Here are some key advantages and disadvantages of network virtualization:
Advantages:
- Increased flexibility and agility. Virtual networks can be quickly created and configured on demand. This allows for rapid provisioning of test/development environments and easier configuration changes.
- Improved resource utilization. Virtualization allows multiple virtual networks to utilize the same physical networking hardware, improving overall utilization of switches, routers, and other devices.
- Simplified management. Virtual networks can be centrally managed as logical entities rather than individual physical devices, reducing management overhead.
- Enhanced availability. Virtual networks and workloads can be live migrated in case of hardware failures to ensure continuity of operations.
Disadvantages:
- Performance
Computer network is nothing but a set of computers connected to each other, mainly for sharing information,data, programs and resources. Networking reduces the cost of doing business since resources are utilized to maximum extent. Broad categories of networking are LAN,WAN,MAN,STAR,BUS, Ring Topology among others.

Practical Troubleshooting and Problem Solving of Ethernet NetworksLiving Online
While the basic structure of Ethernet has not changed much, the faster technologies such as Fast Ethernet and Gigabit Ethernet have increased the complexity and choices you have available in planning and designing these systems. As Ethernet has become more complex, a number of misconceptions have arisen as to how Ethernet functions and how the system should be optimally configured. This manual addresses these issues in a clear and practical manner, thus enabling you to apply the technology quickly and effectively in your next project. This manual commences with a brief outline of the Fundamentals of Ethernet and its operation.
The method of access is discussed in depth, and topics such as full duplex and auto negotiation are explained. The best methods of designing and installing the cabling systems are then explored with the discussion ranging from 10Base-T over twisted pair to Gigabit Ethernet cabling. Methods of optimising Ethernet to obtain best performance are then defined. Finally the all important topic of troubleshooting is examined with a summary of the typical problems you are likely to encounter from a two station network all the way up to a system comprising 30,000 PCs.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel.

These two layers perform routing and deals with end to end issues. The hospital currently uses a
CISCO ASA 5510–VPN router to connect to the internet. Finally the session layer, presentation
layer, and application work together to make the network operational. These three layers actually
make all the data be visible to the end users. These layers also make the data and network usable to
the operator. Patton–Fuller utilizes Windows Explorer and its company's webpage for these layers
(Patton–Fuller, 2013).
Recommended Protocols For Patton–Fuller to fully utilize their potential networking power, the
following protocols should be utilized. Patton–Fuller should utilize a Gigabyte Ethernet Network for
all its hardwired LAN connections. Gigabyte Ethernet is part of the family of Ethernet computer
networking and communication standards. The Gigabit Ethernet standard supports a theoretic data
rate of 1 gigabit per second. Gigabyte Ethernet networks are connected by CAT5e and CAT6 cabling
(Gigabit Ethernet, 2013). The Gigabyte Ethernet network should be accomplished by using layer 3
switch. A layer 3 switch is a high–performance device for network routing. Layer 3 switches
actually differ very little from routers. A Layer 3 switch can support the same routing protocols as
network routers do. Both inspect incoming packets and make dynamic routing decisions based on
the source and destination addresses inside. Layer 3 switches improve on the performance of routers

which takes place at the application layer also known as layer 7 of the OSI model. It is a protocol
that is used to communicate to and from the NAS (Network Access Server) and also to the AAA
server. RADIUS was developed as access server authentication and accounting protocol. It is used
as both a client and server protocol that is also a software that allows remote access to servers to
allow servers to communicate with the main server, by doing this it allows the server to authenticate
dial–in users and allows authorised access to the services that was requested. RADIUS is an industry
standard that is used by a various number of network product companies, it is also a proposed IETF
standard. The RADIUS is known to be considered as a connectionless service How RADIUS works
RADIUS server's support 's various types of authentication methods to allow a user to have
authenticated access, by using the user's username and password. Some of these authenticated
methods are the Point–to–point protocol (PPP), Password Authentication Protocol (PAP) or
Challenge Handshake Authentication Protocol (CHAP) and there are other methods of
authentication that could be used with RADIUS. When a user tries to log in it sends a query –

