Service Mesh Interface (SMI)

SMI Traffic Access Control

Traffic Access Control defines the `TrafficTarget` resource, which associates a set of traffic rules with a service identity allocated to a group of pods. It is the authorization layer of SMI: which source identities may speak which protocols/routes to which destination identity. Per the spec, "a valid TrafficTarget must specify a destination, at least one rule, and at least one source."
