Referat: Making SDN better with IPv6 («RIPV13»)
Contrary to what the networking and virtualization vendors claim, SDN (software-defined networking) isn’t an amazing new discovery but an interesting rehash of old ideas (after all, we had controller-based networks in the days of IBM mainframes). Even worse, most vendors shipping so-called software-defined solutions implement them first for IPv4, grudgingly adding support for IPv6 years later when the customers force them to face new reality. Not surprisingly, trying to reinvent old technologies and forwarding paradigms rarely ends well.
There are a few notable exceptions, from network operators like Deutsche Telekom building fully-automated IPv6-only networks to cloud providers using the extra address space provided by IPv6 in novel ways to implement fast container networking or service mobility.
The short presentation by Ivan Pepelnjak will start with a brief recap of what SDN is (and is not), describe why most SDN solutions should be protocol agnostic (it shouldn’t matter whether they use IPv4 or IPv6 addresses to forward traffic), and finally how one can creatively use the unique properties of IPv6 to implement novel solutions like better load balancing in leaf-and-spine fabrics and service mobility with Identifier Locator Addressing.
