Upcoming Internet Challenges

Most engineers consider explosive traffic growth and widespread use of mobile devices the most critical threats to the stability of the global Internet. They are not wrong: widespread use of mobile devices forced us to deploy IPv6, and while the mobile service providers and large cloud properties already completed the transition, the rest of the industry still lives in denial.

Unfortunately, we're facing deeper structural problems. TCP/IP stack has broken architecture that’s almost impossible to change and causes explosion in global routing tables. BGP, the cornerstone of global routing, lacks security features ... and the commercial realities of the Internet make it almost impossible to enforce changes that would be badly needed.

Prerequisite knowledge

The webinar relies on basic-to-intermediate knowledge of IP addressing, IP routing architectures, TCP/IP protocol stack and the role BGP plays in the Internet. In-depth understanding of any of the aforementioned technologies is required, but you’ll definitely benefit from a prior exposure to them.

About the webinar

The session was informative and "entertaining". It clearly stated the many challenges of Internet today, however I would have liked to hear more about possible solutions. :-)
