Service Mesh Networking	concept	Service Mesh Networking	What a mesh actually does at the network level, the cost per hop, and the shift from sidecar to shared-proxy models.
Traffic Splitting	pattern	Service Mesh Networking	Directing a defined percentage or subset of requests to a different version of a service, configured at the routing layer rather than in application code.
