## AI overview

The article discusses using LISP with PUBSUB for multilink mobility in ground-to-airplane networks. It argues that LISP may handle frequent mobility events, scale, and safety-critical requirements better than BGP in this use case, while noting that several protocol extensions and standardized reliable transport are still needed.

## Source excerpt

Béla Várkonyi is working on an interesting challenge: building ground-to-airplane(s) networks providing multilink mobility. Due to its relative simplicity, he claims LISP works much better than BGP in that environment. In some newer routers BGP would not be such a big bottleneck, but you need a lot of knob turning in BGP to get it right, while in LISP it is quite simple. If you have many thousands concurrent airplanes with multi-link and max. 16 subnets with different routing policies on each, and the radio links are going up and down, then you have a large number of mobility events.