40. Main Types Of A Network
Part One: Hubs: Hubs are used to construct a network by connecting multiple computers in a star /
hierarchical network topology, the most common form of local networks now every day. A hub is a
simple device when it is sent bits of computer data from A to B, it is not to examine the purpose,
instead, it sends the signal to all other computer (B, C, D ..) within the network. B will then get it,
while rejecting the other nodes. This confirms that the traffic is released. Hubs works in the Physical
layer in TCP/IP protocol stack. There are two main types of stroke: 1. Liability: The signal is
transmitted as it is (it does not need power). 2. Active: The signal is amplified, so they function as a
repeater. In fact, they were called a multiport repeater. (PSU) Hubs can be connected to expand the
network to other platforms with an uplink port. Switches: Switches place the other side are more
advanced then hubs, Instead of diffusion through the frame, a controlled switch makes for the
destination MAC address and forwards the appropriate port only reach the computer. In this way,
switches reduce traffic and divide the collision domain into segments, which is very suitable for
busy LANs and protects photos, from other computers sniffed the same segment. A table with the
MAC address belongs to which segment is built. If a destination MAC address is not in the table, it
sends all segments except the source segment. If the same objective as the source of the frame is

Data security: Magnetic fields and current induction work in two ways, they just don't generate
noise in signal carrying conductors; they also let the information on the conductor to be leaked out.
Since there are no radiated magnetic fields around optical fibers; electromagnetic fields are confined
within the fiber. This makes it impossible to tap the signal being transmitted over fiber cable. Thus
the fiber cable is the most secure medium available for carrying sensitive data. iii. Non Conductive:
A serious concern with outdoor cables in certain computer networks is they can be hit by lightning,
causing destruction to wires and other cables that are involved in the network. Fiber optic cables can
be made non–conductive by avoiding metal in their design. These kinds of cables are economical
and standard for many indoor applications. Outdoor versions are more expensive since they require
the special strength members, but they can still be valuable in eliminating ground loop and

Learning bridges also age address–table entries by deleting addresses that have been inactive for a
specified amount of time.
The bridges within the network are transparent to users. Packets are sent through the bridge
automatically. In fact, users have no idea that their packets are traversing a link leading to a different
location.
Bridges Versus Access Points
Access points connect multiple users wirelessly to each other and to a wired network. Several users
equipped with 802.11 NICs might associate with a single access point that connects to an Ethernet
network. Each of these users has access to the Ethernet network and to each other. The access point
in this case is similar to a bridge device, but the access point interfaces a network to multiple users.
A bridge interfaces only other networks.
It's possible to use a wireless bridge indoors. A wireless LAN bridge can interface an Ethernet
network directly to a particular access point. This might be necessary if few devices, possibly in a
far–reaching part of the facility, are interconnected through Ethernet. A wireless LAN bridge plugs
into this Ethernet network and uses the 802.11 protocol to communicate with an access point that is
within range. In this manner, a bridge enables the wireless connection of a cluster of users (actually
a network) to an access point.

70. A Brief Note On The Quality Of Service
Abstract: The Quality of service in general refers to capability to provide flawless, fast and
consistent communication across the network. The factors that influence QoS are error rates,
bandwidth, throughput, transmission delay, availability, jitter, etc. Any network must provide secure
and reliable service and to achieve this it needs to consider the above factors. Hence we can say that
the QoS of a network is a set of factors to efficiently use the resources of the network. I am using the
above factors to measure the QoS of different networks and compare them.
Introduction:
In recent times Quality of Service has emerged as one of the important topics for research. QoS can
be defined as the all round performance of a computer network. Any network is expected to provide
secure and reliable service. QoS helps provide better service and this can be made possible either by
increasing the priority of a flow or by decreasing the priority of another flow and this flow can be
managed by using congestion management mechanisms. If a network capacity is insufficient then
the QoS becomes an important factor, for example for real time streaming multimedia applications
like Skype, online games, youtube etc., as in such applications if the delay is too much then the
purpose of the application will not be served. The factors that influence Quality of Service are: Error
rates Bandwidth Throughput Transmission Delay Availability Jitter

