Maen ArtimyComments Off on SDN with Raspberry Pi and Zodiac FX
Experimenting with Software Defined Networks (SDN) on real hardware has become a lot easier since I discovered the Zodiac FX switch from Northbound Networks. This 4-port switch supports Openflow v1.0 and v1.3, and it supports many Openflow controllers. This post describes the process of connecting the Zodiac FX switch with… Read more »
This is my latest Android App and the first to be published in Google Play. The App provides you with basic information about any unicast IPv4 address you enter, including: the network id portion of the IP address given the mask length, the number of usable host IP addresses within the… Read more »
Maen ArtimyComments Off on Behind the Wall: The Internet Is The Computer
Back in the eighties, John Gage of Sun Microsystems coined the phrase, “The network is the computer.” Today, the services made possible by the Internet and our use of them as individuals and organizations affirm John’s statement perhaps in ways they were not even imaginable three decades ago. Technology trends… Read more »
Maen ArtimyComments Off on Behind the Wall: The Internet is Made of Light
(this is the third post of the series “behind the wall”. Here are the first and second) The Internet is made of light. That is because the Internet’s backbone is mostly made of optical fibre links that guide light pulses representing data streams. Optical fiber technology permits the transmission of… Read more »
Maen ArtimyComments Off on Behind the Wall – The structure of the Internet
The Internet is a network of networks. Every machine that is connected to the Internet is part of a network. At home, you are likely connected to an Internet Service Provider (ISP). At work, your computer is part of the organization’s local area network (LAN), a network that is… Read more »

Firewalls are the primary defense mechanisms against network security threats. A firewall is a system that can be positioned between any two networks to control the passage of data traffic in and out of these networks. Typically, the two networks are the internal, trusted, network and the Internet [1]. Firewalls… Read more »
Maen ArtimyComments Off on Wireless will become the primary LAN technology
The mainstream consumer market started seeing Wi-Fi products based on IEEE 802.11ac standard in 2013. The standard is the fifth generation of Wi-Fi networking technology that promises more bandwidth to users at home and the office. The new Wi-Fi brings new improvements to wireless networks including offering 1.3Gbps of bandwidth… Read more »
Maen ArtimyComments Off on For safety’s sake let cars talk
Earlier this year, the U.S. National Highway Traffic Safety Administration announced it would begin working on enabling vehicle-to-vehicle (V2V) communication technology for light vehicles [1]. This step is part of the agency’s effort to improve transportation safety and it is a signal to the transportation-related industries to begin the deployment… Read more »
Many applications, especially those that require visualizing complex information, rely on manipulating and presenting data as graphs composed of nodes and links. A graph, in the mathematical context, is a set of objects represented as vertices, or nodes, and a set of links connecting some pairs of objects. The graph… Read more »
