G.8032 RPL Type/Node

B.

G.8032 is an ITU-T standard for Ethernet ring protection. It defines a mechanism for fast fault recovery in Ethernet ring networks, providing protection against failures of nodes, links, and ports.

In G.8032, a ring is composed of nodes that communicate with each other in a specific way to detect and recover from faults. Each node in the ring is assigned a specific role, and the correct role for each node is crucial for the correct operation of the ring.

In the context of G.8032, a "RPL" (Ring Port Link) is a virtual link that connects two adjacent nodes in the ring. A RPL can be of different types, depending on the role of the nodes that it connects.

The four options presented in the question refer to different types of RPLs, as follows:

A. RPL peer node: This type of RPL connects two adjacent nodes that have the same role in the ring. Specifically, a RPL peer node connects two nodes that are both "Transit Nodes" in the ring.

B. RPL owner node: This type of RPL connects a "Transit Node" to its "Protection Node" in the ring. The owner node is responsible for monitoring the status of the ring, and for switching the traffic to the protection path in case of a fault.

C. RPL uplink node: This type of RPL connects a "Transit Node" to an "Uplink Node" in the ring. The uplink node provides the connectivity to the rest of the network, and it is responsible for forwarding the traffic towards its destination.

D. RPL next-peer node: This type of RPL connects a "Protection Node" to the next "Transit Node" in the ring. The next-peer node is the first node that receives the traffic after it has been switched to the protection path.

Therefore, the correct G.8032 RPL type/node depends on the role of the node in the ring, and the type of RPL that is required to connect it to its neighboring nodes. In this case, the correct answer cannot be determined without additional information about the topology and configuration of the Ethernet ring network.
