Why don’t you build your own ISP (Internet Service Provider)

Why don’t you build your own ISP (Internet Service Provider)

internet, ISP, tips
In the previous article, we know that the internet cost is actually free, because we just connect to each other at the IXP. However, many internet users are living far from the IXP, which means there is a business opportunity that offers connection from user's devices to the IXP. This kind of company that offer "internet connection" later in is called Internet Service Provider or ISP. In this article, we discuss "why dont you just build your own ISP", get connection to the internet and share it to users with price. (more…)

What is internet? IXP? how it works?

What is internet? IXP? how it works?

internet, telecommunication
First assumption before reading this article is you (readers) already have experience of connecting to internet, either by checking email, browsing website, transfer file, and many other things. In the previous article, you know that we can build a network using devices like router and switches. with network computers can communicate to each other through a media. internet actually, is just a collection of network where computer can access each other.  This article will talk about how internet works.

Do you really need a layer 3 switch? don’t have to be tricked by sales guy…

Do you really need a layer 3 switch? don’t have to be tricked by sales guy…

layer 2, Layer 3, Router, switch
So one day, after attending a Mikrotik User Meeting in Indonesia, i had a chance to have a talk with an employee of a retail company in Bandung. H told story about a network implementation project on his company, where they put Mikrotik as main router to forward traffic between internal networks, and the networks were created with the help of VLAN technology. ok sound cool so far... he then continued confidently "we use a cool layer-3-switch that makes our network stable". "ok" i nodded, "so what did you configure on your fancy layer-3 switch", i replied. and he said, "well, we configure VLANs there, and route the traffic using our mikrotik router" (that means he just configured the layer-3-switch for VLAN only. all traffic between network or inter-VLAN traffic…

The word "attack" is not only belong to martial arts or military. In IT world we also use this term "attack" to describe an action that is done by a system to damage or destroy the target system / network. In this article we will discuss what is cyber attack: DOS, DDOS, bruteforce. these attack usually related to each others. (more…)

What is managed switch?

layer 2, Routerboard, RouterOS, switch, SWOS
Previously we already know that there a network devices called switch. which could improve a network performance especially in ethernet technology. You already know that network segmentation can be done based on port using VLAN technology with the use of router for inter-vlan routing. Normally, to configure VLAN on a switch is by connect to it physically. However, this practices is annoying because we have to come on site for configuration. switch vendors then make switches that can be controlled from remote place and later on its called managed switch.

Mikrotik roles on VLAN

Mikrotik roles on VLAN

layer 2, Routerboard, VLAN
So we already know what the VLAN is from this article and also aware VLAN is actually just a layer 2 technology that enables flexibility of partitioning your network. With VLAN, you can partition your switch logically using web or command line interface. next question arises, so what Mikrotik routerboard do to support VLAN? Mikrotik roles on VLAN? (more…)

June 2017, GLC Webinar: Configuring Mikrotik Hotspot

June 2017, GLC Webinar: Configuring Mikrotik Hotspot

webinar
Configuring Mikrotik Hotspot. In this webinar, we discuss a feature from mikrotik routerOS that is called hotspot. This feature enables administrator to provide web-based authentication for clients. Hotspot login page can be modified to customer need. walled-garden allows clients to access website without authentication, and radius feature enable hotspot to query external radius server for account.

Routerboard selection guide: switch

Routerboard selection guide: switch

layer 2, Layer 3, Router, Routerboard, switch, SWOS
So, many years ago (before 2014), Mikrotik just produced switches for small network. Therefore, when we build a network that requires high-port density (requires many ethernet ports), we use products from other vendors. Mikrotik at that time was used as a routing device. This article will talk about Routerboard selection guide: switch But now in 2017, mikrotik product portfolio has improved, and you already see some switches products on the list. Why ethernet switch? Not token ring or other? Because Ethernet is the technology that people use most. Its cheaper, easy to get and install, and still evolving to support higher and higher data rate. That is why Mikrotik produces ethernet switches. (more…)

What is VLAN?

What is VLAN?

layer 2, VLAN
Ok before we talk about "what is VLAN", we already know the cool layer 2 devices, which really help us reducing collision domain. Network performance is improved and users are happy :-). most of the picture in this articles are taken from this GLC webinar. [caption id="attachment_566" align="alignnone" width="300"] Physical LAN[/caption] Up to this point (using a dumb switches), we are segmenting network based on the physical switches aka. Physical LAN - PLAN. The more segments you need, the more switches you buy, the router is used to forward traffic between LAN. Just like the picture above. (more…)

Routerboard
All right, so from the previous article, we already know that Mikrotik is producing networking hardware named Routerboard. now its time to discuss Routerboard selection guide ethernet router. Why ethernet router? Not token ring or other? Because Ethernet is the technology that people use most. Its cheaper, easy to get and install, and still evolving to support higher and higher data rate. That is why Mikrotik produces ethernet routers. (more…)
