On today's Heavy Networking podcast, guest Cory Steele visits the podcast to make the case that overlays such as LISP offer unique benefits for the network. Greg Ferro disagrees, and makes the case for protocols like QUIC, TLS, and IPSec, and argues for the concept of end-to-end connectivity as the IP network was intended. The post Heavy Networking 516: Is LISP The Overlay Of The Future? appeared first on Packet Pushers.
Today’s podcast episode is a debate on network overlays.
The industry has seen the rise of overlay networking in the data center (EVPN, VXLAN and others), and many SD-WAN solutions rely on overlays. We’re also seeing overlays make their way into the campus; for example, Cisco’s SD Access campus fabric relies on LISP.
Guest Cory Steele visits the podcast to make the case that overlays such as LISP are the way to go. Greg Ferro makes the case for overlay protocols like QUIC, TLS, and IPSec, and argues for the concept of end-to-end connectivity as the IP network was intended.
Cory is a senior consultant and network engineer.
They discuss:
* The pros and cons of “map and encap” protocols such as LISP
* Why LISP may not scale
* The challenges of endpoint mobility
* Practical applications of LISP
* The failures of past protocols
* More
