit (MTU) of Ethernet, is
used to divide the large data into small packets. A simulation process under
Riverbed modeler 17.5 initiates several scenarios of the Ethernet network to
depict the QoS metrics in the Ethernet topology. For analyzing the result from
the simulation process, varying sized packets are considered. Hence, the
network performance results in distinct throughput, end-to-end delay, packet
loss ratio, bit error rate etc. for varying packet sizes.
