Links are a way of expressing a relationship between one container and another. When you link a container, you create a parent/child rlationship between the two. As a side effect links also allow you to name containers and reference them by name. Containers can be referenced by more than one name.
Initially links will be expressed with the environments of the children being injected into the parent accessible via namespaced environment variables:

REDIS_ENV_{key}={value}REDIS_PORT={value}
