We are excited to announce the winner of Chapterthon 2017.
As we truly believe that Internet Society and our community have an important role to promote the use of the Internet for education, we organized the Chapterthon 2017 on Digital Schools.
Chapterthon is a global Chapters marathon, where our chapters can participate by developing a project within a timeline and budget to achieve the common goal of improving education by using the Internet.
During the past months, 31 Chapters from all the regions have worked hard to extend the education benefits of the Internet to their communities. Connecting schools to the Internet, teaching coding to girls, training teachers and parents, raising awareness about the safe use of the Internet, developing an online platform for a school and helping to create educational, and local content are just some examples of the amazing work our chapters have done.
Each project has proven us once more that the Internet plays an important role in achieving the Sustainable Development Goal on Education. Each project has contributed to shaping the future of children, parents and teachers.
While all the projects have left an important mark on local schools, the Internet Society community members have voted Continue reading

Today’s Steps to Make a Better Tomorrow!
We are delighted to announce the launch of 2016 Beyond the Net Impact Report and 13 amazing new projects.
As we look at the past year, we are proud of the achievements our community has made with funding from the Beyond the Net Programme. We have some great examples of how the Internet can have a positive impact in people’s everyday lives. By building community networks in Africa and Europe, improving Internet connections in North America, or ensuring that people can trust their connection in Asia, we’re contributing to things like closing the gender gap, building partnerships, and helping kids stay in school.
In 2016, we took a huge step forward to consolidate the Beyond the Net Programme. When we see how the Internet can improve the lives of hundreds of farmers in Latin America or how children can develop new skills by learning how to use the Internet in the Middle East, the aim of the program and of our organization becomes crystal clear. The numbers and the stories behind them are a good reminder that the Internet was built as a force for good.
The projects highlighted in this report serve as a critical reminder that as long Continue reading
BGP: the Tragedy of the Commons
Every now and then someone looks at a few recent BGP incidents (from fat fingers to more dubious ones) and says “we need a better BGP”.
It’s like being unable to cope with your kids or your team members because you don’t have the guts to tell them NO and trying to solve the problem by implementing new procedures and rules.
Like anything designed on a few napkins BGP has its limit. They’re well known, and most of them have to do with trusting your neighbors instead of checking what they tell you.
The solutions to the problem are pretty simple and have been known for decades (BCP38 was published in May 2000). In a nutshell you have to:
- Build a global repository of who owns what address space;
- Document who connects to whom and what their peering policies are;
- Filter the updates received from your customers and peers based on the information from those repositories;
- Filter the traffic from addresses that are obviously spoofed.
We have most of the tools we need to get the job done; you’ll find them described in Best Current Practice (BCP) 194. It’s also not impossible to get the job done Continue reading
The Concept of Switch Virtual Interface – SVI
Today I am going to talk about the most widely used to have the interaction between the two VLANs in the switched network apart from router on stick. The topic is SVI- Switch Virtual Interface. As many of the enterprises prefer SVI instead of using the Router on Stick way of communicating the VLANs in the switched network.
Before i started with SVI- Switch Virtual Interface followed by the configuration part, I would like to tell you guys that we have our own youtube channel for various network videos that can further help you guys to study further. I will going to add many more videos soon on the channel, Please subscribe to the channel for the study network related videos.

What is the requirement of the SVI in the Switched Networks ?
With SVIs the switch will use virtual Layer 3 interface to route traffic to other Layer 3 interface thus eliminating the need for a physical router.
In the switched networks, the switches send traffic only to hosts within the same broadcast domain (Single VLAN) and routers handled traffic between different broadcast domains (Different VLANs). This meant that network devices in different broadcast domains Continue reading
