With GTP they use  TEID to get good hashing over fibers in a bundle. This is typically just configuration and mostly we use switch/router instead of pure switch. We had same challenges with load balancers and firewalls but all now scale and hash for GTP.

How complex are those optimisations? Cannot be adapted to any other encapsulation solution (usually is just a hash….)

Security is a broad term, can you be more specific?
