The entire methodology to analyze and see-through the dynamics of networking within a corporate or public sector, where a series of systems are tangled with each other for access to a common network, is called network monitoring. It is basically done to ensure the proper functioning of hosting computers in accordance to their network services. This practice can be conferred as an example, at university IT networks.

Network monitoring software , specifically monitors the performance graph of devices or connections. Under any case, whether failures or errors, it detects, elicits and reports the outcome. This software places a curb over the CPU utilization of the host computers, link utilizations, and other operational aspects. One of the mediums through which it does so is that it sends certain request messages to the network of each hosts and thus ensures by measuring the responses to each requests sent.

These messages are termed as ‘watchdog messages’. If in the case of failure, slow responses or any other behavior which is unexpected, it then sends additional messages which are called ‘alerts’, to the pertinent locations such as the main server, phone number or email address to hasten up for the notion of that glitch.

Ping is one of the most commonly used software for network monitoring for simplified networks. Ping is used to send IP based test messages between the host computers. Any system (connected to a specific network) can run ping testing to ensure its connectivity and plus the overall connection performance. For intricate or professional networks, relatively sophisticated software packages e.g. HPopenview and LANdesk are used for network monitoring.

Another type of network monitoring software is focused on monitoring the availability of Web Servers. Larger enterprises which are into the usage of a broader pool of web servers and distributed world wide; this type of the software promptly acts as a sleuth, for detecting problems at any location. An expedient example for such case is ‘mon.itor.us’ which is available on the internet.

Some of the important checklists that are to monitor within the network are network tomography, route analytics, types of protocols and already mentioned; servers around the globe. Adding to this, free available network monitoring software examples are bandwidth monitor, serversAlive, sysinternals DiskMon, Sysinternals ListDLLS etc.

There are many popular software that are used to monitor the network bandwidth. These software tell you the exact utilization of your network resources.

DSL known as (digital subscriber line) basically performs a function of transferring digital data through the lines of telephone. Read it all..

Well there are numerous things when it comes to comparison of different broadband. Some of the factors that play a very crucial role are as follows: Read it all..

There are lots of things that can be tested in a broadband speed test such as the download and the upload speed, networks, latency, DNS servers and ping time.

First most important thing that is measured in a broadband speed test is the download speed. Download speed shows how fast the connection can deliver content to your computer or the local area network. Read it all..

The basic working methodology of BROADBAND is as follows:

1. Basically the first essential thing is the modem that is used to connect and will be attached with the users personal computer.
2. Secondly if you want to connect to more than one telephone lines than a splitter is required that usually splits up the voice with the ADSL and makes sure that interference is not created at any level.
3. These splitters are than connected to the telephone wires which may be above or below ground level depending upon the location. These telephone lines are connected to a DSLAM or know as telephone exchange.
4. When the telephone line is connected to the exchange it serves the same purpose by separating the voice in the same manner as the splitter. All the DSL lines are connected to DSLAM in the telephone exchange which than passes it to multiple customers.
5. The local exchange is like a cloud because here there are multiple tons of networks.
6. The local exchange is connected to a gateway this is the point where all the terminals are terminated. There are different sizes of gate ways depending upon the traffic sizes. The most common gate ways that are being used are of 34MBS or of 155MBS. The 155MBS can support up to around 7000 customers.
7. Now the ISP is connected to the gate way. It can be connected to the gateway in different ways. There are two ways in which gateway can be connected either through an Ethernet or a gigabit Ethernet. Like for example if your ISP is of around 155MBS than Ethernet wont work the only thing that will work in such case is the gigabit Ethernet.
8. Once your ISP is connected the BROADBAND is in proper working condition.

The ordinary phone lines normally can transfer fewer amount of data from one place to another which is around 29.6kbps but as the time passed on consumers demanded a much faster and easier way for speedy data transmission so broadband fulfilled that purpose.

So if the ordinary telephone line has a single channel to carry data at the same time broadband has the ability to carry multiple channels hence transferring data at a higher speed. It’s just like a tunnel the broadband is a big tunnel that allows flow of information and telephone is a small tunnel that allows less amount of information flow.

The most recent technology these days is the wireless broadband which allows an internet access and transfer of data to a much larger extent. Most wireless broadband have an access facility of around 50km. initially the wireless internet facility was being adopted in the rural areas where it was very difficult for DSL to reach.

