Preliminary

Demand for Internet access today is very high. Good to find information, articles, latest knowledge or even just to chat. The division number for the internet or commonly known in the world of networking is an IP Address has been very low, or is almost gone.

One IP Address need to do with the other IP address or subnet that is different class, it requires a process system to connect the IP Address, namely routing. Routing will create a chain of interconnected networks and the bias communicate well, and the information available in the IP Address will be obtained in any other IP address.

Device or devices used for routing process is commonly called a router. Router consists of both hardware and software must be installed in line or synchronous in order to work well. Routers can be obtained by direct use without having to install the system by using a broadband router or we can use the computer to make the router by installing the operating system or software to create a router with a record of any hardware support for the routing process. Mikrotik is one of both hardware and software vendors that provide facilities to make the router. One is Mikrotik Router OS, this is the operating system that is specifically used to create a router with a way to install it to your computer. Facilities or tools provided in Mikrotik Router Os are very well equipped to build a router that is reliable and stable.

About Mikrotik

MikroTikls [the trade name MikroTik®] was founded in 1995 aiming to develop a system with a wireless ISP. MikroTikls currently has support system with a wireless ISP for internet data path in many countries, such as Iraq, Kosovo, Sri Lanka, Ghana and many other countries.

Experience in installation in Latvia we forge with similar conditions in the countries of the former Soviet Union and other developed countries. Various development has been undertaken to date software available router operating system version 2, which guarantees stability, control, and flexibility in a variety of media interface and routing systems using standard computer as hardware. The software supports a wide range of applications ISPs, ranging from RADIUS modem pool, to the backbone with a DS3 circuit.

MikroTik located in Riga, capital of Latvia, with 50 employees. Mikrotik also run a small ISP, as a media experiment for routerOR software development.

Mikrotik Router OS

Mikrotik Router OS is the operating system linux or unix variants whose primary function for routing, the operating system is equipped with a wide range of complete routing methods. However Microtik Router OS, not an open source under the GNU body. To use this operating system we have to buy a license to Microtik. Purchase a license Microtik Router OS Microtik offered by the company, not so expensive for the standard router OS.

What Ping meaning in Command Prompt (CMD)?

Ping stands for Packet Internet Groper , a utility application that is provided by Micosoft windows which functions as a network connection with a probe -based Transmission Control Protocol / Internet Protocol ( TCP / IP ) , a more complete understanding please look at wikipedia . The function of the program is to test whether ping one computer to another has been connected in a network / not with sends a packet of data to another computer .

The workings of ping is to send an IP datagram to a host who will then receive a reply / response form of round trip time . In the process uses ICMP messages and ping echo reply . Below is an example of what I do ping between computers :

The purpose of the experiment and the results of the ping above are :

# Pinging 192.168.0.1 with 21 bytes of data : we have to ping the IP 192.168.0.1 with 32 bytes of data

# Packets : sent = 4 , receive = 4 , lost = 0 < 0 % loss > , : means packets sent nothing is lost [ 4 sent 4 received ]

# Transmitted data size 32 bytes because it is the default buffer size on windows

# Function of buffers in windows is to look at the time taken to perform packet data transmission [ mean when pinged with a different host then the result will be different ]

# Then what is the purpose of a reply from 192.168.0.1 : bytes = 32 time < 1ms TTL 128 ?

- TTL which stands for Time To Live , which is the maximum time from the computer when reply / reply ICMP packets or also called latency / delay . TTL on windows by default is 128 .
- Why is this limited number of TTL ? it is to prevent circular routing in the network , because it is every time the ping packet through the host's IP TTL value will be reduced by one , until the TTL has a value of 0 . With a value of 0 will discard this packet and drop the TTL expired in transit keterangn .

# The smaller the value of time and the packet loss from the ping results network connection is used the better .



Well that sense , the function and purpose of the ping in the command prompt . Hopefully the discussion of computer science this time can be understood clearly and can provide benefits to you .
