access-spoke circuit,

Пожалуйста, помогите перевести.
access-spoke circuit,
Выражение встречается в следующем контексте:
HVPLS offers the following advantages:

- reduces the complexity of mesh configuration
- decreases the amount of signaling of routes between devices

When traffic arrives at an access-spoke circuit, it acts like a bridge port where flooded traffic received on the access spoke is replicated to all other spokes, meshes, or SAPs but it is not transmitted on the port where it is received.

Заранее спасибо