ENGINEERING MANUFACTURER Introduction: EngCo Company manufactures components for
the oil and gas industry. It is a cross–discipline engineering company, which combines electrical,
mechanical and process engineering skills. The purpose of the company is to produce custom–made
components for large gas and oil companies across the globe. The company needs a design to set up
their data network. A report is needed to be written where the options for setting up their network
will be outlined, including details of how all services will be provided. Task–1: Physical Topology
Diagram a) Chosen Topology:Network topologies are categorized into the following basic types: 1.
Bus Topology 2. Star Topology 3. Ring Topology 4. Mesh Topology Among them Star Topology is
more suitable for this network. b) Explanation of Choosing Star Topology: In Bus Topologyall
computers are attached to a single cable. So if any of the connection breaks down, the entire
network breaks down with it. It is difficult to move and change since they are all link up together. It
's difficult to troubleshoot (justfortest.tripod.com, n.d.). In Ring topology, Data moves in a one–way
path only. It is expensive because multiple cables area needed and difficult to reconfigure. Simply
not fault tolerant because a single cable fault can bring down the whole network

Core The core layer is the backbone layer of the network running at high speed switching,
transferring large amounts of data and also handling the requests of the distribution layer . This layer
has high speed devices; the most implementations have layer 3 switches or high end routers. Its key
characteristics are: redundancy, fast transport of large amounts of data, high reliability and
availability, low latency. The core layer should not do any packet manipulation.
The distribution layer acts as a services and control border between the access and core layers. This
layer is the place where routing and packet manipulation, policy enforcement, access control are
performed. The distribution also has high redundant connectivity, both toward the access layer and
also the core layer. In this section, layer 3 switches or routers are typically used. ... Show more

To comprehend the risk that sniffers show first requires understanding how sniffers work. The way
in which sniffers work relies on upon the kind of system. In a mutual media system, for example, a
standard Ethernet, parcels sent along a system fragment travel all around along the wire. Any host
associated with a fragment is equipped for catching all sessions inside of that section. For instance,
Exhibit 1 portrays a sniffer–able host. It can catch any activity that experiences the system section,

These factors will impact on the network costs, speed, infrastructure, and functionality. When
designing this Local Area Network (LAN) for DesignIT, there is also need to consider the network
requirements. The network should integrate sound, video, synchronous, as well as asynchronous
data. When designing the LAN network, the organizational goals of DesignIT should be factored in
the LAN design. I will also pay attention to network throughput, line charges, security, and the
integration of newer technologies in the future. When designing a LAN network, some issues must
be considered, one of these issues is the organization's short, medium, and long term goals. Several
factors to be considered include the network equipment, user applications, end–user equipment
(workstations), and connectivity to the internet.
The LAN network for DesignIT will include other network devices which include gateways, routers,
firewall, and cables. Without these devices communication cannot be possible from a computer to
another in the LAN network. A router and switch are the most important devices of a network.
Networks which are well configured and have a good infrastructure are helpful in improving
manageability, performance, reliability and reducing overall operating cost (Kenyon, 2002). To set
up this LAN network for the DesignIT, the following are the hardware and software devices that I

82. The Importance Of Uplink Over Utilization Protection
Uplink over utilization protection – It's important to establish thresholds when looking at both short
and long term utilization and growth of the network infrastructure. Doing so eliminates guesswork
and provides a clear understanding of when additional resources should be required. Specifically
speaking, a threshold is normally based on percentage of usage (in comparison to the maximum
available bandwidth). Example; 50% of 100 Mbps translate to 50 Mbps of overall usage. When
establishing a percentage threshold, it's important to consider things like "margin of safety" and
"historic growth rates". In the case of "margin of safety", the threshold number should be high
enough to alert that more bandwidth will be needed, but low enough to ... Show more content on
Helpwriting.net ...
One other thing to note regarding bandwidth, the difference between 100 Mbps and 1 Gbps is
capacity, not speed of operation. A 100 Mbps Ethernet connection is capable of passing 100
megabits of data in a one second period. In comparison a 1 Gbps is capable of passing 1 gigabit of
data in a one second period. The actual speed of the data is the same, it's just capable of passing
more data in a one second period. (Think of 100 Mbps connection as a single lane road with a 1
Gbps connection as a multi–lane highway with the speed limit of both roads being 55 Mph). In this
example more cars can travel on the highway as compared to the single lane road, but are still
traveling at the same speed.

General bandwidth utilization guidelines
As a general rule of thumb, the chart below (see figure 1.1) shows a general guideline indicating the
peak percentages of utilization on a LAN or WAN, and what (if anything) needs to be addressed
depending on peak utilization. With regards to peaks, another factor needs to be mentioned, and
that's the frequency of peaks. The frequency of peaks defines how often the peaks occur. This is an
important point as the higher the frequency the sooner the potential need for more
