Introduction
Device and hardware support has been improved in many ways for the Microsoft® Windows® XP operating system, which brings together the respective advantages of the Windows 2000 and Windows Millennium Edition (Windows Me) product lines for greater system stability and device compatibility. Windows XP includes Plug and Play support for hundreds of devices not covered by Windows 2000, and enhanced support for Universal Serial Bus (USB), IEEE 1394, Peripheral Component Interconnect (PCI), and other buses. Plug and Play itself has been improved for Windows XP, resulting in streamlined usability and performance, particularly in the device installation process. And while the driver models are largely unchanged from Windows 2000, Windows XP draws from the Windows Me driver models to add Windows Image Acquisition (WIA), a rich interface that facilitates image acquisition from still image devices such as scanners and digital cameras.
This paper highlights some of the major advances in Windows support for common device classes—such as scanners, cameras, audio devices, high-density storage devices and media (DVDs and CDs), and displays—and explains the power management improvements in Windows XP beneficial to both desktop and mobile computer users.

Power Management Improvements

Power Management Improvements
Windows XP offers enhanced power-management features for desktop and mobile computers. Windows XP follows Windows 2000 in supporting the Advanced Configuration and Power Interface (ACPI) specification, which provides reliable power management and system configuration. Windows XP also provides more limited power management support for systems based on the legacy Advanced Power Management (APM) API.
On an ACPI-compliant system, the operating system manages, directs, and coordinates power so the system is instantly accessible to users when needed, while remaining silent and consuming the least possible power when not actively working. In earlier power management architectures such as APM, the BIOS controlled the power state of system devices without the involvement of the operating system.
Devices and applications designed in compliance with the ACPI specification can respond to or request a change in the system power state. For example, an active application or input from a device, such as a mouse, indicates to the operating system that the computer or device is in use. The operating system's power policy manager then allocates full power to the system. Otherwise, the operating system tries to put the computer into a lower power or sleep state. For example, a fax modem can operate while the system is in standby, consuming little energy until the telephone rings, at which time the system can wake up to receive a fax, and return to standby when the system is no longer needed.

Conclusion
Based on simulation results that have been done, we can conclude that EIGRP presented a simple description of
the EIGRP routing protocol, its distinctive characteristics, and Cisco's brief history of open release of specifications.
The network topology used in the testing process was presented in subsequent sections. These basic implementations
can only be run if the router devices are linked with the fastEthernet wire. Thus, this proposed configuration and
network, can be tested and implemented into VMworkstations.

2.1 Enhanced Interior Gateway Routing Protocol EIGRP is a modified Interior Gateway Routing Protocol (IGRP) protocol, an advanced routing protocol developed
and published by Cisco in 2016. EIGRP is an advanced variant of the distance vector protocol with several
characteristics like link-state protocols. As a hybrid protocol, the Cisco core documentation states EIGRP. As distance
vector protocols create neighbour relationships as in link-state protocols, EIGRP opens its table to its environment [8].
Whenever a new router is connected to the network, three phases are followed by EIGRP-neighbor discovery, topology
exchange and router selection. To test the EIGRP routers parameter, hello packet is sent to decide if the router could
become a neighbour. The routers regularly broadcast the topology details in the topology exchange to revise the
topology changes. The topology table for selecting the path based on the cost metric is evaluated by each router. The
path with the lowest value for the cost is chosen. For wide enterprise networks, EIGRP is useful because it requires less
energy compared to that of link-state IGPs. It is one of the best available distance-vector IGPs [9]. Other than that, in
the local topology table, EIGRP maintains something like a successor route and a feasible successor route. The path by
which the packets are forwarded and have the best metric is the successor route. The possible successor route is when
the successor route goes down or has the second-best metric, the router can forward packets. Thus, this is the benefit of
EIGRP; it does not have to send hello packets to figure out another possible path once a route goes down. It just leads
to a potential successor path.
3. Proposed Network The proposed network aims to accomplish the configuration of the network using EIGRP. It is implemented in the
GNS3 platform. Uses this platform to configure the experimental setup, network configuration specification, ping test,
event log, determine the neighbours, topology table of EIGRP and the number of packets sent and received by this
protocol. Fig. 1 shows the designed topology for configuration.

Related Work
Karna et al. [4] did the performance analysis of Interior Gateway Protocol (IGPs) using GNS3. They took ten
generic routers, and calculate the packet loss, jitter, convergence time, end-to-end delay, throughput, one by one on the
three routing protocols. The protocols that have been simulated are RIP, EIGRP and OSPF. On the other hand,
performance evaluation of routing protocol RIPv2, OSPF, EIGRP with BGP has been conducted by Masruroh et al. [5],
simulation proses using GNS3 to analyze the performance of a network based on convergence, throughput, jitter and
packet loss that combine the IGPs with External Gateway Protocol (BGP). While the performance analysis of OSPF
and EIGRP routing protocols for Greener Internetworking was compared and resulting of EIGRP uses fewer system
resources and produces lesser heat, unlike OSPF [6]. Therefore, the resources are saved in networking.
Those researchers did the evaluation and analysis with multiple protocols to make the comparison. But, Kontšek
and Segeč [7] use only EIGRP implementations to test the network's current open-source. The topology consists of 4
main routers which are Quangga, FRR, OpenBSD and Cisco. With these routers, EIGRP is testing the process of IPv4
and IPv6 protocols. The experiment results are that only FRR and OpenBSD implementations of EIGRP are stable, but
they need some more advanced features to complete the feature set.

As in the actual implementation, the simulation was performed at this stage. Topology, which also works as a
simulate on the tool and been developed using GNS3. As shown in Fig. 1, three areas are configured and simulated
with the following objects used in the design.
Area 0
a.
one unit cisco router 2600 (R1) with two fast ethernet ports,
b.
one unit cisco router 2600 (R2) with two fast ethernet ports and two ethernet ports,
c.
one unit cisco router 2600 (R3) with two fast ethernet ports and one ethernet port.
Area 1
a.
two units cisco router 3600 (R4 and R5) with three ethernet ports,
b.
two units PC which connected with two routers.
Area 2
a.
one unit PC which connected to a router, R3.
5.
Result and Discussion
In this simulation, the network address in Area 0 that connects R1 to R2 is 192.168.1.0/24, while R1 to R3 is
192.168.13.0/24, and R2 to R3 is 192.168.48.0/24. Then, in Area 1, R4 connected to R2 with a network address of
192.168.4.0/24, while R4 to end-user (PC2) with network address 192.168.8.0/24. The same router, R4 with network
address 192.168.5.0/24 connected to R5. The R5 link to R3 with network address 192.168.6.0/24 and linked with the
end-user (PC3) with network address 192.168.9.0/24. Finally, in Area 2, PC1 link to R3 with network address
192.168.19.0/24. All of these areas performing the EIGRP routing protocol.
With this topology, the interfacing is performing for each router. Fig. 2 until 4 shows the configuration of network
switching parameters for R1, R2 and R3, respectively. Thus, all routers are connected, and the ping test has been
complete with the simulation results shown in Fig. 5 until 7.

The online program can be completed on a computer, tablet or iPad. The computer screen must be 13 inches or larger. This won’t be a problem for desk tops and laptops. But it means if you are viewing it on a netbook computer with a screen smaller than 13 inches you will not be able to see the full screen.
If you are viewing it on the right sized screen and still cannot see the full screen, click on the white square in the top right corner of the window to check that it is maximised.
If this has no effect, press F11 on the top line of your key board.
Zoom
If you cannot see all elements of the screen, ensure your zoom in your browser is at 100%
