Open source software has had a significant influence on the tech career of today's Full Stack Journey podcast guest, Matt Broberg. We discuss why open source has been so influential, the importance of community in IT, and topics such as how to stay technical when your role changes, and why business fundamentals should matter to technologists.

The growing complexity of IT environments make it harder for SecOps teams to keep pace with developers, manage access to resources, and ensure that the right controls are in place and policies are met. Sponsor Tufin joins the Heavy Networking podcast to discuss how automation can boost SecOps effectiveness while tackling initiatives such as zero trust and network segmentation on premises and in the cloud.

BGP PIC ( Prefix Independent Convergence ) is a BGP Fast reroute mechanism which can provides sub second convergence even for the 500K internet prefixes by taking help of IGP convergence.
BGP PIC uses hierarchical data plane in contrast to flat FIB (Forwarding table) design which is used by Cisco CEF and many legacy platforms.
In a hierarchical dataplane , the FIB used by the packet processing engine reflects recursions between the routes.
I will explain the recursion concept throughout the post so don’t worry about the above sentence, it will make sense.
There are two implementation of BGP PIC concept and they can protect the network traffic from multiple failures.
Link, node in the core or edge of the network can be recovered under a second and most of the case under 100ms ( It mostly depends on IGP convergence, so IGP should be tuned or IGP FRR can be used ).
In this article I will not explained IGP fast convergence or IGP Fast reroute but you can read my Fast reroute mechanism article from here.
BGP PIC can be thought as BGP Fast Reroute Mechanism which relies on IGP convergence for the failure detection. ( All overlay Continue reading
[Published on behalf of the Internet Society Board of Trustees.]
The Internet Society’s vision is that the Internet is for everyone. Earlier this month, we wrote about our efforts to ensure a stable and diverse funding model to support the work that takes us towards our vision. The role of the Board of Trustees is to provide, with support from the community, the strategic direction for that work. In this post, we discuss our recent and current strategic efforts, put them into context, and provide pointers with more information for our community to get involved in defining our wanted future.
Naturally, the starting point of our current strategy was to agree with the community on the overall direction. Therefore, two years ago, during 2017, the Board consulted with our community to revise our mission statement into what we have today. Many of you contributed to that 2017 effort, which resulted in the following three focus areas:
Based on that community agreement on the development of this new mission, the Continue reading
I always tell attendees in the Building Network Automation Solutions to create minimalistic data models with (preferably) no redundant information. Not surprisingly, that’s a really hard task (see this article for an example) - using a simple automation tool like Ansible you end with either a messy and redundant data model or Jinja2 templates (or Ansible playbooks) full of hard-to-understand and impossible-to-maintain business logic.
