Ethernet Wiring Standards with Different Frame Size to Enhance the Performance of LAN

International Conference on Aerospace Sciences and Aviation Technology, 2015

Commonly abbreviated Local Area Network LAN is a computer network that covers only a small area networks, such as campus computer networks, buildings, offices, in homes, schools or smaller. Currently, most LANs based on the IEEE 802.3 Ethernet technology using devices such as hubs and switches devices, which have a data transfer speed of 10, 100, or 1000 Mega bit per second (Mbps). In this paper, we will evaluate the performance of LAN under different Ethernet wiring standards (10BaseT and 100BaseT) with different frame size.

Performance Characteristics of Two Ethernets: An Experimental Study

Proceedings of the 1985 ACM SIGMETRICS …, 1985

Local computer networks are increasing in popularity for the interconnection of computers for a variety of applications. One such network that has been implemented on a large scale is the Ethernet. This paper describes an experimental performance evaluation of a 3 and a 10 Mb/s Ethernet. The effects of varying packet length and transmission speed on throughput, mean delay and delay distribution are quantified. The protocols are seen to be fair and stable. These measurements span the range from the region of high performance of the CSMA/CD protocol to the upper limits of its utility where performance is degraded. The measurements are compared to the predictions of existing analybical models. The correlation is found to range from good to poor, with more sophisticated models yielding better results tban a simple one.

A performance analysis of the Ethernet nets for applications in real-time: IEEE 802.3 and 802.3 1 Q

2008 6th IEEE International Conference on Industrial Informatics, 2008

Ethernet technology dominates the local net market of computers. However, it was not established as a technology for industrial automation, where the requirements demand determinism with a performance of real time. Many solutions have been proposed to solve the problem of the no determinism, which are based mainly on the TDMA (Time Division Multiple Access), Token Pass and Master-Slave. It is in this context that this paper carried through measures of performance on communication nets that use the standard IEEE 802.3, observing the behavior of these nets when submitted to different scenes of overload. For this, variations were adopted in the test environment, which will be based on Shared Ethernet (Hub), Switch Ethernet and Switch Ethernet with priority (IEEE 802.1Q). This way, being capable to indicate which devices analyzed among the performance tests demonstrated a more appropriate behavior to support the applications with the time requirements of real time.

An Approach for Enhanced Performance of Packet Transmission over Packet Switched Network

A collision avoidance approach is a mechanism used by LAN (Local Area Network) to control access and allocate shared bandwidth among stations that want to transmit at the same time in a shared medium. There must be some mechanisms by which stations can come to know about that they want to transmit at the same time. Such mechanisms are known as collision detection methods . Ethernet uses CSMA/CD (Carrier Sense Multiple Access/Collision Detection) for collision detection. The use of switch in Ethernet makes it possible to reduce the collision. Certain rules are being followed by the communication process. For example, when a peripheral device wishes to communicate, it sends the request for communication that reaches the switch. If another peripheral device communicates already, two messages are found at the same time on the network. The message from the first host is taken at the beginning of a queue, and the second host waits for trying again to communicate a few milliseconds later . Now a day's Local Area Network (LAN) technology has made a significant impact on almost every industry. Operations of these industries solely depend on computers and their networking. The data is stored on computers than on paper, and the dependence on networking is so high that banks, airlines, insurance companies and many government organizations would stop functioning if there were a network failure. Since, the dependency on networks is so high and the network traffic is increasing, we have to address some of the bandwidth problems this has caused and find solutions to tackle them .

Quality of Service Analysis of Ethernet Network Based on Packet Size

Journal of Computer and Communications, 2016

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.

Design and Implementation of the Packets Transceiver System of Ethernet Mac Layer

NADIA, 2015

As we all know, Network communication is essential in network transmission, while the transmission delay of Ethernet's MAC (Media Access Control) layer will affect the quality of communication networks with the continuous progress and development of Ethernet technology. In this paper, we design and implement the correct receiving and sending of Ethernet MAC protocol layer's packets with FPGA, through the in-depth analysis of Ethernet MAC packets transceiver. The simulation results of the transceiver module system level were given through the simulation test plat form we built, which shows that Ethernet MAC layer's packets designed on the FPGA-based platform can receive and send faster, and the low system occupancy rate can meet the requirements of system throughput for real-time communication environment system, which can provide the technical support for the development of Gigabit Ethernet.

Performance analysis of local area networks

1990

A simulation of the TCP/IP protocol running on a CSMA/CD data link layer was described. The simulation was implemented using the simula language, and object oriented discrete event language. It allows the user to set the number of stations at run time, as well as some station parameters. Those parameters are the interrupt time and the dma transfer rate for each station. In addition, the user may configure the network at run time with stations of differing characteristics. Two types are available, and the parameters of both types are read from input files at run time. The parameters include the dma transfer rate, interrupt time, data rate, average message size, maximum frame size and the average interarrival time of messages per station. The information collected for the network is the throughput and the mean delay per packet. For each station, the number of messages attempted as well as the number of messages successfully transmitted is collected in addition to the throughput and me...