To simply use the wireless internet service the consumer’s just place a dish or some sort of signal catcher in front of the transmitter that provides the signal and passes it through to the consumer. Basically the wireless modem receives the services and than convert these services into radio signals so if a consumer is connected in that area signals are transmitted to him.

Most commonly the wireless internet is being used in laptops the only thing required is the broadband adapter. What happens is that the adapter once connected starts searching for wireless signals and when it catches the signals it tries to connect it self with it.

If there is no security protection than their would be an easy connectivity between the two. Mostly the wireless broadband is protected with some sort of security otherwise customers would just use the facility and increase the customer traffic. To avoid such thing now a days high security software’s are used to protect unknown users from connecting the wireless internet facility.

Wireless broad band makes it much easier for the users to use the internet. Simply following things are required to connect through a wireless network:

• Wireless modem
• Router
• Switch

Wireless broadband is very common now days and is being used by large organizations as well as chain hotels. The basic workable function of wireless broadband is that a consumer connects itself through some sort of a signal catcher or a transmitter. The transmitter catches the signals in the form of radio signals and than it passes it through to the router and than to the modem. The modem than connects the consumer with the transmitter.

In early phases DSL was most commonly known as digital subscribers loop but since it has gained lots of popularity it is now known as digital subscribers line. The basic function of DSL is that it provides digital data to pass through the lines of telephone. DSL has this unique property that it can be used with the telephone line without disturbing it. This unique property is due to the fact that DSL usually uses very high frequency while the ordinary telephone operates at a low frequency as compared with the DSL. The performance of DSL depends upon two things:

1. What service level is adopted?
2. What is the condition of line?

The working of DSL is basically in two very simple steps. DSL divides the frequencies that are used in a telephone in to two parts. First is the ISP data which is carried through the higher frequency and the second which is most important is the voice which is carried over through the low frequency. This is the only reason the DSL modem and the telephone lines can be used together. The basic working of the DSL is as follows:

• First of all DSL modem is attached to the customer’s phone line.
• Now the telephone company connects the other part of the telephone line to what is called as DSLAM.
• When the DSL modem is switched on it does a self test.
• It normally checks the connection between the DSL modem and the sender.
• In the last phase the DSL modem tries to synchronize with the DSLAM.

The basic function of the DSL modem is that it converts the digital data into small voltage signals that can be used in the phone lines. In very few cases some DSL do require some sort of filters to be installed. These filters are installed at the telephones near the customer residence. There are lots of digital subscribers technologies like:

1. ISDN
2. HDSL
3. SDSL
4. ADSL
5. ADSL2
6. ADSL++

DSL carries a download speed from around 256kbit/s to almost around 28000kbit/s and it varies.DSL is the latest technology that is being used for high speed connectivity and optimum performance.

Broadband these days is very widely used in telecommunication these days. Its basic function consists of providing signals by handling wide range of frequencies. These frequencies can be than subdivided into frequency bins. It has a very simple working principle the larger is the bandwidth larger amount of information it can carry. Broadband is used in several different areas for example:

1. Telecommunication
2. Data communication
3. DSL
4. Ethernet
5. In power line communication
6. In video

In data communication broadband serves as source to handle numerous pieces of data to increase what is called the transmission rate. The basic function of broadband in DSL (digital subscriber line) is that it can transfer the digital information to a very high bandwidth channel. The common interface that is used for the broad band modems is the Ethernet which is used for DSL as well as cable net. Now a day’s power line communications are also being used.

So the basic function that the broad band performs in the power line communication is to achieve very high data rates. The basic difference between broadband and the dialup is that the dialup modems are limited to bit rates while broadband provides much greater speed without disturbing the telephone line. Now why broadband is called high speed internet because it has the ability to transfer data at a very high speed. Basically broadband is anything higher than 256kbit/s.

The common term that is used in broad band is data rates. Data rates are typically defined as maximum number of download. Broadband technologies which are common in most areas are DSL and cable modems. Many newer technologies are coming up like VDSL and optical fiber. In most of the areas where people face a difficulty to install DSL or cable modems they are using what is called as WIFI.

Broadband is very commonly used these days in mobile networks other than the computers. The technology that is used in mobile networks is called as WIMAX. There is no set definition regarding broadband with respect to bandwidth but mostly anything above 786kbit/s is considered as broadband. So broadband plays a very vital role in telecommunications and is spreading at a very high pace all over the world.
