o
Ring : A Ring is an Ethernet ring that is connected on two ports (East and West service points) to an
interconnection node.
o
Sub-ring : A Sub-Ring is an Ethernet ring which is connected to another ring or network through the use of
interconnection nodes (East and West service points). On their own, the Sub-Ring links do not form a
closed physical loop. A closed loop may be formed by the sub-ring links and the link between
interconnection nodes that is controlled by other ring or network.
o
Ring with sub-ring : The ERPI includes both a ring, with East and West service points, and a connection to a
sub-ring using a Sub-Ring service point.
